• Spring-type clip pliers - VAS 6362-

Removing

• Carefully open filler cap -1- on coolant expansion tank -2- in -direction of arrow-.

• Clamp off coolant hoses on coolant pipe using hose clamps up to 25 mm - 3094-.
• Release hose clips -arrows- and detach coolant hoses.
• Remove intake manifold ⇒ 4.2 Removing and installing intake manifold.

• Lay intake manifold -1- on the workbench as shown.
• Push wooden block -2- under intake manifold.

• Insert a flat-blade screwdriver into the slot -arrow 1-.

• Carefully push screwdriver in direction of -arrow 2-. At the same time, raise coolant pipe -4- in direction of -arrow 3-.

• Raise coolant pipe -1- further in direction of -arrow-. Detach coolant pipe from fastener -2-.

Installing

• First push coolant pipe onto mounting -1- until it engages.
• Then push coolant pipe onto mounting -2- until it engages.
• Check that the coolant pipe has properly engaged by pulling on it.
