1. Air tangki skala The air suhu dalam air tangki is selalu terawat at a tinggi suhu, yang akan menggabungkan the hidrokarbon radikal in the air dengan kalsium dan magnesium plasma ke bentuk air-tidak larut kalsium karbonat dan magnesium karbonat, umum diketahui sebagai air alkali. Lalu sebagai air berlanjut ke menguap dan konsentrat, the alkali konten dari air melanjutkan ke peningkatan dan jangkauan saturasi, pembentukan sisik.
2. Engine coolant The engine coolant takes away the heat generated by the engine, and at the same time supplies the heat to the interior of the car through the heater water tank to form warm air. If the engine coolant is lost, it will cause problems with the heater. First of all, we can Check to see if cooling is missing.
3. The engine temperature is too low. When the engine temperature is too low, the warm air in the car is not hot enough. It can speed up the vehicle, make the engine run faster, and increase engine temperature.
4. The thermostat is always open or the thermostat is opened too early, which causes the cooling system to perform a large cycle prematurely, and the outside temperature is very low. Especially when the car is running, the cold wind quickly cools the antifreeze and the engine water temperature does not rise. Come on, the warm air won't make you hot.
5. Lack of antifreeze. Terutama in some cars, the heater air will be hot when the gas pedal is opened, and the heater will not be hot when the gas pedal is not opened. The first thing to consider is the lack of antifreeze. It is a very simple problem. .
