Boxster Started Overheating at 40° - Help!

[rick3000]

I was concerned, because I have never seen it go up so high, but if it is normal, I'll just clean my radiators this weekend, and see what happens.
Thanks everyone!

Rick, IMHO, cleaning them correctly means pulling the front cover off, headlights, side markers and some misc hardware is part of the disassembly. An easy task the second or third time but be careful the first time. You have to pull the fender liners, there are reusable plastic fasteners that you need to be delicate with. It also helps to have a friend around to help with the bulky bumper cover, however if you're careful one guy can do it. Once inside you will see that the radiators reside in a sealed chamber so any dirt cannot escape, if you have the Bently book it has excellent instructions and pics, if you need any help from me just PM, I've been inside mine a few times tweaking the spoiler lip and playing with radiator screens...

Rick, if you don't want to pull off the front bumper, you can try doing some cleaning of the radiators by doing it with the leaf blower. Blow out as much as you can when everything is dry. Then wash everything down, and blow them out again.

With all due respect, a vacuum makes more sense although it will never get the packed debris. The radiators are sealed in a closed, briefcase like pocket, a blower wont help at all and may even drive more dirt into the sensitive fins, no dis to B mussanti at all intended..peace boys good luck with the project..

Thanks for the advice. I have the Bentley manual to guide me. I am going to try using a leaf blower and see if still heats up so much, then I may opt to remove the bumper. I've read about doing it, and I don't have to much else to do this weekend.
Just as long as running the engine above 180, isn't going to hurt anything.

Two things, have your mechanic test the fan resistor, it may have blown casing your fans to not come on which could account for the slight temp increase. Second, if your not going to do a full disassembly to clean out the radiators (see below) then don't bother with the blower as mentioned above. It will do nothing except, well, blow a bunch of air.

Check out this previous thread on cleaning out the radiators:
How much dirt could really be in there?

a lot of debris can collect in there:

you're getting good advice; check the fans, burp the coolant reservoir, pull the bumper & clean the radiators. the car's normal temp in hot weather is what you show in your pic. that may be a little high for 40° days, but nothing that will damage your car.

as for being concerned w/ running it up to 6k RPM's? dude, it's a PORSCHE. it's designed to be driven hard. they even stay nice and cool on the race track. don't worry about putting your foot in it now and then.
