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 hour—two 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.
Can I change the timing belt on my own?
It does need some engine knowledge to replace a timing belt and water pump, so if you don’t have much expertise working under the hood, we advise leaving it to the experts. However, if you prefer making your own repairs and restorations, you can do it yourself and avoid paying hefty repair expenses in the process.
Starting with the tools you’ll need, we’ll walk you through the replacement of a timing belt and water pump step by step.
What You’ll Need to Replace the Water Pump and Timing Belt
- leather gloves
- Wrench socket set
- tools for driving screws, such as Philips and slot drive
- bags made of plastic and a permanent marker (for labelling nuts, bolts and parts you remove from the engine)
- Set of Allen keys
- jar or bucket (for collecting coolant)
- new antifreeze/coolant
- Tip-Ex, white chalk, and white paint (for marking the cogs for simpler reassembly)
- a fresh timing belt
- a fresh water pump
Step 1: Preparation
Get your car and work area ready first. Depending on your degree of experience, changing a timing belt and water pump can take anywhere from one to three hours, so make sure you have the time and space necessary. Before you begin, carry out the following:
- To reach the undercarriage beneath the engine, jack up the front of the automobile.
- To stop the engine from spinning while you’re removing the timing belt, put the engine in drive and use the handbrake.
- Since coolant will spill out when you remove the water pump, place a bucket underneath it. To find the pump, see your car’s manual.
- Before starting, make sure the engine is entirely cool.
- Prepare all of your tools, and have bags and a pen on available to name and store the engine parts you remove.
Step 2: Removing the Belts
You must first remove the fan belt and power steering belt because they are located next to the cover that protects the timing belt and water pump. To remove the belts, take the following actions:
- The fasteners holding the alternator in place should be loosened. The fan belt can then be removed by lightly tapping it.
- To access the timing case and crankshaft pulley, do the same with the power steering belt by moving it aside.
- Crankshaft pulley: Loosen. To access the engine and remove the bolt, you’ll need a long wrench arm.
What are the warning signals of a failing timing belt?
Your timing belt may be significantly damaged if you hear a ticking sound emanating from the engine of your car. Your car’s timing belt is connected to the crankshaft and camshaft of the engine through a number of pulleys. The connecting rods of the engine, which are connected to the pistons inside the combustion chamber, provide power. The rocker arm assembly and cylinder head valves are controlled by the camshaft, which delivers gasoline to the combustion chamber. The exhaust manifold is the next point of exit for the released gases. Your car’s timing belt may start to twitch inside the engine when it begins to wear out. This can potentially be a symptom of low oil pressure.
Does a timing belt failure damage the engine?
First of all, how could you possibly predict when your timing belt will fail? Your car cannot function at all without a timing belt, which is really fairly basic. The automobile will quickly break down if the belt breaks while you’re driving, and your engine could sustain extremely catastrophic damage. In order to take action before it is too late, you need to be on the lookout for warning signs and symptoms of a weakening timing belt. These include your engine making loud clicking or screaming noises, misfiring, and not starting at all.
How much time can a car operate without a serpentine belt?
The answer to this issue depends on a few different variables, but generally speaking, your automobile should be able to run for 20 to 90 minutes even with a broken serpentine belt.
On a hot day, the engine will overheat more quickly without a working cooling system, reducing your window for driving.
However, if the temperature is cold and your battery is completely charged, you might be able to operate the engine of your car for a little bit longer than 90 minutes before the battery runs out. That may be sufficient time to reach a close-by mechanic.
To prevent battery drain, all electrical and electronic equipment should be turned off. Also, keep in mind that your steering wheel will feel somewhat heavier.

Serpentine belt: Does it impact the transmission?
Your car’s transmission may sustain damage if the serpentine belt ruptures. The engine will start to overheat almost immediately after the serpentine belt in your car snaps. The water pump can’t sufficiently cool your engine if the belt isn’t moving. Your transmission could sustain damage if the engine overheats.
Without a serpentine belt, can you drive?
If you’re wondering if you can operate your vehicle without a serpentine belt, the answer is categorically no. You should never operate a car without a serpentine belt because it performs the crucial job of transporting antifreeze to critical engine components. The water pump is driven by the serpentine belt, and without it, there wouldn’t be enough coolant flow to keep the engine from overheating. It’s also crucial to keep in mind that the power steering pump is driven by the serpentine belt. The power steering pump, which generates hydraulic pressure, is inoperable without the serpentine belt. As a result, turning the steering wheel will be challenging, if not impossible.
Is it simple to replace a serpentine belt?
It only takes a few simple steps to replace a serpentine belt: thread it into place, turn the tensioner, and slide the belt over the nearest pulley on top. The majority of belt tensioners use spring tension. The spring maintains pressure on the belt after installation.
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.
Are serpentine belt and alternator belt interchangeable?
The serpentine belt, which is also known as a fan belt, alternator belt, or accessory drive belt, is spun by the engine crankshaft and in turn “drives” or spins the accessories. In the past, there were several drive belts used in cars, but today’s models (mostly) only use the serpentine belt.
Serpentine belts: do they produce noise?
A noise coming from a freshly installed serpentine belt indicates an issue with the engine’s front end drive system. Serpentine belt noise is the belt drive system’s equivalent of a “check engine light,” signaling a problem. Surprisingly, the belt is not the main offender most of the time.
How much does a Nissan Altima timing belt cost?

Do I need to change the timing belt and water pump?
Many modern engines now use timing belts instead of timing chains. The appropriate sequential operation of the crankshaft, pistons, and valves is guaranteed by both belts and chains. Compared to chains, belts are more efficient, lighter, and quieter.
Unless your vehicle has a time chain, which doesn’t often need repair, both parts are essential to the vehicle’s correct operation and should be replaced on a regular basis. See how these parts function below, along with information on the internal parts of the timing belt and water pump system that are related to them.
For information on when to replace your water pump and timing belt, consult your owner’s manual, or stop by and speak one-on-one with one of our service specialists. In general, whenever the timing belt is changed, the idler pulleys, tensioner, and water pump should also be replaced. Since the water pump is often driven by the timing belt, now is the ideal time to replace it. In addition, the manufacturer advises it.
A WORD FOR THE SMART. When requesting a “over-the-phone estimate for replacing a timing belt and/or water pump,” use caution. Less reputable businesses will offer you what appears to be a wonderful price to entice you in and not disclose the “full picture” (see above). The vast majority of the time, it is cost-effective and complete maintenance to replace the timing belt, water pump, tensioner, and idler pulley (where equipped) all at once. This is because, if one element needs replacement, the others are typically not far behind. For details, consult your owner’s handbook.
