IT IS ESSENTIAL THAT THE HAWK PREPARATION FLUID IS USED TO REMOVE ANY RESIDUAL WATER BASED COOLANTS AND TO CLEAN THE SYSTEM PRIOR TO THE FITMENT OF HAWK WATERLESS ENGINE COOLANT.    THE ONLY EXCEPTION WHERE PREP FLUID IS NOT REQUIRED IS IF IT IS A NEW ENGINE BUILD AND A NEW RADIATOR.

Why is it good for classic cars ?

Most new customers wanting to use Hawk will need to remove the existing water based coolant from their system. To gain maximum benefit from Hawk, we recommend that no more than 3% residual water is present in the coolant. To help achieve this we have formulated a hygroscopic Prep Fluid designed to flush the system before adding Hawk.

HOW DOES IT WORK ?

Fill the freshly drained cooling system with Hawk Prep Fluid and run the engine up to normal operating temperature. The hygroscopic fluid will absorb any residual water and flush out any loose deposits.

WHAT SHOULD I DO WITH IT THEN ?

Once the Prep Fluid has been drained from the system, store it in an airtight container as it can be used several times.
