Heater Core bypass
Have to do the dreaded heater core but I want to bypass it so I can still drive until I get to it(ASAP). Anyone know the diamter of the lines that go to the core that run through the firewall?

Re: Heater Core bypass
it appears that it is 3/4 inch


Also about the wk heater core, look on youtube, apparently you can just drill out the spot welds on a brace on the dash and slip the heater core out and slip the new one in, then machine screws or weld the brace back in. There was a video on youtube.
