How to Replace the Water Pump in a 2003 Dodge Grand Caravan

The Dodge Caravan is a family minivan made by Chrysler since 1984. The Grand Caravan has a longer wheelbase than the Caravan and most often has a 6-cylinder, 3.3-liter engine. The water pump in the 2003 Dodge Grand Caravan is attached to the front of the engine and receives power from the engine with a belt and pulley. The replacement of the water pump in this vehicle also requires you to drain the radiator.

Instructions

1

Allow the engine to cool completely to ensure the coolant will not cause injury. Remove the negative battery cable with a socket wrench to prevent anyone from starting the engine inadvertently.

2

Place a drain pan beneath the drain hole for the radiator. Remove the radiator drain plug to drain the coolant into the drain pan. Replace the radiator drain plug.

3

Disconnect the right splash shield from the engine with a socket wrench and remove the accessory drive belt. Unfasten the mounting bolts for the water pump pulley and position the pulley between the drive hub and the water pump. Remove the mounting bolts for the water pump and detach the water pump from the engine.

4

Install a new seal into the housing groove on the new water pump. Mount the new water pump to the engine and torque the mounting bolts to 105 in.-lbs. with a torque wrench. Fasten the mounting bolts for the water pump pulley and tighten them to 250 in.-lbs. Turn the water pump manually to ensure it rotates freely.

5

Install the accessory drive belt and right splash shield for the engine. Connect the cable for the negative battery terminal with a socket wrench. Fill the radiator with coolant and start the engine. Check and correct any leaks in the cooling system.
