Is there air, warm air and heating in the regal water tank?

Regal water tank of Pacific Auto Network is heated by air, and the vehicle heating system is not hot, which is divided into two reasons: 1, engine cooling system; 2. The control mechanism of warm air doesn't work well.

Air can be exhausted from the repair shop.

The way to exhaust the Buick Regal water tank is to add water from the auxiliary water tank. Open the water tank cover on the water tank and press it with your palm. Unscrew the exhaust screw at the upper water pipe. Add water from the auxiliary water tank until the water starts to flow out at 2 and 3. The maintenance method of water tank is as follows:

1. Stop the car and turn off the engine. When the coolant temperature drops, open the expansion kettle and fill it with water tank cleaner.

2. Start the engine until the cooling fan works, and then idle for 5- 10 minutes;

3. Turn off the engine and remove the front bumper of the vehicle.

The vehicle heating system is not hot for two reasons:

One is caused by the engine cooling system,

First, the control mechanism of warm air is not easy to use.

First, the thermostat is always turned on or turned on too early, which makes the refrigeration system carry out a large cycle prematurely, while the outside temperature is very low and the warm air will not be hot.

Second, the water pump impeller is damaged or lost, so that the flow through the warm air small water tank is insufficient and the heat cannot come up.

Analysis of Buick LaCrosse's warm air is not hot: there are two reasons why the vehicle's warm air system is not hot:

One is caused by the engine cooling system,

First, the control mechanism of warm air is not easy to use. When maintaining, it is necessary to determine what causes it first, and then carry out corresponding maintenance. The method of discrimination is simple. Look at the temperature of the two inlet pipes of the warm air small water tank. If both pipes are hot enough, there is something wrong with the air flow control mechanism. On the contrary, if both pipes are cold, or one is hot and the other is cold, it is a problem with the cooling system.
