(j) Bleed air from the cooling system.
(1) Warm up the engine until the thermostat opens.
While the thermostat is open, circulate the
coolant for several minutes.
HINT:
The thermostat open timing can be confirmed
by squeezing the inlet radiator hose by hand,
and checking when the engine coolant starts to
flow inside the hose.
(2) Maintain the engine speed at 2500 to 3000
rpm.
(3) Squeeze the inlet and outlet radiator hoses
several times by hand to bleed air.
CAUTION:
When squeezing the radiator hoses:
• Wear protective gloves.
• Be careful as the radiator hoses are hot.
• Keep your hands away from the radiator
fan.
NOTICE:
• Make sure that the radiator reservoir still
has some coolant in it.
• If the coolant temperature gauge
indicates an excessive temperature, turn
off the engine and let it cool.
• If there is not enough coolant, the engine
may overheat or be seriously damaged.
• If the radiator reservoir does not have
enough coolant, perform the following: 1)
stop the engine, 2) wait until the coolant
has cooled down, and 3) add coolant
until the coolant is filled to the FULL line.
(k) Stop the engine and wait until the engine coolant
cools down.
(l) Add engine coolant to the FULL line on the radiator
reservoir.
