a) Or every two years, whichever
comes first.
b) 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.
c) Or every four years, whichever
comes first.
d) Do not directly power wash
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.
e) Or every five years, whichever
comes first. See Cooling System on
page 10 14.
f) Or every 10 years, whichever
comes first. Inspect for fraying,
excessive cracking, or damage;
replace, if needed.
