Hello all , been sometime since last here.
I replaced the water pump on my 2003 Ram 1500 after it blew up on me, i also replaced thermostat and fan clutch, and belt.
It seems the thermostat is not opening because truck is overheating, i thought there might be a bubble in the system particularly on the thermostat so i loosened the thermostat housing to let water drain, on the engine side of the thermostat it was COLD! While all other hoses are hot as hell besides the hose coming down off the radiator to the thermostat.
I feel there is a bubble in the system but cant seem to figure this out on my own just yet. Do any of you have any suggestions on fixing this issue. What is the coolant bleed valve on the top of the engine, and how or when would you use that?
Thanks so much! - Brian
