Land Rover Part Number: 4345659 - Timing Chain Guide - Cologne V6
4345659 is a Timing Chain Guide for the 4.0 Cologne V6. Fitted to Discovery models with the 4.0 Cologne V6 engine, this guide locates and supports the timing chain within the timing system. The component provides a hardened running surface that controls the chain path between the crankshaft and camshaft sprockets, resists lateral movement and helps dampen chain vibration to limit wear and reduce noise. It maintains chain alignment during load and rpm changes and reduces the risk of chain jump that can cause valve-timing damage; inspect the guide for visible wear, cracking or grooving and replace where deterioration is present to maintain timing system integrity.
