How to Change a Water Pump on Cars

by Contributing Writer; Updated June 12, 2017

Changing the water pump on your Plymouth car is easy enough that you can do it yourself and save a lot of money on labor charges at a repair shop. Signs that your water pump is bad could be the car overheating, or you see leakage around the water pump bearing where the pulley is located. The most difficult part of this project is the fact that you have to crawl under the car to get to it, unlike most other vehicles where you can access the water pump from the engine compartment. The project will take you about two hours to complete.

Under The Hood:

 How to Change a Water Pump on a PT Cruiser

Take the PT Cruiser to a certified air conditioning repair shop. Have them evacuate the freon. Explain that you are doing a water pump, and ask them if they will "hold" the freon for you until you finish changing the water pump. Ask them up front how much it will be to remove the freon and refill the air conditioning system.

Slide the drain pan under the petcock on the radiator. Loosen the petcock and allow the coolant to drain. Discard the coolant in an appropriate manner if it is dirty or more than five years old. If the coolant is clean and is less than five years old, you can reuse the coolant.

Raise the front of the vehicle with a floor jack, and support it with jack stands. Remove the right front wheel, using the lug wrench. Remove the right, inner splashguard. Loosen the accessory drive belt tensioners and remove the accessory drive belts. Using a socket, remove the crankshaft pulley bolt.

Remove the crankshaft pulley using tools 1026 and 6827-A. Disconnect the exhaust system from the manifold, using the appropriate sockets. Unplug the air compressor pressure switch wiring harness. Disconnect the air compressor pipes from the connector block on the back of the air compressor.

Slide the floor jack under the engine and jack it up until it touches the bottom of the engine. Remove the lower torque strut, right engine mount, right engine mount bracket, upper torque strut and the upper torque strut bracket, using the appropriate sockets.

Unbolt and remove the power steering pump and its bracket, but do not remove the lines on the back of the pump. Lay the pump out of the way. Unbolt and remove both timing belt covers, using the appropriate sockets and wrenches.

Turn the crankshaft clockwise until the timing mark on the crankshaft is at the 1 o'clock position, and the timing mark on the right camshaft (as you are looking down at the engine) is at the 9 o'clock position. The arrows and "UP" marks on the camshaft sprockets should also be facing up.

Push a 1/8-inch Allen wrench into the tensioner pulley, then use a 6-mm Allen wrench to turn the tensioner counterclockwise until it locks into position. Remove the Allen wrench, then lift the timing belt off the pulleys.

Remove the camshaft sprockets using the appropriate sockets. Remove the rear timing belt cover using the appropriate sockets. Unbolt and remove the water pump. Pull the O-ring off the block, if it sticks to it. Clean the water pump mounting surface of all gasket material.

Coat the new O-ring with dielectric grease. Press the O-ring into the water pump, making sure it is properly seated in its groove. Install the water pump and tighten the bolts by hand. Turn the water pump pulley to ensure that there is no resistance. Tighten the water pump bolts to 105 in.-lbs. of torque.

Reinstall the rear timing belt cover and the camshaft sprockets, ensuring that the "UP" marks are in position and that the timing marks are lined up. Turn the crankshaft sprockets clockwise until the timing marks are 1/2 tooth apart.

Install the timing belt -- it's best to replace the timing belt, unless it is less than two years old -- on the sprockets and pulleys, starting with the crankshaft pulley and working counterclockwise. Route the belt over the water pump, behind the idler pulley and over the top of the camshafts, keeping the belt taut on that side. Route the belt down behind the tensioner pulley.

Turn the camshaft sprockets until the mark on the right camshaft is at the 9 o'clock position. Remove the Allen wrench from the tensioner and allow the tensioner to put tension on the belt. Turn the crankshaft slowly, two turns, until the timing marks are lined up again.
