Mercedes GLC Coupe Engine Mount Malaysia — C253/C254

• Same M274 hydraulic mounts as GLC X253 — lifespan 80,000–120,000 km
• Signs: idle vibration, acceleration thump, clunk D-to-R — Malaysia replacement RM 500–900/pair

Mercedes-Benz uses hydraulic engine mounts on many models — these are more effective than rubber mounts but more expensive to replace (RM 350–700 each). Signs of worn mounts: vibration at idle (especially with A/C on), thud when shifting from P to D, engine movement visible when revving. City stop-start driving in KL accelerates mount wear — inspect at 80,000–100,000 km. Always replace in pairs. For GLC/GLE with larger displacement engines, front mount wear often presents first. Budget RM 800–1,500 for a full mount replacement (front + rear pair).
