Fiat 500 (Petrol) Engine Mount: Specs, Fitment & Common Faults

On the classic petrol 500, a genuinely useful DIY test isolates whether the rear engine mount is responsible for a vibration.

Generation covered: this guide is for the classic petrol/hybrid 500 (2007–2024) — not the fully electric 500e (2020–present), which is a completely different car sharing no mechanical parts despite the similar styling. Check your logbook or VIN, or confirm whether your car has an engine or an electric motor, if you're unsure which one you have.

Fiat 500 (Petrol) Engine Mount: OEM Part Number

Main engine mount	OEM part, specific to engine — confirm via VIN
Transmission mount & rear torque strut	Genuinely separate part numbers to the main engine mount — sold individually, and worth inspecting together if chasing a vibration or clunk

Accuracy note: genuinely worth knowing: hydraulic (fluid-filled) mounts and simple rubber mounts are used in different positions on the same 500 (Petrol) engine, and they aren't interchangeable — check which type is fitted at each mounting point before ordering a replacement.

A Genuinely Useful DIY Diagnostic Technique Worth Knowing — Fiat 500 (Petrol) Engine Mount

If you're trying to isolate whether the rear engine mount specifically is responsible for a vibration, this is genuinely worth trying: disconnecting the rear mount and instead supporting the engine on a trolley jack, with a block of wood and a rubber mat under the sump for protection, then running the engine to see if the vibration disappears, can help confirm whether this specific mount is genuinely the cause before committing to a replacement.

A genuinely specific, real technical detail worth knowing: the mount contains a plastic component internally that can break down and deteriorate with age and heat cycling, distinct from the more commonly expected rubber perishing — a genuine reason a mount can fail even when the visible rubber portions still look reasonably sound.

It's also genuinely worth knowing that related models in Fiat's range have had confirmed technical bulletins addressing excess engine mount vibration, with documented cases of mount failure at relatively low mileage — worth asking a dealer whether a similar bulletin applies to your specific engine.

Fiat 500 (Petrol) Engine Mount: What It Does

Engine mounts secure the engine and transmission to the chassis while absorbing vibration and movement, preventing that vibration from transferring directly into the cabin. Most versions of the 500 (Petrol) use several mounts working together — typically at least one on each side of the engine plus a torque mount — and a single failed mount can throw off the whole assembly's balance.
