Jetta's air conditioner emits a lot of white smoke! Ask for an answer!
After parking, the leakage is faster than after parking, because the water pump will be forced to run after parking, especially when the water temperature is high, the pressure of the cooling system will increase and the leakage of antifreeze will accelerate.
If the heater water tank is not replaced as soon as possible, the damage may be aggravated. Too much or too little coolant will dilute the lubricating oil after the engine is at high temperature, which will affect the lubrication effect, further lead to the temperature rise of moving parts, and then lead to a vicious cycle, which will have adverse effects on the engine system, such as the locking of piston and cylinder and the locking of crankshaft bushing. And the maintenance cost is high.
You can confirm that the leak is serious, immediately pull over, turn off the vehicle, and call your insurance company to call for a trailer (now many policyholders who have paid commercial insurance can tow the truck unlimited times, please consult the insurance company for details). If you encounter a small amount of liquid leakage, but the water temperature meter gives an alarm at high temperature, you can add clean tap water for temporary emergency, and then go to the repair shop to check and replace the leaked parts as soon as possible. After draining the coolant as much as possible, add antifreeze produced by regular manufacturers, thinking about the maintenance certificate. This maintenance is guaranteed. After the repair, pay attention to the liquid level change of the coolant expansion pot in the engine room to ensure that the closed cooling system is well sealed.
