Does the 2016 Acura MDX have a timing belt or chain?

The 2016 Acura MDX uses a timing chain, not a timing belt. The chain-driven system connections the 3.5-liter V6’s camshafts and is designed to last the life of the engine, with no scheduled belt-replacement interval. However, wear can occur in tensioners or guides, so unusual noises should be checked promptly by a qualified technician.

Engine and timing system overview

The 2016 MDX is powered by a 3.5-liter i-VTEC V6 (J35-series) paired with a 9-speed automatic transmission in most trims. In this setup, a timing chain links the crankshaft to the camshafts to maintain precise valve timing. Unlike a timing belt, a chain generally does not require a routine replacement, though it depends on healthy oil pressure to keep tensioners functioning properly.

Chain-driven design details

The MDX uses a robust chain-driven timing system with hydraulic tensioners and guides to maintain proper tension throughout engine life. While not part of the regular maintenance schedule, wear or failure of tensioners, guides, or the chain can occur and may require service if performance or noise changes are observed.

Maintenance expectations and what to watch

Below are key points about maintenance and potential issues related to the timing chain system in the 2016 MDX.

• The timing chain is chain-driven, not belt-driven. There is no standard mileage-based belt replacement interval in the owner's manual.


• Oil quality and level are critical: the chain relies on engine oil to operate tensioners and guides, so regular oil changes per Acura's recommendations help longevity.


• Tensioners, guides, and sprockets can wear over time; if these wear or if the chain becomes slack, you may hear rattling or tapping noises from the front of the engine.


• Significant chain issues can lead to poor engine performance or severe damage if the chain skips or breaks; however, such failures are relatively uncommon in well-maintained vehicles.


• If you suspect wear or hear unusual noises, have a mechanic inspect the timing area. Replacement, if needed, is costly and usually performed with other maintenance items.

In normal operation with regular maintenance, the timing chain should last many miles, and a belt-like replacement is not required.

Practical guidance for owners and buyers

If you're buying a used 2016 MDX or maintaining an existing one, keep these tips in mind regarding the timing system.

• Check the vehicle's service history for regular oil changes and any notes about timing chain tensioners or related components.


• If a seller reports a rattling sound on startup or cold start, have the chain and tensioners inspected before purchase or continued ownership.


• Budget for potential tensioner or chain service only if wear is detected; this is not a routine maintenance item like a belt replacement.

Overall, the 2016 MDX's timing chain system is designed for longevity, with proper care emphasizing oil health and early attention to unusual noises.

Summary

In short, the 2016 Acura MDX uses a timing chain rather than a timing belt. The chain system is designed to last the life of the engine, provided regular oil changes and maintenance are observed. If you hear chain-related noises or suspect wear, consult a technician promptly to avoid potential engine damage.

How much does it cost to replace a timing belt on a 2016 Acura MDX?

The average cost to replace the timing belt on a 2016 Acura MDX is between $1,100 and $1,800, depending on the repair shop. A dealer is likely to be at the higher end of this range ($1,651–$1,803), while an independent shop may be closer to the lower end ($1,071–$1,193). It's recommended to get quotes from multiple mechanics to find the best price.
 
Cost breakdown and factors

• Labor is a major cost: The high labor cost is due to the extensive amount of disassembly required to access the timing belt. 
• Parts: The total price usually includes parts like the timing belt, water pump, and tensioner. 
• Location: Prices can vary depending on your geographic location, with metropolitan areas typically having higher costs. 
• Type of shop: Dealers generally charge more than independent mechanics. 

Important considerations

• Replace related components: It is common practice to replace other parts at the same time, such as the water pump and tensioner, as they are easily accessible during the timing belt replacement. 
• Timing belt vs. timing chain: The 2016 Acura MDX uses a timing belt. If your car had a timing chain, the replacement process and cost would be different. 

How to get the best price

• Get multiple quotes from different repair shops, including both dealerships and independent mechanics. 
• Be sure the quote includes a comprehensive parts list, such as the belt, water pump, and tensioner. 
• Ask if there are any discounts, like a cash-pay discount. 

What year to stay away from Acura MDX?

You should generally avoid the 2001, 2003, 2004, 2010, and 2014 Acura MDX models due to recurring issues with their transmissions and other systems. Additionally, some 2016–2020 models with the 9-speed transmission had shift issues. Years to consider for better reliability are 2007–2009 and 2017 and later. 
Years to avoid

• 2001, 2003, 2004: These years are frequently mentioned for transmission problems. 
• 2010: This year is cited for transmission issues and potential oil burning problems. 
• 2014: Cited for transmission problems and user-unfriendly infotainment systems. 
• 2016–2020: Models from this range, especially those with the 9-speed transmission, can have shifting issues. 

Years to consider

• 2007–2009: These are noted as being among the more reliable models in the second generation. 
• 2017 and later: These models are generally considered more reliable, with improved technology and performance. 
• 2022 and newer: The new generation is showing positive early reliability and has an improved 10-speed transmission. 

Does a 2016 Acura MDX have a timing chain or timing belt?

If your Acura has a V6 engine like the Acura MDX or the RLX, it's manufactured with a timing belt that needs to be replaced for maintenance.
