Vacuum crankcase ventilation
hoses
Inspect the surface of hoses for evi -
dence of heat and/or mechanical dam -
age. Hard and brittle rubber, cracking,
tears, cuts, abrasions, and excessive
swelling indicate deterioration. Particular
attention should be paid to examine
those hose surfaces nearest to high heat
sources, such as the exhaust manifold.
Inspect the hose routing to assure that
the hoses do not come in contact with
any heat source, sharp edges or moving
components which might cause heat
damage or mechanical wear. Inspect all
hose connections, such as clamps and
couplings, to make sure they are secure,
and that no leaks are present. Hoses
should be replaced immediately if there
is any evidence of deterioration or dam
-
age.
