Here's one of those 'Oh no, not again' questions. Ford saw fit to add a heater core bypass hose to the '99 Taurus. My question - what, exactly, does it accomplish. We've been having the usual 'lack of heat' problems, have flushed back and forth but the bypass hose seems to be carrying most of the hot water from the block right around to the pump. I've always thought hot water should go through the heater core and, in line with that, what would be wrong with clamping that bypass hose, allowing the hot water to do just that. I'm thinking seasonally - end of September through May.
