How do you replace the water pump on a 1995 Geo Metro?

Answer 1

The water pump for the 1995 Geo Metro is a little above and in front of the alternator. It is also bracketed behind the timing belt. So if you do not know how to or do not have the tools to work with anything involving the timing belt, I would recommend that you take your vehicle to a professional.

Removal of water pump:

1. Disconnect the negative battery cable

2. Drain the cooling system.

a. WARNING: Drain into a closable container so as not to poison your surroundings and pets.

3. Remove the air cleaner assembly.

4. Loosen but do not remove the 4 water pump pulley bolts.

5. Raise and support the vehicle.

6. Remove the lower splash shield.

7. Remove the AC compressor drive belt.

8. Remove the lower alternator cover plate bolts.

9. Loosen the alternator adjusting bolt

10. Remove the drive belt.

11. Remove the crankshaft pulley.

12. Remove the water pump pulley.

13. Remove the timing belt.

14. Remove the oil level dipstick and guide tube.

15. Remove the alternator adjusting bracket from the water pump.

16. Remove the water pump rubber seals.

17. Remove the water pump mounting bolts and nuts.

18. Remove the water pump from the vehicle.

Installation: Pretty much use removal instructions but go backwards. I'll list bolt tightening in order that they should appear.

b. Install the pump using a new gasket and tighten bolts to 115 inch lbs

3. Install new rubber seals.

5. When you get to the alternator cover plate and the bolts tighten to 89 inch lbs.

6. When you get to the water pump pulley mounting bolts tighten to 18 ft lbs
