Procedure Installation is carried out in the reverse order; note the following: l  Engine installed on engine support -T10416-.   Note t  Renew the bolts tightened with specified tightening angle. t  Renew self-locking nuts and bolts as well as seals, gaskets and O-rings. t  Hose connections and air pipes and hoses must be free of oil and grease before assembly. t  Secure all hose connections with the correct type of hose clips (same as original equipment) → Electronic parts catalogue. t  Fit all cable ties in the original positions when installing.

–  Ensure that intermediate plate is engaged on sealing flange -arrow A- and pushed onto dowel sleeves -arrows B-.

–  If not already fitted, install dowel sleeves -A- for centring engine and gearbox in cylinder block. –  Install needle bearing if not fitted in crankshaft → Chapter. –  Install flywheel → Chapter. –  Secure gearbox to engine. –  Install starter → Electrical system; Rep. gr.27. –  Guide engine/gearbox assembly into body.

–  Initially hand-tighten bolts -arrows- for support arm of engine mounting as far as stop.

–  Initially screw in bolts -arrows- for gearbox mounting by hand until they make contact.   Note The bolts are tightened to final torque only after adjusting the assembly mountings → Chapter. –  Detach engine support -T10416- from engine. –  Install drive shafts and swivel joint → Rep. gr.40. –  Install pendulum support → Rep. gr.34. –  Install alternator → Electrical system; Rep. gr.27. –  Install air conditioner compressor → Rep. gr.87. –  Install poly V-belt → Chapter. –  Install catalytic converter with centre silencer → Chapter. –  Install coolant pipe → Chapter. –  Install engine control unit → Rep. gr.24. –  Install electronics box → Rep. gr.97. –  Install selector lever cable → Rep. gr.34. –  Install radiator cowl → Chapter. –  Install support arm of engine mounting → Chapter. –  Electrical connections and routing → Current flow diagrams, Electrical fault finding and Fitting locations. –  Observe notes on procedure for connecting the battery → Electrical system; Rep. gr.27. –  Install air cleaner housing → Rep. gr.24. –  Install wheel housing liners → Rep. gr.66. –  Check oil level → Booklet819.   Caution Risk of irreparable damage to control units because of excessive voltage. Never use battery charging equipment for boost starting. –  Fill up with coolant → Anchor.   Note t  Drained-off coolant may only be used again if the original cylinder head and cylinder block are re-installed. t  Contaminated or dirty coolant must not be used again. –  Install engine cover panel → Fig.. –  Install noise insulation → Rep. gr.66.
