Service and Maintenance 11-5
Check to be sure vent hose is
unobstructed, clear, and free of
debris. During any maintenance,
if a power washer is used to
clean mud and dirt from the
underbody, care should be taken
to not directly spray the transfer
case output seals. High pressure
water can overcome the seals
and contaminate the transfer
case fluid. Contaminated fluid
will decrease the life of the
transfer case and should
be replaced.
.Evaporative control system
inspection. Check all fuel and
vapor lines and hoses for proper
hook‐up, routing, and condition.
Check that the purge valve,
if the vehicle has one, works
properly. Replace as needed.

Protection Agency or the
California Air Resources Board

however, urge that all
recommended maintenance
services be performed at the
indicated intervals and the
maintenance be recorded.

care should be taken to not
directly spray the transfer case
output seals. High pressure water can
overcome the seals and
contaminate the transfer case
fluid. Contaminated fluid will
decrease the life of the transfer
case and should be replaced.
