Water Pump: Fundamentals and Basics
Installation Tips and Hints
WATER PUMP INSTALLATION NOTES
-
Compare the old pump to the new pump and verify:
-
Shaft lengths match exactly.
-
Retaining bolt holes match exactly.
-
Prior to applying the sealant to the gasket and pump, practice installing the pump to the engine. If any problems are encountered they will be easier
to solve without the sealant applied.
-
Verify the retaining bolts and bolt holes have clean threads. Re-tap or chase the threads as necessary.
-
Do not over tighten the retaining bolts, use a torque wrench to properly tighten the bolts to the correct specification.
CAUTION: Water pump retaining bolts may be easily broken or stripped, do not tighten the retaining bolts with an air wrench or impact gun.
-
When tightening hose clamps:
-
Position the hose squarely on the fitting.
-
Verify the hose clamp is clear of the retaining rim on the fitting. Do not over tighten the clamps.
-
While working on the cooling system it is a good habit to clean the radiator and A/C condenser fins of bugs and dirt. This build up of debris can
seriously reduce the cooling ability of the system.
