Could be get the specs and reset the timing. If it contiues then try working on the fuel filter or idle speed.

SOURCE: timing engine

I had a 2.4 L engine in a caravan and replace the water pump that was controlled by the timing belt.
I was having the same problem, I called my bother in law to help. The crank shaft has to stay perfectly timing on the low end. The cam shaft marks are set exactly one half of a tooth apart. So when looking at it, The left side cam gear mark is a half a tooth higher then the right side. Then you have to try and slip on the belt . That is the easy part. When letting go of the timing belt tensioner the marks should line up perfectly across from each other. You have to take off the belt again and make sure you keep correct tension on the crank shaft so the mark is not moving when you are putting on the belt. There is a web site call Alldata.com. The web site cost a few dollars but it willl give you a detail instructions on how to time the engine with pictures to guide you. This is the same web site the pro's use.

I hope this has been helpful.

Oh, by the way you are lucky because the engine is not an interferrence type , so you can not damage the valves at least. Since you know the oil pump is out of time , check all the spark plugs again , they are probably oil soaked .

My 1990 toyota 4runner 3.0l v6 timing belt has a tension spring, not the piston tensioner. How do i adjust the timing belt tension ?


The spring tensioner should keep the proper tension on the belt. If the tensioner is not keeping the belt taught, I would suggest having both changed. Much cheaper to have done before the belt skips.

Replaced belt still makes noise


Dear John,

Try this. Is could be because the old belt was slipping and has polished the pulleys or "glazed" them. So before you replace that noisy belt scrub all of the pulleys well with a scotch brite pad, or a good wire brush to remove the glaze and rough up the surface. Clean them off with brake cleaner afterward. Belts work by friction so if the surface is polished too much the belt will slip, Or try adjusting the belt TENSION will correct the problem. If this does not correct the problem you can try removing the belt altogether, and "reversing" it, and then reinstalling and properly adjusting the tension.
Hope This helps.

I am trying to hange the serpentine belt on my 09 lancer rallyart and it keeps slipping off


Locate the two belts on the left side (passenger side) of your Mitsubishi Lancer. The outer belt is a serpentine belt, operating four pulleys and the inner belt is your alternator belt.

  • 2 Follow the serpentine (outer) belt to the three pulleys lined up vertically near the front of the engine compartment. Locate the middle pulley, which is the tension pulley for the belt.
  • 3 Loosen the bolt on the middle pulley with a socket wrench by turning counter-clockwise. Do not remove the bolt, just turn it a couple of times. Loosen the tensioner bolt on the side of the of the pulley, facing the front of the vehicle.
  • 4 Remove the serpentine belt and then loosen the bolt on the alternator. With the alternator loose, move it forward so that the alternator belt loosens up and then remove belt from the pulleys.
  • 5 Install the new alternator belt by placing it over both inside pulleys. Tighten the tension on the alternator belt by moving the alternator back and keeping tension on it by holding it back with a long screwdriver. While the alternator belt is tight, use a socket wrench to tighten up the bolt on the alternator.
  • 6 Place the serpentine belt back on the pulleys and then use a socket wrench on the bolt on the front of the tension pulley. Once the serpentine belt is tight, tighten up the bolt in the middle of the tension pulley.
  • 7 Start the Mitsubishi Lancer's engine to test the alternator belt and make sure it is working properly. Once you have verified it is working, turn the engine off.

    Water pump where is it the belt is loose


    the water pump is under the timing chain cover. if your serpentine belt is loose, that is the belt you can see, then your tensioner is shot. you can buy a new tensioner for about 50 bucks at a parts store. search on www.youtube.com for video directions on how to replace it. if your serpentine belt has not been changed this is a good time to do that as well as it has to come off. replacement of the tensioner and belt is done via a service panel behind the right front wheel.

    Where is the adjuster for the fan belt on an escort gti


    There is no manual way to adjust the tensioner for this car. If the belt is loose check to make sure it has not stretched over time and needs replacement. Also look at the tensioner itself, if you can move it by hand it needs to be replaced because it is no longer keeping tension on the belt. On that car, the alternator acts as the tensioner.

    There is a squeeling by the belt/pulley area


    It's a loose belt for sure.

    If you have a spring loaded tensioner, and the belt has stretched with time, the tensioner will reach the limits of its travel without tensioning the belt enough to prevent that squeal.

    If it has an adjustable tensioner, tighten the belt up.

    My 91 corolla screams when warm and accelaerating


    If by "scream" you mean very annoying, high-pitched squeal coming from under the hood... it could be one or two things

    It's likely that it's either a loose or bad drive belt. Check the tension on all of your belts by pushing down or pulling up on each belt. There should be some deflection...but very little. If you find a loose belt, simply adjust the tension, which is typically done by adjusting the alternator, and occasionally, another swivel mounted type component such as a compressor, or power steering pump. It's very important to make sure not to overtighten. If you push or pull on the belt and it barely moves, it's way too tight and needs to be loosened up.

    In some instances, there is a spring-loaded idler tensioner, and it cannot be adjusted. If your belt isn't fitting properly with this type of tensioner, chances are it isn't routed properly, or you installed the wrong belt. There usually a diagram under the hood that shows how the belt should be properly routed. If belt is properly routed and still loose, chances are you have to replace the tension idler.

    If all of your drive belts are in good shape, this last possibility isn't as common, but still can be quite noisy once it's going bad... the waterpump. You typically find this with older cars, because of corosion buildup over time, and bearings wearing out. In this case, you have to replace the water pump, along with gasket and sealant.

    Hope this helps

    My belt is squaling and it is loose how do i titeing it


    This engine uses an automatic tensioner system to keep the belt tight. The tensioner is generally getting weak, causing this problem. It is not an easy one to replace, and also have the belt replaced. We use the Goodyear Gator belt, and resolve this noisy problem for years and years.

    My engine got so noisy and when i removed the engine cover the timing chain looked a bit loose


    The timing belt shouldn't cause the engine to be noisy unless it is so loose as to slap parts surrounding it. The engine will become noisy if a loose timing belt skips a tooth or 2 and messes up the timing of the engine.

    On another hand, if it is visually loose at the timing gears it is imperative to get the system looked at by a mechanic. The belt may be ok but the tensioner may need to be replaced but if you replace the tensioner, you may as well replace the belt. Timing belt should have some play at the point between the crank pulley and the cam gears.

    Take it to a certified mechanic to have it looked at and measure the play on the timing belt to check if it is still in specifications.

    Timing belts are only good for about 60,000 miles. If you are over that I would recommend replacing the belt and tensioner but may vary from car to car. Check a repair manual for specifics to your vehicle.

    How can one tell if a tensioner is bad on a 1998 dodge ram 1500? Also is there a such thing as tightening a belt with these tensioners


    The tensioner is a spring loaded unit that is supposed to provide the proper tension on the belt with out adjustments. Ususally if a tensioner goes bad it is not providing presure on the serpentine belt (loose belt, squeel, or squeek) or it has a bad bearing in the tensioner pulley (noisy, siezed). The tensioners are sold as an assembly in either case. If the tensioner went bad it is a good idea to replace the serpentine belt at the same time.
