Pic. 333. Instrument cluster: 1 - coolant temperature gauge; 2 - fuel gauge with signal lamp; 3 - speedometer; 4 - tachometer; 5 - hours; 6 — clock setting button; 7 - odometer; 8 - button for resetting the daily mileage counter; 9 - indicators of outside temperature and the position of the automatic gearbox selector lever; 10 - control and signal lamps
In exceptional cases pointer arrow 1 (see fig. 333) may reach the red zone. At high temperatures, the coolant can boil in the system and under pressure. In this case, you should stop, turn off the engine and find out the cause of the malfunction. Possible reasons are as follows:
- the arrow may briefly enter the red zone when driving at maximum speed, uphill or in heavy traffic in hot weather - this is normal;
- the arrow may enter the red zone after stopping a hot engine;
- coolant pump failed (also check the drive belt);
- insufficient coolant level. Check and bring to the norm;
- stuck thermostat. To check, touch the radiator. If it is cold, and the thermostat, on the contrary, is hot, this is a sign of a jammed thermostat;
- check the operation of the cooling fan;
- the radiator is clogged, it needs to be cleaned.
Pic. 334. The right side of the line of control lamps: 1 - coolant level; 2 - direction indicators; 3 — a control lamp of system ABS; 4 — a control lamp of the ABD system; 5 — a control lamp of system SRS (airbag)
Pilot lamp 1 (pic. 334) the coolant level indicator should not light when the engine is running, otherwise add liquid to the expansion tank of the cooling system.
