Can I change a serpentine belt on my own?
Since automatic belt tensioners are now common in most cars, changing a serpentine belt is a straightforward do-it-yourself fix. You may complete the project in 15 minutes if you follow the step-by-step directions and detailed pictures.
What about the Toyota Yaris’ serpentine belt?
Serpentine belt replacements for Toyota Yaris typically cost between $59 and $72. Between $38 and $48 is the expected cost of labor, while between $21 and $24 is the estimated cost of parts. Taxes and other fees are not included in this range, nor are your particular model year or geographic area taken into account.
How long does a serpentine belt replacement take?
The length of time it takes to replace a belt depends on your car’s model and how easily it is reached.
A damaged serpentine belt can be fixed or replaced with a new belt in as little as 15 minutes and as much as an hour.
Warning Lights on dashboard
Warning lights on your dashboard are the first thing you might see if your serpentine belt is damaged or entirely snapped off. The serpentine belt drives the alternator, and if it breaks, the warning light will come on, so it’s likely that you’ll see the battery light.
Other warning lights, such as a power steering or hydraulic pressure warning light, might also be visible.
Heavy steering
The power steering pump is often driven by a serpentine belt in vehicles. In the event that your serpentine belt fully snaps off, the power steering pump will no longer function.
If it is not working, you will notice it because the steering gets extremely heavyso heavy that it could be deadly.
However, the majority of contemporary vehicles do have an electric power steering pump, therefore in this situation, you won’t experience heavy steering caused by a broken serpentine belt.
Cracked serpentine belt
The most obvious sign of a defective serpentine belt is when the belt begins to fracture. Examining the belt will frequently allow you to see this clearly. Even if the belt is not totally worn out, some cracks may appear fairly quickly, but if the belt has many cracks, it should be replaced.
Squealing sounds
You can hear squealing sounds coming from your serpentine belt if it hasn’t snapped off yet but is starting to deteriorate. This happens more frequently when the belt is under load, such as when you steer, which requires the power steering pump to operate.
Start a variety of electronic consumers, such as the heating, radio, and headlights, to test this. The alternator will have to work harder as a result, and if you hear higher screaming, your belt may not be in good condition.
Serpentine belt tensioners are often automatic in current automobile models, but manual tensioners may be present in certain older cars, so you may need to tension the belt manually to get it right and stop squeaking.
Why is the Yaris in my Toyota squealing?
The engine bay of some 2007 Yaris cars could make a screeching noise. Toyota claims that the serpentine drive belt slipping on the various pulleys is one potential source of the noise.
The squeal should stop after replacing the drive belt with part number 90916-02500, an improved design belt, and tightening the belt in accordance with updated specifications.
Installing the new belt will begin the repair. After stretching the belt for around 20 minutes, start the engine and then turn it off.
Place a belt tension gauge in the span illustrated in the aforementioned figure and tighten the belt until the tension gauge reads 102-123 ft-lbs.
Simply measure the belt’s deflection in the span region of the figure if you don’t have a tension gauge. The belt should deflect after being appropriately tightened. 410-.450 inches.

How many belts are there in a Toyota Yaris?
The accessories in or on the engine of your Toyota Yaris are powered by the drive belt(s) by using the engine revs. Your alternator, water pump, air conditioning compressor, and power steering are a few examples.
Most Toyota Yaris models feature one or two drive belts, which are sometimes referred to as serpentine belts. The belt can be formed of perishable materials like rubber, neoprene, or urethane and must be flexible to move over pulleys.
The driving belt belt(s) are tensioned and mounted on pulleys. This secures the belt in position and supplies the attachments with the energy they need to function properly. The accessories’ performance could suffer or cease entirely when the belt begins to wear, is damaged, or breaks.
Drive belts for Toyota Yaris vehicles should be changed as necessary or at the predetermined service period as specified in the service manual. Drive belts occasionally get damaged or need to be replaced earlier than anticipated, thus it’s advised to check them at every service.
