I have a question. I have an Infiniti G 35 coupe that when I start up in the morning when it’s cold or any temperature pressure builds up in the radiator hoses right away like seconds , but it’s not a head gasket. The car does not overheat the reservoir never gets above max. The OBD2 reads normal in between 185 and 210 depending on the weather, both fans are operating at the proper temperatures, the heater works great in the winter But after driving for a half an hour or so normal driving, the engine is just scorching hot. I don’t know if that’s how these cars just get but you cannot touch anything on the motor yet. It only reads 180 to 210° do I have a plugged up radiator when I put a spill free funnel in it fluid fills it halfway up and then it stays that way throughout the whole temperature range. There are no air bubbles even when I squeeze the hoses. and of course you can’t see if the radiator is flowing Because of the spill free funnel, and there’s no way to run the vehicle with the radiator cap off without the funnel freeze just pushes out. Is this normal?

If there is only a minor exhaust leak into coolant, will a lower rated psi (e.g. 15 psi instead of 21 psi) coolant expansion tank cap be used? I have come across an engine that rises pressure near the cap limit shortly after shutting off. And in many cases after hot restarting the engine (e.g. 5 min after refueling) the engine jerks as coolant seeps into the cylinder and fouls one of the spark plugs. I believe this can work, especially if 50-50 coolant is used. There is no need to have 21 psi cap, it is just overkill.

A leaking head gasket can cause to much pressure Easy to diagnose take cap off start the car let it get hott there is a tester looks like a big syringe with no needle lol has yellowish die in it u put in big syringe put it on where radiator goes if it turns color u got a head gasket leak easy enough the tester is cheap get it anywhere it’s called a combustion leak detector

Thanks for the video. I have an issue that is stumping me. Volvo xc 70 5 cy. Tested for head gasket and the Co2 tester did not change color, which tells me on exhaust in coolant. But the water level in the reservoir (there is no radiator cap), fluctuates and pumps water and air out. It acts like the motor is overheating but the temp gauge reads within the normal range. If i drive it much, it will overheat. There is a radiator leak and a new one is ordered - i repaired this one with plastic epoxy, and it's almost stopped. Thermostat was removed for the test. i have two radiator caps, and it acts the same with either one. Is there anything else that would cause this geyser effect in the cooling system??? Thanks

My car wouldn't start this morning, well it started for 3 seconds and stumbled before dying then not starting. I took the radiator cap off and it had a lot of pressure and blew coolant on me (it was cold btw). I then pulled plugs to see if they were white and they looked fine. I started the car with the radiator cap off and it started no problem, it slowly pushed out a bit of coolant along with some bubbles then it stopped and didn't push any more out and no more bubbles. I'm hoping it's not a headgasket. The car doesn't have white smoke out the exhaust and plugs look fine. I previously had an issue with the radiator cap but I don't think that would cause it to build pressure in the system while cool would it? Strange.

@@OkieDokedU Unfortunately it ended up being the headgasket was blown on cylinder #4 and was pushing exhaust gas into the cooling system, luckily none went into the oil. Strange thing was I did a compression test and it came out perfect, all cylinders were within 3PSI of each other yet the headgasket was bad, but after thinking about it, a cylinder has way way more pressure when running and combusting than just moving up and down so it makes sense I guess. Anyway, I had the engine rebuilt so it's all good now.

I need help. I change my cylinder head it was blowed (mechanical told me cylinders are not very good, he see that antifriz has go there when my head blow). But now with new cylinder head i have problem with my antifriz level. When i will off engine after drive, there is normal level of antifriz. It is always after maximum line. But in meanwhile antifriz level is going down under the minimum line, and when i start engine there is sign to check coolant. Before i open cap there is missing antifriz (under minimum line), but when i open cap there is little pressure and antifriz is coming to normal line between min and max line. I dont have white smoke, i dont have bubbles in coolant. I have 2.0 TDI BKD 2005
