- I have an 04 Suburban 1500 automatic with 167k. I noticed that it overheats when the truck is idling. Temp gauge doesn't go all the way but stops always 3/4. In a Scotty video says that's not good. What could be the problem?
Check thermostat and cooling fan operation, and check the radiator for clogs.
You have to check all the components of the cooling system - fans, radiator, radiator cap, thermostat, heater core, age of coolant, belts and hoses, everything.
Is there any videos y'all recommend on how to check everything? I actually changed the radiator fluid last year. Had to clean it really good because it was just water an was brown where components were rusting. Poured some of the stuff to deep clean it with water how the instructions said. Did that twice until the water was running clear. I want to say I did a good job because the following winter was the freeze that hit Texas an my truck had no problems. I have no radiator cap, so that's one off the list.
Thanks in advance!!
Thank you, I'll check everything with this.
So I started with the basics on checking everything. First was the coolant, an it was too low. Lol an that pretty much solved the problem. But for some reason my a.c. doesn't blow cool air no more, just ambient temp. How is that work?
