Does a Toyota Highlander have a timing belt or chain?
The Highlander uses a timing chain, not a timing belt.
Timing system across Highlander generations
Across its generations, Toyota has relied on timing chains for Highlander engines. Chains drive the camshafts in most four-cylinder and V6 configurations, providing long life relative to belts. This means there is no fixed mileage interval for belt replacement, but the chain's life depends on clean, well‑lubricated operation and healthy tensioners and guides.
Because the Highlander has transitioned through several engines over the years, the exact components may vary by model year, but the timing chain approach has been the standard throughout the model’s history.
What to know about maintenance and potential issues
Here are the essential points about maintaining a timing chain-equipped Highlander and what to watch for:
- The timing system in a Highlander is chain-driven rather than belt-driven.
- There is typically no scheduled replacement interval for the timing chain itself; chain life is tied to overall engine oil quality and the condition of tensioners and guides.
- Common wear points are the chain tensioners and guides rather than belt teeth, so routine oil changes and leak repairs help protect the chain.
- Symptoms of a problematic timing chain include rattling at startup or idle, excessive engine noise, misfires, or reduced performance; in severe cases, chain failure can cause major engine damage.
Mechanics often recommend inspecting or replacing tensioners and guides when major service is performed on the timing system; replacing the water pump is sometimes done concurrently because many Highlander engines share front-end timing components.
Practical guidance for owners
If you’re buying used or maintaining a Highlander, verify the exact engine variant with the VIN and consult the owner's manual for maintenance recommendations. A qualified technician can listen for chain noise and check tensioner wear during a routine service.
Summary
In short, Toyota Highlanders use timing chains rather than timing belts across most generations. Chains typically require less frequent maintenance than belts, provided you follow regular oil changes and address front-end wear components as needed. Confirm your specific engine configuration for accurate maintenance guidance, and consult a dealer or trusted mechanic if you hear unusual noises or suspect timing issues.
Does a 2017 Toyota Highlander have a timing belt or timing chain?
The 2017 Toyota Highlander uses a timing chain, not a timing belt. Unlike a timing belt, a timing chain is designed to last the life of the engine and does not require regular replacement like a belt does.
- Timing chain: The 2017 Highlander is equipped with a timing chain, which is a metal chain similar to a bicycle chain.
- Longevity: Timing chains are significantly more durable and are intended to last the life of the vehicle, so they do not have a scheduled replacement interval.
- Maintenance: While not a maintenance item like a belt, a timing chain can still wear out, and you should be on the lookout for symptoms like rattling or knocking noises.
Does a 2019 Toyota Highlander have a timing belt or chain?
A 2019 Toyota Highlander has a timing chain, not a timing belt. Timing chains are made of metal and are designed to last the lifetime of the engine, unlike timing belts which require periodic replacement.
- Timing chain: The 2019 Highlander is equipped with a timing chain, which is a more durable component than a belt.
- Durability: A timing chain is a metal chain and is built to last for the life of the vehicle, though it is dependent on the engine's oil being clean and at the correct pressure.
- Maintenance: Proper and regular oil changes are crucial for the longevity of the timing chain.
Does the Toyota Highlander have a timing belt?
Newer models use timing belts made of polyurethane and Kevlar for long life and durability. They can go as long as 100,000 miles although it's always a good idea to change it before then.
