Heater core/Blower motor

[Zeegs]

Not completely sure if this is the corect section to post in, but AC is in here. My heater core is hooped and needs to be replaced. When I went to order a new one (89), I was asked if mine was copper or aluminium? Which one do I order, or is there even a difference between the two?

Also, I'm gonna replace the blower motor while I'm at it. Is Everco a good brand to go with?

IIRC the 89's used a copper core, and the 90's changed up to the aluminum core

When you pulled your heater hoses off of the core, was it copper or aluminum colored?

That would make sense They are copper, would the aluminum core fit, or is their a difference?

Ack! Good luck on that job. Labor intensive.
I would go with the copper if that's what the pipes are. What is the reaction when these 2 different metals interact in that environment? Not sure, but with a heater core it ain't a job you'll want to do twice.

When I had the dash out on my old 89, I tried to put a Aluminum heater core in to the case, but was unable to due to the difference in widths, and hight, and how the pipes are bent, so I had to go with the copper core

Thanks, I'll try to find a copper one!
