Grand Prix be running

Post by xeshilva »

At what temperature should my 99 Grand Prix be running at in about 95 degree heat? My Grand Prix has been running at around 210. Even on the freeway it cools down to about 180. I dont remember last summer it running so hot. Its been between 95 and 105 lately. Is that a normal temp for it to be running at?

The standard themostat temperature is 195. It could get to 210 or so on hot day in traffic, but the radiator fans should be on at that time, too. It should not get much below 195 when the engine is warmed up.
