Pumps are engineered and manufactured by PRW Industries, Inc. to maximize efficiency for many popular

GENERAL INSTALLATION PROCEDURE
Step 1 - Cool Engine
Step 2 - Disconnect battery
Step 3 - Drain all coolant from the entire cooling system and engine cavity. Dispose of the coolant
according to EPA regulations.
Step 4 - Check the hoses, and radiator. If there are any signs of leakage or other problems replace or
repair. This will help prevent future trouble.
Step 5 - Remove the belts and fan. If there are any signs of wear replace.
Step 6 - Loosen the bolts and remove the old water pump.
Step 7 - Clean the engine block’s mounting surface area by removing any gasket or sealant deposits, and
any other residue.
Step 8 - Position new gaskets on water pump housing, using sealer on both sides. Make sure the gasket
matches the surface being sealed.
Step 9 - Carefully install the new PRW water pump. Do not strike the shaft! Hand - tighten the water
pump bolts into the block. Give the pump a quick spin to check for free operation.
Step 10 - Torque the bolts to OEM specifications using a crisscross pattern. Over tightened bolts could
damage the pump and void the warranty.
Step 11 - Hand-turn the pump again to make sure that it turns freely.
Step 12 - Inspect the radiator cap and thermostat. Replace, if they show any signs of sticking or leaking.
Step 13 - Reconnect the hoses using new clamps and sealant. Refer to the owner’s manual for any special
procedures.
Step 14 - Verify that the hoses are clear of all moving parts and that the clamps do not contact the pulleys,
brackets, and/or the fan.
Step 15 - Refill the cooling system and check for any leaks.
Step 16 - If a pulley is to be installed, mount it square on the pumps hub. Using lock washers, torque the
bolts to OEM specifications to insure against wobble-free operation.
Step 17 - Reinstall fan and spin by hand and inspect for any wobble. Maximum wobble should be 3/32”
at the outer edge if no clutch, and 0.250” with a clutch. Replace any fan clutch with excessive wobble,
looseness, or loss of oil. A misaligned or defective clutch will damage the water pump. Check the fan
blade tip clearances to the radiator and any shroud.
Step 18 - Check any electric cooling fan to insure it is working properly.
