Mitsubishi Eclipse Cross Timing Chain Service Malaysia
The 4B40 engine uses a timing chain rather than a timing belt, which is designed to last the life of the engine under normal conditions. There is no scheduled replacement interval for the chain itself, but consistent oil changes with quality 0W-20 fully synthetic oil are critical — oil starved chains stretch prematurely and can cause engine damage. Any unusual rattling noise from the engine on cold start may indicate chain tensioner wear and should be investigated promptly.
Eclipse Cross 4B11T Timing Chain
The 4B11T uses a timing chain. Turbo engines especially benefit from short oil change intervals — do not exceed 10,000 km on 0W-20 fully synthetic. The turbo oil feed and drain lines should be inspected at 80,000 km for carbon buildup or restrictions.
