Important: Properly prepare the system with Prep Fluid

Switching to Hawk Power Cool 180° requires proper preparation of the cooling system if the engine contains or has contained water-based cooling fluid. Simply draining the system generally does not remove all the water present in the engine.

Water may remain in the engine block, cylinder head, radiator, heater, and certain lines. Filling the system directly with Power Cool 180° would contaminate the new fluid and reduce the benefits of water-free operation.

The conversion must therefore be performed first using Hawk Prep Fluid 5L. Thanks to its hygroscopic properties, the Prep Fluid removes residual water before the final fill with Power Cool 180°.

After conversion, Hawk recommends that the residual water content be ideally 3% or less. This value can be checked using a refractometer.

Why use a waterless cooling fluid in a high-performance engine?

A sports or tuned engine can generate significant thermal stress, particularly when it is turbocharged, heavily loaded, or used in competition. Certain areas of the cylinder head can then reach extremely high temperatures.

With a standard cooling fluid, steam can form locally in these areas. A vapor lock is an inefficient medium for heat dissipation: the cooling fluid is no longer in direct contact with the metal surface, and localized hot spots may develop.

These phenomena can lead to overheating and are a major factor contributing to cylinder head gasket failure.

With a boiling point exceeding 180°C, Hawk Power Cool 180° significantly limits vapor formation and allows the fluid to remain in contact with metal surfaces at temperatures at which a standard cooling fluid may begin to produce vapor.

Less pressure and cavitation in the system

Hawk reports a vapor pressure 75% lower than that of a water-based cooling fluid. This drop in vapor pressure helps minimize the stress placed on hoses, gaskets, and other components in the cooling system.

Cavitation is also reduced. Hawk reports a 75% drop in cavitation erosion compared to water-based fluids. This feature helps protect the water pump and components exposed to high-velocity fluid flow.

Why choose the 25-liter container?

The 25-liter container of Hawk Power Cool 180° is specifically designed to meet the needs of professionals and users who require large volumes. In particular, it allows users to perform multiple conversions or refills without having to purchase multiple smaller containers.

It is therefore an ideal solution for specialized workshops, automotive tuners, racing teams, motorsports professionals, or owners of multiple vehicles that use Power Cool 180°.

The actual volume required must always be determined based on the total capacity of the vehicle’s cooling system.

Evans Power Cool Becomes Hawk Power Cool

Evans Waterless Cooling Fluid is now known as Hawk Waterless Cooling Fluid. The former Evans Power Cool 180° waterless cooling fluid is now marketed under the name Hawk Power Cool 180°.

This change is limited to the brand name; the product formulation remains unchanged. Users already familiar with Evans Power Cool will therefore find this same formulation under the new Hawk brand.

GT2i is an official dealer of Hawk Waterless Coolants and offers waterless cooling fluids as well as the products needed to prepare and convert the cooling system.

How do you convert an engine to Hawk Power Cool 180°?

Start by draining as much of the old cooling fluid as possible. The cooling system must then be prepared with Prep Fluid to remove any water remaining in the engine after this initial drain.

Use the 5L Hawk Prep Fluid to perform this preparation. Once the procedure is complete, the Prep Fluid must be drained before the system is finally filled with Power Cool 180°.

Once properly converted, the system is filled with Hawk Power Cool 180° without any dilution with water. The product must never be intentionally mixed with water, as this reduces the benefits intended with a waterless cooling fluid.
