Good Evening, sounds like your crankshaft pulley has come apart. there is a rubber dampener that you are looking down at. If you buy a new crankshaft pulley you will be ok. Hope this helps.

Intermittent sqealing engine runs quietly for a while, then more squealing. no overheating. friends tell me could be problem with water pump


Most likely a bearing on one of the engine pulleys, and probably the idler pulley. The best way to find out is to remove the belt and spin each pulley by hand. Listen for "roughness" or a grating sound. Try to move the pulley in and out to check for play. Little or no play is good. All should spin smoothly and fairly easy.

NOTE: Make sure you know how the belt goes on before you take it off. Draw circles on a piece of paper to match your pulley size and locations, then draw the belt around the pulleys exactly as it appears on the engine. Hope this helps....Let me know!!!

Apparently the serpentine belt was thrown off my 1998 Mercury Mystique. It appears in good condition. Should it be replaced or can it be reused? Also, do you have a belt diagram? Thank-you.


You can reuse it. But you need to find out why it was thrown off. Check all the pullies by grabbing them and checking for side to side movement, With the exception of the power steering pump pulley (which has some in and out play) they all should have no play. Just turn in nice smooth circles. Sorry I don't have the diagram, but there should be one under the hood. Sometimes on the bottom of the hood.

How to replace the water pump


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.

2S-ELC Engines

  1. Drain the cooling system.
  2. Remove the timing belt as described in this section.
  3. Remove the alternator adjusting bar.
  4. Disconnect the lower radiator hose from the water inlet housing.





    Fig. 1: Exploded view of the water pump mounting
    89553g42.gif



  5. Disconnect the water temperature switch from the water inlet housing.
  6. Disconnect the water by-pass hose from the water pump.
  7. Remove the two heater pipe clamp bolt. Remove the two nuts and heater pipe
    with gasket. Replace the gasket.

    few times with a rubber mallet.
  10. Installation is the reverse of removal. Make sure all the water pump and
    engine contact surfaces are clean and install the new O-ring into the pump cover
    groove.
  11. Install the water pump with the three bolts. Tighten the bolts in sequence
    to 82 inch lbs. (9 Nm).
  12. Fill the cooling system to the proper level with a good brand of ethylene
    glycol based coolant. Start the engine and inspect for leaks.

3S-FE Engines

    89553g46.gif

    To install:

  8. Replace the two O-rings and gasket with new ones, coat the by-pass O-ring
    with soapy water and then connect the pump cover to the by-pass pipe. Do not
    install the nuts yet!

Could you give me the steps toinstall a new valve cover gasket, please.


Basically, remove anything that obstructs the cover and will prevent the easy removal and reinstallation.

In dealing with the main part, preparing and sealing the valve cover:

NOTE: some engines use jusr RTV as the gasket itself, others use a gasket and a coating of RTV. The amount of RTV is the difference and without a gasket, it is necessary to allow the thicker bead of RTV to set up longer before applying the two pieces together and installing the bolts.

On to the standard valve cover with a gasket.

If the cover is not a cast material, then make sure you turn the cover upside down and carefully flatten any overtightened spots where it is bolted to the head. You want the gasket area smooth and clean of any wax, oil, grease, or debris. You also want the mounting surface to be clean of oils and grease, etc., and smooth before installing the new gasket.

New gaskets leak due to improper surface prep more than any other reason!

Once the mating surfaces are clean, place the valve cover against the area it mounts to, without the gasket to make sure it isn't warped or bent causing other problems, if it's straight, apply RTV to the Valve Cover first, then installing the gasket into that part after letting the RTV sit for a minute or two you can apply the RTV to the bottom side where it will mate to the engine surface, just a thin coat should be fine, allow it to set a minute or two after making a smooth sealing surface and install. (I prefer Copper Plus for valve covers, it's orange Hi-Temp and seals well)

Do not overtighten the valve cover mounting bolts/nuts. They only get tightened to "snug", not to a torque setting as it will bend the valve cover, causing leaks. Tighten from the middle bottom, then top, then work from left to right outwards keeping the pressure even and only making things snug.

Once done, allow engine to sit a few hours for the RTV to set up after reassembling the items you had to remove to gain clearance.

If the surfaces were clean and smooth, the gasket had a light coat of
RTV on both sides-there is no reason for any leakage due to the gasket. After letting the RTV set, re-tighten, or snug the mounting bolts again, start the engine and warm up, shouldn't have any leaks. Once cool, re-check the same mounting bolts to make sure they are evenly snug.

(Things change after heat is applied and then they cool, this is just preventative maintanance)

A Vacuum gauge will identify any exhaust problems/restrictions that would cause gaskets to leak, should you encounter leakage soon after repairs.

Good luck.

Need diagram of serpentine belt


As this forum will not allow images and the link for my information requires a paid subscription I propose the following: email me at curtisephlush@yahoo.com and I can sen you a document with a belt routing illustration.

Short of that, I can give you a verbal description, but it is sort of confusing:
Top of CAM to top of ALTERNATOR - bottom of ALTERNATOR to top of nearby (front) PULLEY - bottom of PULLEY to top of A/C COMPRESSOR - bottom of COMPRESSOR to bottom of CRANK - top of CRANK to bottom of middle PULLEY - top of middle PULLEY to bottom of rear TENSIONER - top of TENSIONER to back to top of CAM. Remember the serpentine belt has ribs on only one side, the ribs face AWAY from the two guide pulleys and TOWARD the pulleys on the Alternator, Compressor, Crank, Cam and Tensioner. You should tell by the pulley being smooth or ribbed as needed.
