Dont jump all over me - we are restoring a 70 chevelle and everyone hear at team Chevelle has provided a wealth of extremely helpful information - however this is a 96 Dodge Ram pickup truck, 2500 V10, gas engine heater question, so be nice.

The truck's operating tempeture is 200, which it reaches easily and basically maintains. However, with the heater blowing, the air inside the cab does not get that hot - it feels basically warn only. The water level is right on. I'm thinking possible heater core? Any help would be appreciated.

Maybe the valve that opens the flow of coolant to the heater core is not opening? I am not sure if they use an electronic valve or a vacuum valve, but its a place to start.

I don't know if the heater controls are vacuum or electrically actuated, but there may be a door in the heater box that is not opening (or closing) properly. I would check under the dash and make sure all the wires and vacuum hoses are in place and that none are broken, kinked or nicked. The heater hose valve may not be functioning all the way because of a vacuum problem or it might be clogged. Flush the core. It might be clogged too.

feel the heater hoses and see if both of them are too hot to touch, if so, you may have a inner door problem, if not, a heater core or coolant blockage.

exactly whav chev 64 said. check your heater hoses if they are worm , then that means you have a clog somewhere in the heater valve, which is vacuum operated or the heater core is clogged.

Thanks guys - I will check it out tonight.
