I haven't checked yet to see if my coolant pump is working since this began but im pretty sure its fine but.. The last two days ive been driving around normally and while waiting for some friends to go into a store and come out ive watched my coolant temps go up all the way to 219* when normally my car stays at a constant 187*. As soon as i start driving though the temp drops back down into the 180's. I have never seen this happen before with my car so what do you guys think is going on?? Is anything even wrong?? Summer has nothing to do with it either since it has been like 70* out while this is happening. What do you guys think?

 

perfectly normal while idling. You're fine.

 

wow glad mine stays at 183 and only goes to 195 then the fans kick in

 

you're not on a GM tune, the GM tune has the fans kick on at 220 or so, or if you get an aftermarket tune you can get them to kick on sooner. Mine kick in at 192.

 

219 is perfectly normal

 

thats normal, around 223 he fan will turn on, or u can urn ur ac on and tht will do it too...i have a switch wired to my fan's high speed, settings, and the low is always on

 

has anyone given any thought about changing the thermostat and then adjusting it through hp tuners to turn on.

 

thats why mine says intense stage 3 tune in my sig
