Withdrawal
The radiator of AUDI cars consists of two plastic tanks, light metal tubes and cooling fins. Plastic radiator tanks for vehicles with 4- and 6-cylinder petrol and diesel engines are located on the right and left sides, and for five-cylinder engines - above and below. From these tanks, the coolant circulates through tubes, which have cooling ribs to increase the cooling surface.
If there is an obvious defect in the radiator, it can be dismantled independently for delivery to the workshop.
1. Remove the engine mudguard.
2. Drain the coolant into a suitable container.
3. Disconnect all coolant circulation hoses from the radiator.
4. Disconnect the power plug of the radiator fan thermal switch.
5. Disconnect the radiator fan power plug
6. Four- and six-cylinder petrol and diesel engines. Turn out bolts of fastening from above and from below on both sides of a radiator (see illustration).
7. Give the radiator a little back and remove it together with the blower fan.
8. Five-cylinder engine. Remove the upper part of the protective radiator cap. To do this, unscrew the nuts of the fastening bolts and remove the cover by pulling it forward (see illustration).
9. Disconnect the supply and return hoses from the radiator, as well as the hose going to the expansion tank.
10. Remove the holder on the right side of the radiator.
11. Disconnect the air hose on the right side of the radiator.
12. Disconnect the thermoswitch plug.
13. Turn out a bolt of fastening of the lower part of a radiator.
14. Remove a radiator, having submitted it upwards.
Vehicles with a five-cylinder petrol engine may have an additional radiator mounted directly in front of the engine. This applies to vehicles with air conditioning, a tow hitch or an extended cooling system. An additional radiator is connected parallel to the main one and thus increases the active cooling surface. Removing an additional radiator is carried out as follows:
15. Remove the engine mudguard.
16. Drain the coolant into an appropriate container.
17. Disconnect the coolant circulation hoses from the radiator.
18. Turn out one bolt of fastening of a radiator above and two bolts of fastening of its bottom part.
Cleaning
With the beginning of the summer season and at the end of it, the cooling fins of the radiator must be cleaned of insects. Otherwise, the cooling effect of the radiator will be reduced.
19. Open the hood. For vehicles with a five-cylinder engine, remove the protective radiator cap.
20. Apply insect remover to the part of the radiator where insect residues have stuck to, for example, «Summer screen», and let it take effect.
21. Rinse off the agent together with insects with a stream of water, supplying it from the opposite side of the radiator. The water pressure should not be strong. Do not use sharp tools or hard brushes. Possible damage to the rib plates.
22. Clean the radiator surface around the radiator filler neck, as well as the surfaces under the rubber gaskets, if any.
