Cooling system specifications Type - Closed with forced circulation of the coolant. It consists of a radiator, an expansion tank, a water pump, a thermostat, an electric fan switched on by a thermal switch. An oil cooler is connected to the cooling...
General description and precautions The liquid circulating in the cooling system removes heat from the engine, cooling in the radiator, and also heating the passenger compartment. As a coolant, an agent with anti-corrosion and frost-protective properties...
Coolant — draining and refilling Filling the coolant is not just pouring coolant into the expansion tank. Some hoses through which the coolant circulates are located above the expansion tank. For this reason, the coolant is filled with a special...
Radiator — removal and installation Removal and installation of the radiator are carried out after dismantling the lining of the front of the car. Depending on the car model, the radiator block consists of the following parts (see illustrations 3.0 and...
Water pump — removal and installation The water pump is beyond repair. If the pump is not tight or the bearings are worn, the pump is replaced as a set. The water pump is driven by a toothed belt. This means that access to the water pump is possible only...
Removing the thermostat To remove the thermostat, it is necessary to drain the coolant from the system and disconnect the hoses from the fittings by loosening the fastening clamps. One hose leads to the oil cooler (if one is installed), and...
Cooling liquid At the factory, the system is filled with coolant, which is not recommended to be drained for a year, because it contains additives that protect the cooling system from corrosion and identical damage. When changing the...
Checking the thermal switches Thermal switches cannot be adjusted or repaired. The thermal switches are screwed into the thermostat housing and into the lower part of the radiator. You can check the operation of the thermal switch by lowering it...
Radiator fan The radiator blower fan can be replaced after the radiator has been removed. The need to replace the fan is unlikely. The radiator is removed together with the fan. When replacing a fan motor, remember that not all fan...
Coolant hoses When purchasing new coolant hoses, the engine number and year of manufacture must be specified. Typically, a fluid leak from a hose occurs on the way and you have to take emergency measures. Gas stations offer so-called...
