    Hi all and Happy New Year!!
    I THINK my heater control valve took a walk as I HAD TONS of heat, now none. I changed thermostats, and did a by-pass of the Throttle Body heater while I was in there as it wasn't done yet. (Cut out the Air filter louvers too on the filter top.) Also MAF Screens and heat sinks. A bit peppier and happier now.

    Is there a way I can by-pass the heater control valve?

    Hi all....
    I got heat back, bypassed the heater control valve till Corvette Specialities gets my new one in. I also reverse and forward flushed everyhing. heater core, block, and rad. the fellow that owned the car before me did not take care of the beast. i found a bunch of rust in the coolant which turned out to be mostly water.

    Well done Darrell. :thumbs:

    Good luck with the installation of the new part, at least you know what the issue is. Heat. We could all use some of that right about now.:cool:
