CAUTION
Cavitation can occur when pumping and air enters water.
If engine speed increases without an increase in pressure,
pump may be cavitating. Even though pump may be
primed, air leaks can cause rough operation and an
increase in engine speed without an increase in pressure
or flow. If an air leak is suspected, discontinue pumping
and isolate problem. Cavitation can also occur with large
nozzle tips. Solve this problem by reducing flow. Failure
to comply may result in damage to water pump.
(11) Remove cap (6) from NO. 1 DRIVER SIDE DISCHARGE (7).
