2000 Dodge Durango Repair Question
Dodge Durango Heater Problem
Your test method isn't accurate. There is no pressure pushing the coolant when you remove one heater hose. It is just as necessary to have some "pull" on one hose as it is to have the "push" on the other one. Instead, feel the hoses after the engine has been running a while. They should be too hot to hold onto for very long. If they're not, suspect the thermostat.

Ok that makes sense. The inlet hose to the heater core gets hotter than the outlet hose. Neither one gets as hot or close to as hot to the radiator house.
