QUINTON HAZELL manufactures this Vribbed Belt Tensioner Pulley QUINTON HAZELL OE Ref to original equipment tolerances, which is why it's specified as a direct replacement for OEM 500393575 rather than a rough equivalent.
You'll find it referenced as QTA1254, EAN: 5050438163483 — worth noting down if you're getting a second opinion from a mechanic before fitting.
It's built for selected FIAT vehicles. The safest way to confirm is matching OEM reference 500393575 against your existing part, or using our vehicle lookup tool with your registration.
