I believe you have it backwards in that the heat should be turned to max heat so to flush heater core. Turning the ac on could cause engine to overheat prematurely. I have 46 years experience as a mechanic. Don't forget to burp the system of air bubbles which can lead to overheating on Honda/Acura. Another reason the heat needs to be on max heat is to get air bubbles out of the system. Great video otherwise.
I am glad that you mentioned it. I was going to say exactly the same thing. I would also add burping the coolant by pressing the hose and perhaps running the engine while filling the radiator and if you don't have to lift the car, drive it with the flush water around the block to increase the flushing effect.
First, absolutely PERFECT (except for that part about flushing with distilled water which dilutes your final result and turning the temperature back and forth between cold and hot. Just leave it on hot.). I live in the snowbelt so I'll need the full 50/50 mix. You showed me what to look for and where it is located which takes the mystery out of doing something new. A lot of folks were worried about trapped air in the system which you didn't have a problem with. I suspect that having the front end jacked up allowed all the air to travel easily up to the filler and escape. Without seeing your video, I probably would have left my front end on the ground and had all sorts of airlock problems. Thanks for the help.
Thanks for the video, but... Honda does not recommend flushing the coolant. After 10 years, you drain the rad and block as Jeff shows. Then you simply fill with blue type 2 coolant. This is why the service period from then on becomes 5 years; you will be using a mix of new and old coolant. When you flush with distilled water (never boiled water), and then add premix coolant, it will not be 50:50 so it will not offer the same cooling (or in case of Alberta or Yukon, recommended freeze protection). Only flush if there are chunks in your coolant. If it comes out clean, do not flush. If you mixed with another type of coolant and you need to flush, try to figure out a way to blow out the coolant with a compressor (winterizing a trailer knowledge will help). If you flush with distilled water, you need to find concentrated coolant and not premix. Honda Canada only sells premix. If you insist on flushing, buy an extra jug or two of premix and flush with premix. Do not use distilled water. If you can find concentrate, find out your capacity (7.5L for my Odyssey EX), it is ok to flush like Jeff showed. This is what I do for my GM vehicles. After draining what water you can, add slightly more than half of capacity (3.8L or one gallon) of concentrate and then top up with distilled water. Note: If there is crud in your coolant, run with distilled water for a few hours, drain, refill with distilled, run for a few hours drain. Repeat if the water still had crud in it. Once the water has no more solids, then fill with coolant. All long life coolants meet the same cooling specs. what is different is the corrosion specs. The Japanese and Korean companies have similar formulas and specs. I suspect you could use any of the Asian formulas and would never have a problem. There might be a problem if you already have one type in your vehicle and add another. I suspect it will be minor. If your vehicle is under warranty. Do not change types because it might give dealership excuse to void your warranty (they will look at the colour - if you use aftermarket coolant make sure it is blue type 2). Why bother changing anyway? Price should be comparable. Honda Canada charges about $20 for a jug.
John Tischler, yes you are correct. To distill it you have to have to cover the pot and put a container inside the pot to collect the moisture once it turns to steam and condenses back to water. That way the minerals are left in the pot. Thank you for pointing out my mistake.
Thanks, Jeff. Do you think I could use your same method, in this video, to do a coolant flush on my daughter's 1998 Toyota Tacoma 2.7 liter four cylinder engine pickup?
@cgrscott, absolutely. This procedure is the same for any vehicle, with the exception of where the radiator and heater core drain plugs are located. You'll also want to take a look at your owners manual to find out how many liters/gallons of coolant your vehicle will need. Every vehicle is different.
@Real Lee, I don’t think so. I highly suggest getting a coolant funnel kit that is designed for bleeding air out of the cooling system. There is a link to one in my video description. I’ve used this kit many times with great success.
DIY Jeff, thanks for the video. Can you tell us about how much fluid came out when draining from the engine block drain? For my Honda Pilot, coolant capacity is 9.7 quarts (3.5 liter engine, same as the Odyssey I believe).
Where is the drain bolt for the engine block located? Facing the front of the vehicle would it be on the left side (passengers side) or the right side (drivers side)? And what part should I look for near it for reference?
john laughton, I don't have the vehicle anymore and filmed this over a year ago. I honestly don't remember, but at 4:46 into the video I show a diagram from the service manual that you can reference for identifying surrounding parts. The bolt is located on the back of the cylinder block and I'm guessing it's around the center of block as a point of reference.
