I have a 1994 Silverado 4 wheel drive v8 5.7, it has very little heat. I have flushed the radiator, cleaned the heater core, put in a new themastat. Checked the water pump seems to be working fine.

I discovered this problem after putting a plow on the truck and it over heated, I have also changed the fan clutch. Can anyone please help.

Thanks

 

does it ever warm up? cause im having kind of the same problem. but my truck will start gettin warm after a long drive, actually it'll begin to get warm right when im pulling into work way after the engine and properly been warmed up and drivin on the freeway. Im trying to fix my problem right now, so if its the same thing let me know and when i find out ill keep you posted.
