351-W By-Pass Hose Configuration
The water by-pass on many 351-W's routes from the thermostat housing to the water pump requiring the use of a formed hose with very tight bends. On some engines this hose turns so tight that it can crimp closed, creating cooling problems during engine warm up. The illustrations below include an alternate routing that eliminates the need for this special formed hose and reduces the risk of a crimped hose.
