If the owner of a new car from the date of purchase strictly adhered to the schedule of routine maintenance procedures (see section 1), performed checks of critical parameters quite often, maintained the required level of lubricating fluids, the engine will very rarely need to perform additional maintenance and refurbishment (beyond the replacement of wear-prone components and consumables).
On the other hand, in the case of a careless attitude to the implementation of regular maintenance procedures and frequent violations of the established deadlines for inspections, the efficiency of the engine's output will inevitably decrease sooner or later. The likelihood of such a situation is especially high in the case of purchasing a used car. In such cases, it becomes necessary to perform a set of settings for the power unit in excess of the amount of work on the current maintenance of the car.
If you purchased a car from another owner or, due to circumstances, did not carry out scheduled maintenance for a long time, the compilers of this Guide recommend that you contact the nearest service station to check and adjust all engine systems, and then service the car on a regular basis.
Performing engine tuning work is a very important and responsible procedure. When carrying out it, you should not save money - try to conduct a complete diagnosis of all systems and mechanisms of the power plant with the obligatory participation of specialists. The tuning will further prevent engine failure and reduce the cost of fuel and lubricants and current repairs. The following is a list of basic tuning procedures to get the most out of a mechanically sound engine.
List of basic checks and adjustments:
- a) Checking compression in the engine cylinders;
- b) Diagnostics of the degree of wear of the main components and mechanisms of the engine;
- c) Checking the electronic control systems of the power plant;
- d) Checking the engine lubrication system;
- e) Fuel system check (see chapter 4);
- f) Checking the cooling system (see Section 10 and Chapter 3).
- g) Checking the condition of all fluids associated with engine operation (see Section 4);
- h) Check of a condition of all hoses of an impellent compartment (see Section 9);
- i) Checking and adjusting the tension of drive belts (see Section 7 and Chapter 2);
- j) Cleaning, Inspecting and Checking Battery Charge (see Section 11);
- k) Checking the charging system (see chapter 5);
- l) Checking the ignition/preheat system (see chapter 5);
- m) Replacing spark plugs/glow plugs (see Section 22 and Chapter 5);
- n) Checking the replacement air cleaner filter (see Section 18).
