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.

    Tip

    Escort 1.9L Timing Belt Replacement


    Remove the serpentine belt, remove the lower crankshaft pulley, place a jack under the oil pan and jack up the engine slightly, remove the engine mount (right top). Remove the timing belt cover, loosen the timing belt tensioner and pull tensioner pulley back toward the rear of vehicle. I like to then tighten the tensioner bolt to hold it in this position, remove and replace belt. If you need to put the engine in time then look at the camshaft there is a small arrow in the center, it lines up with a dot on the end of the cylinder head. The lower timing mark is a small metal tip that sticks out from the lower gear, and it lines up with a notch cut into the front cover just behind the lower gear. Once aligned properly put the belt on the lower gear and without turning the lower gear or camshaft gear pull the belt tight up to the cam shaft the cogs in the belt will line up with the grooves, then place the belt around the water pump drive gear and under the tensioner, then push the belt over all gears by hand without turning the engine. Loosen the tensioner bolt and apply a little pressure toward the front of the vehicle and tighten the bolt. Replace everything else previously removed. Engine should start and run normally.

    I need to replace the belt tensioner on a 2000 Chysler Caravan with a 3.0L engine, with a/c. I would appreciation a diagram for properly installing the serpentine belt, and some instructions on how to...


    Hi, I have pasted the procedure for belt replacement below. To replace the tensioner as well, first take the belt off. Then remove the pulley from the tensioner. This will expose the single bolt that holds the tensioner on. Replace the tensioner and then the pulley (if replacing all). Then reinstall the belt.

    Alternator/Power Steering Pump Belt
    The alternator/power steering pump belt is provided with a dynamic tensioner to maintain proper belt tension.
    1. Disconnect the negative battery cable.
    2. Raise the front of the vehicle and safely support it with jackstands.
    3. Remove the right front splash shield.
    4. Release tension by rotating the tensioner clockwise (use a box-end wrench on the tensioner bolt shown in the picture.
    5. Remove the belt and install a replacement.
    6. Proper belt tension is maintain by the dynamic tension.
    7. Install the right front splash shield. Lower the front of the vehicle.
    8. Connect the negative battery cable.

    Looking for a diagram for a serpentine belt for a 2006, Dodge 2500


    The main drive belt or serpentine belt is important on any vehicle, but some have more than one belt to drive components from the crankshaft. The Dodge Ram and similar truck models have one true serpentine belt, a multi-ribbed belt that fits into grooves on various pulleys, that Dodge suggests inspecting for wear every 15,000 miles or 12 months.

    Disconnect the negative battery terminal. Because the electric fan can start even without the vehicle running, some mechanics suggest disconnecting the battery terminal while working in the serpentine belt area.
    2Locate the serpentine belt tensioner pulley. The belt tensioner pulley will have a bolt on its side. On some Dodge Ram models, the tensioner is directly below the air conditioner compressor pulley; look for it above the crankshaft pulley.
    3Rotate the tensioner pulley by turning the bolt, either with a wrench for some models or a breaker bar or ratchet for other models.
    4Slip off the belt and let the tensioner return to its position.

    4. Unplug the alternator wiring connector, then remove the battery terminal nut and wire.
    5. Carefully release the serpentine belt tension and remove the belt from the alternator pulley. Do not allow the tensioner to snap back into position once the belt is off the pulley.
    6. Loosen the alternator retaining bolts, then support the alternator and remove the fasteners. Remove the alternator from the vehicle.

    To install:
    1. Position the alternator in the vehicle and loosely install the retaining bolts.
    2. On 1994-98 models, tighten the top alternator bolt to 22 ft. lbs. (30 Nm) and the bottom bolt to 32 ft. lbs. (43 Nm).
    3. On 1999-99 models, tighten the rear bolt to 37 ft. lbs. (50 Nm) and the front bolt to 18 ft. lbs. (25 Nm).
    4. On 1994-98 models, install the alternator brace, then tighten the retaining nut(s) and bolts to 22 ft. lbs. (30 Nm).

    Remove and replace tensioner


    Without knowing which engine year you have ......the most common tensioner is held on with a bolt from the back of the unit.
    The bolt is accessed from the bottom of the vehicle.The bolt is at the rear of the engine on the passenger side above the power steering pump.The bolt screws into the tensioner assembly.
    It's not as bad as it looks.20min job.
