I have a 2002 Ram and last year I had to bypass the cooling system hoses to the heater core inside the cab because it started to leak. I wanted to know exactly how difficult it is if I were to attempt to replace it. I've heard it's a long and difficult process?


Thanks for your feedback guys and gals!

 

Yes. It about 6 hrs of labor. Under the hood you must discharge a/c lines, disconnect heater hoses, clamp off both hoses then disconnect from heater core at the fire wall. Remove computer at fire wall so you can get to heater box bolts, and several other bolts along fire wall. Inside of truck, you must unbolt steering column, also disconnect wire harness connectors, remove the dash. It is a long process.

 

Yeah it sucks. Had to do this couple years ago. If your dash is all cracked up like mine was it's a good opportunity to swap in a good one.
