my car ran hot today... in normal traffic (not stop-go, just normal city driving) the water temp was at 100F after 6 mi worth of driving with the A/C on. The temperature kept going up until about 105F.
That was after some highway driving. I have a feeling something is VERY wrong. The only thing I did to the cooling system was replace the '100' marked radiator reservoir cap with a '140' cap that I bought from fastlane.
I just put the 100 back on..
It was 95F outside today. I have run the car in 102F weather and the max it reached was 101F. I knew it wasn't good either. However that was after miles and miles of driving...
I'm gonna get the system flushed and refilled tomorrow. I'll probably have the shop replace the t-stat while at it. Hopefully that'll fix it. Otherwise.....
The fan clutch works though as it's hard to turn when the engine is off (the engine was hot). It also stopped turning immediately once the engine was shut off (hot engine too)
The aux fan works great..
The coolant system isn't losing any coolant..
It kinda sucked... my A/C now cools the car extremely well (even in today's hot weather). The air coming out of the vents was definitely colder than my friend's Chevy Malibu and Toyota Highlander (quite an achievement I say). However the interior wasn't quite as cold.
just had to overheat.. I'll update the results tomorrow!
wish me luck
