Pressure Test
A WARNING:When releasing the cooling
system pressure, cover the coolant
expansion tank cap with a thick cloth to
- prevent the possibility of coolant scalding.
Failure to follow this instruction may result
in personal injury.
N0TE:lf the coolant expansion tank cap is rotated
counterclockwise by 1 12 a full turn, the pressurized
coolant will be vented to the underside of the
coolant expansion tank cap.
1. Remove the coolant expansion tank cap.
2. Install the special tools 303-396 and 303-396-01
to the coolant expansion tank.
3. Pressurize the system to the coolant expansion
tank cap release pressure.
