Engine Timing Belt Guide for the 2017-2023 Honda Pilot
Everything you need to know about replacing the timing belt on your Pilot's V6 engine.
- The V6 in your Pilot is an interference engine; a broken timing belt will cause catastrophic engine damage.
- Replace the complete timing belt kit (belt, tensioner, idlers, water pump) every 7 years or around 105,000 miles.
- Use a high-quality kit from an OEM supplier like Aisin or a trusted aftermarket brand like Gates or Continental.
- This is not a DIY job for beginners; it requires special tools and expertise to avoid engine damage.
Understanding Your Pilot's Timing Belt
The V6 engine in your 2017-2023 Honda Pilot is an "interference" engine. This is a critical detail. It means that if the timing belt were to break, the pistons would crash into the engine valves. This event causes catastrophic and very expensive engine damage. Because of this, replacing the timing belt at the recommended interval is not just a suggestion—it's essential preventative maintenance to protect your engine.
When to Replace Your Timing Belt
The recommended replacement schedule for the Honda Pilot is typically every 7 years or around 100,000 to 105,000 miles, whichever comes first. The vehicle's Maintenance Minder system will display a code (sub-code 4) when it's time for this service. Waiting longer than this is a major risk.
Known Issues, Recalls, and Service Bulletins
While the J35 engine is generally reliable, there have been some specific issues related to the timing belt for this generation of Pilot:
- Recall for 2018-2019 Models: Honda issued a recall for some 2018-2019 Pilots because the timing belt teeth could separate from the belt. This could cause the engine to stall, increasing the risk of a crash. Dealers were instructed to inspect the timing belt and replace it for free if it was from the faulty batch.
- TSB for Chirping Noise: Technical Service Bulletin (TSB) 16-054 was released for 2016-2019 Pilots that developed a chirping noise from the timing belt area after the engine warmed up. The cause was the timing belt contacting the crankshaft pulley, and the fix involves installing a special shim.
Choosing the Right Aftermarket Timing Belt
When you replace your timing belt, you should always replace the full kit, not just the belt itself. A complete kit includes the belt, the hydraulic tensioner, idler pulleys, and the water pump. The water pump is replaced at the same time because it is located behind the timing belt and requires the same significant labor to access.
The quality of the hydraulic tensioner is just as important as the belt itself. A failed tensioner can cause a brand new belt to fail, leading to the same engine damage you're trying to prevent.
Here's a breakdown of trusted aftermarket brands:
- OEM-Level Quality (Mitsuboshi, Bando): Honda does not manufacture its own belts. The original belts are often made by companies like Mitsuboshi or Bando. Choosing a kit from a brand like Aisin is a popular choice because they often bundle these OEM-supplier parts (like a Mitsuboshi belt and Koyo bearings) and are considered equivalent to buying parts from the dealer.
- Top-Tier Aftermarket (Gates, Continental): Gates and Continental are highly respected brands in the aftermarket world. They produce high-quality belts and components that meet or exceed OEM specifications. Many professional mechanics trust and use Gates kits for this repair.
- Standard Aftermarket (Dayco): Dayco is another major manufacturer that also supplies some OEM parts. Their quality is generally considered good and comparable to other major brands, offering a reliable and cost-effective option.
Pro Tip: Avoid Counterfeits
Because these parts are so critical, it's important to buy from a reputable auto parts supplier. Avoid purchasing timing belt kits from online marketplaces like eBay or Amazon where counterfeit parts are common. A fake part can lead to catastrophic engine failure.
Frequently Asked Questions
What is an interference engine?
An interference engine is one where the valves and pistons occupy the same space in the cylinder at different times. The timing belt ensures they never do this at the same time. If the belt breaks, the pistons will hit the valves, causing severe engine damage. The Honda Pilot's V6 is an interference engine.
Can I just replace the belt and not the other parts?
This is strongly discouraged. The labor involved is the biggest part of the job's cost. The water pump, tensioner, and idler pulleys have a similar service life to the belt. If one of those old parts fails after you've only replaced the belt, it could destroy your new belt and your engine, forcing you to pay for the same expensive labor all over again.
Is this a DIY job?
For most home mechanics, no. This is a complex and precise job that requires special tools, like a crankshaft holding tool, and a significant amount of engine disassembly. Mistakes during installation can lead to immediate and catastrophic engine damage. This job is best left to an experienced professional.
What are the signs of a bad timing belt?
Often, there are no warnings before a belt breaks. However, you might hear a ticking or chirping noise from the engine. Other symptoms of a failing or slipped belt include a rough idle, engine misfires, difficulty starting, or a check engine light. If you suspect any issue, have it inspected immediately.
