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 silicone applied.

- Verify the retaining bolts and bolt holes have clean threads. Re-tap or chase the threads as necessary.




- To simplify the gasket installation process and minimize errors, install the gasket as follows:
1. Verify the gasket is correct.
2. Apply the sealant to the pump sealing surface and the gasket inner surface. Apply only a light film of sealant to the sealing surfaces.

CAUTION: Excess sealant will squeeze out on the inside of the pump and may block the radiator or heater core coolant passages.

3. Install two retaining bolts through the pump.

NOTE: This will help maintain the correct alignment of gasket in the next step.

4. While holding the bolts, place the gasket over the bolts and onto the pump sealing surface.
5. Install the pump and gasket onto the engine.

- 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.
