Lloyd Posted January 8, 2020 Report Posted January 8, 2020 The heater Shut off valve will be threaded into the top of the head towards the back. One of your heater hoses should connect to it. You may not have one, my original engine just had a 90 degree pipe threaded directly into the head. Are both the hoses cold or just one? If just one then somethings stopping the flow. If both then no flow. With the engine running try removing the return hose at the engine and see if you have flow. Its messy but quick. Quote
Dartgame Posted January 8, 2020 Report Posted January 8, 2020 Depending on the style of heater should be at the back rear passenger side of the cylinder head ? Quote
Dodgeb4ya Posted January 8, 2020 Report Posted January 8, 2020 The upper line Dodge Coronet could have the firewall mounted "Ranco" heater water temperature control valve. It might be stuck closed causing no heat. 1 Quote
Jamie Anderson Posted January 8, 2020 Author Report Posted January 8, 2020 Sorry for the slow response I'm at work will look when I get home Quote
DJ194950 Posted January 8, 2020 Report Posted January 8, 2020 What models of heater is it? Does it sit on pass. side inner fender? Some of the 1949-50-51-? have a lever on the top of the heater core box that when in the wrong position allow all the heater air flow to by-pass the core- fresh air only, no heat added! Just a thought. DJ Quote
greg g Posted January 9, 2020 Report Posted January 9, 2020 (edited) look real closely behind the #6 spark plug. This has the manual heater valve with a thumb screw on the top. If this is open you should have flow to the heater core. The other line goes from the core to the suction side of the water pump. If both are warm you should have hot coolant to the heater. Doesn't matter which line goes to which of the heater core but you might try swapping and see if anything is different. This maybe a later model but the workings are the same. You can see the return line behind the fan pulley at the top of the pump. Edited January 9, 2020 by greg g Quote

Plymouthy Adams Posted January 9, 2020 Report Posted January 9, 2020 the 104 and 105 heater both have the internal control valve Dodgeb4ya mentioned above located on the passenger side of the firewall inside the cab....the routing of the hose is also an item that need to be correctly connected, output of the engine at the back corner connect to the curved side of the valve...the 104 uses multi-boon control panel, the 105 has the globe control. Have you verified you block temperature is adequate for heat. No thermostat and odds are you may not reach a temp sufficient for heat transfer to occur. Folks here need a bit more info or as stated, pictures speak volumes at times. Quote

desoto1939 Posted January 10, 2020 Report Posted January 10, 2020 the hoses going into the firewall are the heater hoses approx. 3/4 round. This is what supplies the hot water to your heater. Rich Quote

Plymouthy Adams Posted January 10, 2020 Report Posted January 10, 2020 it enters the firewall to connect to the Ranco control valve as Bob pointed out in thread #9 of this topic...had you followed the hoses end over end an looked inside the car should be fairly obvious...I am going to ask if you have a repair manual to go by…..if not, and you wish to work on your car, it is a good investment Quote
