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 the Engine Specification on page 32 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.
ENGINE FLAME ARRESTOR
CAUTION:
Service the flame arrestor more frequently under severely
dusty or dirty conditions.
Your flame arrestor filters air entering the engine induction system and acts as a
silencer. Air that contains dirt and grit produces an abrasive fuel mixture and can
cause 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 will also cause a rich fuel mixture.
Therefore it is extremely important that the flame arrestor be serviced at the
recommended intervals.
1. Clean screen by washing with solvent.
2. Blow dry or allow to drip dry prior to installation
3. Remove all dust and foreign matter from spark arrestor
4. Make sure the flame arrestor is seated properly on the throttle body and
secured with the proper clamp when reinstalling.
