Auxiliary Unit Transmission
| Number | Designation | Number | Designation |
| 1 | Servo pump | 4 | Intermediate shaft |
| 2 | Guide pulley | 5 | Belt tensioner |
| 3 | Air conditioning (A/C) compressor | 6 | Coolant pump |
The auxiliary units are located at the upper edge of the cylinder block, above the transmission. They are driven by two systems, a Poly-V-belt driven system and a clutch system. These two systems are driven by the intermediate shaft transmission.
The belt system consists of a 6-ribbed Poly-V belt, an automatic belt tensioner and a guide pulley. This system drives the servo pump and AC compressor. The coolant pump is driven by the servo pump via the clutch system.
