Oil Filter
NOTE: Ensure the old filter gasket is removed prior to installing the new
filter.
The Kodiak GM Powertrain engines use an AC Delco (or equivalent) oil filter as
original equipment. An equivalent oil filter must be used when servicing the engine
(see Engine Specifications starting on page 20 for the recommended oil filter for
your engine).
The filter protects your engine from harmful, abrasive, or sludgy particles without
blocking the flow of oil to vital engine parts.
To replace the filter, use a proper filter wrench to remove the filter. Clean the filter-
mounting base and lightly coat the gasket surface of the new filter with engine oil.
Hand tighten the filter until the gasket contacts the base, then tighten another ½
turn. Fill the engine with the correct amount of oil, run the engine and check for oil
leaks at the drain plug and filter gasket. Tighten as necessary to stop any oil
leakage.
FLAME ARRESTER
The purpose of the flame arrestor is to contain any possible flame that gets into the
intake manifold due to an engine failure, but also serves other purposes.
CAUTION: Service the flame arrestor more frequently under severely
dusty or dirty conditions.
Your flame arrestor does not filter the air entering the engine induction system but
does act as a silencer. The flame arrester is not
an actual air filter. Air that
contains dirt and grit produces an abrasive fuel mixture and can causes severe
damage to the cylinder walls and piston rings. Damage to the cylinder walls and
piston rings will cause high oil consumption and short engine life. A restricted or
dirty flame arrestor can cause a low power situation. Therefore it is extremely
important that the flame arrestor be serviced at the recommended 100 hr intervals,
or sooner depending on operating conditions.
1. Clean screen by washing with solvent.
2. Blow dry or allow dripping dry prior to installation.
3. Remove all dust and foreign matter from spark arrestor.
Make sure the flame arrestor is seated properly on the throttle body when
reinstalled. Do not operate engine without flame arrestor.
