Redstone: As for your question, the cylinder gasket leakage of Fukang car is common, and the cylinder gasket of new 16v engine also leaks, and the loss of antifreeze will be greater after the cylinder gasket is damaged. The odor after the warm air is turned on should have little to do with the warm air small water tank, which has only two joints, so there is generally no leakage, and the odor may be related to the unclean air duct. For family cars, it is normal to add about half a liter of antifreeze for half a year or 20 thousand kilometers. When the engine is turned off, the liquid level of antifreeze will be different when the car is cold and hot. This is a normal phenomenon, please feel free to use it.
