Timing Belt Replacement Cost (2026): Belt vs Chain, by Car

Replacing a timing belt costs $500–$1,100 at a US independent shop in 2026, and $700–$1,300 with the water pump done at the same time. The engine sets the price more than anything else: a four-cylinder with the belt in easy reach sits at the bottom, a transverse V6 at the top, and many cars turn out to have a timing chain instead, which is a different and bigger job. Below are the prices by job and by car, the complaint data behind the codes a worn belt or chain sets, and how to get a fair quote.

What it costs

All prices in this article are US independent shop, parts and labor, 2026, for mainstream cars. They are writer estimates from our price book, pending sign-off by our mechanic reviewer.

Labor runs roughly $90–$180 an hour across the US; the coasts and dealer service departments sit at the top of that. Trucks, large SUVs and European cars land at or above the top of each row. If the engine is already destroyed, a used or remanufactured four-cylinder engine installed runs $4,000–$8,000.

Cost by car

The first thing to know: most of the cars that pile up engine complaints with NHTSA have a timing chain, not a belt. Before you pay for a “timing belt” job, confirm which one your engine has. The counts below are every owner complaint NHTSA has filed under its broad ENGINE category for that model year. That category covers far more than timing parts, so treat it as context, not proof of a timing problem.

The codes are the better signal for this repair. P0016 and P0017 mean the engine computer sees the camshaft out of step with the crankshaft, which is exactly what a belt that has jumped a tooth or a chain that has stretched looks like. NHTSA has 177 owner complaints on file that mention P0016 and 189 that mention P0017, and 173 and 140 manufacturer technical service bulletins name those two codes. That volume of bulletins is worth a question to the shop: ask whether one applies to your engine before they quote a full chain job.

Signs you need it

• You are at or past the interval. This is the main one. Belts rarely warn you. Look up the mileage and the time limit in your owner’s manual, and note whether your climate or towing puts you on the shorter schedule.
• Check engine light with P0016 or P0017. Cam and crank are out of sync. On a belt engine, a slipped tooth; on a chain engine, stretch or a worn guide. See P0016 and P0017.
• Cranks normally but will not start. A broken belt spins the engine with no compression pattern. If this happened while driving, do not keep cranking it. More on this in car cranks but won’t start.
• Rattle for a few seconds at cold start. A chain engine with a worn tensioner or stretched chain. The noise guide is in car rattling noise.
• Whine, chirp or ticking from the front of the engine. Usually a failing tensioner or idler pulley bearing, which is part of the belt kit. See car ticking noise.
• Coolant drip under the front of the engine. A water pump driven by the timing belt is starting to leak, and a leaking pump can soak and ruin a new belt. See car leaking coolant.

P0335 is a different case. It is a crankshaft position sensor circuit code, and the sensor ($150–$400) is the usual fix, not the belt. NHTSA has 101 complaints mentioning it; 31 of those are Nissan Altimas, which use a chain.

Can you wait?

Yes, for a short while, if you are simply near the interval. No noise, no light, engine runs fine: book the job in the next few weeks and keep driving normally. Do not stretch it by 20,000 miles. The time limit matters too; a low-mileage car that is ten years old is due.

Short trips only if a chain engine rattles for a second or two at cold start and then goes quiet, with no code. It is wearing, and the rattle tends to get longer. Get a quote this month.

No, have it towed if the belt has broken, if you have P0016 or P0017 with rough running or loss of power, or if you can see cracks, missing teeth or fraying on the belt. On an interference engine, a snapped belt lets the pistons hit open valves. That turns a $500–$1,300 job into $1,500–$4,500.

What drives the price

Engine layout. An inline four-cylinder mounted sideways, with the belt at the front of the car, is a three-hour job. A sideways V6 has the belt tucked against the fender, needs an engine mount off and sometimes the engine lowered, and runs twice as long. Longitudinal V6 and V8 truck engines mostly use chains.

Kit versus belt only. A shop that replaces only the belt and reuses a 100,000-mile tensioner and idlers saves you maybe $100 and puts the new belt at risk. Pay for the kit.

The water pump. On many belt engines the timing belt drives the pump, so reaching one means reaching the other. Doing both together adds perhaps $150–$250. Doing them separately means paying the same labor twice, which is why the pump alone on these engines costs $400–$1,200. The water pump replacement cost page has the details.

Seals and extras. Cam and crank seals, the serpentine belt and coolant often go in at the same time for a small parts cost, because the labor is already paid.

Part quality. OEM or major-brand kits are the norm here. This is not the part to buy cheapest, because failure costs an engine.

The thing that makes it expensive: waiting until it breaks on an interference engine. That is the whole reason the interval exists.

DIY or shop?

A timing belt is an advanced DIY job. You need a way to lock the cam and crank in place (engine-specific locking tools on many engines), a torque wrench, a crank pulley holder, often an engine support, and the factory procedure. On a simple four-cylinder a careful home mechanic can do it in a weekend. On a transverse V6 it is a long day for a professional.

What goes wrong: the belt goes on one tooth off, the tensioner is set wrong, or the crank bolt is not torqued to spec. Any of those can destroy the engine on the first drive. If you do it, turn the engine over by hand two full turns before you start it. DIY parts cost is about $100–$400 for a kit with a water pump.

A timing chain is a shop job for almost everyone. The front of the engine comes apart, and on some engines it comes out of the car.

How to not overpay

• Confirm belt or chain first. Your owner’s manual maintenance schedule tells you. If it lists no belt replacement, you have a chain, and a “timing belt service” quote is wrong.
• Get the estimate in writing, itemized. Belt, tensioner, idlers, water pump, seals, coolant, labor hours. Compare hours between shops; that is where quotes differ most.
• Ask what brand of kit goes in and what warranty covers the job. A year or 12,000 miles on parts and labor is common at independent shops.
• Get a second quote on anything over $1,000, and on every chain job. Ask whether a manufacturer bulletin or extended coverage applies to your engine.
• Tell the shop your mileage, the last belt service (if you have the receipt), and any codes or noises. If you have P0016 or P0017 and want to know whether a quote makes sense for your car, ask the AI mechanic.
