Hey All,

I have a 2017 Chevy Traverse...mornings out here in SoCal are about 75* (not very hot) and dropping the kids off at school I am noticing that the temp jumps a bit sitting in stop/go traffic waiting in line to drop off but it comes back down with the fans. Pull back in the driveway , let my wife out before I pull up to the garage and within about 30 seconds the temp jumps but comes back down with the fan. Never overheats, reservoir is full, haven't noticed any water pump seeps, etc. I know that cars heat up but this seems a little quick vs. what I am used to?

I know that the gauges are basically dummy gauges on the dash unless they hit red or are Chevy's actually accurate?

Any suggestions or feedback? Figured I would ask before dropping cash at the mechanic for something simple I could do or something that is normal.

Thanks!

Does your Traverse have the louvers that close off the front of the radiator ? Look through the grille and see. Have had the little motor or the lever from the motor to the louvers break on some cars. If they are shut it will heat up really fast.

It doesn't...reservoir is full and I checked the radiator is full also. Maybe I am over thinking it?

GM temp gauges are usually controlled by the BCM, not the temp sender. Regardless of engine temp, if it is within normal parameters, the BCM (or maybe the iPC module?) will keep the temp guage stable in an expected and non-alarming position.

Example…my temp guage reads about 190 degrees when coolant temp is between 170 and 247 degrees.

If a temp guage is moving past the 1/2 way point, typically that’s indicative of a problem…

When it starts to climb a bit, check that the fans are kicking on. Also make sure they’re running when the A/C is turned on.

Toyota’s work the same way….temp guage is always just below half. If the temp guage is ever at or past the 1/2 way point and it’s full of coolant, I would bet money that a head gasket is starting to fail.

It sucks the automakers keep increasing the t stat temps on motors. My guess is its an emissions thing? My 2018 Sierra has a 207 degree tstat on the coolant side and 190 degree t stat in the transmission too, why?
