Preventive maintenance on air-cooled Porsche 911 (964) - replace Desbi belt, blower motor, etc.
I have an air-cooled Porsche 911 (964C2) at home, which was just serviced two months ago, but I took it back to the store to have the distributor belt, rotor, and cap replaced, and the fan and motor inside the rear blower fan replaced, as a preliminary maintenance.
