Inspect for Reuse (008-062-007)
Inspect the water pump body for indications of water leak-
age at the weep hole.
A streak or chemical buildup at the weep hole is not jus-
tification for water pump replacement. If a recurring drip of
coolant is observed, replace the water pump with a new
unit.
Inspect the weep hole to make sure it is open. A plugged
weep hole can cause the water pump to fail.
A small screwdriver or a small tool can be used to remove
any debris.
Inspect the o-ring sealing surface of housing.
Install (008-062-026)
Install the new sealing ring into the pump groove.
