PSI Operators Manual
Plain water may be used in an emergency (except in freezing temperatures), but replace it with the specifi ed
coolant as quickly as possible to avoid damage to the system.
Radiator
Inspect the exterior of the radiator for obstructions. Remove all bugs, dirt or foreign material with a soft brush
or cloth. Use care to avoid damaging the core fi ns. If available, use low pressure compressed air or a stream of
water in the opposite direction of the normal air fl ow. Check all hoses and connections for leaks. If any of the
hoses are cracked, frayed, or feel spongy, they must be replaced.
Fan Belts
The water pump is usually belt driven. The same belt may also drive the fan and/or the alternator. The drive
belts should be properly adjusted at all times. A loose belt can cause improper alternator, fan and water pump
operation, in addition to overheating.
Serpentine Belt
Some GM Powertrain engines utilize serpentine belts on the front of the engine. This type of belt system incor-
porates a belt tensioning device which keeps the belt at the proper tension.
This belt should be checked routinely for cracks or ‘checking’ on the groove side of the belt. If cracks or ‘check-
ing’ are apparent the belt must be changed.
V-Type Belt
V-Type belts are generally tensioned by adjusting the alternator, or through a mechanical belt tensioner. The belt
is generally correctly tensioned when there is an ½ inch of depression on the belt between the water pump and
the crankshaft pulley.
Fuel Filter
Fuel Injected Engines
On some PSI Fuel Injection or Fuel Injection/Dual Fuel as many as two fuel fi lters may be used in the gaso-
line fuel supply line to the engine. A coarse fuel fi lter may be located in the supply line between the fuel tank
and the electric fuel pump. This fi lter protects the fuel pump from debris in the fuel tank. This fi lter must be
changed every 200 hours or every 6 months which ever occurs fi rst.
A primary fuel fi lter is located between the fuel pump and the engine. This fi lter protects the injectors from
microscopic particles in the fuel which can cause plugging of the injectors. This fi lter MUST be changed every
500 hours or annually which ever occurs fi rst.
CAUTION: Failure to change the fuel system fi lters as recommended can result in premature failure of the fuel
system components.
