You are able to spray brake fresher onto the series to enable you to wash it in case need be.

The hose must be long enough to enable you to link :

it to the port without putting the can right within the motor bay.

Six Use the surrounding air pressure chart over the gauge to establish stress. Read the gauge screen while snapping the surrounding temperature into consideration to find out what level the refrigerant is now at. When you start spraying, you are going to need to monitor the gauge to figure out once the method is full.[11]
Keep a watch on the gauge all through recharging the method to know when you should stop.
