Gets hot and stalls out

I'm in 100% agreement, but for now I'll have to loop them and cap it off at the firewall. I just found out that my significant other is going to be transferred to Houston and I'm in the middle of a full blown renovation of a house that we'll now likely never move into, plus work travel, vacation travel, and a rental property that needs a renovation now that the tenants have moved out, so my hands are pretty full at the moment.
I'll give you this tidbit. Heater cores for some of these are gettin HARD to find, so the sooner you find one, the better.
