⚙️ 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
