What does this cost in your state?
California is the costliest state and Arkansas the cheapest; each square shows that state's midpoint of the estimate.
Lower-cost states ($156)MiddleHigher-cost states ($199)
What it shows: CA is the highest at $199 and AR the lowest at $156, across 51 states.
Counts below are complaints filed with NHTSA, not failure rates: a longer bar means more owners reported it.
Is your car affected?
What it shows: The most common band for complaints about this repair is 6-9 years (35%), against 23% for all complaints: the biggest difference between the two.
Is it urgent, and what do owners notice first?
113 owner complaints name this part.
Owners say the dealer could not fix or repeat the problem. If it comes back after a repair, ask what was tested before you pay again.
How fast were owners driving when it happened?
55 mph or faster leads at 49%.
Owners reported it most often at highway speed. Tell the shop what speed it happens at, because that narrows the diagnosis.
How serious did it get for owners?
Among the 113 owner complaints naming this part, being towed is the outcome owners report most often.
What it shows: Towed is the largest at 11, followed by Fire reported at 5; the smallest shown is Crash reported at 2.
Which model years show up most in the complaints?
Among the 113 owner complaints naming this part that state a model year, complaints cluster in a few model years instead of spreading evenly.
What it shows: 2015 is the largest at 21 (19%), followed by 2016 at 13 (12%); the smallest shown is 2024 at 1 (1%).
Has the maker published a fix?
A bulletin is a repair procedure a maker sends its dealers, not a safety defect: if your maker is listed, ask the dealer whether one covers your car and quote its number.
| Maker | Vehicles | Bulletin number | Date | What it says |
|---|---|---|---|---|
| Chrysler | Pacifica 2022–2023; Voyager 2022–2023 | Reference47A1 | Aug 3, 2023 | Customer satisfaction notification 47A - serpentine belt. |
| RAM | 3500 2019–2023; 2500 2019–2023 | S2109000011 | Jul 26, 2023 | Squeak, chirp, or tick noise from the serpentine belt area. |
| Chrysler | Pacifica 2023 | 0900423 | Feb 2, 2023 | Incorrect Serpentine Belt and Tensioner This bulletin involves inspecting and if necessary replacing the serpentine belt and tensioner pulley. |

What do owners say?
2 complaints quoted word for word, each with its NHTSA number.
While driving at highway speed, the factory-installed serpentine belt on my 2023 Chevrolet Express 3500 (6.6L V8, approximately 24,000 miles, purchased new, factory-maintained per schedule) failed suddenly and without warning.
The serpentine belt was busted, info on it says it should 5 years or 100k miles.
Check your car
Our calculator's default estimate is $135–$225 for one aftermarket belt, parts plus labor. Three choices move that number most: whether the tensioner and idler pulley are replaced with the belt, how many drive belts your engine has, and whether a chain shop or dealership does the work.
What does the serpentine belt price cover?
The estimate covers one belt and the labor to route it and set the tension. That is the whole job on most cars: take the old belt off, check the pulleys by hand, fit the new belt and run the engine.
It leaves out what a shop may add. A worn tensioner or idler pulley is a separate part, and a quote that quietly includes a kit can look far above the default. Towing, taxes and local labor rates are not included either.
How much does the price change by setup and shop?
The parts you add move the total more than the shop does. Here are the calculator's ranges by setting.
| Setting | Estimate |
|---|---|
| Default: one aftermarket belt | $135–$225 |
| OEM (dealer original) belt | $163–$273 |
| Belt, tensioner and idler pulley kit | $235–$465 |
| Two separate drive belts | $210–$353 |
| Economy car | $110–$200 |
| SUV or truck | $163–$273 |
| Luxury or performance car | $170–$330 |
| Chain shop or franchise (about $120/hr) | $151–$251 |
| Dealership (about $175/hr) | $195–$323 |
Each row changes one setting from the default. If your car is a truck or luxury model, start from that row, then add the kit row if the shop wants the tensioner done too.
How do I know it is the belt, and how urgent is it?
A squeal or chirp from the front of the engine, especially on a cold start, points at the belt. Cracks, glazing or a frayed edge you can see with the hood open do too. A belt that has already snapped usually takes the charging, power steering and cooling help with it, so the car will not go far.
A noisy belt is not an emergency, but it is a short fuse. If it is squealing or cracked, book the swap this week rather than waiting for it to break. If the dash warns of charging or temperature trouble, stop driving and get it towed.
How do I get a fair quote?
Call a few shops and give each the same details: year, make, model and engine. Ask whether the price is for the belt alone or includes the tensioner and idler pulley, and ask which brand of belt they use.
Compare like with like. A low quote for the belt alone is not a deal if the pulleys are worn and the shop will have you back. Ask the shop to show you the old belt and say what condition the tensioner and pulleys are in.
What does the estimate leave out?
It is a range for a typical car, not a quote for yours. Belts that are hard to reach, or an engine that needs other parts moved first, take more labor. A seized or noisy pulley found during the job turns a belt swap into a kit job.
If a quote lands well above the range for your setup, ask what is being added before you pay. The next step is to enter your car in the calculator above and take that range with you.
Frequently asked questions
Can I replace the belt myself?
Many owners do on simple layouts, and the calculator shows a parts-only DIY range for each setting. Take a photo of the belt routing first, because the wrong routing is the common mistake.
Should I replace the tensioner with the belt?
If the tensioner or an idler pulley is noisy, loose or wobbles, yes, because a worn one wears out the new belt. If they spin smoothly and hold tension, the belt alone is the fair comparison.
Does the dealership always cost more?
Its labor rate is higher, so the total is higher. The gap is smaller than the jump from adding a tensioner kit.

What is our own estimate
The price range comes from our calculator's formula. Its parts prices, labor hours per job and shop-rate tiers are CalcScrape estimates, not a published price dataset. Checked against RepairPal's range ($154–$212) on 2026-10-04: our default's midpoint is 2% below the middle of that range. Methodology
