Check of functioning of system of cooling and frost resistance of cooling liquid 1 Many serious violations in operation of the engine are connected with malfunctions of system of cooling. If the car is equipped with automatic transmission, its functioning and service life also are directly connected with work of system of cooling.2 Check of system of cooling should be made at the cold engine therefore it is better to be engaged in it before the first trip for the present day or not earlier than in three hours after engine switching off. 3 Slowly, being careful in case the engine yet absolutely cooled down, uncover a radiator. Carefully wash out it from within and outside pure water. Also wash out a jellied mouth of a radiator. Existence of traces of corrosion in a jellied mouth means that it is necessary to replace a cooler (address to the Section Replacement of cooling liquid). The cooler in a radiator should be rather pure and transparent. If it has brownish color, drain system and fill in in it a new cooler. 4 Carefully check 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 if to compress a hose a hand. Pay special attention to the collars holding hoses on components of system of cooling. These collars can cut or pierce hoses that will lead to leakage of a cooler.
5 Make sure of reliability of fastening of all shlangovy connections. Leakages of a cooler are usually shown in the form of white or rusty color of deposits in the field of sealing violation. If on your car collars of wire type are used, it is possible, there is a sense to replace them with collars of screw type. 6 by means of the compressed air or a soft brush clear a forward part of a radiator (and also the condenser of the conditioner of air where it is available). Remove all insects, leaves and the other extraneous subjects which have got on edges of a radiator. Be very careful not to injure an edge and not to cut about them fingers. 7 If cooler level constantly falls, and you did not find 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 cooling liquid
Before the beginning of a winter season it is necessary to check surely concentration of antifreeze in cooling liquid, especially if in system pure water was in use filled in. For this purpose the frost resistance measuring instrument is required. There is also optical tool for check of level of HAZET No. 4810. Check 8 Slightly warm up the engine so that the top hose of a radiator heated up. At measurement of concentration of antifreeze the temperature of liquid should be close to +20°С.
9 Carefully unscrew a stopper of a broad tank.
11 In our widths the concentration of antifreeze providing protection of system to temperature – 25°С is sufficient, at especially frigid climate to – 35°С. Antifreeze addition Address to materials of Specifications at the beginning of Head. In need of ensuring frost resistance to temperature – 25°С concentration of antifreeze in cooling liquid should make 40 %. In need of ensuring frost resistance to temperature – 35°С concentration of antifreeze should make 50 %.
12 Remove necessary quantity of a cooler and add antifreeze according to data of Specifications. 13 Close a stopper on a radiator and after a trial trip again check concentration of antifreeze, address to Specifications. |
