Cooling System Features

The cooling system incorporates a new style water pump which is integrated into the timing case cover (similar to the M70). The pump features a ceramic axial seal, a plastic impeller wheel, and an aluminum pump housing which promotes a longer working life, reduced weight, and high efficiency.



The thermostat housing located at the front of the cylinder head contains a thermostat that is designed to open at 88~C (190~F). Coolant flows from the front of the engine block to the rear. At the rear, the coolant rises through connecting passages into the cylinder head and flows from the rear back to the front.
