A 5/8" stream of coolant allowed to come from the pressure side of the water pump and then is immediately returned to the suction side of the pump, would seem to be coolant unavailable for cooling. The heater valve on my charger stops flow when off and allows flow through the core when on. My van is constant flow core with a door to keep hot air in or out. In either case if one would remove the core and simply run a hose from the old in to heater and out to heater (from the engine nipples) you will lose the cooling that the heater core would normally give you. A friend here in Phoenix first passed this observation to me when he almost cooked his 360 motorhome coming accross from the sand at Yuma. He had a leak in one heater hose, he looped the non-leaking one back to the block. He went about 20 miles, had 250+ water temp...cooled it down....checked coolant level, kinked the hose and clamped it to stop the flow...ran 210 the rest of the trip. This summer come on down when its 115 and we can run one of my big blocks both ways to test the theory...try it with pipe plugs in first, then with a bypass hose. I suspect if you have a super capacity raditor or weather that never sees 90 degrees you might never have a problem. rob lipinski > > > >>>>From: "Brian Safford" <bsafford@xxxxxxxxxxx> >>>>Subject: Heater core leaks >>>> >>>>I've installed a short hose between the manifold and water pump - is that >>>>okay? >>>> >>>>Regards, >>>>Brian Safford >>>>'62 Dodge Dart 440 >>>> >> >> >> >>In phoenix az summers simply bypassing the heater might cause overheating >>as a large volume of >>water nevers goes through the radiator. >> >>Non-heater cars have pipe plugs instead of the hose nipples. >> >>Other climates may have no problems. >> >>Two cents from Phoenix Az. >> >>rob lipinski >>65 sat 361-4spd =========================================================== Sign up to get FREE information from leading colleges!
