The timing chain or belt keeps the crankshaft and camshaft(s) synchronized so the valves open and close at the correct moment. On many engines, a timing failure can cause serious internal damage, which makes a dependable timing repair especially important.
The Chain or Belt Is Only One Part of the System
Timing systems also rely on tensioners, guides, sprockets, and idler pulleys. These parts wear along with the chain or belt. Replacing only the chain or belt can leave worn components in service, and a worn tensioner or guide can shorten the life of the new part.
What a Timing Kit Typically Includes
- Timing chain kits: depending on the part number, may include the timing chain(s), sprockets, tensioners, guides, and related gaskets or seals.
- Timing belt kits: depending on the part number, may include the timing belt, tensioner, idler pulleys, and in some configurations a water pump and seals.
Application Accuracy Is Critical
Timing components are engine-specific, and similar engines may use different chains, sprockets, or tensioners. Always confirm the engine code and part number, and follow the manufacturer’s timing procedure and specifications during installation.
