Here are the steps on how to use the Sealey AK4122:

1. Remove the cap from the antifreeze reservoir.
2. Insert the probe of the AK4122 into the antifreeze reservoir.
3. Squeeze the trigger on the AK4122 to dispense a small amount of antifreeze onto the dial.
4. Read the freezing point and concentration of antifreeze on the dial.
5. Replace the cap on the antifreeze reservoir.

If the freezing point of the antifreeze is below the expected temperature for your area, you will need to add more antifreeze to the reservoir. If the concentration of the antifreeze is below the recommended level, you will need to add more antifreeze to the reservoir.

It is important to test the antifreeze in your vehicle's cooling system on a regular basis, especially before the start of the cold weather season. This will help you to ensure that your vehicle's cooling system is properly protected from freezing temperatures.
