🔌 Function

The tensioner maintains compressor-belt pressure as belt length changes with temperature and wear.

Common signs of wear or failure:

• Compressor belt squeals

• Belt flutters at idle

• Supercharger does not engage correctly

• Reduced low-speed acceleration

• Tensioner arm oscillates excessively

• Pulley bearing rumbles

• Belt runs off-centre

• Tensioner spring feels weak

• Pulley seizes or develops radial play

Recommended checks before installation:

• Rotate the pulley bearing

• Check the arm through its full travel

• Inspect spring resistance

• Check the mounting bore and stop

• Inspect the compressor pulley and belt

• Replace a cracked, glazed or oil-contaminated belt

• Confirm belt routing before starting

📦 Condition

• Genuine Volvo Penta used part

• Pre-owned rotating and spring-loaded component

• Cosmetic marks and light corrosion may be present

• Bearing and spring operation must be checked before installation

• Supplied in protective or equivalent packaging
