Front cover (from the radiator side)
1. Disconnect the cable from the negative terminal of the battery.
2. Remove the spark plug wires and remove the wiring harness cover (see illustrations). Before removing, number the wires to avoid confusion during installation.

Installation
13. Before installing the covers, the mating surfaces of each cylinder head and valve cover must be absolutely clean. Use a suitable scraper to remove any remaining material from the old seal or gasket, then clean the mating surfaces with lacquer thinner or acetone (if there are traces of sealant or grease left on the mating surfaces when installing the cover, oil leakage may occur through these areas). The lids are made of aluminum, so be very careful not to scratch or deform the surfaces with the scraper.
14. Apply sealant to the threads of the mounting bolts and nuts. Replace the valve cover with a new gasket, then install the nuts and bolts.
15. Tighten nuts and bolts in several stages to the required torque specified in the technical data given in this chapter.
16. Complete the installation in reverse order. Don't forget to refill the coolant system if it was drained.
17. Start the engine and check for leaks at the joints between the valve cover and the cylinder head.
