What year does the Toyota Highlander have a timing chain?
Across every model year, the Toyota Highlander uses a timing chain rather than a timing belt. There is no Highlander year that relies on a belt for the engine’s timing.
From its launch in 2001 through the current fourth generation, Toyota has kept the Highlander’s timing system chain-driven for both gas and hybrid powertrains. Timing chains are designed to last much longer than belts, with maintenance focused on related components such as tensioners, guides, and the water pump rather than periodic belt replacements. The following overview outlines how this has held true across generations.
Generational overview
First generation (2001–2007)
The earliest Highlanders offered options including a 2.4-liter four-cylinder and a 3.0-liter V6, both configured with timing chains. This set the precedent for chain-driven timing that carried into later generations.
Second generation (2008–2013)
With updates to performance and refinement, the lineup remained chain-driven for its gas engines and hybrid option, avoiding any timing-belt configuration in these models.
Third generation (2014–2019)
The redesign introduced a more capable 3.5-liter V6 and corresponding hybrid variants, all maintaining a timing chain for the engine timing system.
Fourth generation (2020–present)
The current Highlander offers a 2.4-liter turbocharged engine along with a 2.5-liter hybrid, both with timing chains. The chain-driven approach continues across all contemporary trims.
Summary
In brief, the Toyota Highlander has used a timing chain across all model years and generations to date. There is no year that uses a timing belt, and owners should focus on standard maintenance and any wear-related components tied to the chain, such as tensioners or guides, as part of routine service. For specifics, always consult your exact engine code and the owner's manual.
