The water pump installed on the front of a 1984 Ford Ranger circulates coolant between the radiator and the engine, making sure that the coolant flows smoothly between the two. When the water pump goes out, the engine can potentially overheat, which can potentially damage the engine beyond repair. The fix is to remove the water pump and replace it with a new one, which can be done in about an hour with the right tools. First though, you have to remove the old water pump.
Tools Used: 3/8-inch ratchet and socket set, Open-end wrench set, Flathead screwdriver, Drain pan
