Overheating Boxster
 

Hi all

I wonder if someone can help me, i have just replaced a radiator to a 986 on Friday, no problems there. I took the car up to Leeds on Saturday also no problem. I checked the coolant level up there an toped it up but this is where the problem lies i forgot to screw the coolant cap down. She run fine until we hit an accident queue where she overheated, went up to about 96deg, we pulled into services topped the water up and carried on (with the cap screwed down this time) we started to overheat again and again we stopped when the temp went to about 90 deg. I did notice that the heaters started to go hot and cold,. We called the AA and got taken back on a pick up. I started the car the next day there is no there does not seem to be any oil in the header or water on the dip stick but the level of the water kept going up and down, question is this a thermostat problem, water pump problem or gasket problem.Thanks

It could be an air pocket in the cooling system, there is a discreet method of "burping" the system, I think lil B posted it once, a search should give you the method to try, good luck.

Air in the system. Pull the bleeder valve and drive for a day, then top up as needed.

Thanks guys for the info, just one other thing where would i find the bleed valve?? and how easy is it to get to?

Read this thread. Should help out. The bleeder valve is located below the oil and coolant cap (under the black lid)...

Thanks guys problem solved!!!!!

Good... now tell us how?

Exactly how you said by pulling up the bleed valve and let the engine run until no more air was trapped.

Thanks
