I have done a lot of research and there are a ton of overheating threads on here but not many of them follow up with a solution .
Today I put my car on the dyno at a car show to do a few pulls and everything went smooth . I took the car home after and let it sit for 3 or 4 hours and then decided to go for a cruise .
I did a couple short pulls on the highway then went back to cruising speed and eased down on the gas and boom , coolant shot up on my windshield so I pulled over , opened the hood and there was coolant everywhere , but it just appeared to have leaked from the cap on the tank. I have a moroso reservoir with the factory cap . I let the car cool down and topped up the reservoir with some bottled water I had just bought at the gas station and drove to a nearby parking lot .
I let the car idle for a bit and it started to over heat again .I shut it down and burped the system once more using the reservoir cap (my crossover nut is rounded off) then let the car cool down again and drove it home and parked it .The car didn't overheat on the way home as it was mostly all highway driving .
Its weird how it did this all of the sudden . The dyno did not have a fan blowing into the heat exchanger and I had mentioned that it was a concern , but I figured 2 pulls wouldn't hurt . Could the car have overheated on the dyno slightly and air locked? There is no coolant in the oil that I can see , and everything looks fine . On a side note , my car did start making a small ticking noise around the passenger side head a couple weeks ago . I just chalked it up as a small exhaust leak and wasn't to concerned about it . I hope its not a head gasket or something to do with the head .
I am going to try and burp the system again but using the crossover fill tube this time . I just have to find a way to get it out . I am also considering changing the thermostat to see if that helps . Any ideas on what else it could be ? The car has a fresh aluminator with original heads and never had overheating issues prior to today . I always prepare for the worst but was just wondering if anyone else had similar issues and how they resolved them . Any information is appreciated .
