- Loosen the tensioner to slacken the old belt. Do not remove the bolts completely.
- Carefully slip the old belt off the alternator, crankshaft, and any other pulleys. Note the routing path.
- Inspect all pulleys for wobble, grit, or damage. Clean them before installing the new belt.
- Route the new belt following the correct path. Ensure all V-grooves are properly seated.
- Apply tension to the belt according to your engine's service manual specifications (typically about half an inch of deflection).
- Tighten the tensioner and alternator mounting bolts securely.
- Reconnect the battery terminal, start the engine, and listen for abnormal noises while checking for proper belt alignment.

This belt fits specific Volvo Penta 3.0L engines from 1994–1998 and various OMC 3.0L models. The most reliable method is to match the OEM part number 3853536 from your old belt or service manual. Additionally, check your exact engine model against our compatibility table.
What are signs my alternator belt is failing?
