My antifreeze keep leaking out , it started a few days ago.the car runs good i have had it two years without any problems can you tell me what might be going on , it the only car i have.


The water pump and related area may be leaking antifreeze. Check near the belt pulley for the water pump. There may be other issues that require the gasket further in the engine changed which is related to engine oil. My family had a 1998 Ford Taurus that had this problem and it cost a few hundred to have it fixed.

One may also look for a leak at the radiator (or hoses )which is further forward.

Fig. 4: Water pump mounting bolt locations 93163p88.jpg
Fig. 5: Front view of the water pump and thermostat housing 93163p99.jpg
WARNING
This procedure requires the removal of the timing belt. This is an extensive procedure requiring precision work, particularly at assembly. For more information, refer to Timing Belt Removal and Installation. Do not attempt to remove the belt without consulting the procedure; extreme engine damage may occur.

Fig. 7: A and B bolt locations 86823pi8.gif
Fig. 8: Exploded view of the water pump arrangement — 5VZ-FE engine 93163g19.gif
  1. Drain the cooling system.
  2. Remove the timing belt. For additional information, please refer to the following topic(s): Timing Belt Removal and Installation.
  3. Remove the idler pulley.
  4. Remove the thermostat.
  5. Disconnect the oil cooler hose from the pump.
  6. Remove the seven bolts and the tension spring bracket and then remove the water pump. To install:
  7. Clean all parts well. It is good practice to carefully clean all threaded openings, especially those exposed to coolant to remove rust and scale so at assembly, an accurate torque reading is obtained. This is important since gasketless applications like this depend on even clamp loads from the fasteners to avoid distortion and leaks. Remove any old sealer (Toyota calls it packing) from the pump and mounting area of the engine. Keep oil off the mating areas.
  8. Apply Formed In Place Gasket (FIPG) sealer to the pump-to-block mating surface and then tighten the bolts marked A in the illustration to 13 ft. lbs. (18 Nm). Tighten those marked B to 14 ft. lbs. (20 Nm). NOTE: The parts must be installed within 5 minutes of application of the sealant. Otherwise you must remove and reapply the sealer.
  9. Connect the oil cooler hose.
  10. Install the thermostat with a new gasket.
  11. Install the idler pulley.
  12. Install the timing belt.
  13. Install the drive belts and adjust the tension.
  14. Refill the cooling system and check for leaks.
2RZ-FE and 3RZ-FE Engines
  1. Disconnect the negative battery cable.
  2. Drain the cooling system.
  3. If equipped with an air conditioning compressor or power steering pump drive belts, it may be necessary to loosen the adjusting bolt, remove the drive belt(s) and move the component(s) out of the way.
  4. Remove the fluid coupling with the fan and water pump pulley.
  5. Remove the water pump. To install:
  6. Clean the gasket mounting surfaces.
  7. Install the replacement water pump using a new gasket.
  8. Install the water pump pulley and fluid coupling with the fan.
  9. Install the removed engine drive belts.
  10. Fill the cooling system.
  11. Connect the negative battery cable. Start the engine and check for leaks.

Step by step to replace water pump on a 1995 chevrolet camro.


Water Pump - REMOVAL & INSTALLATION
CAUTION When draining the coolant, keep in mind that cats and dogs are attracted by ethylene glycol antifreeze, and are quite likely to drink any that is left in an uncovered container or in puddles on the ground. This will prove fatal in sufficient quantity. Always drain the coolant into a sealable container. Coolant should be reused unless it is contaminated or several years old.

(see Figures 1 and 2)
  1. Disconnect the negative battery cable.
  2. Drain the cooling system into a suitable container.
  3. Remove the air intake duct.
  4. Remove the top coil of the ignition coil pack.
  5. Loosen the tensioner pulley bolt/screw.
  6. Disconnect the heater hose from the water pump.
  7. Loosen the water pump pulley bolts/screws.
  8. Unfasten the power steering bracket bolts/screws.
  9. Remove the serpentine drive belt.

200 2.0 jetta cooling system diagram. i have a leak on a metal hose that goes into block left side of engine. how do i fix?


The metal pipe you are talking about is a heater pipe. it carries coolant around the block. i would just buy a new pipe and replace the old one. if you use epoxy or something its probably going to leak. there is a bracket built into the pipe and its screwed to the heater hose flange on the side of the motor. once you remove the two nuts you should be able to take a prybar and pry it from the block. (Its just pushed into the block and sealed with an o-ring)
