toothed pulley bolt remnyak crankshaft 200 + to tighten on 180 ?� pulley toothed belt camshaft 55
pulley-damper to the toothed belt pulley 22
V-ribbed belt tensioner to the cylinder block 55
Timing belt cover to the engine block 10
fan cowl with viscous coupling:
M6 10
M8 22
Flywheel bolts 60 + to tighten on 180 ?�
bolt friction pad for vehicles with automatic transmission 60 + to tighten on 90 ?�
the intake manifold to the cylinder head 10

fuel to the fuel line and the fuel pressure regulator 23
air duct to the intake manifold 10
the cylinder head cover to the head 10
bracket tube power-assisted steering head cover 10
guide the oil dipstick tube to the cylinder head cover 22
rear pipe cooling system on the cylinder head 10
connecting pipe to the combination valve 10
connecting pipe to cylinder head 10
Front pipe cooling system on the cylinder head:
M6 10
M8 22
power steering hose to the hydraulic pump 40
power steering hose to the cylinder head 10
camshaft bearing caps 10
