I have a 1987 4wd van. The car had coolant leaking problems when I got it, and I suspect the previous owner may have used Bars Leak, with the pellets to try and fix the problem, and it clogged the rear heater core ( the little radiator unit that heats the rear part of the car ). The front heater core never worked either, but I know they are much harder to change out, as they are buried in the front dash. I have a question or two regarding this dilemma
Does anyone know if other years models are basically the same and can be used in this model/year ?? ( ie are they interchangeable )
Secondly, any idea whether rear wheel drive models of the same year ( or other years ) have the exact same heater models ( they may well ),
or same thing, are there some other years of the RWD models may be interchangeable ???
Thanks for any input.
