Why is there a squeal in the front end of my V6 Essex, but only when the engine is hot?

Not the alternator or water pump as have disconnected the fan belt. Sounds mechanical

Why no heat in 2001 mazda protege


Possible that the fan belt is not tensioned right or that the water pump is binding causing low flow through the heater.
If belt is not loose, release it more and try turning the water pump by hand to see if it is binding.

Water Pump leaks from the front end of the Wagon.


follow this steps and fix it. God bless you
  1. Determine the Reason for Water Pump Failure
    • 1 Repair a water pump by checking your car for a failure in the bearings. You can test for bearing failure by seeing if there is any play in the shaft that is connected to the electrical fan blades, as well as the drive pulley to the pump itself.
    • 2 If you notice any free play in the shaft or the pulley, you will need to take the pump apart and replace the bearings.


    • 3 Determine if the water pump failure is due to a leak in the casing. Examine the water pump housing for leaking or water stains in the drainage hole next to the pulley.
    • 4 If water is dripping from this hole, then the seals inside the pump need to replaced in order to repair the pump.
    Remove the Water Pump for Repair
    • 5 Allow the engine to cool completely before removing any part of the cooling system. Never open a radiator cap or plug while the engine is still warm.
    • 6 Disconnect the car battery. This will prevent the electrical fan from turning on while you are under the hood.
    • 7 Drain the radiator of all fluid and disconnect the radiator hoses. Collect the fluid with a plastic container and keep it in a safe place until you are ready to put it back into the radiator.
    • 8 Remove the fan assembly. This will include the shroud, the fan and the fan belt. Disconnect the electrical leads for the fan.
    • 9 Remove the pulley for the fan belt as well in order to have access to the water pump.
    • 10 Use a socket set to remove the water pump from its engine mount.
    • 11 Open the housing for the water pump and replace the seals or bearing as necessary. Some auto parts stores carry repair kits that have both the seals and bearings for specific types of water pumps.
    • 12 Reassemble the cooling system by replacing the water pump, pulley, fan belt, fan assembly and radiator hoses. Refill the radiator with the fluid.
    • 13 Start the engine to see if the water pump repair was successful. Check for leaks before you take the car out on the road.

  1. Drain the cooling system.
CAUTION When draining the coolant, keep in mind that cats and dogs are attracted by the 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.
  1. Disconnect the lower radiator hose from the water pump.
  2. Remove the drive belt, fan, fan spacer, fan shroud, if so equipped, and water pump pulley.
  3. Remove the alternator pivot arm from the pump.
  4. Disconnect the heater hose at the water pump.
  5. Remove the water pump.
  6. Before installing the old water pump, clean the gasket mounting surfaces on the pump and on the cylinder block. If a new water pump is being installed, remove the heater hose fitting from the old pump and install it on the new one. Coat the new gaskets with sealer on both sides and install the water pump in the reverse order of removal. Torque the mounting bolts to 14-18 ft. lbs.

  4. Loosen the alternator pivot bolt and the bolt attaching the alternator adjusting arm to the water pump. Remove the power steering pump bracket from the water pump and position it out of the way.
  5. If necessary, remove the air conditioner compressor and bracket. The refrigerant lines should remain connected.
  6. Remove the bolts securing the water pump to the timing chain cover and remove the water pump.
  7. Thoroughly clean the mounting surfaces of all gasket material.
  8. Install the water pump in the reverse order of removal, using a new gasket. Torque the bolts to 15-22 ft. lbs. in the sequence shown.

Noise you are hearing may be the front bearing in the alternator. When you first start the car the alternator is working harder to replace power you used to run the starter. You can verify the noise source by putting a long bar against the alternator and holding the other end on your ear. be careful not to get the bar into the belt or it can do damage.

Camry overheating


Possible stuck thermostat(located front LH side below the alternator), or faulty water pump(inside timing cover)!! The fan has no connectors because its hydraulic driver through the power steering pump(V-6 models only). You may disconnect the switch on the powersteering pump to test the fan.....with the switch unplugged rev the motor to 2200RPM and you should hear the fan increase in speed. If not check the filter (LH side of the radiator) its black with rubber tubing on each side. Check also power steering fluid. Hopefully this helps!!
