Changing of camshaft belt

Hi all

Just wana know, how many km does the belt go ? Is this true that is should be replaced every 75 000 km ? And how long does the lambda probe works whitin normal paramteres ?

Tipo 1.4ie

thanks

change cambelt and tensioner at 65 kilometers and lamba should last up to 90 kilometers. if you replace the lamba, only use genuine fiat ones. aftermarket ones are poor quality and wont last very long.
