|1. Many gross infringements in engine work are connected with malfunctions of system of cooling. If the car is equipped by automatic transmission its functioning and service life also directly are connected with work of system of cooling.|
|2. Check of system of cooling should be made at the cold engine, therefore is better be engaged in it before the first trip for a present day or not earlier than in three hours after engine deenergizing.|
|3. Slowly, being careful in case the engine has not absolutely cooled down yet, uncover a radiator. Carefully wash out it from within and outside of pure water. Also wash out a jellied mouth of a radiator. Presence of traces of corrosion in a jellied mouth means that it is necessary to replace a cooler (address to subsection Replacement of a cooling liquid). The cooler in a radiator should be rather pure and transparent. If it has brownish colour, drain system and fill in in it a new cooler.|
|4. Carefully check up radiator hoses, and also hoses of a heater which have smaller diameter. Check hoses of system of cooling on all length, making replacement of any burst, blown up or worn out hose. Cracks are easier for finding out if to compress a hose a hand. Will pay special attention on the collars keeping hoses on components of system of cooling. These collars can cut or pierce hoses that will lead to cooler leak.|
|5. Make sure of reliability of fastening of all шланговых connections. Cooler leaks are usually shown in the form of white or rusty colour of adjournment in the field of hermetic sealing infringement. If on your car collars of wire type it is possible are used, there is a sense to replace them with collars of screw type.|
|6. By means of compressed air or a soft brush clear a forward part of a radiator (and also the condenser of the conditioner of air, there, where it is available). Remove all insects, leaves and the other extraneous subjects which have got on edges of a radiator. Be very cautious not to damage an edge and not to cut about them fingers.|
|7. If cooler level constantly falls, and you have not found out any leaks, it is necessary to make check by pressure of a cover of a radiator and all cooling system.|
|Check of frost resistance of a cooling liquid |
Do not suppose antifreeze hit on your skin and the painted surfaces of the car. At hit immediately wash off a plentiful quantity of water. Antifreeze is extremely toxic and mortally dangerous at hit in an organism. Do not leave antifreeze in the open container or spilt on a floor; its sweetish smell can easily involve in itself children or pets. Consult about local rules of recycling of the fulfilled antifreeze. In many areas there are special centres on its acceptance.
|Before the beginning of a winter season it is necessary to check up necessarily concentration of antifreeze in a cooling liquid, especially if in system pure water was while in service filled in.|
|The demanded special tool:|
– A frost resistance measuring instrument. There is also an optical device for check of level HAZET № 4810.
Demanded operational materials and spare parts:
— With a protection frame from corrosion «G12» (red colour, the designation «G 012 А8D agrees TLAUDI 774 D») and pure, not containing to exhaust antifreeze water.
|8. Slightly warm up the engine so that the top hose of a radiator has heated up. At measurement of concentration of antifreeze the liquid temperature should make nearby +20°С.|
|The remark on security measures|
At the hot engine the stopper of a broad tank should be opened cautiously. There is a danger of a burn! It is necessary to put a rag on a stopper. A stopper open only at temperature of a liquid no more + 90°С.
|9. Cautiously turn away a stopper of a broad tank.|
|10. Type a liquid by means of a pear ареометра.|
|11. In our widths the concentration of antifreeze providing protection of system to temperature-25°S is sufficient, at especially frigid climate to-35°S.|
|In need of protection of the engine to temperature-25°S concentration of antifreeze in a cooling liquid should make 40 %. In need of protection to temperature-35°S concentration of antifreeze should make 50 %.|
If higher degree of protection against freezing is required, it is possible to raise level of concentration of antifreeze to 60 %. Such concentration will provide protection to-40°S. If concentration raises to higher level, degree of protection of the engine starts to go down and, besides, heat-removing properties of a cooler worsen.
|At cars to chassis number «8LVA006233» (a date of issue approximately till the end of 1996) is serially applied antifreeze of cooling liquid G11–ABC or any other antifreeze with a mark «agrees TL–VW 774 C». He can be learnt on green colour.|
|Since chassis number «8LVA006234» antifreeze AUDI G12 is serially applied. To system filling it can be applied G12 or any other antifreeze with a mark «it agree TL–VW 774 D». Antifreeze G12 has red colour.|
G11 And G12 it is not supposed to mix. It can lead to heavy damages of the engine. (Mix G11 and G12) it is necessary to replace cooling liquid of brown colour immediately.
The engines intended for use G11, can be translated on modified antifreeze G12.
|12. Close a stopper on a radiator and after a trial trip again check up concentration of antifreeze, thus address to Specifications.|
