About this part
Engine mounts on your #3 HX21 secure the engine to the chassis and absorb vibrations. Worn or cracked mounts cause excessive vibration, clunking noises and can damage surrounding components.
Frequently asked questions
What should I check when buying replacement engine mounts for the Smart #3?
Match the exact engine code and transmission type of your #3 HX21, as mount shapes and stiffness vary. Check whether you need standard rubber mounts or hydraulic fluid-filled ones.
Should I replace all engine mounts at once?
If one mount has failed, the others have likely been under extra stress. Replacing all mounts at the same time ensures balanced support and avoids repeat visits.
