Today i was in traffic with the ac fulll blast and i had a check engine light pop and i noticed the temp was rising very slowly. I turned off the ac and pulled over and popped the hood and gave the once over and nada. Both e fans where running and with the ac off the temps went back down to normal. I got home pulled neg battery cable and let it sit. 20 mins later went back out to start it and drove it around with the ac off and normal temp and no code. anyone have anything like this happen to them?? I was thinking maybe t-stat or just that it got to hot sitting in traffic with the ac on. I bought a new t-stat just in case it acts up again. thanks guys in advance

 

What stat are you running and are using Dex-cool? Last maintenance?

 

Stock t-stat. Using dex-cool and was flushed out during the cam swap 3 weeks ago

 

Orig stat too, 180?

 

yes mam. orig stat

 

I'm going to say that it's not the T-stat (it's never the T-stat)...t-stats generally are good or bad and are designed to fail in the open position. Maybe a blockage between the radiator and condensor (such as leaves and debris). The ac puts a big load on the engine, and summer's coming. I know it's been three weeks, but there still could be air trapped system from the cam swap also...

 

how do i get air out of the system? remove the coolant tank cap?

 

It's like the system has to be burped... I know .... it took mine a long time, over an hour.

 

you need to scan the code. How else can you know what was going on?

 

about to go do that in the next hour