Depending on the sort of drive belt(s) being replaced and whether additional engine parts need to be taken out to gain access, the cost to have a Toyota Yaris drive belt(s) replaced ranges from $100 to $400+.
When the drive belt tension has changed and it has to be replaced or rebuilt, you may occasionally hear a noise warning. Your drive belt may be signaling that it requires maintenance if you hear screeching during or shortly after vehicle starts.
When should a Toyota Yaris timing belt be replaced?
Although they can last up to 100,000 miles, it’s always a good idea to change them before that. The valves, pistons, and other internal engine components can sustain significant damage in the event of a belt failure.
How much does a serpentine belt replacement cost?
A common serpentine belt costs no more than $75 and starts at about $25. You could change the belt yourself if you have a basic understanding of auto repair, which might save you between $75 and $120 in labor costs. You should budget between $100 and $195 to replace your serpentine belt altogether.
The straightforward fix for this issue shouldn’t take more than an hourtwo at most. It depends on the car’s model and how simple it is to access the serpentine belt inside the chassis of the vehicle.
What occurs if a serpentine belt snaps while you’re driving?
Alternator belt, fan belt, and auxiliary drive belt are further names for the serpentine belt. It is responsible for giving power to crucial systems, including the electrical system, the power steering system, the cooling system, and the A/C system. It is powered by a car’s engine to spin or “drive various mechanical components in the engine. The serpentine belt is also necessary for the power brakes, radiator fans, and water pumps in some automobiles.
When an engine accessory’s ability to spin at the right speed is compromised, such as by wear, contamination, or a broken serpentine belt, the electrical system’s output is reduced. This may result in an abrupt loss of power assistance for the steering system, making the steering wheel suddenly difficult to turn. The water pump’s ability to circulate coolant throughout the cooling system may be impaired by a damaged serpentine belt, which could lead to the engine overheating. Additionally, it may prevent the alternator from producing energy to run the car’s electric and electronic systems and recharge the battery, which will cause the headlights to dim, the radio to cease working, and the battery to die.
How long does a serpentine belt on a Toyota last?
A serpentine belt can endure between 50,000 and 100,000 miles since it is made of sturdy rubber. Learn more about serpentine belt replacement timing from Westbrook Toyota’s service department.
If the serpentine belt fails, can you still operate a vehicle?
A automobile must be towed if its serpentine belt breaks, rendering it undriveable. Without a serpentine belt, the engine may overheat because the water pump won’t function. Other components can be harmed by a damaged belt.
What is the sound of a worn serpentine belt?
Belts called serpentine belts join the pulleys in your engine. These belts often link the alternator, water pump, power steering pump, and air conditioning condenser to the crank pulley. Different cars have different numbers of pulleys, depending on how your engine was built. All of these essential pieces can be driven by the engine’s rotation by connecting them to the crank pulley.
These belts may start to squeak or screech as they deteriorate. They generate noise when the belt is not tight enough or when the pulleys are weak or out of alignment. Often, all it takes to stop the screeching is to change the belt. Despite seeming terrifying, the noise rarely poses a threat. It may occasionally be a clue that the belt is going to break. It’s recommended to routinely check your belt, particularly if it starts to make noise.
You shouldn’t put off checking your serpentine belt until it starts making noise. Check your belt every time you check your oil. Look for fraying at the edges with particular attention. Replace the belt right away if you see that it is starting to fray. A belt that is fraying indicates that it is really worn out and may break, leaving you stuck. The same holds true if you notice any unusual cracking. Serpentine belts break over time as a result of being heated and chilled. If your belt breaks due to a crack, you can be stuck waiting for a tow truck. Your belt will deteriorate over time even if it is not frayed or cracked. Make sure you change your vehicle’s serpentine belt according to the specified service frequency.
Although not as frequently as other parts like filters, belts need to be replaced. It might need to be replaced once every five years or 50,000 miles, depending on your car. In many cars, the belt only has to be changed once every 10,000 miles. If you are aware that your serpentine belt is older, it is crucial to monitor it because older belts are frequently weaker.
