5.1 DESCRIPTION
The centrifugal coolant pump, which is positioned inside
of and driven by the engine, draws cooled coolant from
the radiators, and distributes it throughout the various
cooling galleries in the cylinders and heads to maintain
the engine and its internal parts at the proper
temperature.
The path of the coolant leaving the engine varies,
depending on coolant temperature, and is illustrated
below.
The expanded volume of coolant, caused by the increase
in temperature, is compensated for by the expansion
tank.
Refer to the “LOW” and “FULL” reference marks to check
and top up the coolant, see 2.14 (CHECKING AND
TOPPING UP THE COOLANT). For more information
about coolant, see 1.3.7 (COOLANT).
