–  Detach vent hose -2- leading to exhaust gas recirculation valve -N18-. –  Remove hose -4- for oil pan ventilation from air pipe. –  Remove air pipe from clamps -1- and -3-.

–  Unscrew bolts -arrows-.for coolant expansion reservoir. –  Disconnect connector for insufficient coolant indicator switch -F66- at bottom of coolant expansion reservoir and place to side with coolant hoses -1- and -2- connected.

–  Separate pipe -1- from hose on oil pan. –  Separate vacuum line -2- to power brake servo-unit on firewall.

–  Unscrew bolts -Arrows- for throttle valve control unit -J338- from intake manifold.   Note Shown in illustration with engine removed.
