Cooling System: Description and Operation

Coolant system
The engine is liquid cooled by a mixture of water and anti-freeze circulating around the coolant passages. The coolant pump is mounted on the LH side of the cylinder block and is driven from the crankshaft nose by a three point belt drive (which includes the alternator). The pump is a fully assembled bolt-on unit. The coolant is fed into the cylinder block at two places via an external delivery pipe. The coolant is drawn from the cylinder head via a self-contained thermostat housing back to the radiator or recirculated according to the thermostat position.
