Installation Instructions
! WARNING
When working on air system components the following precautions should be
observed.
1. Stop the engine when working under a vehicle. Always block the vehicle
wheels to prevent a fore or aft roll. Bleeding off system pressure may cause the
vehicle to roll. Keep hands away from brake chamber push rods and brake
adjusters; they may apply as system pressure drops.
2. Never connect or disconnect a hose or line containing air pressure. It may whip
as air escapes. Never remove a component or a pipe plug unless you are certain
all system air pressure has been exhausted.
3. Never exceed recommended working air pressure and always wear safety
glasses when working with pressurized air. Never look directly into component
ports or direct a pressurized air flow at anyone.
4. Never attempt to disassemble a component until you have read and understood
all recommended procedures. Some components contain powerful springs and
injury can result if not properly disassembled. Use only proper tools and observe all
precautions pertaining to the use of those tools.
INSTALLATION INSTRUCTIONS
1. Handle your water pump with care. If the unit is dropped, you could damage the
shaft, bearing, housing or the internal seal.
2. Drain and flush your cooling system. Check your fan belts, thermostat, radiator
cap, fan, fan clutch and pulleys. (If you are replacing a Cummins suitcase style
water pump, the idler should be replaced at the same time.)
3. Clean the water pump surface area on the engine (the area must be clean and
free of dirt or grease). Install your water pump using a staggered sequence when
tightening the bolts. Once you have your water pump in place and all bolts are
tightened, turn the pump shaft by hand. The pump should rotate freely. If it does
not, you may have to remove the water pump and begin again.
4. Install your fan belts and check belt tension. You should have 1/2" to 3/4" of
deflection. If a fan belt is too tight, it could damage your engine. (See Warranty
Information)
