1993 Ford Ranger Q&A
1993 Ford Ranger Question: how do i change the heater core
Replacing the heater core is easy - just disconnect the heater hoses, remove the cover screws under the dash, and pull it out. Reverse for reassembly. You can try to flush the core with it in the vehicle. You didn't say whether or not you checked why you're not getting heat. - Superbob
Can I change the heater core on my 1990 ford ranger myself? Do I have to take the dash down or is there another way?
