: 98 Catera running a little hot? help please

05-11-11, 12:51 PM
My cat runs good but after running for more than half hour when Im at a stop sign or light temp will start to go up from halfway. It goes to next mark on gauge and fan kicks on and it goes back down to halfway. Any Ideas would be appreciated.

I don't think you have a problem. My 1997 works about the same way, depending on the outside temp. On hot days, it will go to the next mark and come down when the fans come on. One thing - I noticed that the car runs somewhat cooler on hot days now that I got the coolant flushed.
