Is It Normal for a Car to Drip Water When the Heater Is On?

[CodyMarie]

It is not normal for a car to drip water when the heater is on. Below are the relevant details: Reasons for water dripping when the car heater is on: Metal pipes may leak due to rust, welding cracks, or vibration-induced cracks. Rubber pipes may leak due to poor resistance to temperature differences or pulse pressure differences. If there is a leak at the connection between metal and rubber pipes, the clamp may need to be replaced or the connection reinstalled and adjusted. Precautions when using the car heater: When using the heater, it is best to use the external air circulation mode. In winter, the temperature difference between the inside and outside of the car is significant, which can easily cause fogging on the windows. Many car owners know that pressing the window defogging button will automatically direct cold air toward the windshield, eliminating the fog. First, start the engine and drive normally. After warming up for a while, when the temperature gauge needle reaches the middle position, turn on the heater. Set the air circulation to external mode to let cold air escape from the car. After 2-3 minutes, switch to internal circulation. This will quickly warm up the car interior without putting a burden on the engine.
