All other vehicles continued –  Remove alternator → Electrical system; Rep. gr.27. –  Remove expanded plastic components or seals in area of wing edges.

–	Remove plenum chamber cover -1- in exterior area → Body - front; Rep. gr.50.

–	Place support bracket -10 - 222 A- with adapter -10 - 222 A /8- behind bonnet stay.

–  Place adapter -10 - 222 A /8- behind bend -2-.   Note Plenum chamber cover is in contact with adapters -10 - 222 A /8-. –  Hook support bracket -10-222 A- into suspension eyes.

–  Detach brackets -2- from the low pressure valve in the -direction of the arrow-.   Note Disregard item -3-. –  Undo screws -1- of the low pressure valve and remove the valve from the controller housing.

–  Disconnect connector -1-. –  Unscrew the fixing screws -3- and place the expansion tank aside without removing the coolant hoses.

–  Unscrew the nut -1- and expose the earth cable. –  Take up weight of engine and remove bolts -arrows-. –  Remove coolant pump belt pulley → Chapter. –  Remove sump → Chapter.

–  Loosen pulley securing bolt. Hold belt pulley with counterhold -3415- and -3415/1-.

–  Undo socket bolts of valve timing housing. –  Undo the marked socket bolts -arrows-. –  Remove distribution chain.   Note Crankshaft bearing bush remains in sealing flange. Installation Installation is in the reverse sequence of removal. Note the following:   Note The pulley contact surfaces, securing bolt, bearing bush and crankshaft chain sprocket must be free of oil and grease. –  Clean sealing surfaces carefully. They must be free of oil and grease.   Note t  The valve timing housing is still sealed to the engine with a seal and also sealant D 176 501 A1. t  The sealant D 176 501 A1 is used to prevent leaks between the valve timing housing and the joints -1- and -2-. t  The sealant point must have a diameter of 10 mm and a thickness of approx. 1 mm. t  Do not apply sealant until directly before the valve timing housing is fitted.
