COOLING SYSTEM
THERMOSTAT
A thennosta~ located near the manifold at the' front of the
engine, controls the coolant temperature as the coolant
continuously flows through the closed cooling circirit. When
the engine is first started, the closed thennostat prevents
coolant from flowing (some coolant is by-passed t)rrough a
hole
in the thermostat to prevent the exhaust manifold from
overheating). As the engine warms up, the thennostat
gradilally opens. The thennostat is accessible and can be
checked, cleaned, or replaced easily. Carry a spare thermostat
and
gasket
A coolant recovery tank allows for engine coolant expansion
and contraction during engine operation, without any·signifi-
cant loss of coolant and without introducing air into the cool-
ing system.This· tank should be located at or above the
engine manifold level and should be easily accessible.
