→ Fig. 1    Resistance values for coolant temperature sender (G62)

The diagram is divided into two temperature ranges:

  •     A -    From 0...50 °C
  •     B -    From 50...105 °C

Examples:

  • ◆ 30 °C is in range A and corresponds to a resistance of 1.5...2.0 kω
  • ◆ 80 °C is in range B and corresponds to a resistance of 275...375 ω

The diagram is divided into two temperature ranges:

  •     A -    From 0...50 °C
  •     B -    From 50...105 °C

Examples:

  • ◆ 20 °C is in range A and corresponds to a resistance of 2.3...2.6 kω

→ Fig. 3    Removing and installing air cleaner

Removing

  • ‒ Pull crankcase breather hose -4- off air cleaner housing.
  • ‒ Unclip ignition cables -5- out of air cleaner upper part.
  • ‒ Remove air cleaner.

Installing

  • ‒ Installing the air cleaner is carried out in the reverse order.

Note:

To secure the air cleaner lower part to the air cleaner upper part self tapping screws are used. If these screws are loosened or tightened with a power tool the thread in the air cleaner upper or lower parts can be damaged.

For this reason the use of a power tool can only be used when:

  • ◆ The power tool maximum speed is 200 rpm.
  • ◆ The tightening torque is set to a maximum of 3 Nm.
