Engine cover — removal and installation

1. During the operation of the car, especially in areas with high dust content in the air and in the autumn-winter period, all units located in the engine compartment are subject to increased pollution. Before performing maintenance work, it is imperative to clean the joints of mating surfaces, connectors of pipelines and electrical wiring before disconnecting them.

2. On top of the engine are various elements and pipelines of its systems. Depending on the type and configuration of the engine, this can be a fuel distribution line, high-pressure pipes of the power system, an ignition module, various types of supply hoses, cable lines, etc., which is especially typical for diesel engines. These elements form a complex configuration and do not allow a high-quality cleaning of the engine surface from dust and dirt, although these systems are the most sensitive to contamination. Contrary to the misconception of many, the cover not only gives the engine a more presentable appearance, but also serves to reduce the degree of contamination and prevent accidental damage to pipelines. Almost all diesel and some gasoline engines are equipped with a top protective and decorative cover - do not forget to install it in its original place after completion of work

3. The engine cover is mounted on spherical bearings fixed on various elements of the engine assembly (see illustration). The tight fit is ensured by rubber seals.

4. To remove the cover, simply pull it up with sufficient force - the rubber seals must remain on the cover, otherwise remove them manually and install them in the corresponding slots in the cover.

5. To install, align the mounting sockets with the rubber seals of the top cover with ball-shaped tips and press the cover until it is fixed on the supports - the cover should fit snugly against the mating surfaces.