I just checked my 2002 Odyssey, it is at passenger side and facing the rear of the car. Of course, remove the wheel first to reach it. As a reminder, open only the small brass part, not the stainless steel bolt.
How big is the hose via the drain hole? I have a hose that I use for brake fluid bleeding, can I use that is it around the same size? (Ford Focus) Also how do I know if burping is done right and there is no air in the system, the heater will be hot when I turn it on? Also car only got 20k miles, is it true no need to flush it if coolant got no contaminant?
Okaythen001 , I’m not sure what size the hose is. I happened to have it laying around. It doesn’t have to be a perfect fit. If it’s a little big that’s alright, you may just have to hold the hose if it is. Burping it is best done with the coolant fill attachment I have linked in the description. I didn’t have one at the time but it makes it super simple. Otherwise, leave the radiator cap off and run the engine for 5-10 minutes. The air should cycle up and out the top. If you only have 20k miles you shouldn’t need to flush. Just drain and fill. On m odyssey you flush every 50k miles.
Nice tutorial. However I'm a little concerned that this method doesn't leave things with the proper 50/50 mix of antifreeze/water. As you showed, Honda pre-dilutes their antifreeze to a 50/50 ratio. According to your estimates when you drain everything you can possibly drain you're only getting out 2/3rds of the antifreeze. When you do the flush with the distilled water and then drain that water back out you still have the system somewhat less than 1/3rd filled with water. Then you add the Honda antifreeze which is already diluted to the ideal 50/50 ratio. In that case what you wind up with is too much overall dilution within the system because your adding a 50/50 mix on top of a certain amount of existing distilled water.
ProductPicksAndPlans, I agree with your assessment. I followed the shop service manual for coolant replacement. The manual doesn't give any instructions about flushing the system, so if you just drain the 2/3rds and replace with the Honda 50/50 then the ratio would be correct. Unfortunately, Honda doesn't sell their coolant in concentrated form so there's no way to refill the system to the correct ratio unless you were to use Honda coolant instead of the distilled water to perform the flush, making a flush fairly expensive. Thank you for pointing this out. Where I live in Florida, it's not as big of an issue since we don't get cold temperatures, but I can see where other parts of the country this could be an issue. Any other vehicle besides a Honda, you could do the math and use more concentrated coolant over a 50/50 to bring the ratio back to the correct amount. The lower ratio hasn't caused overheating issues either. I've driven the van more than 20,000 since I performed the flush and it's worked flawlessly with no temperature regulation issues. (Just in case you were wondering).
I know it's been a while since this video came out, but they have third-party "Asian" compatible blue coolants that works for Honda, Acura, Nissan, etc. They are sold in both premixed 50/50 and 100% concentrate versions. So you could use the concentrate version if you need to increase the coolant-to-water ratio. Valvoline, Prestone, Peak, Napa and others are making compatible blue coolants for the Asian vehicles also. Just search "blue coolant" and check if it's 50/50 or concentrate.
Supertech would have been perfectly fine, especially on such an old car. There is really no point in using the OEM coolant unless you're still under warranty. Additionally, when you refilled with the Honda coolant which is already 50-50, you're ending up with a final result that is less than 50-50 due to the flush water remaining in the engine block. You should have flushed completely with water, then added Supertech concentrate to the system, filling exactly half the system's capacity. Then top off with water and you'll have a 50-50 final result.
There are two brands that produce concentrated coolants for Asian vehicles as far as I know. Peak OET and Recochem OEM coolants. The Peak version is available at Advance Auto and Autozone. The Recochem Version can be found at Bumper to Bumper and Autovalue stores.
@Rick Shafer, great question. Of course it's up to you, but each car manufacturer has different metal components within the radiator and the engine and all coolants have different chemicals that react differently to certain metals. Using the wrong coolant can actually cause corrosion.
My 2007 Odyssey looks completely different underneath. I've crawled all over from underneath and I can't find that damn drain plug. Most videos show a white, winged drain plug. You, apparently, have something different. But you never showed us what. The access holes under my front end are a lot different than yours.
