This means you have a leak on your cooling system.Be very careful with that as if you are not careful it will end up blowing the head gasket which will be costly to fix.My suggestion is to find the leak, drain the cooling system and fix the leak which will be less costly and easier than having a replacement head gasket.

Diragram on how to change the water pump on a 1995 z24 cavalier 2.3


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.

Fig. 9: Water pump and cover mounting - 2.3L and 2.4L engines (click over image for zoom)

To install:

  1. Thoroughly clean and dry all mounting surfaces, bolts and bolt holes. Using a new gasket, install the water pump to the cover and tighten the bolts finger-tight.
  2. Lubricate the splines of the water pump with clean grease and install the assembly to the engine using new gaskets. Install the mounting bolts and nuts finger-tight.
  3. Lubricate the radiator outlet pipe O-ring with antifreeze and slid the pipe onto the water pump cover. Install the bolts finger-tight.
  4. With all gaps closed, tighten the bolts, in the following sequence, to the proper values:
    1. Pump assembly-to-chain housing nuts-19 ft. lbs. (26 Nm).
    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).
  5. Using new gaskets, install the exhaust manifold. Make sure to following the tightening sequence and torque specifications given in the exhaust manifold procedure located in this section.
  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.

Hope helps; remember to rating this answer and leave a testimonial comment. Thank you for using FixYa.

I am seeing water behind the pump on the top of the motor in the v under all the fuel injection / intake is that normal for water pump to leak there if its bad?


its not normal. the water pump will leak in front, not back. There is a pipe and hose down in the VEE that can leak. If the pipe is bad, you will need to remove the pump to replace it. The intake manifold will need to come off, to replace the pipe/ hose. the hose connects a pipe behind the water pump to a pipe at the rear of the block to a heater hose.

    Coolant is leaking from hose/pipe under coolant reservoir


    It sounds like the outlet pipe from rear of water pump,which takes the hose from the rear plastic pipe, which is very common problem in Daewoo Leganza/Nubira/Lanos Australian 2.0/2.2 DOHC engines.Either the hose itself, the plastic pipe, or the alloy outlet for the hose on rear of water pump, which is subject to corrosion.You will have to confirm where leak is from, if it is from hose to rear of water pump, you can try re-clamping hose or replacing hose, if it is corrosion of that outlet,the part is available @$40-60 new, but it is a fairly major job because timing cover timing belt and then water pump must be removed...it is a difficult workspace in front of and behind that engine,the manifold and alternator are both in the way , it may be possible to do it in car but you may even be better off removing engine to work on.Good news is that this is a great opportunity to replace T-belt and water pump and pulleys at the same time..Sorry its not that great a news, its not a very easy DIY job, but it is do-able if you have some experience and tools.

    8. Raise and support the front of the vehicle.
    9. Index the exhaust manifold-to-exhaust pipe flange bolts.
      1. Turn bolt bolts in evenly to avoid cocking the exhaust pipe and binding the bolts. Turn the bolts in until they are fully seated.

    10. Install and secure the radiator outlet pipe to the transaxle and oil pan.

    On manual transaxles, install the exhaust manifold brace.
    1. Install the timing chain tensioner and chain cover.
    2. Attach the lower heat shield.
    3. Lower the vehicle.
    4. Attach the exhaust manifold brace. Tighten the manifold-to-exhaust pipe nuts to specification.
    5. Attach and secure the upper heat shield.
    6. Connect the oxygen sensor wiring.
    7. Fill the radiator with coolant water mixture until it reaches the heater hose coolant outlet, then install the hose and continue to fill. This will assist with the complete cylinder block fill.
    8. Connect the negative battery cable.
    9. Start the engine and top off the cooling system and check for leaks.
