Description - Water Pump Bypass - 3.7L

DESCRIPTION - WATER PUMP BYPASS - 3.7L





The 3.7L engine uses an internal water/coolant bypass system. The design uses galleries in the timing chain cover to circulate coolant during engine warm-up preventing the coolant from flowing through the radiator. The thermostat uses a stub shaft located at the rear of the thermostat to control flow through the bypass gallery.
