The Continental Timing Belt Kit - 135403 is a comprehensive set of products designed for servicing a car's timing belt. It includes five essential components that are necessary for maintaining the timing belt system in a vehicle. These components are carefully selected to ensure optimal performance and longevity of the timing belt.

The first component in the kit is a timing belt itself, which is a rubber belt with teeth that connects the crankshaft to the camshaft and ensures proper synchronization of the engine's valves. The kit also includes a tensioner pulley, which is responsible for keeping the timing belt taut and preventing it from slipping or skipping.

Another important component in the kit is the idler pulley, which guides the timing belt and helps maintain its proper alignment. Additionally, the kit contains a water pump, which is responsible for circulating coolant through the engine and keeping it at a safe operating temperature. Finally, the kit includes a timing belt tensioner, which maintains the correct tension on the timing belt to prevent it from becoming loose or too tight.

Overall, the Continental Timing Belt Kit - 135403 is a complete package that includes all the necessary components for a proper timing belt replacement or maintenance. It is a cost-effective and convenient solution for ensuring the smooth and reliable operation of a car's engine.
