Engine Oil Recommendation
Multi-viscosity oils are recommended. SAE 10W30 is recommended for your engine from 0 degrees F (-18 degrees C)
or above. If ambient temperatures are consistently below 0 degrees F, SAE 5W30 oil can be used. Synthetic oils are
not recommended for industrial or stationary engines.
Oil Filter
The PSI GM Powertrain engines use an AC Delco oil filter as original equipment. An equivalent oil filter must be used
when servicing the engine (see Engine Specifications 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 oil filter gasket. Tighten as necessary to stop any oil leakage
noted.
Engine Air Cleaner
The engine air cleaner filters air entering the engine intake system and acts as a silencer and flame arrester when
assembled to the intake system.
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 shorten engine
life.
A restricted or dirty air cleaner will also cause a rich fuel mixture. Thus, it is extremely important that the air cleaner be
serviced properly at the recommended intervals.
CAUTION: Service the air cleaner more frequently under severe dusty or dirty conditions.
Remove the primary air cleaner element from the air cleaner assembly and inspect the element for foreign material
restrictions or signs of excessive wear or damage. Replace the element if necessary.
Remove all dust and foreign matter from the air cleaner housing.
Reinstall the air cleaner element. Reinstall the air cleaner cup, and securely fasten the retaining clips.
Safety Element
If your engine is equipped with an air cleaner which utilizes a safety element, ensure that the element is properly in
place before installing the primary element. Change the safety element annually.
COOLING SYSTEM MAINTENANCE
Coolant Level
Check the coolant level of the radiator daily and only when the engine is cool. Generally a good time to do this is just
prior to starting the engine for the first time each day.
Maintain the coolant level at ¾ to 1½ inches below the filler neck seat of the radiator when the coolant is cold. When
ever coolant level checks are made inspect the condition of the radiator cap rubber seal. Make sure it is clean and free
of any dirt particles which would keep it from seating on the filler neck seat. Rinse off with clean water if necessary.
Also make sure that the filler neck seat is free of any dirt particles.
Caution: Never remove the radiator cap under any conditions while the engine is operating. Failure to follow
these instruction could result in damage to the cooling system, engine, or cause personal injury. To avoid
having scalding hot coolant or steam blow out of the radiator, use extreme caution when removing the
radiator cap from a hot radiator. If possible, wait until the engine has cooled, then wrap a thick cloth around
the radiator cap and turn slowly to the first stop. Step back while the pressure is released from the cooling
system. When all the pressure has been released, press down on the cap and remove it slowly.
Notice: DO NOT add coolant to any engine that has become overheated until the engine cools. Adding coolant to an
extremely hot engine can result in a cracked block or cylinder head.
