Yes, it is cooler outside, but it was in the high 30's 2 weekends ago here and my thermostat was at normal temp, just a little lower than halfway. Saturday night, it was only one quarter of the way up. When I would turn off the heater, it would climb to its normal temp, but turning the heater on made it drop quickly, really quickly. It wasnt cold enough outside to do this, it has been in colder weather and not acted this way. Car has never done this before. I checked the coolant level obviously, and its fine. What should I check?

 

mine hardly every goes to normal, when I'm driving mostly highway on a cold day. I think its probably normal.

Thermostats have been known to stick open. I haven't looked at my water temp gauge recently (useless piece of crap) but my oil temp only made it up to 150 degrees this morning (20 minute commute).

Using the heater will definitely cool the coolant.

 

I think cause your fantasy football team is owning mine, I put a curse on your RRRR

 

My temp gauge stayed at cold yesterday even after 1hr of driving I think its due to the freeezing weather it was -35 with the windshield outside

 

Yup and they say it's -47 today with the windchill

 

wow and i complain when its 30 outside. cant imagine -30

 

Just changed my tstat last month. It was stuck open and had would not reach optimal temp, ever...especially on the highway.

New one = driving 250 miles in single digit temperatures, no problems.

 

i have the same problem too
