I’m having this issue with my truck. So both fans turn on automatically when I start the truck, also I don’t have no A/C. I replaced my thermostat and temp sensor. That didn’t seem to fix it. I should also include that I did a DOD Delete with a stock non dod cam, it’s tuned and engine works fine. It’s driveable but it’s annoying have no A/C and both fans when I start the truck. Please help! -
Installed a new all aluminum Cold Case radiator in my 06 Sierra 1500 4.8L and I’m having trouble getting up to operating temperature in the normal time frame. I would think this will especially be an issue in the winter, but I’m in Texas so winters are no exactly terrible. Is this something I should be concerned about in the long run not reaching op temp on the majority of my drives? Getting my temp to the 200 degree standard operating temp will take me about 40min of non stop highway driving while the fans are running with the AC on. My temp will climb to the 185-187 thermostat opening fairly quickly 10-15min but as it opens and the fans run, it is just too much cooling for it to ever reach op temp in a decent time. Also if I keep my fans off, and it does reach 200 degrees, in 15-25min, once I turn the fans back on, the temp will drop to 185-187 within 5-10min. I know this radiator was a bit overkill for my stock application, but I wanted an aluminum rad to not worry about leaking issues in the future from plastic rads.

Hello, I have a 1997 Chevy C2500 5.7 and I’m having some cooling issues. I recently did a top off of the fluids and changed the oil, we also replaced the coolant with new 50/50. The overflow tank is always completely empty after being driven for even long periods. After checking the coolant in the radiator we realized that it had gone down too. From what I have checked (and I’ve checked everywhere) there are no leaks. There’s no oil in the coolant or coolant in the oil, the top radiator hose is always hot but the bottom is always cold. I don’t know if that has anything to do with it but I thought it was worth mentioning. When filling the radiator back up with water I also noticed it bubbling while it was going down, is it possible there is an Air pocket? It’s important to note that the truck doesn’t overheat, or should I say it hasn’t yet. Even after taking it on a long road trip. Any reason why my coolant keeps going down and not back into my overflow? Thank you for any help! -
Have any of you been able to get GM to cover radiator leaks beyond the b2b warranty? I have 40k on mine and was just informed I have a leak. I noticed they extended the warranty on 14 and 15’s but I’m not seeing any newer models being covered. -
Hey guys, i have a 2005 gmc yukon with electric fans. It is the 5.3 and the electric fans will not turn on. I have replaced the coolant temp sensor and the relays and it is still inop. If i send 12v to the fans they will turn on and constant power is getting too the two 4 prong relays my tools will not fit to test the 5 prong. None of the fueses are blown either and relays have resistance to them. It has a slight hickup on startup but not much of one and sadly no they do not work with the ac on the temp will go straight past 210 when parked

Hey all. latest recruit here. Have been in/around all kinda of garages and shops my whole 40+ years. Recently I made a bonehead mistake. While swapping a 1991 engine into my 1986, I mixed up the fan shrouds and tossed the wrong ones. This is irreversible. It got burned up in my trash barrel by mistake. I now have a 1991 shroud that does not fit my 1986. Every diagram I see shows me this metal panel that bolts to my core support. This is incorrect. My radiator is not tall enough for that. My fan shroud had the radiator cushion integrated into it, I am almost certain. How is it that none of the online retailers have this?? Is my truck a weird one? It unbolted like factory equipment, though it was kinda cracked and broken. The bolts were still in place. The radiator is a 4 row radiator with a 29" core. It is not tall enough for a metal top bracket/panel/whatever its called to hold it. Its about 2-3 inches too short. Im ready to beat my face into the cement. Any ideas guys and gals? -
Hello. My brother seems to have a bit of a weird problem. He recently swapped his belt driven fans for an electrical ones. He did all the wirings and changed the temp Sensor. Although the AC fan works fine, It seems that the radiator fan turns on instantly when the engine is cold, but when the engine reaches the operating temperature it turns off and stays off. What could cause this? Did he flip a wire somewhere?
