low or no heat,coolant level is fine,can the heater core be flushed&is it a problem to replace&
how do i change the heater core on 1993 Ford Ranger
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.
