Recently replaced the whole cooling system (radiator, hoses, water pump, thermostat + housing) after a burst hose on my '99 led to an overheat. It was all OG so put all new system in and flushed. The Jeep is running perfectly, oil looks good and the (green) coolant looks nice and clean but I am worried about whether the overheat damaged the head gasket.
I bought a testing contraption (see below) and installed the rubber plug to test for combustion gasses. I had driven the jeep around the block first - literally not more than 3 or 4 minutes and I noticed a bit of pressure release when I opened the radiator cap. Radiator was already warm - more than I would have expected for a short cycle. As soon as I started the motor the coolant filled the little gadget and started coming out the top. No clue what colour it was turning since it all blew out the top and got replaced with coolant!
That's not right, is it? I know its supposed to have some pressure but it definitely feels like something is pressurizing the coolant system far beyond what is normal. No sign of anything amiss in the oil and no trace of any vapours out the back or loss of coolant.
I bought a spare MLS head gasket set from EngineTech but was kind of hoping I didn't need to install it... Is it cactus guys?
