Best way to diagnose if your head gasket is bad

[@gottfriedj1647]

I bought my first car with a blown head gasket. At the time it had obvious signs but I didn't know what it was. You expect better things from a human being. My second car also had a blown head gasket, it was a dealer NJ who hid all possible signs but using sealant I guess. Signs started to appear weeks after the purchase. They were not obvious, first a CEL, then hesitating at cold start. What a nightmare with that car. Honestly, I didn’t know until now what it was like to have a car that doesn’t need coolant every time you drive it. I was constantly checking my 3rd car as I almost have a trauma. THE ONLY WAY TO TEST IT RIGHT is by doing a cylinder compression test. No chemical test on the radiator, no pressurizing the cooling system, forget it. It's like a sickness with different symptoms or no symptoms at all. Thank God my 3rd car is fine. Now, I just bought a Corolla with 90K miles and I’m freaking out as the coolant level went down a bit. (3 years later, story revisited) my Corolla is alright. 20K miles strong. It only loses 1” of coolant every 6 months, same as when I bought it. My prayers were heard. Thanks for comments.

[@clearsailing7993]

You can also use a leak down tester to check your valves. Make sure the piston is at top dead center on the compression stroke. Apply pressure to cylinder. Listen for air at the intake and at the exhaust pipe.

[@richardpope9985]

Use some Blue Devil Head Gasket repair. It worked for me. Has been holding for about 1 year now. I had white smoke out the tail pipe. Used the Block Test Blue fluid and it confirmed hydrocarbons in the coolant passage way, because it turned yellow. After I used the Blue Devil Flush and gasket, and followed the directions exactly. It sealed the head gasket good. No more white smoke and blue fluid stayed blue. Worth a try.

I bought a leak down tester yesterday, and I saw your video today. I'm going to test our 2001 Buick next. On the 3.1 Liter GM engine, the intake manifold gaskets can leak and coolant gets sucked into the manifold. So, I'll see how it goes.

Steel seal, that you add to the radiator, has silicate in it to stop the leak. The high heat by the heat gasket makes it turn hard.

@clearsailing7993 that will block water passages. It won't fix a head gasket. The only time I have seen a hg leak taken care of, if it was leaking externally and stop leak plugged the hole.

@@subtledriver Hiiii! Thanks for responding! This is nowhere near a realm that I am even slightly familiar with. He had an oil change prior to driving 90 minutes to his overnight college orientation. When he arrived he noticed it was really hot in the car when he parked & finally noticed the coolant warning level light was on on his dashboard. He didnt use the car for the 2 days on campus. I told him when he left he needed to go to the closest auto store & buy coolant. The store employee helped him and added it to the coolant reservoir. I was hoping that was the issue. The warning light turned off and he started the 90 minute drive home. Naturally, the light came back on while he was on the interstate. Someone recommended he turn the heat on high & defrost & drive with all the windows down. He did & got the car back to our house. A friend suggested we have the thermostat replaced. We had it towed to a mom & pop shop. The gentleman said he ran the car & notice the coolant level dropped by there wasnt any coolant on the ground, so it was going into the engine. The car is a total loss. He asked me to get it off his property that same day. So $300 in towing costs (to & from) but it came back home. My sister, who lives 8 states away, suggested we buy the head gasket combustion leak test kit. It came yesterday and while I had the car heating up I noticed coolant WAS leaking from the bottom front bumper on the driver’s side. I did the test via the coolant tank and was thrilled when it didnt turn green or yellow. The liquid remained blue. I turned the car off for it to cool down and thought Id try again later on the radiator. I took the cap off and didnt see any coolant in the neck. I let it run for 10/15-ish minutes and then noticed the coolant was coming up the neck, like in your video but there werent any bubbles. I turned the car off and a wee bit of coolant did overflow from the neck. Then I started researching again and came across your video and was crushed hearing the diagnosis via your test results.

[@dragforlife8660]

So if the coolant goes to the reserve bottle all the time and the radiator goes dry it means or is a sign of a bad head gasket too ?

[@genxiong2695]

No. The reserve tank is there for overflow and it's normal. If your radiator go dry it's probably leaking somewhere. Signs of bad gasket will be boiling coolant in the reserve tank. But that's not always the case. Could be air leak in the system and/or bad radiator cap, water pump, etc..

