How to Replace Water Pump on Stratus, Avenger and Sebring?

The Complete Procedure to replace Water Pump.

Please Note that this Procedure Covers all 1999 to 2005 Chrysler/Dodge Avenger, Chrysler Sebring Coupe and Dodge Stratus/ Stratus Coupe models.

The water pump replacing is for
2.0L and 2.4L Engines.
2.5L Engine.
And
2.7L & 3.0L Engine models.

2.0L And 2.4L Engines

This engine uses a die-cast aluminum body water pump with a stamped steel impeller. The water pump bolts directly to the block. Cylinder block-to-water pump sealing is provided by a large rubber O-ring. The water pump is driven by the timing belt, that must be removed to service the water pump.

1. Disconnect the negative battery cable from the left shock tower.
   
   NOTE

   The ground cable is equipped with an insulator grommet which should be placed on the stud to prevent the negative battery cable from accidentally grounding.
   
   
   
   NOTE

   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 Top Dead Center (TDC) on No. 1 compression stroke. This should align all timing marks on the crankshaft sprocket and both camshaft sprockets.
2. Drain the cooling system.
3. Remove or disconnect the following: 
   
   NOTE

   Do not disconnect the power steering fluid lines.
   
   
   
   WARNING

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

   Do not allow the camshafts to turn when the camshaft sprockets are being removed.

   Fig. When installing the water pump, properly Install the O-ring to ensure a tight seal-2.0L and 2.4L engines

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, damaged impeller or sprocket or sprocket flange loose or damaged.
2. Install or connect the following:
   
   WARNING

   Be 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.
   
   
   
   New rubber O-ring into the water pump
   Water pump. Torque the bolts to 105 inch lbs. (12 Nm)
3. Pressurize the cooling system to 15 psi (103.4 kPa) and check for leaks. If okay, release the pressure and continue the engine assembly process.
4. Install or connect the following:
   
   NOTE

   DO NOT allow the camshafts to turn while the sprocket bolts are being tightened to maintain timing mark alignment.
   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.

   Accessory drive belts. Properly tension the drive belts
5. Refill and bleed the cooling system.
6. Start the engine and check for proper operation.
7. Check and top off cooling system, if necessary.

2.5L Engine

This procedure requires removing the timing belt and auto-tensioner. Set the engine at Top Dead Center (TDC) on the No. 1 cylinder compression stroke. This should align all timing marks on the crankshaft sprocket and both camshaft sprockets.

The water pump bolts directly to the engine block using a gasket for pump-to-block sealing. The pump is serviced as a unit. The 2.5L engine uses metal piping beyond the lower radiator hose to route coolant to the suction side of the water pump, located in the -V- of the cylinder banks. These pipes also have connections for thermostat bypass and heater return coolant hoses. The pipes use O-rings for sealing.

The water pump is driven by the timing belt which must be removed to service the water pump. Timing belt covers must be removed to access the timing belt.

1. Disconnect battery negative cable from remote negative terminal on shock tower and properly isolate to prevent accidental reconnection.
   
   CAUTION

   This operation must only be performed on a cold engine.
2. Drain the engine coolant.
3. Remove or disconnect the following:
   
   
   Negative battery cable

   Accessory drive belts and crankshaft damper

   Support the engine and remove the right engine mount

   Timing belt covers

   Timing belt and tensioner

   Water pump mounting bolts

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 bearing. Any problems require a new pump.
2. Install or connect the following:
   
   WARNING

   Wet the O-ring with water to make installation easier; DO NOT use oil or grease.
   NOTE

   Fit the pump inlet opening over the water pipe and press the assembly together to force the pipe into the water pump.

   Crankshaft damper

   Accessory drive belts and adjust tension

   Negative battery cable
3. Fill and bleed the engine cooling system.
4. Start the engine and verify proper operation.
