It is recommended at least every 4-6 weeks to check and, if necessary, increase the pressure in the tires, check and also, if necessary, replenish the volume of engine oil and liquids of the cooling system, wiper and washer.
Attention! When buying spare parts, it is recommended to have a technical passport of the car with you, because often to identify a car you need to know its body number, model range or year of manufacture. In order to be completely sure that a part will be purchased that is absolutely identical to the previous one, it is recommended, if possible, to take the old part with you in order to compare it with the purchased one.
Engine and exhaust system
In accordance with the maintenance plan, the following types of work must be performed:
Inspect the engine, components and assemblies in the engine compartment and make sure they are tight.
Engine. Change oil, change oil filter.
Cooling and heating system. Check fluid level, antifreeze concentration. Perform a visual check for leaks or damage to the radiator.
Diesel vehicles. Replace fuel filter.
Air filter. Replace the replacement filter element and clean the air filter housing.
Ribbed belt. Check condition and replace if damage or wear is found.
Attention! For vehicles without an automatic belt tensioner, check the belt tension.
Exhaust system. Inspect and make sure there are no damages, leaks or loose threaded connections.
Replace spark plugs.
Vehicles with 1.4-/1.6 liter BCA/BGU/BSE/BSF petrol engine, 55/75 hp. Visually inspect the timing belt for the camshaft drive and replace if necessary (In workshop).
Diesel vehicles. Replace toothed belt and toothed belt tensioner (In workshop).
Cars with a gasoline engine 2.0 liters (T) FSI, AXW/BLR/BLX/BLY/AXX 110/147 hp. With. Replace timing belt for camshaft drive (In workshop).
Carry out a CO content check and print out the fault codes registered by the self-diagnosis system (In workshop).
Visual inspection for leaks and oil leaks
Special tools and fixtures are not required.
1. Remove the top protective cover of the engine.
2. Remove mudguard (bottom protection) engine, see relevant chapter.
3. Inspect the pipelines, hoses and their connections of the fuel system, cooling and heating systems, brake system and make sure that there are no leaks, worn places, porosity, hardening and brittleness of the hoses.
Finding Engine Oil Leaks
If the engine is contaminated with oil, or at high oil consumption, determine where it is leaking.
To do this, inspect the following places:
4. Open the oil filler cap and check the gasket for porosity and damage.
5. Check up a hose of ventilation of a case, in particular on a piece between a cover of a head of the block of cylinders and the air filter.
6. Check the cylinder head cover gasket.
7. Check the cylinder head gasket.
8. Check the O-ring on the oil drain plug.
9. Check the oil filter gasket, which is located between the filter and the filter mounting flange.
10. Check the oil pan gasket.
11. Check the front and rear oil seals of the camshaft and crankshaft.
Since oil leaks usually spread over a large surface area of the engine, it can be difficult to determine the location of the leak at a glance.
The following search method is recommended:
12. Wash the engine. To do this, spray the engine with an aerosol cleaner and, after letting it work, rinse with water at the sink.
13. Sprinkle outside joints and their gaskets with lime or talc.
14. Check the oil level and add oil if necessary.
15. Carry out a test drive. Since the oil liquefies when the engine is hot and therefore leaks out more quickly at leaks, this trip is best done on a high-speed road, covering a distance of about 30 km.
16. Examine the engine at the end of the test drive, illuminating the inspected places with a lantern, and determine the places of oil leakage. Eliminate the identified faults.
Visual inspection of the cooling system for leaks
17. By squeezing and bending the hose, check their condition and make sure that there are no porosities. Replace hardened or swollen hoses.
The coolant circulation hoses must not sit too tight on the connecting fittings.
18. Check up firmness of fastening of hoses collars. If necessary, replace the clamps with new ones.
19. Check up a condition of a sealing lining of a cover of a broad tank of a cooling liquid and be convinced of absence of damages on it.
Attention! If the coolant level is too low, it may be caused by improper screwing of the expansion tank cap.
Perceptible loss of coolant and (or) the presence of oil in it, as well as the release of white exhaust gas when the engine is hot, indicate a defect in the cylinder head gasket.
Attention! Finding a leak is sometimes difficult. In this case, you should contact the workshop, where for this there is a special device with which the system is checked under pressure. At the same time, using the mentioned device, you can also check the safety valve of the expansion tank cap.
20. Replace the engine top cover.
21. Reinstall the engine mudguard, see relevant chapter.
