How To Find Any Leak From Your Cooling System
Вставка
- Опубліковано 10 лют 2025
- In this video I'll show you how you can test your engines cooling system after repairing a leak or replacing a faulty component like a water pump, radiator or coolant hoses. You need to do this test everytime you open the system for repairs to make sure your repair was successful and also there are no other problems in the system before you add coolant into the system.

After fixing the first leak, not only is it good to check for other leaks that might be present already , but fixing the first leak will cause the system to achieve a higher pressure, which can cause some other weak spot to leak anew.
It’s always so much fun to just f around and waste 100$ in coolant because you are a dodo brain and you didn’t do what you said. Check every single freaking clamp as well
I think that's my issue new rad new ac condensor new thermostat pump belt I done it all now found small leak .can't locate my dye and torch ggrr . So may new new 1 . Can then check while running ideally in dark
Please continue on with this car. Very interesting to see. I pressurized my 1994 Grand Am 3.1V6 and it looked good. So I replaced the expansion tank cap (there is no radiator cap on this car) and all seemed good for a few months. Now I've noticed something has leaked on the front side of the engine. I had replaced the water pump last year. I guess I'm going to have to investigate further. Thanks for another informative video. Cheers
make sure you check those intake gaskets as well very bad on the gm 3.1...
@@turboimport95 Indeed they are.
Off topic but you are looking in much better shape than years past is there anything you are eating or not eating? Thanks.
I'm eating less especially processed sugars and working hard :) have lost about 40lbs compared to a year or so ago. cheers
That’s wonderful congratulations. What a miserable place to get into. People complain when they have what seems like a simple job expand into something way more expensive and this is a great example of why that is always the case. The engineers that build these things should have to work on them, then they all be set up like the Nissan 1600 was. Back when it was Datsun. A real joy to work on if there is such a thing. Great video
Its the avocados he’s growing an avocado a day helps to lose weight and has good fatty acids the body needs.
Great video. Keep' em coming please.
I thought the same thing: he is looking much healthier! I thought it was all the manual-labor from the garage-foundation . 😂
Great to see you back I hope this trend continues I've been a member since day one
Always love to see any kind of Honda content. I am a huge fan of Honda and like to see work done on the engines I don’t see every day.
That sure makes things easier, as long as you can find the right radiator cap adapter 😄💕👍
Great to see you back in action! 😎
More to come!
Been a long time for a diy like this. Very good and thanks!
Glad you liked it!
Great job! I actually kept up with you and understood everything!
Great to hear!
This is one of the specialty tools I use the most, since cooling system problems are surprisingly common in engines. The only thing is, you never seem to have the right adapter. For example my Astro kit didn't have the right adapter for old model Chev trucks, so eventually I got another kit with more adapters. The backbone of the Astro kit is better quality but the chinese knockoff gives more diversity of cap options.
Amazing coincidence!! Just now I came back to the house and smelled coolant and I want to find where the leak is coming from😁👍
Nice
How Much Does Coolant Leak Repair Cost in USA for Any type of Vehicle?
😳 I swear you are in front of a green screen or the display on my phone is just that good.😆
Speaking of Astro, that air powered air tool is the way to go. So much easier. Note, the adapters say they work with most kits. Not the MityVac 4530. Had to get a used Astro kit.