That's exactly what's happening to mine I got a engine 75k and its doing this

[@rmr1300]

Very informative, replaced my radiator and fan(with cheap parts not OEM) due to a collision. Radiator began to start leaking, eventually severely. Added stop leak into the radiator no longer leaking but now my car is over heating. A day later I realize the fan isn't working. I'm getting the overflow of coolant from the radiator neck when the car is on, also notice what sounds and feels like boiling in the top hose and radiator cap. I was thinking the stop leak may have clogged the radiator. Can the fan not working cause the overheating, overflow of coolant, and boiling sound?

[@sterrshow5016]

A boiling sound is likely from air trapped in the system, especially if you hear gurgling when switching on the heat. My guess is your cooling fan has a problem if its not on constantly when the engine is up to operating temeperature, have you felt your radiator hoses? Are they hot to the touch when the car runs for a while? If not maybe your water pump broke or your thermostat is stuck shut cause the coolant to not circulate.

stop leak will clog your radiator and put you in a world of hurt.....dont use it!

Why do mechanics fear head gaskets? They are not that hard to change if you have a shop.

[@automachinehead]

bc advanced damage to hg can cause cylinder heads to crack and once there is a crack every other component in the combustion chamber needs to be checked prior to fixing

Nice tuitorial, I love 💕💕 you it. How do I get that tool you used in testing the head gasket, am a mechanic and I need that tools. Good job!

Hello I have aHino dutro everything is okay no leakage but when it’s loaded the temperature is going high

[@jerrylisby5376]

Does head gasket stop leak work? My coolant looks reddish.

[@lucidalist7078]

Great video, I never seen a test done like that. Just a suggestion. I have done this many times my self. If you detect a leak like that in its early stage a simple retorque on the head to manufacturer specs can fix the problem. We use to do that all the time with cast-iron engines. With todays alloy engines I have found this trick only works if the leak has just started. I have tried it on engines with bigger leaks but it has only worked with small leaks.

[@Zach-k2p]

That’s a bandaid always was even with the old iron motors. You must be in the used car sale business those are the only scambags still using that “fix”

I have a 2003 Honda Accord 2.4 ltre i let it warm up for 22 minutes the morning was cold suddenly my gage went on the H section radiator was overheating and i had to shut off the car a little bit of smoke was coming out of the radiator and i just had put a brand new thermostat and thermostat housing . What do you think it is causing this problem ? Also my car has 247,000 miles.

[@LilyWillow22]

Check to see if there’s coolant on your spark plugs…

[@mikem5475]

Awesome video, makes good sense and right to the point

[@doc-holiday]

Great video another helpful tool in the arsenal to blown head gaskets. Having said i would also suggest if your in dire straight you could also try to use Risolone block stop. Its a very good product and has helped me out with a friends Toyota Corrolla with a similar issue to this video.

I got a 1998 Ford explorer what does it mean when I have oil in my radiator?

[@ram43x80]

How much would it cost?

[@elvismartinez9642]

How can I get the tool ?

[@gorgegutierrez9704]

So you dont have to have water in oil to have a blown head gasket?

[@S.khan.123]

My coolant flow out from reservoir cap huge amount.what to do

[@glyshorts9107]

Same test work for a duramax?

[@82_KID]

It will also do this if it is just low on coolant .

Thank you for this easy and quick way of knowing for sure! Gonna do it today..

Honda told me cylinder #3 is leaking coolant and may have block damage would a new head gasket fix this?

[@JK-cq5nc]

Hello, I've a 2005 ford explorer v6. It has oil in the coolant reservoir. It has a transmission cooler that is not connected to the coolant, it has no engine oil cooler. So the only thing i can think about is a bad head gasket? Btw 2 head leak detection tests that i did were negative (is a false negative possible?). The engine was rebuild and was put in 1k miles ago, however the store employee forgot to tigthen the clamb on the bottom of the radiator and i was at least 2-3 quarts low on coolant, can that have done the damage?

[@flywiseman]

I recently bought a 1980 cj with a 258. I can't keep it from getting hot. The radiator hoses get hard as well, this is probably at a minimum a head gasket problem right? Or could be rings as well? Thank you for the video

[@marionpua8002]

Ive some question, I did a drain and fill of coolant on my 2020 hyundai accent , drain the radiator and reservoir and fill it back in and put the cap back on, and i started the car with ac in full blast, then i took a bath maybe 15mins then when i get back to the the car the temp gauge is flashing red, i quickly turn the car off, waited 2 mins then i opened the radiator cap and filled in about just a glass of coolant and its already full, then i started the car again , in less than a minute the temp gauge went back to normal, drove it around and rev it and everything is back to normal, the question i had in mind is did i make any serious engine damage from the overheat like head gasket?
