Belt tensioner roller. Porsche 958 Cayenne / 970 Panamera / 95B.1 Macan Diesel ❭ 958903133

This tensioner helps maintain the correct tension and routing of the accessory (serpentine) drive belt, which powers multiple engine-driven components such as the alternator, air conditioning compressor, and other auxiliary systems. By applying consistent force to the belt, the tensioner reduces slack, prevents belt slip, and supports smooth belt operation under varying engine loads and temperatures.
Fits:
Porsche 958 Cayenne 3.0L DIESEL 2011 - 2018
Porsche 970 Panamera 3.0L DIESEL 2012 - 2016

Application:
Accessory drive belt tensioner assembly - installed in the front engine accessory drive system to control belt tension and alignment.
Function:
• Applies and regulates tension to the accessory drive belt
• Maintains proper belt alignment over pulleys
• Reduces belt chatter and premature wear
• Helps ensure reliable operation of belt-driven accessories
A worn or weak belt tensioner can lead to belt slip, increased noise (squeal or chirp), uneven belt wear, and reduced accessory performance. Replacing a failing tensioner restores proper tension control and helps prolong the life of the belt and pulleys - improving reliability and reducing the risk of accessory drive failures.
Replace the tensioner if you notice:
• Squealing or chirping from the belt area
• Visible belt wear or fraying
• Belt slipping under load
• Rough or noisy pulley bearing movement
• During routine accessory belt or tensioner service intervals
