F2B ENGINE 109 T RAKKER E URO 4/5 PRINT603.93. 641 Print 603.93.641 Base q November 2006 543210 Electromagnetic fan drive Figure 216 78842 ELECTROMAGNETIC FAN DRIVE SECTION The electro-magnetic fan drive action depends on: - the coolant temperature; - the climate control system fluid pressure (if any); - the slowing down action of the intarder on (if any). Coolant temperature for: - engagement 93 C - disengagement 88 C With climate control system Climate control system fluid pressure: - 2nd speed engagement 22 bar With intarder With braking power below 41% of maximum power. Coolant temperature for:
- 2nd speed engagement 93 C - disengagement 88 C With braking power over 41% of maximum power: Coolant temperature for: - 2nd speed engagement 85 C - disengagement 80 C Using a feeler gauge, check the gap between the anchor assembly (2) and the pulley (1), it must be no greater than 2.5 mm. As to the description of the electro-magnetic joint operation and servicing, see the Volume 3.
