Why is the new sagitar warm air not hot?

1, the thermostat is always on or the thermostat is turned on too early, which makes the cooling system carry out a big cycle prematurely, and the outside temperature is very low, especially when the car is driving, the cold air quickly cools the antifreeze, the engine water temperature does not rise, and the warm air does not heat up.

2. The water pump impeller is damaged or lost, so that the flow through the warm air small water tank is not enough, and the heat can't come up.

3. There is air resistance in the engine cooling system, which leads to poor circulation of the cooling system, resulting in high water temperature and lukewarm air. If there is gas in the cooling system all the time, it is likely that the cylinder pad is damaged and the gas leaks into the cooling system; If the inlet pipe of the small heating tank is very hot and the outlet pipe is very cold, this situation should be that the small heating tank is blocked and should be replaced.

Extended data:

1, check the hot and cold windshield to see if the air conditioner is adjusted to the hot windshield;

2. Check the electronic fan temperature control switch;

Generally speaking, the vehicle heating system is not hot, which can be divided into two aspects: one is caused by the engine cooling system, and the other is caused by the failure of the heating control mechanism. These problems are more difficult than ordinary car owners, and some of them are more complicated to maintain, so you should consult professionals.
