air expansion tank

The Expansion tank for car works to balance the cooling system pressure, and it also acts as a water refill. When the vehicle is started for the first time, the coolant of the cold water pressure tank will be sucked into the main water tank for cooling and heat dissipation of the engine. When the pressure of the whole cooling system is too high, the coolant in the main water tank will return to the water heater expansion tank pressure to reduce the pressure on the main water tank. The auxiliary water tank mainly plays the role of balancing the pressure of the cooling system, and it will also play a role in replenishing water. When the vehicle is first started, the coolant of the secondary water tank will be sucked into the main water tank for cooling and heat dissipation of the engine, and when the pressure of the entire cooling system is too high, the coolant in the main water tank will return to the secondary water tank to reduce the pressure of the main water tank.
