• Drain coolant ⇒ 1.3 Draining and adding coolant.

• Unscrew bolts -2-.
• Remove cover for thermostat housing -1-.

• Unclip wiring harness -3- and place to one side.
• Unscrew bolts -1-.
• Place a cloth underneath to catch any oil which may drain out.
• Take off cap -5-.
• Pull off pipe -2-.
• Remove toothed belt cover -4-.
• Preassemble test tool - VAS 611 007- ⇒ 2.4.1 Preassembling test tool VAS 611 007 without ACT.
• Install test tool - VAS 611 007- ⇒ 2.4.3 Mounting test tool VAS 611 007 without ACT.

• Make sure that brakes -a- are released on both sides.

• Make sure that brake indicator on display is green -A-.

• It must not be yellow or red.

• Unscrew locking pin - T10340- -A-.
• Turn crankshaft 2 turns in direction of rotation of engine.
