Water Pump

Print

REMOVAL & INSTALLATION



The water pump is driven by the timing belt from the crankshaft. It is good practice to turn the engine crankshaft by hand (clockwise) to set the engine to Top Dead Center (TDC) for the No. 1 cylinder compression stroke (firing position) before starting work. This should align all timing marks and serve as a reference point for later work.

2.0L and 2.4L Engines

See Figures 1 and 2

  1. Disconnect the negative battery cable.
  2.  

This procedure requires removing the engine timing belt and the auto tensioner. The factory specifies that the timing marks should always be aligned before removing the timing belt. Set the engine at TDC on No. 1 compression stroke. This should align all timing marks on the crankshaft sprocket and both camshaft sprockets.

  1. Raise and safely support the vehicle to a level that allows access from above and below.
  2.  
  3. Remove the right inner splash shield.
  4.  
  5. Remove the accessory drive belts.
  6.  
  7. Place a drain pan under the radiator drain plug. Drain and properly contain the cooling system.
  8.  
  9. Support the engine using a floor jack and block of wood, then remove the right motor mount.
  10.  
  11. Remove the timing belt, tensioner and camshaft sprockets.
  12.  


WARNING
With the timing belt removed, DO NOT rotate the camshaft or crankshaft, or damage to the engine could occur.

  1. Remove the rear timing belt cover to access the water pump.
  2.  
  3. Remove the water pump attaching bolts.
  4.  
  5. Remove the water pump.
  6.

To install:
  1. Thoroughly clean all sealing surfaces. Replace the water pump if there are any cracks, signs of coolant leakage from the shaft seal, loose or rough turning bearings, a damaged impeller or sprocket, or a loose or damaged sprocket flange.
  2.  
  3. Install a new rubber O-ring into the water pump.
  4.  

Make sure the O-ring is properly seated in the water pump groove before tightening the screws. An improperly located O-ring may cause damage to the O-ring and cause a coolant leak.

  1. Install the water pump and tighten the bolts to 105 inch lbs. (12 Nm).
  2.  
  3. Using a cooling system pressure tester, pressurize the cooling system to 15 psi and check for leaks. If okay, release the pressure and continue the engine assembly process.
  4.  
  5. Rotate the water pump by hand to check for freedom of movement.
  6.  
  7. Install the rear timing belt cover.
  8.  
  9. Install the camshaft sprocket(s), timing belt and tensioner. DO NOT allow the camshafts to turn while the sprocket bolts are being tightened, in order to maintain timing mark alignment.
  10.  


WARNING
Do not attempt to compress the tensioner plunger with the tensioner assembly installed in the engine. This will cause damage to the tensioner and other related components. The tensioner MUST be compressed in a vise.

  1. Install the timing belt covers.
  2.  
  3. Install the right engine mount bracket and engine mount.
  4.  
  5. Remove the floor jack and wood block from underneath the engine.
  6.  
  7. Install the crankshaft damper.
  8.  
  9. Install the right inner splash shield.
  10.  
  11. Lower the vehicle.
  12.  
  13. Install and tension the accessory drive belts.
  14.  
  15. Refill the cooling system using the correct quantity and type of coolant. Bleed the cooling system.
  16.  
  17. Start the engine and check for proper operation.
  18.  
  19. Check and top off the cooling system, if necessary.
  20.  

2.5L Engine

See Figures 3 through 7

  1. Disconnect the negative battery cable.
  2.  
  3. Place a large drain pan under the radiator drain plug. Drain and properly contain the engine coolant.
  4.  

This procedure requires removing the engine timing belt and the auto tensioner. To help assure proper alignment at assembly, it may be helpful to set the engine at TDC on No. 1 compression stroke. This should align all timing marks on the crankshaft sprocket and both camshaft sprockets.

  1. Remove the accessory drive belts and crankshaft damper.
  2.  
  3. Remove the right engine mount. This requires safely supporting the engine with a floor jack and wood block so the mount can be removed.
  4.  
  5. Remove the timing belt covers.
  6.  
  7. Remove the timing belt and tensioner.
  8.

  1. Remove the water pump mounting bolts.
  2.  
  3. Separate the water pump from the water inlet pipe and remove the pump.
  4.  

To install:
  1. Thoroughly clean all sealing surfaces. Inspect the pump for damage or cracks, signs of coolant leakage at the vent, and excessive looseness or rough turning bearings. Any problems require a new pump.
  2.  
  3. Install a new O-ring on the water inlet pipe. Wet the O-ring with water to make installation easier. DO NOT use oil or grease on the O-ring.
  4.  
  5. Install a new gasket on the water pump and fit the pump inlet opening over the water pipe. Press the assembly together to force the pipe into the water pump.
  6.  
  7. Install the water pump-to-engine bolts and tighten to 20 ft. lbs. (27 Nm).
  8.  
  9. Install the timing belt and timing belt tensioner. Set the timing belt tension.
  10.  
  11. Install the timing belt covers. Install the right engine mount. Remove the floor jack and engine block from underneath the engine.
  12.  
  13. Install the crankshaft damper.
  14.  
  15. Install the accessory drive belts and set to the proper tension.
  16.  
  17. Connect the negative battery cable.
  18.  
  19. Fill and bleed the engine cooling system.
  20.  
  21. Start the engine and verify proper operation, with no leaks.
