2002 dodge ram 1500 quad cab overheating need help please
Okay i have a dodge ram 1500 and the truck overheats if i leave the thermostat in if i have the thermostat out it just runs cold i have went through four thermostats and test the thermostats and they work good. I have replaced the radiator (cause someone told me to rev the engine in park and i did and it blew the radiator) also replaced the water pump. Replace the head gasket as well got the heads machined and all cause the truck got hot one time. The truck starts overheating right away after it reaches operating tempature i have also had a temp gun on the engine and it is getting hot replaced the cooling temp sending unit too. New cap on the resiovior as well. any ideas or something i miss maybe
You could have air in the system that is not allowing the thermostat to open. Would be my first guess if it's running cold without a t-stat and overheats with one and the t-stat is known to be good.
