Look for any metal or plastic cover/protector for casing of parts/ moving parts or the radiator fan casing rattles are majorly caused by poor bolting of parts or cracked parts. . best to do this with a stick and to dip in the parts with caution and see if rattle disappears. hope this helps..

Remove and replace alternator


Hello,

Just follow these steps to remove and replace the alternator. You will need this tools, Serpentine belt tool, Battery wrench, Lug wrench, Floor jack, Jack stand, Socket set,

  1. Open the hood, locate the serpentine belt tensioner and move the tensioner off the
    serpentine belt with the serpentine belt tool. Slip the belt off the tensioner
    pulley with your other hand and then slowly move the tensioner back to its normal
    position. You can pinpoint the location of the belt tensioner by following the belt
    routing diagram, printed on the fan shroud.
  2. Disconnect the negative battery cable from the battery with the battery wrench.
    Push the cable end away from the battery so it doesn't make contact during the
    repair.
  3. Turn the lug nuts on the right-front wheel counterclockwise until they're loose
    enough for hand removal, but leave them on for now.
  4. Lift the right-front end with the floor jack and support it on a jack stand placed
    underneath the right-front frame. Remove the lug nuts and right-front wheel by hand
    and set them aside.
  5. Slip the serpentine belt off the alternator pulley by hand. You can access the
    alternator through the wheel well. Unplug the wiring harness from the alternator
    by hand and remove the ground strap with your socket set.
  6. Remove the alternator mounting bolts with your socket set. Lift the alternator out
    of the engine well, through the wheel well. Insert the new alternator in reverse of
    how you removed the old one.
  7. Thread the alternator mounting bolt through the new alternator and into the
    alternator bracket by hand. Tighten the bolts with your socket set.
  8. Attach the alternator ground strap with your socket set. Plug the alternator
    wiring harness in by hand.
  9. Slip the serpentine belt over the new alternator pulley. Reinstall the wheel and
    lug nuts by hand. Lower the Taurus of the jack stand with the floor jack.
  10. Move the belt tensioner aside again and place the belt on the tensioner pulley with
    your free hand. Hold the belt on the pulley and slowly move the tensioner back to
    its normal position. Reconnect the negative battery cable to the battery.
Hope this helps you.
Take care and good luck

I at about 89K on my '04 Jetta TDI and had the same issue. I was due for my 90K service to I took it to the VW dealer. They replaced the power steering pump and belt tensioner. This is the second tensioner that I have replaced this year. Thought the first one went out just because. Now it seems that the power steering pump was the cause. With both fixed, I have no scream and rattle from the engine. You might want to have both checked/replaced on yours. I'll let you know if the noise comes back. Good luck.

Hi, i have a toyota fielder 1.8cc with a some problem which has now come up. when i switch on esp in the morning after staying overnight, it produces some really annoying sound from the engine. when the...


If it is a 'squealing' noise it's probably the alternator/power steering drive belt. Before you turn on the engine in the morning, lightlt smear or spray some oil on the inside of the drive belt to lubricate it. If the squealing stops/disappears, then that's the fault ..

That squealing noise can be caused by an incorrectly tensioned belt, or a worn belt. Replacement is the only option.

The other frightening sounds can best be described as 'rattles' or 'tapping'. When a car stands overnight all the oil drains back into the sump (oil/pan).

There are two things (usually) that can be cause the rattle/tap:
1. Because the oil hasn't been pumped around the system, at start up worn big end bearings can rattle and tap on the crankshaft until the oil 'fills the gaps'. The tapping/rattling goes away as the engine warms and oil is pumped around the lubricating system.

A 'bottom end tapping' is a symptom of worn big ends (they are bearings at the bottom of the piston and fit around the crankshaft).

2. A rattle/tapping from the top of the engine can either be a worn camshaft or 'lazy tappets'. Again, when the engine warms and oil gets to the camshaft and tappets (also called 'hydraulic lifters) the noise will disappear.

If your car has this rattling/tapping noise - identify whether it is coming from just under the rocker box (ie the camshaft/tappets..) or the bottom end of the engine (big end bearings).

If the noise is coming from the top of the engine, try an oil change with a can of thick 'additive' included. A lazy tappet (lifter) isn't too much to worry about. A worn camshaft will affect the performance of the engine, though continue to do its job. An oil change with an additive included may help in quitening things down.

A bottom end tap/rattle (or 'knock') - the sooner that is sorted out the better.

How to fit a new fan belt to a mercedes 300d


Locate the tensioner pulley; as you face the engine it is located two in from the right and midway down. It can be identified as a the smooth wheel with the inside ribs of the V (fan) belt facing outwards. In the middle there is splined (torx) nut and a black collar at its base against the wheel. An 8mm socket should fit on this splined shaft pretty well if you don't have the correct size of torx socket. Set the socket wrench at the 3 O'clock position and lift it, as if to undo the torx shaft. With a bit of effort the tension pulley can be lifted against its spring and in the process the belt will become slackened. Make a note of the pulleys and the direction of the belt traced around them. Lift the tensioner pulley and slip the belt forwards. Release the pulley and remove the old belt. Fit the new belt all the way around the pulleys, using your previous sketched layout of the belt th paas a guide, but leave the tensioner pulley until last. Re-engage your socket wrench on the splined shaft and as before lift the pulley against its tension spring. Slip the back of the belt over the tensioner pulley and release the pulley to put the belt back under tension. Note the order of pulleys on which you fit the belt is not critical. On some engine models the belt is first fitted to the tensioner and then fed around until a small pulley, such as for the alternator on the right hand side, is the only one not fitted. By creating a bit of slack by lifting the tensioner pulley it is possible to slip the v belt over this last pulley. Just as note sometimes the clatter from the diesel unit is not just the engine. The tensioner pulley has a damper unit fitted to it to stop it jumping around when the engine is running. The bushes for this damper can wear and the metal mounting collars can rattle loudly result. This can be checked whilst the engine is running by locating the damper and pressing a long handled screw-driver to the end of the damper. If applying pressure to the damper creates a change in engine noise then it is likely that the bushes are worn. If that is the case it can be replaced, I have tried fixing the bushes but nothing has worked for me. I mention all this as this is a good time to address this when replacing the the v belt. The plastic collar at the base of the splined shaft on the tensioner pulley can be prised off and beneath it there is a 15mm tensioner pulley retaining nut; obviously the belt needs to be off first. Removing the tensioner pulley allows access to the 13mm damper mounting bolt.

Smooth wheel on the timing belt rattles butnut in middle is tight


The timing belt is not on the outside of engine. What you are describing might be the belt tensioner. The bolts you speak of in alternator are the mounting bolts. If the "smooth" wheel is vibrating, then replace the wheel. That is the belt tensioner.

Timing CHAIN tensioner you mean? Better have that noise checked ASAP. It may be a problem with the timing chain.
