INSPECTION
Check general condition of hoses and clamp tight-
ness.
DRAINING THE SYSTEM
WARNING : Never drain or refill the cool-
ing system when engine is hot.
To drain the cooling system, siphon the coolant
mixture from the coolant tank. Use a primer pump
with a plastic hose inserted as deep as possible
into the lower hose.
When the coolant level is low enough, lift the rear
of vehicle to drain the radiators.
DISASSEMBLY AND ASSEMBLY
3,4, Sender and Plug
Apply thread sealant on sender and plug to avoid
leaks.
1, Pressure Cap
Check if the cap pressurizes the system. If not,
install a new 90 kPa (13 PSI) cap, (do not exceed
this pressure).
6,7, Radiator and Radiator Protector
Insert radiator protector into radiator C-rail and
crimp C-rail at both ends. Refer to FRAME 09-02
for radiator removal.
5, Thermostat
To check thermostat, put in water and heat water.
Thermostat should open when water tempera-
ture reaches the following degree.
On 454, 583, 599, 670 and 779 engines
, the ther-
mostat is a double action type.
a. Its function is to give faster warm up of the en-
gine by controlling a circuit ; water pump – en-
gine – coolant tank. This is done by bypassing
the radiator circuit.
CLOSED THERMOSTAT AND COLD ENGINE
1. To reservoir
2. From cylinders
b. When the liquid is warmed enough, the ther-
mostat opens the circuit, water pump – engine
– radiators coolant tank to keep the liquid at the
desired temperature. (See the diagram of the
exploded view).
