Heater Core Bypass

[PewterBird]

To bypass the heater core, do I just splice those two heater hoses together?

Re: Heater Core Bypass

I haven't done the bypass yet...because I am still trying to diagnose the overheating issue. Today I filled her back up with water/coolant and turned on the heat. The air never got hot, and I witnessed it overflowing out the overflow cap.

Does that mean my heater core is clogged and it is causing the coolant to divert back to the overflow?

Did the bypass and it was really easy. But I think the overflowing coolant screwed up the battery. The post fell off.

So when you by passed the core did it help your problem? What kind of Fbody do you own?

I don't know yet. I have to get a new battery in there and buy more coolant.

Ok time for an update.

New battery is in. It runs just fine. I drove it home and got a bit of steam comming up out the cowl.

It had not overheated yet after about an hour of driving and idleing. When I got it home it did dump a bunch of coolant on the ground. But the coolant was cold. I am thinking it might have come the section heater hose I bypassed, because it was cold. And that could have explained the steam too.
