Serpentine Belts

The belt diagram for a 350 Chevy engine can vary depending on the specific model and year of the engine. You can refer to the vehicle's owner's manual for the correct diagram or consult a service manual for your specific vehicle. Alternatively, you can search online for the specific belt diagram that matches your Chevy 350 engine.

No, if the air compressor is locked up, replacing the serpentine belt will not allow the engine to run smoothly. The locked-up air compressor will put strain on the engine, causing potential damage and affecting its performance. It is recommended to address the issue with the air compressor before attempting to run the engine.

Most vehicles have a factory sticker under the hood showing this. If not, try checking the owner's manual, or contact a dealer service department. They should be able to provide a photo copy of this...usually for free.

Moisture from the rain can cause the belt to slip against the pulleys, creating a squealing sound. This can happen if the belt is worn, loose, or if there is a misalignment in the pulleys. It's best to have the belt inspected and potentially replaced by a mechanic to prevent further issues.

A belt diagram for a 1985 Mercury Topaz can be found in the maintenance manual of the car. Sometimes, there is a sticker on the car with the diagram, and an auto shop might print a copy of the diagram for the person.

Rotate means to turn. Counterclockwise=Opposite direction a clock turns. They are probably talking about rotating it on the pulley in order for it to mate correctly. Just put it back on exactly as the diagram shows. Inspect the idler to see if it is good. If not replace it.

This shows pics for replacing an alternator but requires removing the serpentine belt.

the belt tensioners are on the alternator and the air conditioner. On the alternator, you would have to loosen the 2 bolts that are on the tension bar. On the air conditioner, you would have to loosen the tension bolt and you would also have to loosen a bolt that is behind the air conditioner pulley. You would have to turn the pulley to get the holes to line up to the bolt to loosen.

write down how the belt is currently installed loosen the tensioner with a 15 mm socket it is the last pulley on the far bottom left you must remove the passenger wheel and splash guard to get to this pulley after you loosen the pulley pull the belt off put on the new one in the same order i go over the alternator last usually make sure the belt is on all pulleys tight and off you go it is easier to get the belt on with 2 people time .5 - 1 hour

1) Rotate drive belt tensioner mechanism upward, away from drive belt using a 1/2 inch breaker bar. 2) Remove serpentine drive belt. 3) Reverse procedure to install.

Most cars and trucks today have what is called a serpentine belt which runs most accessories.They are very dependable and usually easy to replace. To decide if your belt needs replacing, simply look at the grooved side of the belt to see if it is cracking badly. A couple of cracks every 3 inches is normal, but if you see cracks every 1-2 inches I would recommend that you replace it. On most cars and trucks the procedure is basically the same. First off, get the correct belt by bringing your cars VIN number to the parts store(located on your cars dashboard) the parts store may need it. If there are two choices, get them both so you can complete the repair. Once you have the correct belt, take a minute to review how the belt runs across the pulleys and also check to see if your car/ truck has a underhood diagram of belt routing in case you need it. In most cases you will need a socket wrench or breaker bar with either a 3/8" and /or 1/2" head on it and possibly a short extension. Some models may require a wrench of these similar sizes.Now that you are ready to go to work, you will need to find the spring loaded tensioner which is generally located near the top of the belt path; it usually has a shinny pulley on it. Look at the tensioner and insert the tool into it and apply opposing pressure to release the belt.Now, simply install the new belt making sure it fits into the grooves on all the pulleys. Start the car to check it and you are done and you saved yourelf some money!

it means you need a new belt...plain and simple....lots of people keep driving on their cars when a belt squeaks..and allit does is lead to other problems..... i am no expert, but i think it is the Drive belt that is squeaking

If your vehicle has an automatic belt tensioner with a serpentine belt, the belt is worn and needs to be replaced. On older models, the belt tension can be set by adjusting it at the alternator bracket. Loosen but do not remove the two bolts that hold the alternator in place (one at the bracket and one on the block) and pull the alternator to tighten the belt. Hold in position while re-tightening the bracket bolt then tighten the bolt on the block.

