How to connect the water pipe to the car heater?

There are two valves on the engine block, which are respectively connected with the air inlet pipe and the exhaust pipe of the heater. After connection, the valve can be opened.

Warm air comes from the heat generated when the engine is working: when the cooling system of the engine radiates heat to the engine, the radiated heat is sent into the car through the fan to form warm air.

The water from the engine flows through the radiator of the heater through a valve. When the fan is started, the heat from the engine will be brought into the car, thus heating the car in winter.

Extended data:

Turn on the AC key when turning on the warm air. You don't need to touch the AC switch when using the car heater. Just adjust the air volume button to blow out warm air, without turning on the compressor.

Used properly, it will not produce oil consumption. Do not open the AC button, only use the heat in the car to circulate the warm air, without increasing fuel consumption.

When the outside temperature is low, the temperature of the water tank is also very low. Turning on the air conditioner will not immediately increase the temperature inside the car, but will also increase the burden on the engine and slow down the change of the temperature inside the car.

When the water temperature indicator reaches the middle, warm air can be used. The cold air in the car can be eliminated by external circulation first, and it is better to switch to internal circulation in about three minutes.

Aim the tuyere at the windshield and dry the water, so it won't fog.
