Mercedes-Benz GLE — 时规链

All GLE engines — M264, M256, M176/M177 — use timing chains. No belt replacement required. Chain stretch and tensioner wear are the relevant concerns, especially on high-mileage W166 GLE with V6 engines. Correct oil spec and on-time oil changes are the best prevention.
Repair Costs
- 4-cylinder (M264) chain
- V6 (M276/M256) chain
- V8 (M176/M177) chain
- Warning: cold-start rattle in first 5 seconds = get XENTRY check immediately