However, be aware that the 15mm nut on the automatic belt tensionner must be turned counterclockwise to release the tension on the belt. Not much torque needed when correctly performed. When working from above the belt should be monted on all flywheels except the idler pulley. Whilst turning the belt tensioner (counterclockwise) push the belt down under the idler pulley and release the torque on the tensionner nut to complete the installation.

It depends on whether you have the self-adjuster or not. Without the adjuster the steering pump needs to be loosened at the three bolts that hold the pump to the bracket. The bottom bolt is the tension adjuster. With the self-adjuster, you need to rotate the adjuster towards the engine to slip the belt off. Once the belt is off the tensioner it will move out of the way. Be prepared to use a block of some type to hold the tensioner so it won't hit the battery case. The nut on the tensioner is a 15mm size

Also, once you have the belt off, be very sure you put the new one on the right way. There should be a sticker on the engine cowl that shows you how the serpentine belt should route around the engine pulleys. Once you have it routed right, make sure you tighten everything very tight, making sure you have put enough tension on the belt. This is usually a tough part of the process because you need to get the tension against the adjusters, which keep the belt tight as it moves

Hey Duane==I think I use a wrench on the bolt that holds the pulley to the bracket for the idler. I think it is 13mm. Goodluck, Joe

There are 7 pulleys to put it over or under on the 4.0. The ridged side of the belt goes on the ridged pulleys, the smooth side of the belt goes on the smooth pulleys. The ridged side is 'inside' the loop made by the fan. So starting on the left (facing the truck) The upper left corner pulley (AC Compressor) OVER Directly under that, low, the alternator UNDER OVER the fan UNDER the motor INSIDE the tensioner OVER the power steering pump UNDER the water pump Another way to put it: So the two large, center pulleys are the water pump and the motor. It is on the bottom of both of these. The top two on left and right, respectively are the AC Compressor and the power steering pump. it is on top of these. The remaining two pulleys are on the left; a small one low is the alternator which the belt runs on the bottom. The other is the fan which the belt runs over the top. Make sure the tensioner pushes the belt IN TOWARD THE WATER PUMP as you tighten it.

The diagram for replacing a serpentine belt for the 1991 Jeep Cherokee Laredo is located on the front of the vehicle inside the engine compartment. You can also find this diagram in the Chilton's manual for this vehicle.

most auto parts store carry manuels on most cars just find the one that is on your van and a diagram of how the belts go on will be in it. the books cost around 15 dollars to buy but some store will let you look at them.

If you've got a 4.0 litre engine than you've got a Automatic belt tensioner on the engine. Sits to the right of the alternator. If your belt is loose, than you need to check that the belt is on properly on all the pulleys, or if you have the right belt. If the belt was made for a motor with A/C and yours doesn't have that, then the belt will be to long. Check with your local auto part supply store. Hope this helps...... For info on how to route the belt, get a chiltons manuel and it will have a diagram.

The alternator, water pump, power steering pump, air conditioner and possibly the air pump receive power from the serpentine belt.

The belt is held in place by a tensioner. it looks like a flat pulley with nothing attached.it has a nut on top that is used to release the pressure on the belt. It is a good idea to get the tool that is needed to do the job. it can be done with regular mechanic's tool. If there is space to use them. make a drawing of the belt pattern before you do anything. it make it much easier to put back on. i made that mistake. Take what ever tool you are going to use and slowy turn the bolt counter clockwise. you should be able to see the tension on the belt release. Slide the belt off of one of the components, and return the tensioner to it original place. notes. the tool needed is not expensive, and can be found at most parts stores. also replace the belt with one that is the same as the one you removed. some have anywhere from 4-7 grooves. hope it helps. duboff

It depends on the engine and if you have A/C. Check out greatlakesxj.com/tech.html for the maintenance manual. Belt routings are on pages 939 and 940. Please be sure to leave a small donation so that they can maintain the website.

Almost every car and truck since 1980 has a belt routing guide on a sticker under the hood. This is most often placed on the radiator shroud or radiator mount but can be found other places like on the bottom side of the hood. If the sticker is gone then go to your local automotive parts dealer like NAPA and ask them to please look it up for you. A nice counter guy - or girl- would be happy to check their books for you and hand you a print out. Be sure to have the make, model and engine info with you. Mitch