Couldn't be any better timing on your video!!!!
Thank you very much, I'm looking forward to work on my 97 accord.
Excellent videos.
I figured out how to make a jerry rig version of this. Take a old radiator cap, drill a hole big enough to install tire shraider valve and use a bike pump with a gauge 🤣 genious
A pressure tester works wonders. On my pt cruiser and it was full of water yeah and i was messing with a lower hose i forgot why and i didn't put the clamp on good because i was irritated with it and wanted to be done right lol. Not even like 4 psi blew the hose right off along with muh coolant (didn't have distilled water at the time) so i never started the car to test it that way at all and could have saved my engine and a stranded tow possibly back home to see my shame of not putting the hose on right or with the clamp on tight. Pressure test your systems no only good for finding leaks also good that you didn't mess up on a installation like i did.
haha yes it's a great way to check your work too.
Another excellent automotive repair video.i like the looks of you're new shop.👍🏻👌🇺🇲
Glad you like it
Think you so much this is just what I’m dealing with
Another nice video! 👏👏👏Waiting for the rest 👍
I finally found my leak thanks to u. Excellent.
Woah nice Honda selection is that a white prelude and black del sol in the back
Can you PLEASE 🙏🏼🙏🏼 do a video on boiling coolant in your overflow reservoir? Like ALL the PRIOR things that it could be? Like BEFORE you confirm it's a head gasket 😞 Like how to for sure test the thermostat to see if it's the cause and hopefully replace cap and the thermostat so it hopefully fixes it🤷🏼♀️🙏🏼
Preludes are awesome 🙂
Valve lash adjustment as well perhaps? seeing as it has 200k. You may have shipped this one already, but it'd make a good video, seems like Hondas always have valve noise.
Thats a good one, however this one runs pretty smooth.
Ooh a 4th and 5th gen in the garage! Nice!
Would love to see you do the water pump in that prelude . I have a 98 .
will do.
Do you think putting a uv dye in the water and use a uv light to see where it's coming from better
I was wondering why you hadn't mentioned the UV dye, then you did.
Subscriber here. Upper rad hose leaking for rad connection. Only when cold? Engine warms up, it stops. Clamp was loose. Tightened it quite a bit. Still leaking some. Any suggestions?
Thanks 🙏
Welcome
Thanks josh

Would like to know if you have or will be doing a video on replacing electronic parking brakes.
I don't have one planned as of right now.
No I would love to see how to do a twin cam timing belt and water pump job please make it your next video Tom from New Jersey♡♡♡♡
Ok will do
love you. love your videos
I have to fill reservoir every week or 2 ..pressure tested when car was warm to touch and saw water driping from on that side of engine but couldn't see where it was coming from i release the pressure and presurise it again but there was no leak anymore thats an strage thing so wonder what could it be it had coolant still
I have my '96 Toyota Corolla in the shop. Water pump went bad then right after my head gasket blew. Might as well do my timing belt while the mechanic is doing the water pump. $$$
Hey hey hey how's it goin do it yourselfers 👋🙋♂️👍
:)
Youre the best
Hello! We would like to license one of your videos for use in our feature film. How can I get in touch with you directly to discuss this? Thank you!
CAUTION TO ANYONE REPLACING GEAR DRIVEN WATER PUMP! It is very important to make sure your vehicle engine is or is not a non-tolerable or tolerable engine. You may have to use a tool to hold your timing gears in place. First set at top dead center and set timing gear holder in place. IF ONE WAS TO REMOVE THE TIMING BELT ON A ZERO TOLERANCE ENGINE. THE ENGINE VALVES WILL STRIKE THE PISTONS THEREFORE CAUSING CATASTROPHIC ENGINE FAILURE DUE TO BENDING OF VALVES AND DAMAGE TO PISTONS. "PLEASE DO YOUR NEW DEALINGS AND LOOK INTO HOW TO REPLACING YOUR WATER PUMP" IF YOU DO NOT FEEL COMFORTABLE PLEASE TAKE VEHICLE TO A QUALIFIED REPAIR SHOP! REMEMBER REPLACING A WATER PUMP THAT IS DRIVEN BY TIMING BELT CAN LEAD TO CATASTROPHIC ENGINE FAILURE. PLEASE BE VERY CAREFUL.
Doesn't pulling a vacuum and it holds a vacuum verify there's no leaks?
Could you have just looked at the seep hole?
It wouldn't leak without pressure in the system, you don't want to miss it and put coolant back in.
I always say PVC valve before correcting myself
why distilled water?
to prevent mineral deposit buildup in the cooling system.
Perfect Hair 🙂
That water pump looks like torture to replace
You get it from the bottom, its a bit of a pain
Great video thanks for sharing.
Thanks for watching!
I like ur language
He lives
Waste of money. I use a brake bleed kit.
Deflate nearestbtyre to around 17psi. Attach the hose to the tyre other end screw onto expansion bottle as a lid and it does exactly the same thing at a fraction of the cost. I think mine was £8 from Halfords many years ago. 🎉
Dude. Show me some avocadoes!
haha I'll get you a shot next time.
what about a leak from that POOOOOSSS
You are god-fixing
Omg one small water leak equals replacing so many other things. $$$. What does a mechanic charge per hour in 2025?
You lost some weight!
Hello I would like you to just give me a car since mine burned 🔥 up in flames. I would like to Use my white privileges please. Look forward to hearing from you.....good day.
Nice work carnal! When are you gonna do a meet and greet? We would love to check out the new shop maybe do some collaboration. So cal mechanics rifa
