Hello Alexis,My name is Andres and i will help you with the problem that you are having There is no tensioner per se on the 240. The tensioning is done by moving the alternator. At the top of the alternator there is a tensioning arm with an elongated hole in it. There is a square necked screw which goes through the arm and fastens to the alternator. At the end of the arm there is an adjusting screw. As you are removing the alternator forget about the adjusting screw. Slacken the nut on the square necked screw and push the alternator to the side, releasing the tension. If the alternator won't move, loosen the flange screw underneath the alternator until it will. With the belt off remove the wires from the back of the alternator, making sure you know which goes where. Remove the two bolts you have loosened and remove the alternator. HAVE IN MIND THAT There is a problem on the older 240 series, 1984 B23F I know from personal experience, with the ground not being intact between the alternator and the metal grounding point. Please check the wiring loom before you re-install your new alternator for a good grounding wire, or you'll be wondering why your Swede won't crank when you've just replaced the alternator. If worst comes to worst, you can create a temporary ground for the alternator with a piece of copper wire. Connect one end to a good unpainted ground near the alternator(strut towers will do), and the other to the attachment bolt on the alternator mounting bracket itself. This will suffice until you can get it properly fixed

How to remove belts from 1994 dodge caravan 2.5 liter


Drive Belts

Print


INSPECTION

See Figures 1, 2, 3, 4 and 5
Check the condition and tension of all drive belts every 12,000 miles, or at least once a year. Loose drive belts can lead to poor engine cooling and diminished alternator, power steering pump, air conditioning compressor, or emission air pump output. A belt that is too tight places a strain on the bearings in the driven component.

Fig. Fig. 3: Deep cracks in this belt will cause flex, building up heat that will eventually lead to belt failure

Fig. Fig. 5: Installing too wide a belt can result in serious belt wear and/or breakage
Replace any drive belt that is glazed, worn, cracked, or stretched to the point where correct adjustment tension is impossible. If two belts are used to drive a component, always replace both belts when replacement is necessary. After installing a new belt, run the engine for ten minutes, shut OFF the engine and recheck the belt tension. Readjust if necessary.

Fig. Fig. 10: Engine belt tension chart-1994-95 models
Two popular methods of checking drive belt adjustment are; the Belt Tension Gauge Method and the Belt Deflection Method. The former requires a special gauge and the latter requires a straight edge and scale or just a good eye for measurement. The deflection method will be used in the following belt replacement instructions. A rule of thumb for checking belt tension by the deflection method is to determine the midpoint between two pulleys of the drive belt and press down at that point with moderate thumb pressure. The belt should deflect to the measurement indicated in the following installation procedures. Adjustment is necessary if the belt is either too loose or too tight.

WARNING A belt adjustment which is either too loose or too tight will eventually damage the accessory that belt is driving. A too loose adjustment allows free-play in the belt which could transfer a whipping motion or shock to the accessory drive pulley. Similarly, a belt which is too tight will preload the accessory bearings, leading to early failure.


REMOVAL & INSTALLATION

See Figure 11
Raise the front of the vehicle, support on jackstands and remove the lower splash shield if access is hampered due to space limitations when changing drive belts.

I need to replace the alternator belt on a 1994 Volvo 940T, but can't get the A/C belt off so I can remove the alternator belt. Apparently there's an adjustment bolt on the compressor that I...


Hi,
Unscrew the idle pulley first.
Look for a small pulley where the a/c belt passes through. That is the idle pulley, the screw on the bracket of that idle is on the top side where you could adjust to loosen the tension of the belt. Before loosening it, loosen the bolt on the front of idle pulley.
Hope FixYa helps you out!

Steering wheel shakes when the Aircon unit is on but if the Aircon is off it seems okey. pls advised.


First, check the level of your power steering fluid and top up the level if low. Then adjust your serpentine belts. A loose belt may be causing the the steering wheel. To adjust your alternator belt . First , take off the negative battery cable so you do not blow an expensive fuse on the positive battery cable clamp. Facing the back of the car, reach UNDER the alternator and loosen the bolt on the bottom right side, now loosen the bolt on the adjuster block on top, you can now turn the adjuster bolt and move the alternator to change or adjust the belt.
To take off or adjust the steering pump belt on the front of the motor, you need to loosen the nut on the back side of the adjuster pulley (right side ,belt is on the left) . With the adjuster pulley loose , you can use the adjuster bolt to move the pulley forward and backward to adjust the steering pump belt tension

Need to tighten alternator belt


The alternator is held in place by two bolts.

Top and bottom bolts - 12 mill bolts.

By loosening the bolts (especially the top bolt) you will find that the alternator can be manipulated forward and backwards alongs it housing (guides). To tighten the alternator belts all you need to do is push the alternator away from the tensioners and tighten the belt as required.

Once the belt is taut, but not stetched, simply tighten the two bolts up again and check that the belt has not lost its tension when you where tightening the belts.

How do you adjust tension for drive belt


first you need to figure out if you have an automatic tensioner or an adjustable one. so look at the pullies which ones are not accesories (ie not an alternator pully, power steering.) some pullies will just be on there own not driving anything. is this pully connected to something like this O>o <--this end is the pully.
pully mounting bolt ^ ^arm with hole for rachet
or does it look like the pully is attached to a threaded pole.

the auto adjuster need a rachet to pull back on it (because it's spring loaded) while you install the new belt.

the other need the nut on the pully loosened and the threaded pole loosened will move the pully removing tension from the belt (opposite will tension the new belt).

tighten belt until you can only twist it in half.
