How to replace Buick Angola antifreeze (replacement method of Angola antifreeze)
Buick Angola antifreeze replacement tutorial
1. Stop for a period of time to prevent being scalded by antifreeze. Unscrew the drain valve at the bottom of the water tank until the antifreeze is completely discharged.
2. It is necessary to keep the vehicle running at idle speed, continuously inject fresh water into the antifreeze storage tank, and continuously flush the residual antifreeze in the cooling system. When the water flow has no color, the filling can be stopped, and the old antifreeze is basically discharged.
When the water doesn't flow out, you can install a drain valve to shut down the engine. Pour new antifreeze into the storage tank, and the liquid level scale line should be between MAX and MIN, or even a little more.
4. Start the engine for inspection. When idling, the air is driven away from the cooling system, and the liquid level of antifreeze will drop by a certain distance.
5. After the liquid level is stable, add antifreeze between MIN and MAX to complete the replacement process of antifreeze.
Buick Angola has added more ways to release antifreeze.
1. It is a relatively simple method to use a syringe, and the spare antifreeze is pumped out with distributed thin tubes.
2. The drain valve is located on the water pipe below the cooling fan and can be unscrewed to release excess liquid. (It is not recommended that the owner try it himself. There is a pressure difference in the water tank, and the pressure relief process itself is very dangerous. Moreover, the position of the water pipe drainage screw is hidden and difficult to operate. )
