7. Remove the pump pulley.
8. Turn away bolts and remove pulleys from a sock of a crankshaft.
9. Remove the covers, loosen the tensioner and, without violating the installation of the crankshaft, remove the toothed belt, marking the direction of rotation on it with a small one.
10. Disconnect a hose, turn away bolts and remove the pump.
11. Check the condition of the pump. If there is damage to the housing or leakage through the inspection hole, replace the pump (beyond repair). Clean the split plane of the pump.
Installation
Installation is carried out in the reverse order, taking into account the following:
- replace the pump gasket and o-ring by wetting it with water or liquid (not buttered);
- tighten the pump mounting bolts in 2 stages: bolts with marking "4"
- with a torque of 14 Nm, bolts with marking "7" - 24 Nm;
- put on the toothed belt so that there is no slack between the crankshaft and oil pump sprockets, or the oil pump and camshaft sprockets. Loosen the tensioner bolt and rotate the crankshaft so that the camshaft sprocket is 2 teeth away from the alignment mark. If the belt on the camshaft becomes loose, then take up the slack by slightly shifting the tensioner down. Tighten the lower, then the upper tensioner bolts;
- tighten the bolts of the belt covers with a torque of 11 Nm, the crankshaft bolt - 120 Nm, the small pulley bolt - 25 Nm, the pulley and impeller nuts on the cooling pump - 11 Nm.
When finished, warm up the engine, restore the fluid level and adjust the belts.
