Acura ILX Timing Belt or Chain (All Years 2013-2022)

The Acura ILX is a compact luxury sedan manufactured and sold by Honda under the Acura brand for the U.S. market from the 2013 through 2022 model years. Based on the ninth-generation Civic platform, the ILX replaced the Canada-only Acura CSX and served as the brand’s entry-level sedan throughout its production run.

Timing system identification matters for any vehicle owner planning long-term maintenance. A timing belt requires scheduled replacement at fixed mileage intervals. A timing chain typically runs the life of the engine. Confusing the two can lead to skipped maintenance or unnecessary service costs.

Engine options in the ILX varied by model year. The early lineup offered a 2.0-liter four-cylinder, a 2.4-liter four-cylinder, and a 1.5-liter hybrid. Later years consolidated to a single 2.4-liter engine with direct injection. The timing system type remains consistent across every variant.

Does the Acura ILX Have a Timing Belt or Timing Chain?

All U.S.-market Acura ILX models from 2013 through 2022 use a timing chain. No ILX model year or engine variant was equipped with a timing belt. This applies to every engine offered: the 2.0L R20A, the 2.4L K24Z7, the 2.4L K24V7, and the 1.5L LEA hybrid.

2022 Acura ILX Timing Belt Or Timing Chain

The 2022 ILX uses the K24V7 2.4-liter inline-four, which was the sole engine for the final model year. The timing chain in this engine requires no scheduled replacement. Acura’s maintenance schedule does not list a timing chain service interval for any ILX model year.

2021 Acura ILX Timing Belt Or Timing Chain

Same timing system as the previous model year. The K24V7 continued unchanged through the end of ILX production. Regular oil maintenance remains the single most important factor in preserving chain and tensioner life.

2020 Acura ILX Timing Belt Or Timing Chain

Same timing system as previous model year. The timing chain design in the 2020 ILX does not appear on Acura’s scheduled maintenance checklist. Chain-related issues typically arise only when oil changes have been neglected over extended periods.

2019 Acura ILX Timing Belt Or Timing Chain

The 2019 model year received a mid-cycle refresh with updated exterior styling and a revised interior. The powertrain carried over unchanged, retaining the 2.4L K24V7 engine with its timing chain and 8-speed dual-clutch transmission.

2018 Acura ILX Timing Belt Or Timing Chain

Same timing system as previous model year. The K24V7 engine used in the 2018 ILX relies on a hydraulically tensioned timing chain. Some owners on automotive forums report occasional cold-start rattle that resolves once oil pressure builds, a characteristic shared with many Honda K-series engines.

2017 Acura ILX Timing Belt Or Timing Chain

The 2017 ILX continued with the 2.4-liter direct-injection engine and timing chain introduced the prior year. Acura specifies 0W-20 full synthetic oil for this engine. Correct oil viscosity directly affects the hydraulic timing chain tensioner’s ability to maintain proper chain tension.

2016 Acura ILX Timing Belt Or Timing Chain

The 2016 refresh introduced the K24V7 engine, which replaced the earlier K24Z7. The new engine added direct fuel injection and an 8-speed dual-clutch transmission. The timing chain design carried over from the K-series architecture. The 2.0L R20A engine was discontinued after the 2015 model year.

2015 Acura ILX Timing Belt Or Timing Chain

The 2015 model year offered two engine choices for the final time. Both the 2.0L R20A and the 2.4L K24Z7 used timing chains with no scheduled replacement interval. The hybrid variant was discontinued after 2014, leaving only gasoline engines.

2014 Acura ILX Timing Belt Or Timing Chain

Three engine options were available for 2014. All three used timing chains. The hybrid variant paired a 1.5-liter gasoline engine with Honda’s Integrated Motor Assist system. This was the final year for ILX Hybrid production.

2013 Acura ILX Timing Belt Or Timing Chain

The debut model year launched with three engine choices. All three engines used timing chains with no belt-driven camshaft timing systems. Acura’s official knowledge base confirms the ILX uses timing chains across all 2013 engine variants.

Timing Belt vs Timing Chain on the Acura ILX

A timing belt uses reinforced rubber with internal fiberglass or Kevlar cords to synchronize the crankshaft and camshaft. Belts operate quietly and cost less to manufacture. However, rubber degrades over time regardless of mileage. Most timing belts require replacement between 60,000 and 105,000 miles.

