hi, i have just joined. im from the uk and have just purchased a (gorgeous!) 70 plymouth belvedere, but it has a leaking heater matrix, it looks a nightmare to remove. could anyone please tell me if this is the case or am i just being thick! many thanks. oh, and it does not have A/C.

 

From my Charger/Coronet Service Manual
1. Drain radiator and disconnect battery ground cable.
2. Remove upper half of glove box.
3. In engine compartment, disconnect heater hoses at bulkhead. Plug hose fittings on heater to prevent any coolant from spilling on interior trim as heater assembly is removed.
4. From under instrument panel, remove heater to cowl support bracket.
5. Remove defroster hoses and disconnect wiring from heater motor resistor.
6. Disconnect fresh air vent control and shut-off door cables at heater from under instrument panel. Reaching through glove box, disconect temperature control door cable.
7. From inside engine compartment, remove three nuts that mount heater to bulkhead.
8. Rotate heater assembly until mounting studs are up and carefully remove heater from under instrument panel.

Thank my wife for typing this.
Good Luck and Welcome.

 

thanks very much, i will give it a go, and thanks to your wife for the typing!(i could do with some help too!) again, many thanks.
