   Water Pump
   

You're right. it could very well be your water pump, but I would suggest replacing your thermostat before trying to tackle replacing your water pump. However, if your thermostat turns out not to be the problem, I have enclosed step-by-step instructions for removal and re-installation of your water pump. Hope this proves to be helpful. Have a nice evening!


1993 Geo Prism Water Pump Removal/Installation

1. Disconnect the negative battery cable. Drain the engine coolant from the radiator.
2. Remove all drive belts.
3. Support the engine using suitable equipment. Place a wooden block between the jack and engine. Remove the right engine mount and insulator.
4. Remove the No. 3 (upper) and No. 2 (middle) timing belt covers.
5. If equipped with power steering, raise and safely support the vehicle. Remove the front transaxle mount. Lower the vehicle, remove the cooling fan assembly.
6. Remove the mounting bolt for the dipstick tube; remove the tube and dipstick. Immediately plug the hole in the block to prevent fluid from contaminating the oil.
7. Remove the electrical connector for the coolant temperature sending unit.
8. Remove the 2 nuts securing the engine coolant pipe to the cylinder block.
9. Loosen the hose clamp and remove the coolant inlet pipe from the vehicle.
10. Loosen the hose clamp and remove the coolant inlet hose from the water pump.
11. If equipped with power steering, raise the engine and remove the mounting bolts for the water pump. Remove the water pump and O-ring from the vehicle.

To install:

1. Install a NEW O-ring to the vehicle. Install the water pump and torque the retaining bolts EVENLY to 11 ft. lbs.
2. Lower the engine if necessary, and connect the coolant hose to the water pump. Reconnect the engine coolant inlet pipe to the vehicle and secure to hose with clamp and secure to block with 2 nuts. Tighten the engine coolant inlet pipe nuts to 11 ft. lbs.
3. Connect the electrical connector for the coolant temperature sending unit.
4. Install the oil guide tube and torque the retaining bolt to 84 inch lbs. Install the oil level indicator to the guide tube.
5. Install the radiator fan assembly, if necessary.
6. If equipped with power steering, raise and safely support the vehicle. Install the front transaxle mount. Torque the through bolt nut to 64 ft. lbs. and 2 mount nuts to 47 ft. lbs.
7. Lower the vehicle (if necessary) and install the No. 3 (upper) and No. 2 (middle) timing belt covers.
8. Support the engine using suitable equipment. Install the right engine mount and insulator.
9. Remove all engine lifting equipment.
10. Install and adjust all drive belts.
11. Reconnect the negative battery cable. Fill the cooling system. Start the engine and check for coolant leaks.

1. Let me know if you cannot see diagrams(happens sometimes) or if you have any questions

Just to make sure. I assume that you are seeing coolant leakage from around the water pump assembly.

1. 
   
2. Disconnect the negative battery cable.
3. Place fender covers on the aprons.
4. Drain the cooling system.
5. Remove the accessory drive belts.
6. Remove the timing belt cover.
7. Use a wrench on the crankshaft pulley to rotate the engine so No. 1 piston is on TDC of the compression stroke.

Turn the engine only in the direction of normal rotation. Backward rotation will cause the timing belt to slip or lose teeth.

1. Loosen the belt tensioner attaching bolts, then secure the tensioner over as far as possible.
2. Pull the belt from the camshaft, tensioner, and water pump sprocket. Do not remove it from, or allow it to change its position on, the crankshaft sprocket.

WARNINGDo not rotate the engine with the timing belt removed or serious engine damage could occur. The 1.3L and 1.6L engines are of the "interference type," meaning it is possible for the valves to contact the pistons if their reciprocation is not carefully timed and controlled. An engine allowed to spin freely without the timing belt could bend valves and scuff pistons almost instantly.

1. Remove the camshaft sprocket.
2. Remove the rear timing cover stud.
3. Remove the heater return tube hose connection at the water pump inlet tube.
4. Remove the water pump inlet tube fasteners and the inlet tube and gasket.
5. Unfasten the water pump to the cylinder block bolts and remove the water pump and its gasket.

Fig. 6: ... and carefully clean both of the water pump mating surfaces using a gasket scraperTo install:

1. Make sure the mating surfaces on the pump and the block are clean.
2. Using a new gasket and sealer, install the water pump. Tighten the bolts to 30-40 ft. lbs. (40-55 Nm) on 1981-87 models, or to 15-22 ft. lbs. (20-30 Nm) on 1988-90 models. Make sure the pump impeller is able to turn freely.
3. Install the water pump inlet tube and the inlet tube gasket and fasteners.
4. Install the rear timing cover stud. Install the heater return tube hose connection at the water pump inlet tube.
5. Install the camshaft sprocket.
6. Install the belt from the camshaft, timing belt tensioner, and water pump sprocket.

1. Tighten the belt tensioner attaching bolts, then secure the tensioner over as far as possible.
2. Install the timing belt cover.
3. Install the accessory drive belts.
4. Refill the cooling system and reconnect the negative battery cable.
