By passing the heater core, is said by some, to help with cooling. I know that running the heater blower will help a small amount if an engine overheats, and the coolant is being routed through the heater core.
This mechanic claimed by passing the heater core completely would help. Who knows???
My wife will not be happy with this I can assure you.....however, since it suspose to be 70 degrees here tomorrow, may not be a problem.
