Coolant temperature gauge
The coolant temperature gauge in the engine cooling system is located in the instrument cluster and only works when the ignition is on.
At a high ambient temperature, the pointer arrow may come close to the border of the red sector. However, if the arrow gets too close to the red sector or even enters it, you should stop the car and find out the reason for such a high temperature, which may be next.
- low fluid level in the engine cooling system (there are leaks),
- the ventilation holes between the radiator fins are clogged with dirt, or too much scale has formed inside the radiator.
- cooling fan does not work.
- defective thermostat,
- the ignition is incorrectly adjusted.
CAUTION: Operating an overheated engine (the arrow of the temperature indicator is constantly in the red sector of the scale) may cause serious mechanical damage.
Coolant level
The coolant level in the expansion tank is checked on a cold engine at least once a week. After the first 2,500 km of run, then every 10,000 km of run, but at least once every two years, the percentage composition and level of the coolant, the condition of the hoses and the absence of leaks at their joints should be checked.
The coolant level in the expansion tank is visible through its transparent walls and should be at the height of the mark «max». If necessary, add coolant to the system through the filler neck of the expansion tank.
ATTENTION
1. When removing the expansion tank cap on a hot engine, first unscrew it to the first stop, relieve pressure in the system and remove the cap completely after a few seconds.
2. In the event of a significant shortage of coolant, do not add cold coolant to a hot engine (antifreeze or water).
3. If there is an electric fan controlled by a thermal switch in the engine cooling system, you must first turn off the ignition.
Coolant replacement
Every two years of operation of the car, it is necessary to flush the cooling system from scale and replace the coolant.
