The 5.9L diesel engine accessory drive system (without a/c) consists of:

  • Generator Pulley (1)
  • Water Pump Pulley (2)
  • Idler Pulley (3)
  • Power Steering Pump Pulley (4)
  • Radiator Fan Pulley (5)
  • Crankshaft Pulley (6)
  • Automatic Tensioner (7)

The 5.9L diesel engine accessory drive system (with a/c) consists of:

  • Generator Pulley (1)
  • Water Pump Pulley (2)
  • Idler Pulley (3)
  • Power Steering Pump Pulley (4)
  • Radiator Fan Pulley (5)
  • Crankshaft Pulley (6)
  • Automatic Tensioner (7)
  • A/C Compressor Pump Pulley (8)

CAUTION: Do not attempt to check belt tension with a belt tension gauge on vehicles equipped with an automatic belt tensioner.

NOTE: The belt routing schematics are published from the latest information available at the time of publication. If anything differs between these schematics and the Belt Routing Label, use the schematics on Belt Routing Label. This label is located in the engine compartment.

Drive belts on diesel engines are equipped with a spring loaded automatic belt tensioner.
This belt tensioner will be used on all belt configurations, such as with or without air conditioning.

  1. A 1/2 inch square hole is provided in the automatic belt tensioner. Attach a 1/2 inch drive-long handle ratchet to this hole.
  2. Rotate ratchet and tensioner assembly clockwise (as viewed from front) until tension has been relieved from belt.
  3. Remove belt from water pump pulley first.
  4. Remove belt from vehicle.


CAUTION: When installing the accessory drive belt, the belt must be routed correctly. If not, engine may overheat due to water pump rotating in wrong direction. Check for correct engine belt routing. The correct belt with correct length must be used.

  1. Position drive belt over all pulleys except water pump pulley.
  2. Attach a 1/2 inch ratchet to tensioner.
  3. Rotate ratchet and belt tensioner clockwise. Place belt over water pump pulley. Let tensioner rotate back into place. Remove ratchet. Be sure belt is properly seated on all pulleys.

I got the belt off with no issues, great example! I am having a problem with the water pump though. I have taken out two mounting bolts one at the 1 O'clock position and the other from the 7 O'clock position. I cannot see any more bolts. Is there another bolth that I cannot see or there is some special way for the pump to release?
Sometimes this is a little difficult, to get the water pump remove. Does your water pump have threaded holes in the water pump itself? Some of them did which you placed new bolts and anyone actually push the water pump out of the block
