• Volume: 5 Litre
• Compatibility: For use with Classic Cool 180° and Vintage Cool 180°

Why Choose Evans Prep Fluid?

• Total Water Removal: Evans Waterless Coolants require a water-free environment to function. This fluid absorbs any remaining droplets trapped in the heater matrix or engine block after draining.
• Active Cleaning: Gently removes loose rust, dirt, and scale deposits that can impair heat transfer and clog radiator galleries.
• Optimised Heat Transfer: By cleaning the internal surfaces of the cooling system, it ensures your engine can dissipate heat as efficiently as possible.
• System Preservation: Safe for use in all classic engines, providing a clean slate that protects your new coolant from contamination and ensures its lifetime service.

Installation Tip: After draining your old water-based coolant, fill the system with Prep Fluid and run the engine until it reaches operating temperature (with the heater on). Drain the Prep Fluid thoroughly before immediately filling with your chosen Evans Waterless Coolant to prevent moisture from re-entering the system.

Key Point: This fluid is essential for a successful conversion, ensuring no residual water remains to compromise the new coolant.
