Timing System & Drive Belts – Honda Accord VII (2003–2008)

The Honda Accord VII (2003–2008, chassis CL/CN) is known for its durable engines and solid long-term reliability. However, proper condition of the timing system and accessory drive belts is essential for maintaining smooth engine operation. This category includes all components for the timing system and drive belts for all major engine variants used in the Accord VII:

• petrol 2.0 i-VTEC (K20A6, K20Z2),
• petrol 2.4 i-VTEC (K24A3),
• diesel 2.2 i-CTDi (N22A1 / N22A2) – featuring an additional oil pump chain.

In this category you will find timing chains, hydraulic tensioners, guides, rails, serpentine belts, belt tensioners, idler pulleys and water pumps from trusted manufacturers: Honda OEM, Bando, Gates, INA, Aisin, NPW, GMB.

Timing Chains, Tensioners and Guides

All major engines used in the Accord VII are equipped with a timing chain rather than a belt. This includes petrol units K20A6, K20Z2, K24A3 and the diesel engines N22A1 / N22A2. The diesel variants feature a second chain driving the oil pump.

Available components include:

• timing chains for K20A6, K20Z2, K24A3, N22A1/N22A2,
• hydraulic timing chain tensioners,
• chain guides and rails with OEM-level durability,
• complete timing chain kits for 2.2 i-CTDi (main chain + oil pump chain + tensioners + guides).

Typical issues in the 2.2 i-CTDi engine include timing chain stretch and worn tensioners, often noticeable as metallic rattling or tapping around the timing case or oil pan, especially when warm. In petrol engines (K20A6, K20Z2, K24A3), the chain is long-lasting, but poor oil quality or extended service intervals may lead to noise, slack or camshaft synchronization errors.

We offer original Honda OEM parts as well as premium chains, guides and tensioners from Gates, INA, Aisin, GMB.

Serpentine Belts & Accessory Tensioners

Beyond the timing chain system, the accessory drive belt plays an important role in powering the alternator, A/C compressor and power steering pump. In this category, you will find:

• serpentine belts from Honda OEM and Bando,
• idler pulleys and tensioners from Gates, INA, GMB,
• complete belt + tensioner service kits for all engines.

A worn accessory belt may cause squeaking, vibrations or charging issues. Replacing the belt, tensioner and idler pulley as a kit ensures maximum reliability and prevents belt failure during driving.

Water Pumps for Honda Accord VII

The cooling system in the Accord VII relies on a high-quality water pump to maintain stable engine temperature. We offer:

• Honda OEM water pumps,
• premium pumps from Aisin, NPW, GMB.

If the pump becomes noisy, begins to leak or causes overheating, it should be replaced — ideally together with the accessory belt and pulleys.

Common Issues in the Honda Accord VII Timing System

Based on workshop data and user experience, the Accord VII has several characteristic timing-related issues:

• 2.2 i-CTDi (N22A1 / N22A2): stretched timing chains (main and oil pump), rattling noise when warm, possible risk of chain jumping if the tensioner is completely worn.
• 2.0 i-VTEC (K20A6, K20Z2): durable timing chain, but sensitive to oil quality; poor maintenance may lead to noise or synchronization errors.
• 2.4 i-VTEC (K24A3): generally very reliable, though long intervals between oil changes may cause chain slack over time.

All these issues can be minimized by using high-quality engine oil, maintaining correct service intervals, and replacing the chain system as a complete kit when the first symptoms occur.

FAQ – Timing System & Belts for Honda Accord VII

Does the Accord VII use a timing belt or a timing chain?
All main engines (K20A6, K20Z2, K24A3, N22A1, N22A2) use a timing chain.

When should the timing chain be replaced?
There is no fixed interval. Replacement is recommended when symptoms appear or at high mileage (200,000–250,000 km+).

What are the signs of a worn chain in the 2.2 i-CTDi?
Warm-engine rattling, tapping noises, or synchronization errors. These symptoms often indicate chain stretch or tensioner wear.

Should I replace only the chain or the entire kit?
Always replace the complete kit: chain, tensioner, guides and, in diesel engines, the oil pump chain.

Which serpentine belts are recommended?
Honda OEM, Bando and Gates offer the best reliability. Use together with INA or GMB pulleys.

How can I ensure proper part compatibility?
Provide your VIN or engine code (K20A6, K20Z2, K24A3, N22A1, N22A2) and we will help verify exact fitment.
