C2 Heater core replacement (non A/C)

[Dwight P.]

Heater core was leaking and I have now removed the entire heater box and blower motor. I have a new core ready to install, but since I have everything out why not replace/rebuild the blower motor? Is it cost effective to rebuild the old motor or just purchase a new one? If rebuilding is the way to go, who is the best serice available?

if your original motor is still functioning, i'd re-use it.i have never had one of my midyear heater motors die. mike

Mike:
My motor is original to the car and I am concerned that sometime in the near future the 41+ years will finally catch up with the motor. I am not excited about the prospect of disassembling and reassembling again.

My experience with electric motors is similar to yours....I have had very few electric motors die no matter how old or how much usage.

Is there any test that can be applied to check for deterioration or pending failure? I have never heard of such a test but there are many, many things I have not heard of.

I will ponder for a while.

Thanks for your info..

There's no real 'test'...

As long as the motor's bearings are good (you don't hear 'squealing') and the brushes still have carbon life left, a used motor is going to show essentially the same characteristics as a new or rebuilt motor...

Re: There's no real 'test'...

the motor is an easy swap after the core and box are back in. i am in the middle of this restoration now. i tested and repainted it and it seems strong on my 66. it is the original dated blower and i never considered replacing it at all. what you should address is cleaning and lubing all the controls intalling a new seal kit and fire wall insulation kit if needed at this step. i beleive the motor can be oiled but do not know for sure.

double check the inlet outlet tubes on the replacement core as i have had the re-pops tubes are incorrect---the lenght of the tube from the core to the elbow bend is too short causing fit problems---i took the original harrison core and the re-pop to a radiator shop and had the end plates from the org. put on the new core---cost $20 and fit excellent---good luck

Phil:
I was forwarned by several NCRS guys and was planning to do as you suggested, but the Delco replacement core was almost identical to the original....just a 1/16" narrower in width. All other dimensions were right on. The new core fits into the frame/bracket just fine and the brass hose connections extend through the firewall exactly as the original did.
I was expecting a real "pain" when I started the job but have been pleasantly surprised at the ease of it so far. Perhaps the "pain" will begin when I get into the final assembly.

Thanks for your input,
