Made a post similar to this one, I've noticed my coolant temp doest get above 90c during these winter months, temperature is anywhere from -3 to -20. Curious to know if this is a tstat issue. Truck is a 14, crew cab, 5.7, with active grill shutters. Checked coolant and it looks clean with no residue on the rad cap, expansion tank is the same, heat works good. I heard replacing tstat is fairly easy and doest take long at all, if so what is the proper way to bleed the air from the system and what tstat is best.
