The water pump mounted to the front of a 1993 Dodge Dakota circulates the coolant from the radiator throughout the engine block, cooling down the engine in the process. When the water pump goes out, the engine won’t cool, and it could overheat, causing severe damage to the engine. To fix the problem, you have to remove the water pump and replace it with a new one. Replacing the water pump is not a complicated job, and it can be done at home with a few basic tools.
Tools Used: Tools, Drain pan, 3/8-inch ratchet and socket set, Flat-head screwdriver
Remove Water Pump
Allow the engine to cool for several hours before you work on the cooling system. The coolant inside is very hot, and you risk burning yourself otherwise. Pop the hood and remove the radiator cap. Place the drain pan underneath the radiator and open the petcock at the base. Drain the radiator of coolant. Unbolt the air conditioning compressor from the top of the engine using the 3/8-inch ratchet and socket. Push it towards the engine to release the belt from the pulley, then move the compressor out of the way, resting on top of the engine.
Loosen the alternator bolts from the engine using the ratchet and push the alternator towards the engine block with your hands. Pull the belt off the alternator pulley. Disconnect the hose clamps on the hoses connected to the water pump using the flat-head screwdriver. Pull the hoses off the water pump. Unbolt the water pump from the engine using the 3/8-inch ratchet and socket. Pull the water pump off the engine using your hands.
Tips & Warnings: Never work on the cooling system of a hot engine or you risk serious burns or injury.
