Does anyone know of a site where I can orderthe Canadian version heater core for a Ram Van 1500 3.9 w/AC? These are supposed to have twice the heat output capacity and still fit in the existing heater box without any modifications. Doubling my heating output is well worth the expense, it's just finding the core that's eluding me. Thanks!

 

What works for me is a large piece of carboard right behind the front grill in front of the radiator. Usually, I only cover 1/2 of the face area of the radiator core. This provides ample heat here in the Niagara Falls region I live in. Yes, the V6 3.9L B1500 heat isn't much to write about. The V8 5.2L B2500 has no problems with heat, or heating with the rear unit too!

 

Did you ever find that "Canadian" heater core? Please tell me more.

 

No I never did. I ended up getting the regular one from the dealer and installing it.

 

Don't think there is a disinction, have one out of an '87 if you wish to compare notes.
