How much does it cost to replace a timing belt on a 2002 Toyota Highlander?

The typical cost ranges from about $600 to $1,000 at an independent shop, with dealer quotes often higher—roughly $800 to $1,300. Prices vary depending on whether your Highlander has the 2.4L 2AZ-FE four-cylinder or the 3.0L 1MZ-FE V6, and whether the water pump and other components are included in the service.

The 2002 Highlander could be equipped with either a 2.4-liter 2AZ-FE engine or a 3.0-liter 1MZ-FE engine. Both use a timing belt that generally should be replaced around 90,000 miles, though exact intervals can vary by maintenance history. Cost drivers include engine type, regional labor rates, and whether the service covers only the belt or also the water pump, tensioners, idlers, thermostat, coolant, and related components. Including the water pump and full kit typically raises the price but can reduce the risk of future failures and additional labor.

What affects the cost

The price you see is shaped by several factors. Here is a breakdown of the main elements that determine your final quote:

• Engine variant (2AZ-FE 2.4L vs 1MZ-FE 3.0L V6)


• Whether the water pump is included in the service


• Labor rates by region and shop type (dealer vs independent)


• Additional components replaced (thermostat, seals, coolant, timing belt kit)


• Warranty and service plan considerations

Because these factors vary, quotes can differ widely. Always confirm exactly which parts and services are included in the price.

Typical price ranges

Below are broad ranges you might expect for a timing belt service on a 2002 Highlander. The low end usually reflects belt-only service, while the high end includes a full kit with water pump and extra components.

• 2.4L 2AZ-FE (timing belt kit only): $400–$700


• 2.4L 2AZ-FE (belt plus water pump and full kit): $700–$1,100


• 3.0L 1MZ-FE (timing belt kit only): $450–$800


• 3.0L 1MZ-FE (belt plus water pump and full kit): $900–$1,300

Note: Dealer pricing tends to be higher than independent shops. For precise estimates, obtain quotes from a few local shops with details about your engine type and which parts you want included.

DIY vs professional service

Replacing a timing belt is a mechanically complex task that requires precise timing alignment. While doing it yourself can save labor costs, mistakes can cause severe engine damage. In many cases, the time savings and risk management favor professional service, especially for the 2002 Highlander’s 2AZ-FE or 1MZ-FE engines.

• Pros of professional service: correct timing, reliable adhesion of new components, warranty coverage, no specialized tools needed by you.


• Cons of DIY: higher risk of misalignment, potential engine damage, need to acquire timing tools and parts, and longer project time.

If you’re not experienced with timing belt work, it’s generally advisable to choose a reputable shop.

How to get an exact quote

To obtain precise pricing for your 2002 Highlander, contact local shops with your engine information (2AZ-FE or 1MZ-FE), current mileage, and whether you want the water pump and full kit included. Ask for a written estimate that lists parts and labor separately, and confirm whether a coolant flush, thermostat replacement, or seals are included.)

Summary

Replacing the timing belt on a 2002 Toyota Highlander typically costs between $600 and $1,300, depending on engine type (2AZ-FE or 1MZ-FE) and whether you replace the water pump and related components. Get multiple quotes, verify exactly what is included in each price, and weigh the benefits of including a full kit versus belt-only service. Regular timing-belt maintenance at the recommended interval helps prevent costly engine damage and keeps your Highlander reliable.

Is it worth replacing a timing belt?

These car parts are subject to great forces inside the vehicle's engine. For this reason, every vehicle that has a timing belt will require a new timing belt replacement at some point during its life. Without a fully functioning timing belt, the car's engine won't be able to run properly.

Does a 2002 Toyota Highlander have a timing belt?

No, a 2002 Toyota Highlander V6 does not have a timing belt; it uses a timing chain. However, the 4-cylinder models from the same era may use a timing belt, so it depends on the specific engine. Timing chains are designed to last longer, but they can still wear out over time and cause issues like rattling noises or rough idling, so it's important to check the engine size and consult your owner's manual for specific maintenance information.

What to do if you have a 2002 Toyota Highlander

• Verify the engine type: Check your owner's manual or the vehicle's VIN to confirm if you have the 4-cylinder or V6 engine, as this will determine whether it uses a timing belt or chain.
• For the V6 (timing chain):
  • Listen for noises: A rattling sound on startup or rough idling can indicate a worn timing chain. 
  • Check oil levels: Regular oil changes help maintain the tensioners and guides for the timing chain. 
• For the 4-cylinder (timing belt):
  • Check for wear: Inspect the belt for cracks, fraying, or glazing. 
  • Consider replacement: It's generally recommended to replace the timing belt around 90,000 miles to prevent failure. 
  • Replace other components: It's wise to replace the water pump, tensioner, and idler pulleys at the same time to avoid future labor costs.

How much does it cost to replace a timing belt on a Toyota Highlander?

The cost for a Toyota Highlander timing belt replacement typically ranges from $1,100 to over $2,000, depending on the model year, labor rates, and whether the water pump and other parts are replaced at the same time. Expect to pay around $1,141-$1,269 at a dealership and potentially $743-$839 at an independent shop for the belt alone, but including parts like the water pump can add significant cost. Getting quotes from both dealerships and independent mechanics is recommended to find the best price.

Cost breakdown and factors

• Dealership vs. Independent Shop: Dealerships often charge more due to higher labor rates and the use of OEM (original equipment manufacturer) parts, but their work typically comes with a manufacturer's warranty. Independent shops are often less expensive, potentially using aftermarket parts. 
• Parts: It is highly recommended to replace the water pump and tensioners at the same time, as the labor involved is extensive and often costs more than the belt itself. This adds to the total price but prevents future costly repairs. 
• Labor: The labor is the most significant part of the cost because many components must be disassembled to access the timing belt. A simple timing belt job can be time-consuming, sometimes taking 6+ hours. 
• Model year: Older models may have different replacement costs compared to newer ones. 
• Other Services: You can often bundle other services, such as spark plug replacement, into the job to save on labor costs. 

How to estimate your cost

• Get multiple quotes: Contact both dealerships and independent mechanics to compare prices for the specific job you need (e.g., timing belt only or timing belt with water pump).
• Ask about parts: Inquire whether the quote includes the water pump, tensioners, and any seals, and if OEM or aftermarket parts will be used. 
• Check warranties: Ask about the warranty on parts and labor, especially if you choose an independent shop.
