On a 1998 Cavalier 2.4L engine, is the "coolant pump" the same thing as the "water pump"? My coolant pump (under the exhaust manifold) has apparently lost a gasket and is leaking. Is there a rebuild kit or do the pump gaskets come with a cooling system kit?

Pretty sure its in between firewall and engine theres a silver pipe under exhaust manifold serp belt side is water pump ,drivers side is t stat housing,u gotta remove exhaust manifold and that crossover pipe its a fun one... cant find a good picture sorry

Check this procedure, according with the repair guide for...

2.3L and 2.4L Engines
(see Figure 9)

1. Disconnect the negative battery cable
   
2. Detach the oxygen sensor connector.
   
3. Properly drain the engine coolant into a suitable container. Remove the heater hose from the thermostat housing for more complete coolant drain.
   
4. Remove upper exhaust manifold heat shield.
   
5. Remove the bolt that attaches the exhaust manifold brace to the manifold.
   
6. Remove the lower exhaust manifold heat shield.
   
7. Break loose the manifold to exhaust pipe spring loaded bolts using a 13mm box wrench.
   
8. Raise and safely support the vehicle.
   

It is necessary to relieve the spring pressure from 1 bolt prior to removing the second bolt. If the spring pressure is not relieved, it will cause the exhaust pipe to twist and bind up the bolt as it is removed.

1. Unfasten the two radiator outlet pipe-to-water pump cover bolts.
   
2. Remove the manifold to exhaust pipe bolts from the exhaust pipe flange as follows:
   1. Unscrew either bolt clockwise 4 turns.
      
   2. Remove the other bolt.
      
   3. Remove the first bolt.
      

On the 2.4L engines, DO NOT rotate the flex coupling more than 4° or damage may occur.Pull down and back on the exhaust pipe to disengage it from the exhaust manifold bolts.

1. Remove the radiator outlet pipe from the oil pan and transaxle. If equipped with a manual transaxle, remove the exhaust manifold brace. Leave the lower radiator hose attached and pull down on the outlet pipe to remove it from the water pump. Leave the radiator outlet pipe hang.
   
2. Carefully lower the vehicle.
   
3. Unfasten the exhaust manifold-to-cylinder head retaining nuts, then remove the exhaust manifold, seals and gaskets.
   
4. For the 2.4L engine, remove the front timing chain cover and the chain tensioner. For details, please refer to the procedure located later in this section.
   
5. Unfasten the water pump-to-cylinder block bolts. Remove the water pump-to-timing chain housing nuts. Remove the water pump and cover mounting bolts and nuts. Remove the water pump and cover as an assembly, then separate the two pieces.

   2. Pump cover-to-pump assembly-106 inch lbs. (12 Nm).
      
   3. Cover-to-block, bottom bolt first-19 ft. lbs. (26 Nm).
      
   4. Radiator outlet pipe assembly-to-pump cover-125 inch lbs. (14 Nm).

6. Raise and safely support the vehicle.
   
7. Index the exhaust manifold bolts into the exhaust pipe flange.
   
8. Connect the exhaust pipe to the manifold. Install the exhaust pipe flange bolts evenly and gradually to avoid binding. Turn the bolts in until fully seated.
   
9. Connect the radiator outlet pipe to the transaxle and oil pan. Install the exhaust manifold brace, if removed.
   
10. On the 2.4L engine, install the timing chain tensioner and front cover.
    
11. Install the lower heat shield.
    
12. Carefully lower the vehicle.
    
13. Fasten the bolt that attaches the exhaust manifold brace to the manifold.
    
14. Tighten the manifold-to-exhaust pipe nuts to specification.
    
15. Install the upper heat shield.
    
16. Attach the oxygen sensor connector.
    
17. Fill the radiator with coolant until it comes out the heater hose outlet at the thermostat housing. Then connect the heater hose. Leave the radiator cap off.
    
18. Connect the negative battery cable, then start the engine. Run the vehicle until the thermostat opens, fill the radiator and recovery tank to their proper levels, then turn the engine off.
    
19. Once the vehicle has cooled, recheck the coolant level.

Water Pump REMOVAL & INSTALLATION CAUTION
Never open, service or drain the radiator or cooling system when hot; serious burns can occur from the steam and hot coolant. Also, when draining engine coolant, keep in mind that cats and dogs are attracted to ethylene glycol antifreeze and could drink any that is left in an uncovered container or in puddles on the ground. This will prove fatal in sufficient quantities. Always drain coolant into a sealable container. Coolant should be reused unless it is contaminated or is several years old. 2.4L Engine

11. Install the lower heat shield.
    
12. Carefully lower the vehicle.
    
13. Fasten the bolt that attaches the exhaust manifold brace to the manifold.
    
14. Tighten the manifold-to-exhaust pipe nuts to specification.
    
15. Install the upper heat shield.
    
16. Attach the oxygen sensor connector.
    
17. Fill the radiator with coolant until it comes out the heater hose outlet at the thermostat housing. Then connect the heater hose. Leave the radiator cap off.
    
18. Connect the negative battery cable, then start the engine. Run the vehicle until the thermostat opens, fill the radiator and recovery tank to their proper levels, then turn the engine OFF.
    
19. Once the vehicle has cooled, recheck the coolant level, then install the radiator cap.
    

3.1L Engine

1. Disconnect the negative battery cable.
   
2. Properly drain the cooling system into a suitable container.
   
3. Loosen, but do not remove, the water pump pulley bolts.
   
4. Remove the serpentine belt.
   
5. Unfasten the water pump pulley bolts, then remove the pulley.
   
6. Remove the five water pump mounting bolts, then remove the water pump.

1. Clean all the gasket surfaces completely.
   
2. Apply a thin bead of sealer around the outside edge of the water pump along the gasket sealing area, then install the gasket onto the water pump.
   
3. Position the water pump on the engine, then tighten the water pump mounting bolts to 89 inch lbs. (10 Nm).
   
4. Install the water pump pulley and finger-tighten the pulley bolts.
   
5. Install the serpentine belt.
   
6. Tighten the water pump pulley bolts to 18 ft. lbs. (25 Nm).
   
7. Fill the cooling system.
   
8. Connect the negative battery cable, then start the engine. Let the engine run until it reaches normal operating temperature, then check for leaks and coolant level. Add coolant, if necessary, then turn the engine OFF.
   

2.4 enigine is the harder of the 3 enignes. it will need a timing chain to be removed and a coolant tube in the back of the engine to be removed. this job on the book calls for almost 7 hours.

if its 3.3 or 3100 its alot easier.

3100 is just 4 10mm pulley bolts and 5 or 6 small 8mm water pump bolts.

3.3 is alittle more work, but same concept as 3100 engine. more owkr only cause its in a tighter area.

good luck,
michael
