Tools Needed:
- Socket set
- Ratchet
- Pliers
- Screwdriver
- Drain pan
- Funnel
- New water pump
- Gasket
Instructions:
1. Before you begin, make sure the engine is cool and the vehicle is parked on a level surface. Engage the parking brake and chock the wheels to prevent the vehicle from rolling.
2. Locate the water pump on the front of the engine. It is typically located below the thermostat housing.
3. Drain the coolant from the radiator. Place a drain pan under the radiator and loosen the drain plug. Allow the coolant to drain completely.
4. Remove the serpentine belt. Use a ratchet to loosen the tensioner pulley and then slip the belt off of the pulleys.
5. Remove the water pump bolts. There are typically four bolts that hold the water pump in place. Use a socket set to loosen the bolts and then remove them.
6. Remove the old water pump. Once the bolts are removed, you can gently pry the water pump off of the engine block. Be careful not to damage the gasket.
7. Clean the mating surface of the engine block. Use a scraper to remove any old gasket material from the engine block. Make sure the surface is clean and smooth before installing the new water pump.
8. Install the new gasket. Place the new gasket on the mating surface of the engine block. Make sure the gasket is seated properly and that there are no gaps.
9. Install the new water pump. Carefully lower the new water pump into place and align it with the gasket. Install the bolts and tighten them until they are snug.
10. Reinstall the serpentine belt. Slip the serpentine belt back onto the pulleys and then tighten the tensioner pulley.
11. Refill the radiator with coolant. Use a funnel to add coolant to the radiator until it is full.
12. Start the engine and let it run for a few minutes. Check for any leaks around the water pump. If there are no leaks, turn off the engine and top off the coolant if necessary.
13. That's it! You have successfully replaced the water pump on your 1993 Mercury Topaz.
