Question about 1993 Mercury Topaz

1993 mercury topaz GS Engine noise

My engine making loud sounds. 2.3 engine. I changed the bearings in one of the pulleys, I checked the crank damper/pulley, there was no play in it.
After I changed the bearings in one of the pulleys, I left off the belt, no noise, when I put the belt back on it many noise.
Any thoughts

Another guess would be the water pump going bad. That noise can be loud when it gets pretty bad and makes like a metal on metal grinding noise

Belt wont stop squealing


Make sure all the pulleys are lined up and the automatic belt tensioner is not off to the side due to a bad pulley bearings. Also check the crank pulley for walking outward and throwing the belt alignment off. If the crank shaft pulley appears to have moved out you will need to replace the crankshaft harmonic damper

Replaced serpentine belt on 1995 dodge ram 1500 and squeal's and chirp's like mad .help me please!!


Make sure that a) none of the pulleys are loose due to failing bearings b) that the belt tensioner is applying enough tension to the belt c) belt tensioner damper is working. First twist the belt by hand between the longest point between pulleys by about 90 degrees. This should be difficult to do if the tensioner is applying correct tension. Next while the engine is idling look at the belt alignment from the side to be sure the belt is not wandering backwards and forwards on the pulleys. Also see if the tensioner pulley is bouncing about. Perhaps best to again remove belt and wiggle each pulley by hand to detect any play in the bearings. If tensioner is bouncing it is likely the damper spring is not working as it should.

The bottom pulley for the drive belt is wobbling and making a loud sound. do i need to replace the pulley and is it the bearings in the pulley?


The bottom pulley on any engine is attached directly to the torsional vibration damper which is attached to the crankshaft. That pulley drives the serpentine belt and has no bearings. First thing you need to do is find out if the pulley bolts have become loose or if the damper on the crank is loose.
If you find the pulley loose, if the bolt holes are not elongated, just tighten it back up. If the damper is loose, remove it from the engine (puller usually necessary) and inspect the crank snout and the alignment key for wear. Any damage to the damper requires that it be replaced. If the crank snout is severely damaged, that requires that the crank itself be replaced (very expensive).

I have a 2000 nissan sentra my harmonic balance is bad according to a autozone person it moves when the car is on and he told me it needs to be replaced because it has play i need to replace and find out...


The harmonic balancer is integrated with the crankshaft pulley, and if replaced requires taking the bolt out from the side of the 4 cyl. engine.

I would recommend that an experience engine rebuilder perform the service.

Inspect the Harmonic Balancer:

The harmonic balancer (vibration damper) is inspected for signs of wear in its center bore.
  • Also inspect the rubber mounting for indications of twisting and deterioration.
  • The outer ring can slip, causing an out of balance condition. Replace any harmonic balancer that has slipped.
  • With the cylinder head removed and the piston at top dead center (TDC), make a visual comparison. Do the timing marks for TDC on the timing cover and damper appear to be accurate.
  • Be sure the damper is the correct one for the vehicle. The wrong one can be worse than none at all.
  • Sometimes a damper can become loose on the crank. Check the keyway for wear that can result from improper damper installation, the wrong size key, or a loose damper hub to crank fit.
  • Be sure all pulleys are straight. A damaged pulley can force a crankshaft to bend during engine operation.
This is a general guide on replacing the harmonic balancer, but there are other instructions that the rebuilder would follow to actually do the service for you:

To remove the harmonic balancer, the cylinder head and timing cover must be removed and the piston should be at top dead center (TDC).
  • Install the vibration damper by pounding it on, or use a special installation tool.
  • Generally, the damper is installed unit it bottoms out against the oil slinger and the timing sprocket.
  • If in doubt, install the water pump and pulley, and then pound the damper into place until its pulley aligns with the water pump pulley.
  • It is advisable to use the installation tool, because pounding on the damper can cause stress on the crank thrust bearing surface.
  • It is best to stand the engine block on end and support the crankshaft if the damper must be pounded on.
  • Some vibration dampers are not pressed-fit on the crankshaft.
  • Be sure to install a large washer behind the damper retaining bolt on these engines; otherwise, the damper might fly off, causing damage and a safety hazard.

My 2006 2.0 litre turbo volkswagon passat started making this very loud whistling noise yesterday evening when i left owrk. The car had warmed up and I start hearing this noise. What could this be? No...


You are the bestt person to identtify the source of the sound before we can go about a long check list. so open up the bonnet if you think it is from the engine side. Look for possible noise from
1. water pump
2. Alternator bearings
3. Idler pulley
4.AC clutch pulley
5. Belts..Tip Is: try to pour some water over the belt to confirm
6. main crank pulley
Hope you check this out. Helpful I hope. Good day

I have a 2000 Lincoln Continental 4.6L V8 with 105,000 miles. When starting the engine there is a loud squealing noise coming from the center pulley on the engine. (crank shaft Pulley?) How hard is this to...


It may be a idler pulley bearing starting to freeze up remove the belt and turn all pulleys,power steering pump, alternator, idler pulley , etc. to find out if there is excessive resistance offered if so this is the culprit, on the idler pulley check the raidial play in the bearing by trying to move it by holding it with your hand and try to wiggle it gently back and forth same with the other (pulleys) check for loosness or play in pulleys bearings if everything checks out ok the battery may be running low and upon startup the alternator is under alot of strain to compensate for the recent drain on the battery while it is stressed to turn the starter to start car, your car may be drawing power from the battery as the car sits causing this condition disconect the pos. terminal of the battery and run a positive voltmeter wire to battery terminal then run negative volt meter wire to the now removed positive battery terminal cable set the voltmeter to dc there should not be 12 volts present if so there is and open circuit present drawing down the battery as the car sits while off.

Good luck

Loud squealing sound in my engine


Try removing the belt and turning each pulley by hand. If everything is smooth and free, with the belt still off, drive down the block once and see if the noise is there (this will eliminate all rotating accessories on the front). If you hear the noise, then there is a problem deeper inside. Oil pressure is good? Dont' forget when doing this, you will have no power steering, so be careful.
