Continental Contitech specifically designed the Contitech Elastic technology for use on the non-tensioned BMW alternators. Use of any other manufacturers belt will not ensure proper tension over prolonged periods.
Use of other brand belts can lead to
- Premature alternator bearing failure due to too tight of a belt tension.
- Belt slippage due to too loose of a belt tension.
- Temperature-stable from -30 to 80 °C
- Tropicalized - withstands high heat extremes
- Extremely long service life
- Conditionally oil-resistant
- No retensioning necessary
The Continental Contitech elastic ribbed belts are self-tensioning which cuts drive costs considerably.
