Does a 2002 Toyota Tundra have a timing belt?
The timing drive on a 2002 Toyota Tundra depends on the engine installed: the 3.4-liter V6 (5VZ-FE) uses a timing belt, while the optional 4.7-liter V8 (2UZ-FE) uses a timing chain.
Engine options and timing drives
In 2002, Toyota offered two main engines for the Tundra. Knowing which engine your truck has determines whether it uses a belt or a chain for the timing system.
- 3.4L V6 (5VZ-FE): timing belt. This belt-driven setup requires periodic replacement, typically around 90,000 miles, and the belt often drives the water pump as well.
- 4.7L V8 (2UZ-FE): timing chain. Chains generally last longer than belts but should still be inspected for wear and proper tension during routine service.
In short, the timing drive is engine-dependent. If you aren’t sure which engine your Tundra has, a VIN check or under-hood label can confirm the configuration and the expected maintenance path.
Maintenance implications for belt-driven engines
For the belt-driven 5VZ-FE, skipping belt replacement can lead to sudden and catastrophic engine damage if the belt fails. The following steps are commonly recommended for this era’s belt-driven engines:
- Replace the timing belt around 90,000 miles or as specified in the owner’s manual, whichever comes first.
- Replace the water pump and drive belts at the same time, since the pump is often driven by the same belt system and failure can occur soon after belt replacement.
- Inspect and, if needed, replace tensioners and idlers to prevent belt slip or breakage.
- Use OEM or high-quality equivalent parts and follow manufacturer torque specs during installation.
After completing the service, keep a record and monitor for any unusual noises, coolant leaks, or other signs of tensioner or pump issues.
How to verify your exact engine in a 2002 Tundra
To confirm whether your specific truck has a belt or a chain, check the engine code, VIN, or under-hood stamping. The two primary configurations for the 2002 Tundra are the 3.4L V6 with 5VZ-FE (belt) and the 4.7L V8 with 2UZ-FE (chain).
Where to look for engine identification
Common places to verify your engine type include the Engine Code stamp on the engine block, the VIN sticker on the door jamb or firewall, and the ownership or service records. If you’re unsure, a dealership or qualified mechanic can confirm by cross-referencing the VIN with Toyota’s specification database.
Summary
Bottom line: A 2002 Toyota Tundra can have either a timing belt or a timing chain depending on the engine. The 3.4L V6 (5VZ-FE) uses a belt that needs replacement at around 90,000 miles, while the 4.7L V8 (2UZ-FE) uses a chain that typically lasts longer but should still be checked during regular maintenance. Identifying the exact engine is essential to follow the correct timing-drive maintenance plan.

What year do tundras have a timing belt?
Timing Belts available for the following Toyota Tundra years: 09, 08, 07, 06, 05, 04, 03, 02, 01, 00, 2009, 2008, 2007, 2006, 2005, 2004, 2003, 2002, 2001, 2000. This part is also sometimes called Toyota Tundra Timing Belts.
Does the 4.7 V8 have a timing belt or chain?
timing belts
Daymon Seiber they're ALL interface engines and use timing belts, though 05-07 are VVT-I and more likely to grenade the motor if timing belt breaks but not a guarantee on any year.
How much does it cost to replace a timing belt on a 2002 Toyota Tundra?
The real cost is in the labor, because a lot of parts need to be disassembled to get to the belt. Shopping around to get a few quotes is your best bet to get the best deal, but you can expect to pay anywhere from $409 to $919 (including parts and labor).
