The timing belt is made from rubber with high tensile fibres such as Kevlar running through it and is responsible for making sure that all the moving parts of an engine are perfectly synchronised.
Turning at thousands of revolutons per minute and performing under extreme mechanical stresses in intense heat, it is imperative the belts and all the tensioners are replaced at the advised maintenance schedules.
Failure to replace your timing belt can result in catastrophic engine failure.
Please refer to the handbook for your specific model of Fiat as it specifies the exact mileage or age as to when the timing belt must be replaced. Alternatively, contact one of the Fiat Service Advisors at Lookers Fiat in Stockport or complete the attached Enquiry Form and they will call you.
