How do you replace a water pump on 01 maxima?

Answer 1

1. Disconnect negative battery cable
2. Drain cooling system
3. Remove the drivebelt idler pulley bracket and the right side engine mount and brackets.Also remove the main timing chain tensioner cover and the water pump cover from the front timing chain cover.Press the timing chain tensioner piston inward and insert an appropriate size pin into the tensioner hole to lock the tensioner in place.Rotate the crankshaft 20 degrees counterclockwise to loosen the chain around the water pump sprocket.
4. Remove the bolts and detach the water pump from the engine.Check the impelleron the backside for evidence of corrosion or missing fans.
5. Clean the bolt threads and the threaded holes in the engine to remove corrosion and sealant.
6. Compare the new pump with the old pump to make sure they're identical.
7. Remove all traces of old gasket sealantfrom the engine.
8. Clean the engine and new water pump mating surfaces with lacquer thinner or acetone.
9. Carefully attach the pump to the engine and thread the bolts into the holes finger tight.Use a small amount of RTV sealant on the bolt threads =, and make sure that the dowel pins, if used, are in their original locations.
10. Torque the bolts to 61-86lbs in 1/4-turn increments.Dont over tighten the bolts or the pump may be disorted.Rotate the crankshaft 20 degrees clockwise to tighten the timing chain around the water pump sprocket.

Remove the stopper pin from the timing chain tensioner and install the

tensioner cover and water pump access cover after cleaning them and

applying RTV sealantto them.

11. Reinstall all parts removed for access tot he pump.

12. Refill and bleed the cooling system and check the drivebelt tension.Run the

engine and chack for leaks.