@STBRetired1, Honda changed the design completely in 2005. My video is only applicable for 2002-2004. Here is a video I found that would work on your 2007. I have no connection with this guy, but his video is quick and to the point. Don't pull the entire plug like he did. Hold a wrench on the large nut and turn the small brass nut. Put a hose on the nipple first before you turn it. Hope this helps. ua-cam.com/video/ZG_q5xPFBmY/v-deo.html
Oh, you're talking about the coolant drain at the back of the engine. There are two drains - that one and one at the bottom of the radiator. But since I'm living in Central New York where it rains every day, I may be out of luck for the season. Maybe I should start finishing up putting my Harbor Freight trailer together and moving it out of the garage so I can put the car in the garage and finish the coolant draining job. Another problem is that at 80 I have a lot of desire but little energy.
Abdirahman A, ultimately the decision is up to you. Honda engines are rated to only except Honda coolant, but as you can tell from my video, the previous owner had put standard yellow coolant in it. If you don't have a warranty left on your vehicle then you could chance it, but if you have a warranty I would highly suggest Honda coolant. The difference is some of the additives are different between the two and Honda says using any coolant except theirs can potentially harm the cooling system. Hope that helps.
You should not mix coolants. If your Honda uses Blue type 2. It does not have to be made by Honda. There are non-Honda blue type 2 coolants that are identical. If you totally drain your cooling system, you could get away with any Japanese or Korean formula but why bother? Honda parts are designed to not corrode with the proper coolant.
Hi Jeff. I have to do my coolant in my 04 Odyssey soon so this was helpful. I do have one question. Did you get any air in the lines when you were adding in the new coolant? I didn't see you do anything to "burp" the system and I know air is common.
chris ryan , usually you only need to bleed air out of the system if you notice after running your vehicle hot, that your engine temperature gauge is above normal. This is caused by trapped air keeping the coolant from circulating. If this happens, run the engine at idle for 15-20 minutes with the radiator cap off. With the coolant de-pressurized the air pockets will cycle up and out. You’ll know if this is the case, when your coolant level drops after a few minutes. Hope this helps! Also, if you use the filling tool I mentioned in the video that I didn’t have, it will also cause the air pockets to release out during the filling process.
YoStu, not sure on that. The service manual doesn’t mention that method. It could work maybe, but I’m only guessing. It’s possible that no more would come out since it’s a pressurized system and it would need pressure to push it out of the heater core. Couldn’t hurt to try.
I recommend that you do not remove the radiator cap before you begin to drain. This way, it will drain much slower until you are sure you have yourself out of the way of spilling liquid and the drain pan in place. Then, remove the radiator cap. Use this method on any vehicle. You’re welcome! lol
DIY Jeff, Boiling Water does NOT make it Distilled. You just killed the germs and viruses..........So you won't have worry about your vehicle getting CV19 ;-}......... You need an actual Still (as in Distillery) to Distill water. Boiling Tap Water does NOT remove any the minerals and impurities in it. (It actually increases the concentration minerals & contaminants because the pure water is "boiled off" into the atmosphere - leaving same amount of minerals in less water. - You went backwards. No offense, but using straight Tap Water would have been better. Just buy the Distilled Water at the store next time.) The purpose of using Distilled Water is to prevent and keep mineral deposits from forming in your cooling system, especially the radiator. Mineral Deposits put stress on your cooling system by lowing the heat transfer, clogging passages and corroding parts.
Shiny Naj , following the procedures outlined in the video, if you don’t have rear AC then 5.8 quarts, with rear AC 7.9 quarts. Both of these amounts include the reservoir capacity of .6 quarts.
Alphie Gaspard, sorry, I'm not aware of any specific way to flush the rear heater core, but I would imagine that thoroughly flushing the system by running the rear heater with the same process I show for the front heater, would flush most of it.
Heating and Airconditioning Refgeration specialty. Simple disconnect your return heater hose and supply hose. Stick a hose in the return FLUSH for 10 minutes. Have a air compressor? Or a leaf blower? Blow the water out till you only feel air coming the supply. Duct tape the blower to the return to make a air tight seal if you don't have a air compressor. Buy 24 inches of heater hose and tape to the blower and the return. Have fun blowing the water out.
You should have turned the heater to hottest and blasting to flush the heater core. You used distilldd water and left 1/3 of it then added 50/50. This might cause freezing in really cold states because not all your fluid now is 50/50. Great video otherwise !!
Next time buy your self a funnel coolant kit. Do you you have a leaf blower? Do you have garden water hose? Do you have hill Driveway? Did you remove the T-stat? Did you remove the upper hose and the lower front the radiator? Next time flush with water stick the garden hose in the lower radiator hose and everything will blow through the upper radiator hose. Last used your leaf blower and in lower hose blow the water out. COOLANT KEEPS CHANGING BY THE CAMICALS MANUFACTURE PRESTONE MAKE A COOLANT FOR ALL MAKES MODELS. Coolant last for 10 YEARS. DON'T NEED to jack the car up. DO THIS FOR ALL INCLUDING THE RADIATOR STICK THE HOSE IN THE UPPER RADIATOR WITH PRESSURE CAP ON AND FLUSH TILL YOU SEE WATER COMING OUT LOWER RADIATOR HOSE CONNECTOR Keep flushing for 10 minutes. DO YOU HAVE AIR COMPRESSOR? Disconnect the heater hose the return and the supply flush with water and then you used a leaf blower or air compressor blow all the water out stick in the return and till no more water.
Flushing with garden hose puts mineral water in system. Bad. I use suction gun. Disconnect heater hose. Pump distilled both directions. Fill drive. Do again till system drains clear clean water. Prestone has 10 year 300,000 mile concentrate green compatible with any coolant 13 dollars a gallon at Walmart.
Thanks for the suggestion. The service manual describes that procedure under coolant replacement. A flush only involves draining the radiator and putting in distilled water like I showed in the video to flush out more of the coolant from the heater core. But draining the heater core is definitely a more complete service.
$25 per bottle for diluted Honda coolant? I can get it cheaper at the dealer believe it or not. Also no point in putting Honda fluid in there. Looks like somebody put something else in there. Green. I'd go with the aftermarket. Especially on older Honda's.
That's actually pretty good deal you're getting. My honda dealership is charging like $40 bucks for the diluted coolant. I just go to advance auto parts and pick up Peak OET Asian Blue for $20.
This is how clear instructional videos need to be. Thnks DIY JEFF
geproks , thanks for the kind words.
I believe you have it backwards in that the heat should be turned to max heat so to flush heater core. Turning the ac on could cause engine to overheat prematurely. I have 46 years experience as a mechanic. Don't forget to burp the system of air bubbles which can lead to overheating on Honda/Acura. Another reason the heat needs to be on max heat is to get air bubbles out of the system. Great video otherwise.

Anthony Melidy Spot on.
Its a major scam that honda doesn't sell 100% antifreeze that I dilute myself,water is super cheap compared to antifreeze!
Yes
Flush is 1000% better than drain and fill. Water is fine in fall spring, so water flush for 1-2 months is a win win.

Who you want the heater on so the water goes through and flushes the heater core

Hi Jeff. I have to do my coolant in my 04 Odyssey soon so this was helpful. I do have one question. Did you get any air in the lines when you were adding in the new coolant? I didn't see you do anything to "burp" the system and I know air is common.
chris ryan , usually you only need to bleed air out of the system if you notice after running your vehicle hot, that your engine temperature gauge is above normal. This is caused by trapped air keeping the coolant from circulating. If this happens, run the engine at idle for 15-20 minutes with the radiator cap off. With the coolant de-pressurized the air pockets will cycle up and out. You’ll know if this is the case, when your coolant level drops after a few minutes. Hope this helps! Also, if you use the filling tool I mentioned in the video that I didn’t have, it will also cause the air pockets to release out during the filling process.
Using degreaser on plastic can have negative effects. I have seen it firsthand with materials like lexan. It makes it brittle.
I thought was supposed to put it on high heat ?

Would lifting rear of the car bring coolant out from the heater core when draining first time?
YoStu, not sure on that. The service manual doesn’t mention that method. It could work maybe, but I’m only guessing. It’s possible that no more would come out since it’s a pressurized system and it would need pressure to push it out of the heater core. Couldn’t hurt to try.
I recommend that you do not remove the radiator cap before you begin to drain. This way, it will drain much slower until you are sure you have yourself out of the way of spilling liquid and the drain pan in place. Then, remove the radiator cap. Use this method on any vehicle. You’re welcome! lol
Great video 👍

DIY Jeff, Boiling Water does NOT make it Distilled. You just killed the germs and viruses..........So you won't have worry about your vehicle getting CV19 ;-}......... You need an actual Still (as in Distillery) to Distill water. Boiling Tap Water does NOT remove any the minerals and impurities in it. (It actually increases the concentration minerals & contaminants because the pure water is "boiled off" into the atmosphere - leaving same amount of minerals in less water. - You went backwards. No offense, but using straight Tap Water would have been better. Just buy the Distilled Water at the store next time.) The purpose of using Distilled Water is to prevent and keep mineral deposits from forming in your cooling system, especially the radiator. Mineral Deposits put stress on your cooling system by lowing the heat transfer, clogging passages and corroding parts.
