The cooling system of the engine is blocked by air, which leads to the abnormal operation of the cooling circulation system of the automobile and the problem that the warm air is not hot. If the inlet pipe of the warm air small water tank is hot and the outlet pipe is cold, it means that the small water tank is blocked and needs to be replaced. The damaged or lost water pump impeller of the vehicle reduces the amount of water in the water tank, resulting in the warm air not being hot, so it is necessary to replace the new water pump impeller.
Pay attention to the use of car warm air
It should be noted that turning on the heater in winter will not increase fuel consumption, so the heater may always be on and never turned off, even after the car stops. In fact, this is very harmful to the car. When you start the car, because the engine needs to drive the condenser and blower to start together, the fuel consumption will definitely increase at this time, and it will also lead to battery loss.
Users need to pay attention to turn off the heating when not in use. Even if the car is always on, it is not suitable for continuous heating, which will cause damage to the condensation system. It is suggested to shut down for a few minutes after 1 hour.
