Except for a leaky heater core, what other reason would someone have to bypass the heater. Just trying to figure out why mine was bypassed by previous owner. The car has A/C, but I'm not sure if it works.

The only logical reason to bypass would be a leaking core, but I've found in alot of old Z's it's the heater control valve leaking, not the core. when I bought mine it was bypassed, I took the valve out and hooked it up without it and it was fine...it's still working great, I just put a manual valve on it. The stock ones are expensive and I'm not building a show car...cost me seven dollars.

They live where it's always warm and sunny. Simple.
Then again, have you tried replacing the heater hoses on a 73 240 Z? Bypassing the core and suffering isn't such a bad option. :-0

What type of valve did you use?
