Therefore engine tension rollers have to meet a number of demanding parameters:

 
• Minimum extension of the belt during long-term stress
• Maintenance-free operation
• Error-free operation through the service life

 
 
The timing belt mechanism includes tension rollers that correctly tension the timing belt. The correct setting and quality of timing belts and tension rollers are therefore vitally important for the long service life of an engine and the safe operation of a vehicle.
 
The origin of these parts should not be ignored. We recommend genuine ŠKODA parts for ŠKODA cars. We guarantee the quality of the materials used. For example, our precise production processes have enabled us to extend the interval for changing a timing belt on a Fabia with a 1.9 TDI PD/74kW engine from 90,000 km to 120,000 km.

 
ŠKODA genuine belts and pulleys are now supplied in sets which contain:
 
• A timing belt
• Tension rollers
• Guide rollers
