How to tension a serpentine belt

I have installed a new water pump and need to tighten the belt on a 1990 Dodge Caravan with a 3.3 litre engine.

    the belt will not go around the water pump because it is too tight. I need to loosen it, put it around the water pump pulley and then tighten it

  • Samuel Charles Spriggs May 11, 2010

    This car may have an automatice tensioner. Do you see an idler in the belt path? It'll be a wheel on a bracket with a square hole in the bracket.



    I assume you have the belt on -- is this correct?

It sounds like you have an auto tensioner. There is a square hole in the bracket the tensioner is mounted on. Put a breaker-bar drive or ratchet-drive (3/8 or 1/2) in that hole -- this will allow you to move the tensioner so you can get the belt around the water pump.

How do i take of a pulley and tensioner of a 94 Dodge Caravan 3.0 L V6


You'll need a Serpentine Belt Tool and a socket set.

Rotate the Caravan's serpentine belt tensioner assembly clockwise to relieve the tension on the belt. Slip the belt off the tensioner with your free hand before rotating the tensioner back to its home position. Remove the tool.
Extract the two mounting bolts that hold the serpentine belt tensioner assembly to the Caravan's front engine cover using your socket set. Depending on your physical size and dexterity, you may find this easier to accomplish through the top of the engine well or through the passenger-side wheel well.
Pull the old serpentine belt tensioner assembly out of the Caravan's engine bay by hand. Place the new serpentine belt tensioner assembly on the Caravan's front engine cover and bolt it in using your socket set.
Rotate the new serpentine belt tensioner assembly clockwise with the serpentine belt tool and then place the belt on the pulley by hand. Rotate the new serpentine belt tensioner assembly back into place. Remove the tool and close the hood.

Replace alternator


The alternator belt on the 1999 Dodge Caravan also controls the air conditioner compressor, the water pump and the power steering pump. The belt is called a serpentine belt, and it is designed to fit around all of the accessory pulleys at the same time. As the belt travels around each accessory pulley, it enables the accessory to operate. Once the belt is damaged, cracked or frayed, you should change it before it breaks. If that happens, each of the accessories will stop working.

Open the hood and prop it up so that it does not fall. Engage the parking brake.

Inspect the top surface of the fan shroud for the serpentine belt routing diagram. Follow the routing instructions on the diagram to install the new belt.

Locate the serpentine belt self-adjusting tensioner on the front of the engine. The tensioner is directly below the alternator. Use the bolt that connects the tensioner pulley to the tensioner arm to rotate the tensioner.

Turn the tensioner device counterclockwise to move the tensioner. This will relieve the tension from the belt. Once the belt has enough slack in it, slide the belt out from under the tensioner pulley.

Lift the belt off each accessory pulley. Slide the belt around the fan blades and out of the engine area.

Lay the old belt next to the new belt to ensure that the new belt is the correct width and length. Slide the belt around the fan blades and around the crankshaft pulley on the bottom of the engine.

Follow the belt routing diagram to position the belt around the air conditioner compressor pulley, the power steering pump pulley, the water pump pulley and the idler pulley. Once the belt is routed inside each accessory pulley, inspect the belt to make sure that it is securely inside the pulleys.

Crank the 1999 Dodge Caravan for 10 to 15 seconds to completely seat the belt ribs in the grooves on each accessory pulley. Shut the engine off and close the hood.

If the belt routing diagram for the 1999 Dodge Caravan is missing, use a pen and a notepad to draw the exact routing of the old belt and use it when installing the new belt.

Serpentine belt slipped off. 1998 Dodge Gran Caravan 3.0 litre 6 cylinder


On this particular model of the 1998 Dodge Grand Caravan I determined that the upper hose from the water pump had slipped off and anti-freeze squirted on the serpentine belt causing it to slip off. Once the belt gets slick it never stays on. I replaced the belt by loosing the tensioner which is the idler pulley located in the center of the configuration, A big thanks to user motor1258for the configuration diagram.

Need to replace oil pump assembly


Remove the Oil Pump
1.
Step 1

Drive your Dodge Caravan up onto ramps or lifts so you have room to work as you pull out the oil pump. You could also use a jack, but make sure you brace the front wheels and engage the parking break so the car doesn't roll.
2.
Step 2

Disconnect the negative battery cable on your Dodge Caravan. Drain the engine oil and coolant into separate pans. Take the vehicle off the ramps or lifts. Remove the accessory drive belts and use an engine support tool to hold the weight of the engine.
3.
Step 3

Take out the right engine mount and bracket. Take off the timing belt cover and loosen the bolts on the timing belt tensioner. Remove both the tensioner and the timing belt then raise the vehicle back on the ramps or lifts.
4.
Step 4

