## ⚙️ Key Features

-   2 x 1225 mm — a paired belt length
-   Fits 33 applications across AQ, TD, TWD, BB, TID and B engines
-   0.195 kg
-   Supersedes 966798

## 🔌 Function

Carries drive from the crankshaft pulley to an engine-driven accessory as a pair of belts sharing the load.

## ⚠️ Common Signs of Failure

-   Squealing from the front of the engine on start-up or under load
-   One belt visibly slacker or running deeper in its groove than the other
-   Cracks across the back of a belt, or glazed and shiny flanks
-   Black belt dust building up under the pulleys
-   Charge warning light flickering, or the alternator falling behind

## 🛠️ Service Notes

-   Renew both belts together — a new belt run against a worn one takes almost all the load and will not last
-   Belt 978552 is published just 1 g away at 0.194 kg with no length given, so the two cannot be separated by weight — order by number
