How many belts does a Toyota Tacoma have?

A Toyota Tacoma typically has one serpentine belt that drives accessories, and cam timing is managed by a chain rather than a separate belt.

Understanding the belt setup across Tacoma generations

In practice, Tacomas rely on a single belt to power essential components, while the timing system uses a chain. This means there is no separate timing belt to replace in standard Tacoma engines.

Key points about the belt configuration include:

• Single serpentine belt: This belt runs the alternator, power steering pump, air conditioning compressor, and water pump in most engines.


• Timing chain, not a belt: The camshafts in Tacoma engines are synchronized by a timing chain rather than a timing belt.


• No separate timing belt replacement: Since there is no timing belt, there is no periodic timing-belt service for these engines.


• Maintenance intervals vary: Serpentine belt replacement is guided by the owner's manual and depends on engine year and driving conditions; typical intervals range widely and should be confirmed in your manual.


• Watch for wear signs: Cracks, fraying, squealing noises, or loss of belt tension indicate the belt or tensioner may need replacement.

For specifics on your exact model year and engine, consult the owner's manual or a Toyota service professional.

Common questions by model year

Are there Tacomas with more than one belt?

In modern Tacomas, there is typically only one drive belt—the serpentine belt—because the timing is driven by a chain. Some older or non-standard configurations could differ, but they are not representative of mainstream Tacoma models.

To confirm for your vehicle, check the belt routing diagram under the hood or review the service manual for your exact engine and year.

Summary

Bottom line: Most Toyota Tacomas use a single serpentine belt to power accessories, with cam timing handled by a chain rather than a belt. This means a single belt is the primary belt to service, while the timing system does not require a separate belt replacement. Always verify with your vehicle’s manual for your specific engine and model year.

Do tacomas have timing belts or chains?

Most Toyota Tacomas use a timing chain, but older models (1995–2004) with a V6 engine had a timing belt. Newer Tacomas use a timing chain, which generally lasts the life of the engine unless it has issues like stretching or worn guides.

Timing chain (most models)

• Which models: The 2.7L four-cylinder and 4.0L/3.5L V6 engines from around 2005 and later use a timing chain. 
• Lifespan: It is designed to last the life of the engine and doesn't require replacement at set intervals, though it is good to have it inspected during major service intervals. 
• When to check: A stretched chain can cause a check engine light and noise from the timing cover. 

Timing belt (older V6 models) 

• Which models: V6 engines from 1995 to 2004 used a timing belt. 
• Lifespan: Timing belts need to be replaced at recommended intervals, typically between 60,000 and 100,000 miles. 
• When to check: You can check if the timing belt is old or cracked by carefully prying the upper timing belt cover, which is often accessible with the removal of a few bolts. 
• Interference engine: The V6 engine is non-interference, meaning if the timing belt breaks, the engine will not be damaged.

Does Tacoma have serpentine belts?

This is a genuine OEM serpentine belt for the 2016-2023 Toyota Tacoma 3.5L V6. It is made by Toyota and has the OE/OEM part number 90916-A2037. This accessory belt is designed for the front of the vehicle and is an essential part for the proper functioning of the engine.

Your car's belt system has two primary players: the serpentine belt that keeps components like the alternator, water pump, and air conditioning compressor running, and the timing belt that synchronizes the crankshaft and camshaft for optimal combustion timing.

How much does it cost to replace a serpentine belt on a Toyota Tacoma?

The average cost for a Toyota Tacoma serpentine belt replacement is between $100 and $350, with some estimates falling higher, especially for dealer service or if additional parts are needed. Labor costs are usually the largest portion of the price, with parts costing roughly $20-$100, depending on the specific vehicle and where you purchase them. 
Estimated costs

• Professional replacement: Expect to pay between $150 and $350 for professional replacement, with the cost varying depending on the shop, location, and your specific model and year. 
• Parts only: A new serpentine belt typically costs between $20 and $100, depending on the brand (e.g., OE parts from the dealer versus aftermarket options). 
• DIY: If you're comfortable doing the work yourself, you can save on labor costs by just paying for the part. You will need basic tools like a breaker bar or tensioner tool. 

Factors that affect cost

• Labor: This is the most significant factor. The cost will be higher at a dealership than at an independent shop. 
• Parts: OE (original equipment) parts from the dealership are often more expensive than aftermarket parts. 
• Location: Costs can vary depending on where you live; major metropolitan areas generally have higher labor rates. 
• Additional repairs: A serpentine belt replacement is often done with other parts in mind, like tensioners and idler pulleys, which would increase the total cost. 

How to get an accurate estimate

• Contact local mechanics: Get quotes from a few different local mechanics and dealerships to compare prices for your specific model and year.
• Ask about additional parts: Inquire if a tensioner or idler pulley replacement is recommended at the same time, as these parts can fail over time and it may be cost-effective to replace them proactively. 
• Provide your vehicle's year, make, model, and engine size: This will ensure you get an accurate quote.
