In the process of servicing a car, you will soon see that it is possible - and necessary - to combine many procedures due to the similarity of the actions for their implementation. For example, if the vehicle is raised off the ground to lubricate the chassis, you should simultaneously inspect the exhaust system, suspension, steering system, and fuel system while you are under the vehicle. If the wheels are removed for other work, it makes sense to check the brakes. Finally, suppose you had to borrow or rent a torque wrench. Even if you only need it to tighten the spark plugs, you can also check the tightening torques of as many critical nuts and bolts as you have time.
The first step in a car maintenance program is self-preparation. Carefully study the materials of all Sections related to the upcoming procedures, then prepare all the necessary materials, equipment and tools. If you are afraid of encountering problems when performing any specific work, consult a specialist or a person who has already carried out this work.
By properly following the suggested maintenance program, as well as checking fluid levels frequently and inspecting high wear components, a new vehicle's engine will remain in good working order and the need for additional maintenance will be minimal.
If there is a lack of regular maintenance, engine problems can occur, which is even more likely if the car is used. In such cases, additional work needs to be done.
If engine wear is suspected, check compression (contact the head Engine repair), which will give you valuable information about the performance of its main components and help determine the extent of the required repair. If, for example, a test has shown severe engine wear, the routine maintenance described in this Chapter will only be a waste of time and money, as it will not improve engine performance unless an extensive overhaul has been previously performed (contact the head Engine repair).
The following series of actions consists of the procedures most often needed to improve engine performance:
First of all:
1. Clean, inspect and test the battery (see Schedule of ongoing maintenance).
2. Check all engine related fluids (see Schedule of ongoing maintenance).
3. Check the condition and tension of the auxiliary drive belt (Chapter Checking and replacing the auxiliary drive belt).
4. Check the condition of the air filter element and replace if necessary (Chapter Replacing the air filter element).
5. Check fuel filter (Chapter Diesel Fuel Filter Replacement).
6. Check the condition of all hoses and check them for fluid leaks (Chapter Check hoses for fluid leaks).
7. Check the idle speed and the minimum stable operation speed of the diesel engine (Chapter Power systems, release).
If the above steps are not effective, follow these steps:
1. Check the charge system (Chapter Engine electrical equipment).
2. Check the ignition or preheating system of the diesel engine (Chapter 5 Engine electrical equipment.
3. Check the fuel system (Chapter Power systems, release).
