to Evans

Converting your vehicle to Evans Waterless Coolant is a straight forward process and should take about an hour. Evans works best when there is less than 3% water in the cooling system so it is important to remove as much water as you can.

Draining the coolantDraining the System

whilst not essential we would recommend the engine is run until warm. This will help ensure any sediment is partially loosened and coolant viscosity lowered. Drain the existing coolant from the entire cooling system including the heater matrix and all hoses. Remember that antifreeze is toxic and should be collected and disposed of responsibly.

Tips & Tricks
Blowing low pressure compressed air through the system after draining can help remove any coolant that remains within dead legs etc. Jacking the car so that it is angled toward the drain plug will also help.

To further ensure that the cooling system is as free from water as possible we recommed Evans Prep Fluid. This hygroscopic fluid absorbs any residual water and removes any loose dirt and scale. Fill the system with Evans Prep Fluid and run the engine until normal operating temperature is reached. Allow to cool then redrain.

Tips & Tricks Once you have drained the Prep Fluid store it in an air tight container as it can be used several times.

Fill the system with the appropriate Evans coolant. Run the engine until normal operating temperature is reached to displace any trapped air. After the initial fill check the coolant level and top up if necessary.

Provided the system is not left open to the atmosphere or accidentally contaminated with water it will last the life time of the engine. Forget longlife, Evans is 4life!
