ANOTHER heater core question!
Sorry about this, I know heater cores come up every other day on this forum but I have another question. I bought a hight output heater assembly from a junkyard. Upon pulling it all apart I found that the genius who owned it before bought a regular heater core and shoved it in there, and then filled the extra couple inches of opening with carboard. I picked up a new heater core yesterday (proper high output core) but it fits very loose in the opening. Hayne's manual says something about a foam gasket, which I don't have of course. Does anyone know where to find these gaskets OR could I use some of that round foam pipe insulation to hold the core in place?

i bought the wrong one too and used cardboard to fill the rest there are two pieces of rubber one on the top of the heater core and one on the bottom they sell them for 3.00 at a parts store or you can use flat rubber weather stripping at a hardware store about 5.00 and the weather stripping comes in all different sizes so that might work better

same problem here. Bought some double sided tape and 1 inch foam weather stripping. taped and put on the foam, put it in tight, and haven't had a problem. that was 5 months ago. Just a helping hint here, check your blower motor to make sure it runs well before sealing up the core. I forgot to check mine, and guess what? The motor didn't work and I had to pull the whole thing out again 3 weeks ago.

Funny you mentioned that. I tested the blower earlier today and it was dead. 
Not a big deal but I'm glad I found out before I installed it. One advantage I'll have is I'm converting from an AC system to a non-AC heater. I have a panel that covers up the big hole in my firewall. If I ever need to replace the motor or heater core I just remove the panel, not the whole heater assembly.

but, going from ac to non ac means you will use the a/c blower from the factory. The non a/c motor will not hook up to the a/c motor. Its a different pattern on the bolts. Its not in the same place either.

I ditched the whole AC unit. I'm using a whole different heater housing with a high output heater core. The blower motor that came with it is burned out but I'll be replacing it with another from the same style housing, not from the AC housing.
