Timing chains are built to be robust and long lasting, but like all components they are subject to stresses and wear and as such may need replacement. NAPA offers a range of replacement Timing Chains that provide a highly reliable aftermarket solution to keep an engine running smoothly without slippage. 

All NAPA Timing Chains are precision-engineered and undergo specialist treatments such as carburising to ensure superior strength, durability, and thermal resistance in all weather conditions.

NAPA says there are many different signs of a failing timing chain. These include: 

• Poor Engine Performance: A worn-out chain can lead to erratic timing, causing misfires, rough idling, and reduced power.
• Difficulty Starting: A stretched chain may delay fuel ignition, making starting difficult.
• Overheating: Incorrect timing can upset the engine’s combustion process, leading to overheating.
• Noise and Vibration: A noisy engine, particularly a clicking or rattling sound, can be a telltale sign of a loose chain.
• Check Engine Light: A check engine light often illuminates when the engine control unit (ECU) detects a misfire or timing issue.

There are a few factors that can lead to timing chain damage and eventual failure:

• Chain Wear: Over time, the metal links in the chain can wear down, leading to stretching and decreased tension.
• Tensioner Failure: The timing chain tensioner is responsible for maintaining proper chain tension. Failure of this component can result in loose chain conditions.
• Poor Lubrication: Inadequate oil lubrication can accelerate chain wear and damage. This can be caused by low oil levels or the incorrect oil specification. 
• Engine Design: Some engine designs are inherently prone to timing chain issues.

Timing chains should always be replaced at the manufacturer’s recommended service interval, regardless of function. This is typically somewhere between 125,000 and 190,000 km. 

Timing chain replacement can be a complex procedure requiring specialised tools and information. For a safe and effective replacement, investing in a timing chain kit is recommended. These kits contain all essential components, including the chain, tensioner, guides, and seals, ensuring proper timing restoration, and minimising the risk of future problems.

The NAPA Timing Chains range features a mix of standard kits, kits with gear, and VVT (Variable Valve Timing) kits for a complete fit straight out of the box. NAPA offers one of the most reliable and comprehensive timing chain ranges in the aftermarket, covering over 93% of the car parc.

NAPA Timing Chain Kits offer consistent OE-quality performance and a 3-year/48,000-km warranty guarantee. A dedicated cataloguing team ensures that all NAPA products are accurately and comprehensively catalogued and cross-referenced, allowing parts to be found in a few clicks.

Technical bulletins are available to address frequently asked questions and an in-house technical team is on hand to provide support and guidance on the full NAPA range, including installation best practice, troubleshooting, and more.
