Related Parts and Hardware

When replacing a multi-groove belt, we strongly recommend inspecting the condition of the belt tensioner and all idler pulleys. Worn bearings in the pulleys or a weak tensioner will destroy a new belt.

⚠️ Safety Warning

A failure of the 320/08608 belt leads to an immediate stoppage of the alternator (loss of charging) and the water pump (loss of cooling). Ignoring the charging warning light and continuing to work will lead to rapid overheating and engine seizure within minutes, resulting in a very costly repair.

Part Role in the Machine and Failure Diagnostics

The 8PK2002 multi-groove belt transfers drive from the engine's crankshaft pulley to key accessories. Its main job is to simultaneously drive the alternator (which charges the battery) and the water pump (which circulates coolant). In some configurations, it may also drive the fan or A/C compressor.

  • Loud squeal or whistle from the engine, worse on startup or acceleration (belt slip).
  • Visible cracks, fraying, or missing pieces of the ribs on the belt.
  • Charging warning light (red battery icon) illuminates on the dashboard.
  • Sudden rise in engine temperature (indicates water pump is not turning).
  • Uneven running or "wobbling" of the belt (sign of a bad tensioner or pulley).

🔧 Expert Guide: Key Installation Tips

  1. Replace the Kit: Always replace the belt along with the tensioner and idler pulleys. A worn bearing in a pulley will seize and destroy the new belt.
  2. Check Pulleys: Before installing the new belt, check that the grooves on all pulleys (crank, alternator, pump) are clean and undamaged.
  3. Correct Tension: Use the correct tool to release the tension on the automatic tensioner. Ensure the belt is perfectly seated in all grooves.
  4. Check After Starting: After starting the engine, visually check that the belt is running true and not "jumping" or squealing.

Frequently Asked Questions (FAQ)

What does 8PK2002 mean?

This is the standard belt designation. 8PK means the belt has 8 grooves (or ribs). 2002 is its effective length in millimeters (2002 mm).

What is the difference between this belt (320/08608) and 320/08598?

The main difference is length. This belt (320/08608) is 2002 mm long, while 320/08598 is 1835 mm long. The different length is for a different engine accessory configuration (e.g., with or without air conditioning, or a different pump setup).

My belt squeals. Do I need to replace it?

Squealing is usually a sign of the belt slipping. This can be caused by wear (hardened rubber) or, more likely, a faulty automatic tensioner that is not providing enough pressure. Replacing only the belt without checking the tensioner will usually only solve the problem for a short time.
