A fellow 968er is having cooling issues with his 968. Any opinions would be greatly appreciated. Jeff
I bought my 968 in 2000 then had to replace the thermostat because the car was indicating it was overheating when it wasn’t. This spring, the cooling fan kept running (all night) after turning off the car and it was killing the battery. Again, replaced the thermostat. This week the car again indicated overheating and actually cut off I guess automatically when the gauge went into the red. The car wasn’t actually overheated. Had towed to the mechanic and he is again replacing the thermostat.
Tuesday evening, I don’t think the fan came on after I turned the car off after driving home in rush hour traffic like it usually does when the engine is hot after driving. Yesterday morning, on a cold engine start the car did not want to turn over like it had a weak battery. The battery and alternator are new and mechanic has confirmed nothing is wrong with either. Fifteen minutes and four miles later, while driving to work in slow city traffic once the engine heated up the temp gauge continued slightly into the red. The car has always run a little hot but in the past when it would get to the bottom of the red line I presume the fan kicks in and the engine temp gauge moves back down between the hashes. Yesterday, it went just slightly into the red, wiggled a round a little, then the “!” light came on and the engine cut off. I didn’t fool around, I just had it towed to a mechanic. I didn’t try to re-start it but when I turned the key to battery the “!” was still on about 5 minutes after the engine cut off. After towing, the mechanic told me that the car will cut off automatically if the gauge indicates an overheating. Not sure if that’s true of the 968 or not. When the mechanic started it at the shop (engine had been idle for 2 hours) the “!” light was not on anymore but the engine was also now cool. So far, he has replaced the thermostat and is looking for other electrical issues.
Several months ago a mechanic had replaced the battery and a thermostat or relay (or both, not sure) when the fan was staying on after the car was off and engine had cooled. That problem was obviously killing the battery but I’m wondering if this problem isn’t some related electrical issue. I think this may be my third thermostat and second in several months so I suspect the problem may be originating somewhere else. Thanks again for any ideas or help.
