Full model list at the end of this description.

## ⚙️ Key Features

-   0.685 kg
-   21 applications across five engine series
-   Engine group
-   Only 2 grams separate it from intermediate lever 849052

## 🔌 Function

Provides the spring load that keeps the tensioner pressed against the belt, taking up slack as the belt stretches and warms.

## ⚠️ Common Signs of Failure

-   Belt squealing on start-up or slipping under load
-   Tensioner failing to take up slack as the belt warms
-   Spring found broken, collapsed or with a distorted end
-   Belt flapping visibly on the slack side
-   Rapid or uneven belt wear

## 🛠️ Service Notes

-   Intermediate lever 849052 weighs 0.683 kg and shares the same fitment list - the published weights cannot separate them, so order by part number
-   A tensioner spring is a wearing item; renew the belt at the same time
-   Check the arm and spindle for free movement before blaming the spring
