It is recommended to check and, if necessary, increase the tire pressure, check and, if necessary, replenish the volume of engine oil and cooling system fluids, windshield wiper and windshield washer at least every 4-6 weeks.
Attention! When purchasing spare parts, it is recommended to have the vehicle's technical passport with you, because often, to identify a vehicle, you need to know its body number, model range or year of manufacture. To be absolutely sure that the part you purchase is absolutely identical to the previous one, it is recommended, if possible, to take the old part with you to compare it with the one you are purchasing.
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 the oil, change the oil filter.
Cooling and heating system. Check the fluid level, antifreeze concentration. Perform a visual inspection for leaks and damage to the radiator.
Diesel Engine Cars. Replace the fuel filter.
Air filter. Replace the replaceable filter element and clean the air filter housing.
V-belt. Check the condition and replace if damage or signs of wear are found.
Caution: For vehicles without an automatic belt tensioner roller, check its tension.
Exhaust system. Inspect and ensure there is no damage, leaks or loose threaded connections.
Replace the spark plugs.
Cars with a 1.4-/1.6-liter BCA/BGU/BSE/BSF petrol engine with a power of 55/75 hp Visually inspect the timing belt and replace if necessary (in the workshop).
Diesel Engine Cars. Replace the timing belt and timing belt tension roller (in the workshop).
Cars with gasoline engines 2.0 liter (T) FSI, AXW/BLR/BLX/BLY/AXX with 110/147 hp. Replace the timing belt (in the workshop).
Perform a CO content check and print out the codes of faults registered by the self-diagnosis system (in the workshop).
Visual inspection of tightness and oil leaks
No special tools or devices are required.
1. Remove the upper engine protective cover.
2. Remove the mudguard (lower protection) engine, see the relevant chapter.
3. Inspect the pipes, hoses and their connections of the fuel system, cooling and heating systems, brake system and make sure there are no leaks, worn areas, porosity, hardening and fragility of the hoses.
Finding Engine Oil Leaks
If the engine is contaminated with oil, or if oil consumption is high, determine where it is leaking.
To do this, you should inspect the following places:
4. Open the oil filler cap and check the gasket for porosity and damage.
5. Check the crankcase ventilation hose, especially the section between the cylinder head cover and the air filter.
6. Check the cylinder head cover gasket.
7. Check the cylinder head gasket.
8. Check the sealing ring of 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 camshaft and crankshaft oil seals.
Since a leak typically causes oil to spread over a large surface area of the engine, it can be difficult to determine the location of the leak at first 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 it off with water at the car wash.
13. Sprinkle the outside of the connecting joints and their gaskets with lime or talc.
14. Check the oil level and top up if necessary.
15. Take a test drive. Since the oil liquefies when the engine is hot and therefore leaks faster, it is best to take this drive on a highway, covering a distance of about 30 km.
16. Inspect the engine after the test drive, illuminating the inspected areas with a flashlight, and identify the oil leaks. Eliminate any faults found.
Visual inspection of the cooling system for leaks
[The original can be found at: VWMANUAL]
17. Check the condition of the hoses by squeezing and bending them and make sure there are no porosity. Replace any hardened or swollen hoses.
The coolant circulation hoses must not fit too shallowly on the connecting fittings.
18. Check the strength of the hose clamps. Replace the clamps with new ones if necessary.
19. Check the condition of the coolant expansion tank cap sealing gasket and ensure that it is not damaged.
Caution! Too low a coolant level may be caused by incorrectly screwing on the expansion tank cap.
Significant losses of coolant and (or) the presence of oil in it, as well as a white exhaust gas outlet when the engine is hot, indicate a defect in the cylinder head gasket.
Attention! It is sometimes difficult to find the leak location. In this case, you should contact a workshop, which has a special device for this purpose, with the help of which the system is tested under pressure. At the same time, the mentioned device can also be used to check the safety valve of the expansion tank cap.
20. Reinstall the upper engine cover.
21. Reinstall the engine splash guard, see the relevant chapter.