A timing chain uses metal links, similar to a bicycle chain but far more robust. Chains run inside the engine where they receive constant oil lubrication. This design allows them to last the life of the engine under normal operating conditions. The ILX uses this type of system.

The maintenance difference between the two systems is substantial. A timing belt demands proactive replacement on a fixed schedule. Skipping this service risks sudden engine failure. A timing chain does not appear on the ILX maintenance schedule. Inspections occur only if symptoms develop.

Cost also separates the two systems. A timing belt replacement on a typical four-cylinder engine costs $500 to $1,000 including labor, water pump, and tensioner. Timing chain replacement, when needed due to neglect or wear, typically costs $1,500 to $3,000. However, chain replacement is far less common.

Acura ILX Timing System Maintenance

The ILX timing chain requires no scheduled replacement under normal driving conditions. Acura’s Maintenance Minder system does not include a timing chain service interval. The chain is designed to last the full service life of the engine when proper oil maintenance is followed.

A rattling noise on cold startup is the most common symptom of timing chain wear on ILX engines. The sound typically fades as oil pressure builds and the hydraulic tensioner engages. If the rattle persists after warmup or becomes louder over time, schedule an inspection immediately.

Engine oil quality and level directly determine timing chain longevity. The chain and tensioner rely on a steady supply of clean oil for lubrication and hydraulic pressure. Running the engine low on oil or extending oil change intervals too far accelerates chain, guide, and tensioner wear.

If timing chain service becomes necessary, replacement kits include the chain, tensioner, guides, and related gaskets. Acura Genuine timing components are manufactured to factory specifications. Aftermarket kits from manufacturers like Cloyes also offer OE-quality replacements for the K24Z7, K24V7, and R20A engines.

Frequently Asked Questions

Does the Acura ILX have a timing belt or timing chain?
All Acura ILX models from 2013 to 2022 use a timing chain. No ILX variant was ever equipped with a timing belt. This applies to every engine option offered in the U.S. market.

When should an Acura ILX timing chain be replaced?
The timing chain on an Acura ILX does not have a scheduled replacement interval. It is engineered to last the service life of the engine under normal conditions. Replacement becomes necessary only if the chain stretches, the tensioner fails, or related components wear.

How much does timing chain replacement cost on an Acura ILX?
Timing chain replacement on an ILX typically costs between $1,500 and $3,000 at a dealership or independent shop. The cost varies based on labor rates and whether chain guides, tensioner, and gaskets are included in the service.

Is the Acura ILX an interference engine?
Acura does not officially publish interference status for the ILX engines. However, Honda K-series and R-series engines are widely recognized in the automotive industry as interference designs. A timing chain failure may cause valve-to-piston contact.

What are the symptoms of a failing timing chain on an Acura ILX?
A rattling or clattering noise from the engine on cold startup is the most common symptom. The check engine light may illuminate if camshaft timing deviates from specification. Metal particles in the engine oil may also indicate chain or guide wear.

Does the Acura ILX Hybrid use a timing belt or chain?
The 2013 to 2014 Acura ILX Hybrid uses a timing chain on its 1.5-liter LEA engine. The hybrid powertrain shares this timing system design with the contemporary Honda Civic Hybrid and CR-Z.

What oil does the Acura ILX use for timing chain longevity?
Acura specifies 0W-20 full synthetic oil for ILX models with the 2.4L K24V7 engine. Earlier 2.0L and 2.4L variants also use 0W-20 or 5W-30 depending on the model year. Using the correct viscosity ensures proper hydraulic timing chain tensioner operation.

Conclusion

Every U.S.-market Acura ILX from 2013 to 2022 uses a timing chain. No model year or engine variant relies on a timing belt. The timing system does not change between years or engine codes. All four engines offered throughout ILX production use chain-driven camshaft timing.

Owners benefit from the chain design because there is no scheduled timing belt replacement cost to budget for. The trade-off is that engine oil maintenance becomes critical. Neglected oil changes are the primary cause of timing chain wear and tensioner failure in these engines.

Always verify timing system details using the owner’s manual or manufacturer service information before scheduling repairs.
