If I want to give up and bypass it which hoses do I route ?
Might be able to get it from under the hood. That's how I changed the core on my Dodge van, after I broke it. The two hoses feeding your heater core are about 1 inch diameter, and they atach just front of the passenger seat. Under the hood.
I vaguely remember there being a small screw just between the two protruding pipes (Or just above) on the firewall side. (Phillips. I think).
7mm...jp
you did take the two tin straps that hold it in place CLEAR out of the way? Right? jp
by the way-you shouldn't have to pull the dash-got a manual-Chilton, Haynes, GM? Should provide allittle help- good luck. jp
Did it; easy - and worked all winter (just wore warmer coats) (the two hoses have different sizes ! That was the only PITA; had to clamp down hard on one)