How much coolant does it take?
Shiny Naj , following the procedures outlined in the video, if you don’t have rear AC then 5.8 quarts, with rear AC 7.9 quarts. Both of these amounts include the reservoir capacity of .6 quarts.
Check with your Local Honda dealers I bought mine only 20$ gallon cheaper than online
Jason Mai, thanks for the advice. I've heard that as well depending on the dealer.
how do you flash the rear heather core
Alphie Gaspard, sorry, I'm not aware of any specific way to flush the rear heater core, but I would imagine that thoroughly flushing the system by running the rear heater with the same process I show for the front heater, would flush most of it.
Heating and Airconditioning Refgeration specialty. Simple disconnect your return heater hose and supply hose. Stick a hose in the return FLUSH for 10 minutes. Have a air compressor? Or a leaf blower? Blow the water out till you only feel air coming the supply. Duct tape the blower to the return to make a air tight seal if you don't have a air compressor. Buy 24
inches of heater hose and tape to the blower and the return. Have fun blowing the water out.
😊
You should have turned the heater to hottest and blasting to flush the heater core. You used distilldd water and left 1/3 of it then added 50/50. This might cause freezing in really cold states because not all your fluid now is 50/50. Great video otherwise !!
Thanks for the tips!
Boiled water is not distilled water.
Temp should be turned to heat not cold
Next time buy your self a funnel coolant kit. Do you you have a leaf blower? Do you have garden water hose? Do you have hill Driveway? Did you remove the T-stat? Did you remove the upper hose and the lower front the radiator? Next time flush with water stick the garden hose in the lower radiator hose and everything will blow through the upper radiator hose. Last used your leaf blower and in lower hose blow the water out. COOLANT KEEPS CHANGING BY THE CAMICALS MANUFACTURE PRESTONE MAKE A COOLANT FOR ALL MAKES MODELS. Coolant last for 10 YEARS. DON'T NEED to jack the car up. DO THIS FOR ALL INCLUDING THE RADIATOR STICK THE HOSE IN THE UPPER RADIATOR WITH PRESSURE CAP ON AND FLUSH TILL YOU SEE WATER COMING OUT LOWER RADIATOR HOSE CONNECTOR Keep flushing for 10 minutes. DO YOU HAVE AIR COMPRESSOR? Disconnect the heater hose the return and the supply flush with water and then you used a leaf blower or air compressor blow all the water out stick in the return and till no more water.
Flushing with garden hose puts mineral water in system. Bad. I use suction gun. Disconnect heater hose. Pump distilled both directions. Fill drive. Do again till system drains clear clean water. Prestone has 10 year 300,000 mile concentrate green compatible with any coolant 13 dollars a gallon at Walmart.
@@arvbergstedt3303 Haynes manual I followed the instructions.
I guess you don't bleed the system of air. This is why I never take my cars to backyard mechanics.
Boiled water is not distilled
25 dollars a gallon???
Kenneth Mills , It’s deafly not cheap stuff. But if you don’t use genuine Honda coolant you can run the risk of corrosion inside the radiator.
Hi Jeff! You sound and look like Jeff...
Need to drain heater core by turn no heater
Thanks for the suggestion. The service manual describes that procedure under coolant replacement. A flush only involves draining the radiator and putting in distilled water like I showed in the video to flush out more of the coolant from the heater core. But draining the heater core is definitely a more complete service.
$25 per bottle for diluted Honda coolant? I can get it cheaper at the dealer believe it or not. Also no point in putting Honda fluid in there. Looks like somebody put something else in there. Green. I'd go with the aftermarket. Especially on older Honda's.
That's actually pretty good deal you're getting. My honda dealership is charging like $40 bucks for the diluted coolant. I just go to advance auto parts and pick up Peak OET Asian Blue for $20.

Good lord! You dropped the car down on the jack stands so fast, it nearly fell off!
