GM. Last summer/fall (the difference is overnight here in San Antonio) I was driving home in traffic and my truck overheated. I pulled off and let it cool off. Finally was able to get home. I swapped out the thermostat (98K miles), flushed and replaced the coolant. Seemed to run just fine, but the weather did cool off.
Fast forward to present. Was driving home (temp was around 70) and my temp gauge shot up to 241. I also noticed I didn't have any hot air from the heater. I pulled over and let it cool off, and then drove home (very short drive). Truck now has 104K on it. When I checked the coolant, it was almost a gallon low! No puddles, nothing. My engine also has no oil leaks, runs great. Filled it back up and decided to go ahead and swap out the water pump, upper and lower radiator hose and top off the coolant. Took it for a drive, seemed fine...was staying at around 190 then it started climbing...got up to 225. When I arrived home, I discovered a small leak coming from the upper radiator inlet hose. Sure enough, there is a minute crack in the neck. Ordered a radiator, got it replaced, and no more leaking. However the temps seem the same, then starts climbing back up. I have noticed that my fan only stays in low speed, and never goes to high speed, as it used to do. Could this indicate that the fan motor/electronics in it are going bad? It is a electronic PWM fan.
Any help would be greatly appreciated. I am not a mechanic, but I try.
Semper Fi!
