Removal
1. Disconnect the battery from ground.
2. Drain the liquid.
3. Disconnect the upper radiator hose from the engine.
4. Mark and disconnect all hoses from the cylinder head cover.
5. Disconnect the wire from the temperature sensor.
6. Disconnect the pipes and hoses from the turbocharger, immediately plug all openings.
7. Disconnect the fuel pipes.
8. Disconnect the spark plug connectors.
9. Remove both manifolds.
10. Remove the upper belt cover. Set the piston of the 1st cylinder to TDC of the compression stroke.
11. Mark the direction of rotation on the toothed belts. Loosen the crankshaft bolt and remove the pulley without allowing the crankshaft to rotate.
12. Remove the lower belt cover.
13. Loosen the tensioner bolt, move the tensioner toward the cooling pump and tighten the bolts.
14. Remove the camshaft and fuel pump sprockets. Rotation of the shafts during removal is not permitted.
15. Remove the timing belt and fuel pump.
16. Remove the cylinder head cover and gasket.
17. Loosen the cylinder head bolts in the specified order in 2-3 steps and unscrew.
18. Remove the cylinder head and gasket.
19. Clean the removed head. Perform the necessary work.
Installation
1. Installation is carried out in reverse order. Place a new gasket and install the head.
2. Tighten the bolts in the order shown, first by hand, then in 2 stages – first to 54 N·m, then tighten to 108 N·m. Tighten the crankshaft bolt to 70 N·m.
3. When installing the belt, first tighten the tensioner bolt in the adjustment groove, and then the axle bolt. Rotation of the crankshaft when installing the belt is not allowed. Turn the crankshaft clockwise so that the camshaft sprocket moves 2 teeth from the timing mark, and then back, aligning the marks.
Check the belt tension, which should be 4-5 mm in the middle between the fuel pump and the camshaft. After finishing, check the ignition timing.
