Common questions

When should I upgrade my timing chain?

When should I upgrade my timing chain?

The timing chain normally needs to be replaced between 80,000 and 120,000 miles unless there is a specific problem. Issues with the chain are common in higher mileage vehicles.

When do you need a timing system replacement?

Timing system replacement is typically performed due to the detection of unstable operation. In that situation, and even in preventative maintenance situations, stress is experienced by all the timing system components.

What makes a Cloyes timing system so good?

We’re proud of our 99-year heritage and commitment to being the industry’s complete timing authority. Cloyes’ engineering focuses on the complete timing system, offering the highest quality timing kits and engine components, that meet or exceed OEM performance for stock replacement applications.

Why are timing chain components not scheduled maintenance?

The timing chain components are internal engine components and require healthy oil feed for proper function, making oil maintenance very important. Timing chain systems are not scheduled maintenance items so repairing before catastrophic failure is key; therefore, it is important to be able to recognize the symptoms.

What kind of timing gear does Melling use?

Timing gears and sprockets from Melling are provided as a part of a complete timing kit program including chain and sprocket kits, as well as for the individual gear and sprocket sales. Two piece timing gear kits are also available when the engine application calls for gears only.

What should be in a timing belt replacement kit?

The components include the timing belt, water pump, seals and gaskets, pulleys, and tensioners. Also included are the instructions and a sticker for you to note the date and mileage of the replacement.

What to look for when replacing timing chain?

When replacing the timing chain, it’s important that the accessory belt, tensioner, idler pulleys, and water pump are inspected as these components wear at a similar rate. These components are inexpensive when compared to labor costs.

Timing system replacement is typically performed due to the detection of unstable operation. In that situation, and even in preventative maintenance situations, stress is experienced by all the timing system components.

Can a timing sprocket be replaced at the same time?

Yes, Cloyes recommends that all components of the timing system be replaced at the same time. Using a worn sprocket may result in the chain not meshing with the worn sprocket, which could result in poor engine performance. Cloyes offers a wide range of complete timing chain kits for majority of vehicles on the road today.
