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
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.
