Engine Maintenance (Rev 6/98)
54
operate the unit in accordance with instructions of
the flushing agent manufacturer.
c.
Open the engine block drain to drain the water and
flushing solution.
CAUTION: Avoid direct contact with hot
coolant.
3.
Run clear water into the radiator, and allow it to drain
out of the block until it is clear.
4.
Inspect all hoses for deterioration and hose clamp tight-
ness. Replace if necessary.
5.
Loosen the water pump belt. Check the water pump
bearing for looseness.
6.
Inspect the radiator cap. Replace the cap if the gasket
shows any signs of deterioration.
7.
Mix one gallon of permanent type antifreeze concen-
trate meeting GM 6038-M specification and one gallon
clean water in a container to make a 50/50 mixture.
NOTE: Do not add antifreeze and then add water to
the unit. This procedure may not give a true 50/50
mixture because the exact cooling system capacity
may not always be known.
8.
Refill the radiator with the 50/50 antifreeze mixture and
make sure to bleed the air from the cooling system as
needed.
Bleeding Air from the Cooling System
Normally, when the cooling system is drained, approxi-
mately 7.6 liters (8 qt.) of coolant drains out. If approxi-
mately 3.8 liters (4 qt.) of coolant seems to fill the cooling
system after it has been drained, air has been trapped in the
block. Bleed the air out of the block using the following
procedure:
CAUTION: IF YOU SUSPECT THAT AIR IS
TRAPPED IN THE BLOCK, DO NOT START
THE ENGINE WITHOUT BLEEDING THE AIR OUT
OF THE BLOCK.
NOTE: If an engine runs with air trapped in the block, the
engine may be damaged. The high water temperature
switch may not protect an engine that has air trapped in
the block, because the high water temperature switch is
designed to protect an engine from overheating due to fail-
ures in the cooling system and the loss of coolant.
1.
Disconnect the bypass hose from the thermostat hous-
ing before pouring the coolant into the cooling system.
2.
Slowly pour coolant into the system until you see cool-
ant at the bypass hose fitting on the thermostat housing.
3.
Connect the bypass hose to the thermostat housing.
4.
Pour coolant into the system until it appears to be full.
5.
Make sure that the amount of coolant that goes back
into the system is approximately equal to the amount of
coolant that came out of the system.
6.
Start the unit, let it run for one minute, and then shut it
off.
7.
Check the coolant level and add coolant if necessary.
8.
Repeat steps 5 and 6 until the coolant level stabilizes.
