Help Please-2002 986 Overheating

[daviddelpauley]

Hello everyone!

I’ve been having overheating issues with my 986 2.7l five speed base ever since I started repairing it from hitting a huge pothole.

Initially, I busted my passenger side radiator and ordered an aftermarket one from ********************************. While swapping my busted radiator out for a new one, my mechanic cracked the metal pipe belonging to my passenger side condenser, but was told I could drive it like that in the meantime but I just would not have A/C since all my freeon released once the damage was done to the condenser. Will this actually cause my overheating issue?

I have also considered the fact that it might need to be bled out for airpockets since a brand new radiator was installed, but want more opinions and ideas.

Once the temperature hits around the 250° mark you can pop the trunk and feel heat, as well as see droplets of coolant right around the coolant cap where it appears to be abnormally pressurized. It appears I’m losing coolant as well and need to top it off every time, however I cannot find a leak anywhere. I haven’t lifted up the trunk carpeting yet to check the reservoir for cracks or leaks, but I am willing to bet that is not where my issue lies regardless, but will check tomorrow anyway.

Thanks in advance for any help or ideas.

The AC condenser is not your problem with overheating as no coolant runs through it.

Since you replaced your radiator, you absolutely must bleed the air out of your cooling system. The best thing to do would be to take it to an Indy and have them drain and fill your system using an air vue system.

The other thing you can due is pull up the bleeder valve in the trunk and drive your car (monitoring temps) for a few days to burp the air out. Need to keep an eye on coolant levels after a drive when car has cooled off.

Dghii is right, you should Not drive your car after allowing air into the cooling system, an overheated engine is very expensive to properly repair..

Another vote... the bleed procedure is rather tedious without a vacuum system of some sort. It is well outlined in the Bentley service manual. It is a 100% requirement to do after any coolant system (loss of fluid) work.

I open up the burp valve and drive around my neighborhood for a few laps. When I fill it up I do it on an incline, my driveway. I had one of those fancy devices to bleed the system was a PITA I sold it. I have a 99 and burping it works fine.
