WARNING: IF VEHICLE HAS BEEN RUN RECENTLY,
WAIT 15 MINUTES BEFORE REMOVING CAP. PLACE A
SHOP TOWEL OVER THE CAP, AND WITHOUT PUSH-
ING DOWN, ROTATE IT COUNTERCLOCKWISE TO THE
FIRST STOP. ALLOW FLUIDS TO ESCAPE THROUGH
THE OVERFLOW TUBE. WHEN THE SYSTEM STOPS
PUSHING COOLANT AND STEAM INTO THE CRS
TANK AND PRESSURE DROPS, PUSH DOWN ON THE
CAP AND REMOVE IT COMPLETELY. SQUEEZING THE
RADIATOR INLET HOSE WITH A SHOP TOWEL (TO
CHECK PRESSURE) BEFORE AND AFTER TURNING
TO THE FIRST STOP IS RECOMMENDED.
CLEANING
Use only a mild soap to clean the pressure cap.
INSPECTION
Hold the cap in your hand, right side up (Fig. 18).
The vent valve at the bottom of the cap should open
with a slight pull. If the rubber gasket has swollen,
preventing the valve from opening, replace the cap.
If any light can be seen between vent valve and
the rubber gasket, replace the cap. Use only a
replacement cap that has a spring to hold the
vent shut.
A replacement cap must be of the type designed for
coolant reserve systems. This design ensures system
pressurization.
ENGINE BLOCK HEATER
DESCRIPTION
The heater is mounted in a core hole (in place of a
core hole plug) in the engine block, with the heating ele-
ment immersed in coolant (Fig. 19). The engine block
heater is available as an optional accessory. The heater
is powered by ordinary house current (110 Volt AC)
through a power cord and connector (Fig. 20).
