[QUOTE="bobbie-g, post: 1611, member: 26"] Don't know about the 642, but in general, the thermostat must open before coolant flows to the radiator. In order to provide coolant flow (and heat) to the heater, there's a bypass connection coming from the water pump to the heater core, and a return back to the block somewhere. This lets hot water circulate thru the heater core when the t'stat is closed. I've not yet figured out where this connection is on my 751, but will have to solve that puzzle at some point. Where'd you buy your heater? ---Bob [/QUOTE]
