General information about settings and adjustments (Opel Corsa C)

The term "settings" in this Manual does not mean a separate procedure for adjusting any of the parameters of the vehicle's systems, but a whole range of adjustments that allow you to achieve maximum engine efficiency.

If the owner of a new car has strictly adhered to the schedule of routine maintenance procedures since the day of its purchase (see Section 1), performed critical parameter checks quite often, maintained the required level of lubricating fluids, the engine will extremely rarely require additional maintenance and repairs (in addition to the replacement of components and consumables subject to increased wear).

On the other hand, if regular maintenance procedures are performed carelessly and the established inspection schedules are frequently violated, the engine's efficiency will sooner or later inevitably decrease. The likelihood of such a situation occurring is especially high when purchasing a used car. In such cases, it becomes necessary to perform a set of powertrain adjustments beyond the scope of work on the car's current maintenance.

If you purchased a car from another owner or, due to circumstances, have not carried out scheduled maintenance for a long time, the authors of this Guide recommend that you contact the nearest service station to check and adjust all engine systems, and then carry out maintenance of the car on a regular basis.

Engine tuning is a very important and responsible procedure. When doing it, do not skimp - try to conduct a full diagnosis of all systems and mechanisms of the power plant with the obligatory participation of specialists. Tuning will allow you to prevent engine failure in the future and reduce costs for fuels and lubricants and routine repairs. Below is a list of the main tuning procedures that allow you to achieve maximum efficiency from an engine in good mechanical condition.

List of basic checks and adjustments:

a) Checking the 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) Checking the fuel system (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) Checking the condition of all engine compartment hoses (see Section 9);
i) Checking and adjusting the tension of drive belts (see Section 7 and Chapter 2);
j) Cleaning, inspection and checking the battery charge (see Section 11);
k) Checking the charging system (see Chapter 5);
l) Checking the ignition/pre-glow 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).
