Component Tests
Pressure Test
A WARNING:When releasing the system
pressure, cover the expansion tank cap
with a thick cloth to prevent the possibility
of coolant scalding, Failure to follow this
instruction may result in personal injury.
1. Remove the coolant expansion tank cap.
2.
Install the special tools to the coolant expansion
tank.
3. Pressurize the system to the
coolant expansion
tank cap

4. Observe the
cooling system pressure tester
gauge reading for
approximately two minutes.
The pressure
should not drop during this time.
If the system holds pressure, proceed to step
6.
If the system does not hold pressure, check
it
thoroughly for coolant leaks.
5. Check the engine for coolant leaks. Drain the
cooling system, repair any coolant leaks found
and
fill and bleed the cooling system as
necessary.

Clean the radiator thoroughly before leak testing
it, to prevent contamination of the water in the test
tank. Leak test the radiator in
clean water with 138(

air
leaks. INSTALL a new radiator if necessary.

Coolant Expansion Tank Cap Pressure Test
A WARNING:When releasing the system
pressure, cover the expansion tank cap
with a thick cloth to prevent the possibility
of coolant scalding, Failure to follow this
instruction may result in personal injury.
1. Remove the coolant expansion tank cap.
2. Use water to clean the area of the rubber seal
and pressure relief valve. Install the pressure
tester and adapter and immerse the
coolant
expansion tank cap in water .
N0TE:lf the plunger of the pump is depressed too
quickly, an erroneous pressure reading will result. l-
3. Slowly depress the plunger of the pressure test
pump until the pressure gauge reading stops
increasing, and note the highest pressure
reading obtained.
4.
Release pressure by turning the pressure relief
screw counterclockwise. Tighten the pressure
relief screw and repeat step 3 at least twice to
make sure the pressure test reading is
repeatable and within acceptable gauge reading
limits of the coolant expansion tank cap.
5.
If the pressure test gauge readings are not
within the
acceptable gauge reading limits,
INSTALL a new coolant expansion tank cap.
6. Recheck the system by repeating steps 3 and
4 at least twice.

result.
1. Connect the WDS to the data link connector