Take out the oil pan assembly and remove the oil pump pick-up and the O-ring. Take the crankshaft damper out with a good puller. Use a puller to also draw the crankshaft sprocket from the front of the crankshaft.
5.
Step 5

Loosen the bolts on the oil pump and take them off. Remember where they were since you'll need to replace them later. Unscrew the relief valve.
Install the New Oil Pump
6.
Step 1

Clean all the parts to remove contaminants and debris then install the inner rotor. Make sure the chamfer faces the cast iron oil pump cover on the back. Torque the bolts to 105 in. lb.
7.
Step 2

Install the relief valve, followed by the spring, gasket and cover cap. The cover cap should be tightened to 40 ft. lb.
8.
Step 3

Fill the rotor cavity with clean engine oil to prime it then insert a new O-ring seal into the oil pump. Put Mopar Gasket Maker or equivalent anaerobic type gasket sealer on the flange of the oil pump body.
9.
Step 4

Align the oil pump rotor flats with the flats on the crankshaft and install the pump slowly, tightening the fasteners to 20 ft. lb. Add the new front oil seal and install it with the spring side facing the inside of the engine. Even it out with the engine cover.
10.
Step 5

Install the crankshaft sprocket with the special sprocket tool. Put on the oil pump pick-up tube and O-ring and torque the bolt to 20 ft. lb.
11.
Step 6

Insert the oil pan and install a new oil filter. Lower your vehicle then install the timing belt and covers and crankshaft damper with a tool specialized for the 2 mm by 1.75 by 150 mm bolt. Tighten the center bolt to 105 ft. lb.
12.
Step 7

Put on the accessory drive belts and adjust them to the right tension. Put on the engine mount and bracket then take out the engine support tool.
13.
Step 8

Add fresh oil to the engine and refill the cooling system. Use a 50/50 mixture of clean, ethylene glycol antifreeze and water in the cooling system. Start your engine and check for leaks.

The bad news is on your vechile you have to remove the timing belt, but here's a step by step.
  1. Disconnect the negative battery cable.
  2. Remove the drive belts.
  3. Drain the cooling system.
CAUTION When draining coolant, keep in mind that cats and dogs are attracted by ethylene glycol antifreeze, and are quite likely to drink any that is left in an uncovered container or in puddles on the ground. This will prove fatal in sufficient quantity. Always drain the coolant into a sealable container. Coolant should be reused unless it is contaminated or several years old.
  1. Remove the timing case cover and timing belt. Refer to Timing Belt Covers and Timing Belt Removal procedures.
  2. Remove the pump assembly mounting bolts.
  3. Separate the pump assembly from water pipe and remove.
  4. Clean gasket and O-ring mounting surfaces.
  5. Install a new O-ring on water pipe and lubricate with water.
  6. Install a new gasket on pump body.
  7. Press the water pump assembly into water pipe.
  8. Install pump mounting bolts and tighten to 27 Nm (20 ft. lbs.).
  9. Install timing belt and cover. Refer to Timing Belt procedures.
  10. Install drive belts.
  11. Fill the cooling system
To remove timing:
0900c152800661ff.jpg
The timing belt can be inspected by removing the upper (front outer) timing cover.
  1. Disconnect the negative battery cable.
  2. Remove the accessory drive belts.
  3. Remove the timing belt covers.
  4. Identify the timing belt running direction to avoid reversal during installation.
  5. Loosen timing belt tensioner bolt and remove timing belt.
  6. Remove the crankshaft sprocket flange.
To install:
  1. Rotate the crankshaft sprocket until timing mark on crankshaft sprocket is lined up with the oil pump timing mark at 1 o'clock position.
  2. Rotate the (inner) camshaft sprocket until mark on (inner) camshaft sprocket is lined up with the timing mark on alternator bracket.
  3. Rotate the (outer) camshaft sprocket (radiator side) until mark on the sprocket is lined up with the timing mark on the timing belt inner cover. Refer to timing belt illustration.
  4. Install the timing belt on the crankshaft sprocket while maintaining pressure on the tensioner side.
  5. Position the timing belt over the camshaft sprocket (radiator side). Next, position the belt under the water pump pulley, then over the (inner) sprocket and finally over the tensioner.
  6. Apply rotating force in the opposite direction to the camshaft sprocket (radiator side) to create tension on the timing belt tension side.
  7. Rotate the crankshaft in a clockwise direction and recheck engine timing marks.
  8. Install the crankshaft sprocket flange.
  9. Loosen the tensioner bolt and allow tensioner spring to tension the belt.
  10. Again rotate the crankshaft in a clockwise direction (2) full turns. Recheck the engine timing. Tighten the tensioner bolt to 23 ft. lbs. (31 Nm).
  11. Install the timing covers.
  12. Install the accessory drive belts.
  13. Connect battery negative cable.
Hope this helps.
