Warning! Do not open the radiator cap when the engine is hot, as the cooling system is pressurized and opening the cap can cause hot fluid to escape, which can cause severe burns. Wait until the engine has cooled down before opening the radiator cap.
Transition of the pointer of the device from the allowable range towards the position "H" indicates engine overheating, which could damage it. Open the hood and check the coolant level in the expansion tank and the condition and tension of the water pump drive belt.
