How to Change the Water Pump on a 2002 Dodge Pickup Truck
- 1). Detach the negative cable from the battery and push the cable aside. Drain the coolant from the radiator. Slide a drain pan under the radiator. Open the drain plug using pliers or a wrench. If there is no plug, undo the lower radiator hose clip and pull the hose away from the radiator. Allow all the coolant to drain from the radiator.
- 2). Remove the radiator fan, the fan shroud and the wiring going to the fan. Pull the wiring plug out of the adapter.
- 3). Locate the tensioner on the serpentine belt. The belt weaves around the crankshaft pulley, the air conditioning unit, the power steering unit and the alternator. Note how the belt is routed, even draw a picture if need be, so you will know how to put it back. Loosen the tensioner and slide the belt off the pulleys.
- 4). Remove the hoses that go to the water pump. Loosen the jubilee clips with a screwdriver. Pull them off and put them aside.
- 5). Undo and remove the power steering pump unit. There are only four bolts and there is no need to remove the pipework, as this is just to provide access to the water pump. Remove the water pump and pull it out of the engine bay.
- 6). Scrape off the old gasket from the engine block. Fit new sealant to the new gasket and the new water pump. Make sure the engine block is dry. Fit the new water pump, torquing the bolts as recommended.
- 7). Refit the power steering pump unit, making sure the pipework is not twisted. Refit the serpentine belt with the correct routing and tighten the tensioner. Deflection of the belt should only be 1 to 2 mm.
- 8). Refit the radiator cooling fan, the shroud and the wiring. Close the drain plug on the radiator. Fill the radiator with the correct amount of water and coolant. Reconnect the negative cable to the battery.
