The 2017 Honda Pilot uses a timing chain, not a belt, to synchronize the camshafts with the crankshaft in its 3.5-liter V6 engine. This chain-driven setup is designed to last the life of the engine under normal maintenance conditions.
Timing chain vs timing belt: What this means for the Pilot
The Pilot’s 3.5L V6 employs a chain-driven timing system. Here are the essential facts owners should know about this arrangement.
- Type: Timing chain (not a belt).
- Engine: 3.5-liter V6 with Honda’s i-VTEC design.
- Maintenance: There is no scheduled belt-for-replacement interval; the chain is intended to last the engine’s life. Replacement is only a concern if the chain, tensioners, or guides wear or fail.
- Symptoms of wear: A rattling or metallic noise on startup or cold operation can indicate tensioner or guide wear; progressive slack in the chain is uncommon but should be checked by a mechanic if heard.
In short, the chain-driven timing system in the 2017 Pilot minimizes routine maintenance compared with belt-driven designs, provided the engine is well maintained with regular oil changes and inspections.
Why Honda uses a timing chain in this engine
Honda designed the 3.5L V6 for durability and long-term reliability. Here are the main reasons this engine uses a timing chain rather than a belt.
- Durability and longevity: A properly maintained chain can last the life of the engine, reducing the risk of a belt failure in demanding driving conditions.
- No routine belt replacement: Unlike timing belts, chains do not require a scheduled replacement interval for normal operation.
- Engine packaging and performance: A chain-driven setup fits the engine’s design and timing accuracy across temperature and load ranges.
- Maintenance emphasis: Owners should focus on regular oil changes and periodic inspections to ensure chain tensioners and guides remain in good condition.
Bottom line: Honda’s choice of a timing chain for the 2017 Pilot aligns with a goal of long-term durability and lower maintenance requirements for the typical owner's lifecycle of the vehicle.
Summary
For the 2017 Honda Pilot, the timing mechanism is a chain, not a belt. This design favors durability and reduces the need for belt-replacement maintenance, with upkeep centered on normal oil changes and component checks around the chain’s tensioners and guides. If you hear unusual engine noises or experience performance concerns, have a qualified mechanic inspect the timing system promptly.
