Will the leakage of automobile warm air affect the damage of other parts of the engine?

Hot air leaks. It is rare to hear that the heating is leaking. If it leaks, go to the 4S shop, it is necessary to repair it! ! Because there are two sources of warm air,

1: just use local materials, that is to say, directly use the heat in the engine! ! This heat is the hot air emitted by the coolant, and then it is sent to the car by the blower! !

2, it is the heating wire, which is not difficult to understand! ! !

The problem is 1. According to common sense, there will be water in cold air and there will be no water in hot air. If there is, it may be hot air. There is something wrong with the valve that controls the hot air source. What's its name? I haven't repaired the car for so long, I forgot. Ha ha! ! ! In addition, water can be a coolant, which has multiple functions and is oily. 1 fast heat dissipation, 2 anti-corrosion, 3 leak-trapping, 4 high pressure resistance, etc. I don't remember ...

The shopkeeper still goes to the 4S shop to see it! !
