Does a 2008 Toyota Tundra have a timing belt or chain?
The 2008 Toyota Tundra uses a timing chain, not a timing belt.
In 2008, the Tundra offered two primary engines—the 4.0-liter V6 and the 5.7-liter V8—and neither relies on a rubber timing belt. Both engines use a timing chain to synchronize the camshafts and crankshaft. Timing chains are designed for long life and typically require less frequent upkeep than belts, though they still benefit from regular oil changes and periodic inspection of tensioners and guides as part of routine service.
Engines and timing drive
The 2008 Tundra's two powertrains and their timing method are summarized here.
- 4.0-liter V6 (1GR-FE) — timing chain
- 5.7-liter V8 (i-Force) — timing chain
Both available engines in the 2008 Tundra use a chain-driven timing system, not a belt.
Maintenance and longevity of the timing chain
Key points about how timing chains wear and what owners should monitor.
- Expected life: Timing chains generally last for the life of the engine with proper maintenance; there is no regular replacement interval like that for timing belts.
- Signs of wear: Rattling or clattering sounds from the engine, especially at startup or under acceleration, misfires, or a malfunctioning check engine light can indicate chain or tensioner wear.
- Maintenance steps: If you notice noise or suspect wear, have a mechanic inspect the chain, guides, and tensioners; replace worn tensioners or guides and ensure clean, high-quality oil is used to minimize wear.
In practice, a timing-chain setup reduces the need for belts, but it still requires attention to oil quality and periodic inspection during service intervals.
Durability and maintenance considerations
Toyota's use of timing chains in trucks like the Tundra is part of a broader industry trend toward longer-lasting, chain-driven timing systems, though chains still rely on proper lubrication and maintenance to avoid wear that could affect engine timing.
Summary
The 2008 Toyota Tundra uses a timing chain in both its 4.0L V6 and 5.7L V8 engines, not a timing belt. Chains offer longevity and reduced maintenance relative to belts, but they still benefit from routine oil changes and periodic inspection of the chain-driven system's tensioners and guides.
Which tundra has a timing chain?
Timing Chain Kit - Compatible with 2007-2020 Toyota Tundra 5.7L V8.
Is 2008 a good year for a Toyota Tundra?
Despite being stranded once, this 2008 Tundra has been a dependable, hard-working truck. With regular maintenance and a few upgrades, it continues to run strong even after hundreds of thousands of kilometers.
Does a 2008 tundra have a timing belt or chain?
If your truck is in fact an 08 with a 4.0 V6, it does not have a timing belt. The 4.0 V6 and 5.7 V8 are timing chain engines. If the 4.7 V8 is the same as the previous generation (it should be), it does have a timing belt.
How much does it cost to replace a timing belt on a 2008 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).
