The directions say Blue Devil flush can be left in the system with distilled water, and driven normally for several days to get more dirt, etc. loose. Then drain the radiator and replace with 50/50 antifreeze. (If you're using water, the outside temperature can never fall below 32 degrees )
@@corymauch779 There’s two different versions. The stronger version says no longer than 4 hours. The basic one, which I believe this UA-cam used, says you can drive it around 3-6 hours intermittently over the course of a few days.
My proffesors always told me to use strictly distilled water instead of foucet or water hose, city water etc. And also to never use pure water. Due to minerals in them .thats why they rust up and water pumps fail and rust up. With distilled water you'd be rust free forever in your cooling system.
@@2carpros Watched the video, went to the comments because I KNEW someone would call out the hose water. I respect your answer though. I have an 08' RAM that I do all the wrenching on myself and has almost 200,000 miles on it. Driving around CA i see way older vics with people driving them that I know don't do regular maintenance and they're driving fine, so having some hose water temporarily flowing in the cooling system... no big deal
Hi im about to start the head gasket sealer project!! Gona do the radiator flush first!.. Should i do my oil change after the flush just before i add the sealer?? Or should i change oil first thing?? Oil is milky btw
Hi. I've got oil mixed in with my coolant and it's gotten to a peanut buttery-like texture. How difficult would you say that would be to clean out? It's a 2016 dodge dart and as far as I can tell, I don't have a radiator cap so I'd have to do it all through the overflow tank. I've been looking it up and I've seen videos saying I could flush it with dishwasher detergent. Would you recommend that?
Having oil mixed with coolant means you've got much bigger problems than just contamination. What you're looking at is evidence of a blown head gasket, cracked cylinder head, cracked engine block, a leaking oil line or some combination of two or all of these. Bottom line, get it checked out by a mechanic.
@@techsolutions123 probably the automatic transmission cooler part of the radiator, some cars have the radiator cool both the engine and automatic transmission, if the seals/radiator fails near the automatic transmission fluid lines in the radiator, sometimes the coolant and transmission fluid mix. You would need to replace the radiator and change the coolant and transmission fluid to fix that problem.
I know when flushing you use water what about sealer Does it matter if you use sealer with 50/50 coolant or is plan water recommended and then add concentrated coolant ?
🙂 When I take off, one of those spring loaded hose clamps, I replace it with the standard hose clamps that take a 5/16 socket. 👍 Just sayn' 😏 . I hate those spring loaded clamps. 🙄. There the kind of things, that are why I don't work on cars for a living. Engineers!! 👎. 😤
As long as you keep on top of tightening them every so often! The spring ones are good because the keep contracting as the rubber ages and squishes out. Thanks for watching!
Not really. There are plenty of people that will scream and cry and insist that you need distilled but I have used hose for flushing and it is just fine. Thanks for watching!
Hi. Thank you. So is it nessasary to take the thermostat out before flushing the system with the product ? My radiator fluid is brown and rusty. The guy I bought the truck from is saying it’s the thermostat that’s rusted. I ordered the new thermostat, but can I flush the system with the blue devil flush so long and keep it in the system for a week or so ?
I put blue devil radiator flush oil degreaser in at night drive around a little bit and figured I'll let it sit and I will empty it in morning I go outside 1st thing in morning and all the water is all over the floor I didn't have a leak to begin with do you think the flush ate up my radiator or something
The blue devil radiator flush oil degreaser is stronger than the regular bluedevil radiator flush. Follow the instructions on the bottle. I'm going to use the BD radiator flush for the first time next week.
Yep, that's what I thought, too, at first. I bought a 2001 Windstar in 2009 with 68K miles and a flush was one of the first things I did to it. I thought that someone had previously busted off the head of the petcock, ( it looks identical to the one you were working on) . Until then, I was used to the plastic 5/8" bolt head (and before that, the brass wing-nut type from the 60's and 70's). I couldn't see in it at all and thought that I would have to go the lower hose removal route. But I did pull out an inspection mirror to check for damage and it turned out that it took an 8mm Allen (I checked again today because I couldn't remember the size the other night). The Allen wrench is a really tight fit and sort of a pain, especially once the hot coolant starts coming out. My wife's Navigator and my parents Taurus also have the 8mm petcock. I guess yours could have been a broken off stud, though. I just flashed back to when I thought the same thing. Thanks for the video. I was curious about the Blue Devil Flush and came here from a search. Take care!
My ac works but not my heater. What do u think is wrong it's just cold air blowing out the heater but like I said I recently got the blower replaced so I would think that would have something to do w the heater not working but I'm not sure

It doesn’t say that. It says not to leave it in for more than 4 hours.

If there’s no radiator cap do I fill the hose water in the upper coolant hose ?

Since its been a year, I'll save the advice. You got it figured by now.

I just used 50/50 but you could use concentrate as long as you added equal parts water. Thanks for watching!
Why do you need to remove the thermostat??
so that the water free flows through the entire system without requiring certain temps for the tstat to open flow
Can this be added to coolant vs water then flushed ??
Best to remove the coolant and flush with distilled water before using
I have a trailblazer. You can't take out the thermostat. It's built in to the housing
You should be able to take it out still, it might just be tricky. Thanks for watching!

They are used because they expand and contract, a worm clamp does not.

I used plane hose water and corrosion was increased, I would only use distilled water
