1996 Dodge Ram Van 2500 Q&A
1996 Dodge Ram Van 2500 Question: water pump
Ok so I have replaced sender unit, thermostat and water pump on this Ram Van. Still gets hot but not steaming hot. No heat coming out either. I pulled the water lines from the pump to the heater core. No fluid coming out of the line while idling. Hose may be plugged but unlikely. Question? Does the engine need to heat up enough before it sends water to the heater core?. I suspect that the heater hose will have water circulating from the pump thru the heater core always. Maybe the new pump is defective? Thanks. - Tahoetoddster
there should be circulation at all times. did you bleed the air out of the system??? the no heat is not good. from the sound of your message, you have been running hot for a while. you may have done damage to a head gasket. the radiator may be clogged also, causing a no circulation issue.
