Genuine Honda B-Series Timing Belt Tensioner Spring OEM 14516-PR4-A00

This brand new, genuine Honda timing belt tensioner spring is designed for the legendary Honda B-series engines. It is a critical component that provides the correct initial tension to the tensioner pulley during the timing belt adjustment procedure. Choosing a Genuine Honda OEM part ensures the precise spring rate required for the safety and longevity of your engine's timing system.

Most experienced mechanics recommend replacing this spring with every timing belt change. Over time, the original spring can lose its tension or develop micro-deformations, making it difficult to achieve the exact belt tension specified in the factory service manual.

The 14516-PR4-A00 spring is designed to work with genuine tensioner pulleys with the following part numbers:

• 14510-P30-003
• 14510-PR3-003

Pro Tip: We also offer the high-quality Koyo tensioner (PU285530RR1DV1). Koyo is the original equipment manufacturer for Honda, providing factory-level performance and reliability.

Why replace the tensioner spring?

• Engine Safety: Proper timing belt tension prevents the belt from skipping, protecting your engine from catastrophic failure.
• Precision: A new spring allows you to set the tension exactly as required by Honda's service guidelines.
• Vibration Control: A weakened spring can lead to excessive tensioner vibration, accelerating wear on the pulley bearings.

FAQ – Frequently Asked Questions

Does this spring fit D-series engines (e.g., D16Z6)?
No, the 14516-PR4-A00 spring is exclusively for B-series DOHC engines. D-series engines utilize a different tensioning setup.

Is it okay to stretch the spring for more tension?
Absolutely not. Any mechanical modification to the spring alters its properties and can lead to spring failure or over-tensioning the belt, which can damage the water pump and timing bearings.
