Product Description


The "compact five" engine on P1-chassis Volvos like the S40, V50, C30, and C70 uses a relay-style accessory belt drive with two similar length belts: an outer belt runs over from the engine crank pulley/harmonic balancer to the air conditioner, and then an inner belt runs up from the air conditioner to the alternator.

These belts are not the same length, and care should be taken if replacing both belts at the same time not to mix them up.

This tensioner is for the inner (A/C to alternator) belt.

Potential Product Fitment Issues

This tensioner fits models with engine serial number 4293285 and up. Prior to ordering, please either check the engine serial sticker on your lower timing belt cover or call your dealer or IPD customer support with your VIN to look it up.
