Hi there:
In most cases when the serpentine or drive belt keeps breaking it’s due to one of three issues. First, the belt is either too tight or too loose when it’s installed; which is typically caused by a drive belt tensioner pulley that’s damaged. Second, would be a damaged of faulty drive pulley. Finally, it’s possible that the belt is installed sideways or not straight, which will cause excessive heat to build up on the belt itself and possibly shred. Check all three of these items and if you can’t determine why you’re having this issue, please feel free to contact a professional mechanic to diagnose or repair this issue for you.

Slipping can be the result of a loss of belt tension (or a weak automatic tensioner) or pulley misalignment. When the belt slips off the track, the friction between the belt and accessory drive pulleys causes the belt to overheat. If you hear a high pitched squealing noise, it`s probably time for a switch.
95% of the time, frequent alternator or serpentine belt breakage is caused by either faulty pulley`s or misaligned or un-properly adjusted belts.
If the belt is too loose or slips this could force the engine to stall or shut down. This could be very dangerous if the car is on a busy road or motorway. i The car battery is dead. If the issue is severe, the battery will not be able to maintain its charge and could die shortly after the car has been started.
A worn-out belt will affect the engine`s timing, and possibly cause it to misfire. If the belt is worn or loose, it will slip and cause cylinders to open and close earlier than they should. If this timing is off, the engine will run erratically, if it runs at all.
A broken or seized pulley can quickly lead to a torn belt, or in less serious cases, the belt falling off of the engine. An engine without a belt can quickly run into issues such as overheating and stalling, as it`s the drive belt that allows the engine accessories to function.
The primary distinction between tensioners and idler pulleys is the presence of an adjustable bolt. Tensioners are positioned on the bolt through mounting. Idler pulleys are not mounted to an adjustable bolt.
Driving with a bad belt tensioner is unsafe since the tensioner is meant to guarantee ample tension that powers accessories. Wear on the belt tensioner will eventually cause the belt to slip, generate loud noise, and also create an unsafe level of heat along the accessory pulleys.
If the pulley is damaged, replace the tensioner assembly not just the pulley. If an idler pulley is damaged, inspect the tensioner also because vibrations caused by a bad idler pulley may damage the tensioner.
Improper belt tension is the most common and obvious cause of slip, which generates unwanted heat. The friction that occurs when a V-belt slips in a pulley causes belt sidewalls to become glazed, and decreases gripping ability.
It`s quite simple, really: your car cannot run at all without a timing belt. If the belt breaks while you are on the road, the car will break down immediately – and your engine can experience severe damage.

Replaced alternator on car 2 times each time shows it’s charging 14v let car run for a little bit then test drive and car voltage
ANSWER : There are reports that the replacement alternators will not communicate with the engine computer and will not charge correctly. I recommend using only the manufacturer approved replacement part. It can be new or remanufactured but approved for use in the vehicle. Some lower cost alternators on the aftermarket will have charging problems since they will not communicate with the ECM on the vehicle and will stop charging.

I had a new serpentine belt and pulleys put on my car but the belt tends to keep popping off,
ANSWER : The serpentine belt need constant tension on the belt to keep it from coming off. If the belt alignment is not aligned then the belt may come off. The tensioner may be out of alignment and not putting enough tension on the belt. Have a mechanic check the tensioner and replace it if needed.

I put the wrong key in my car and a few weeks later my car just shut down and it will not start I believe it’s the computer but…
ANSWER : Hi there. What had happened is the wrong key set the security to the vehicle. This is to prevent the vehicle from starting with the wrong keys. Try removing the battery cables (+) and (-) for 13 minutes. During that time, put the original key in the ignition and turn it on. Activate everything in the car even though there is no power. Then remove the key and hook up the battery cables. The computer should have reset and reset the security. If the security is still being tripped, then I recommend seeking out a professional, such as one from Your Mechanic, to help you

Old belt was sqeeking, new belt does not but it slips off constantley. The old belt stays on though. Why is this?
ANSWER : Check to be sure that the new belt is actually the right part number or, better yet, use an OEM (dealer) belt. Also, be sure the tensioner is the right part number or use an OEM sourced tensioner. Check to be sure that all of the pulleys and accessories (e.g., alternator, water pump, A/C compressor) that are driven by the serpentine belt are all operating in the same plane. It is not unusual for the pulley on the crankshaft harmonic balancer pulley to move (generally outward) relative to its original position. The pulley is rubber bonded and over time can move. If that pulley moves, that means that the belt groves are no longer running in a perfect plane and that alone can cause slipping. If you request serpentine belt inspection a certified Mechanic, dispatched by YourMechanic right to your location, will identify the problem and thence get the issue resolved for you promptly. If you have further questions or concerns, do not hesitate to re-contact YourMechanic as we are always here to help you.

Serpentine belt tearing apart by pebble & pieces of it getting inside timing belt, motor destroyed
ANSWER : Hi there. I agree with you – this doesn’t pass the ’smell test’. The only way for debris to enter the engine is through the throttle body. Since the throttle body inlet is protected and covered by an air intake on your Ford Fiesta, I highly doubt that this is the source of your problems.

My car cranks but will not start. I try to do fix the car myself. I put new battery, new alternator, and new ignition coils.
ANSWER : Hi there. Check the spark plugs and see if they are worn or burned. If the plugs are good and they have a good spark, then the engine compression could be low causing a no start situation. If the spark plugs are not emitting a spark, then the crankshaft position sensor could have failed or disconnected. Check the crankshaft position sensor wiring harness and make sure that its plugged in. Check the sensor and make sure that its not broken or damaged. If you need further assistance with your engine not starting, then seek out a professional, such as one from Your Mechanic, to help you.

my car got a new fuel pump in saturday and when i cranked my car it started put putting and immediately cut off… whats the prob?
ANSWER : Hello there, thank you for asking about your 2004 Kia Amanti. There are a couple of other things that can cause your symptoms. A failing engine speed sensor like a crankshaft position sensor can cause the vehicle to stall when it fails and can interrupt engine operation intermittently. If your sparks plugs are very worn out, the vehicle may idle smoothly or rough and stall when you try to accelerate. Avoid an unsafe driving situation. If you need help, a certified technician from YourMechanic can replace the crankshaft position sensor and spark plugs at your home or office.
