Evans EC42001 Prep Fluid: Getting your Car Ready for Waterless Coolant

Converting your cooling system to a high-performance, water-free coolant like Evans Arctic or High Performance provides superior thermal protection and corrosion resistance. However, without properly preparing the system, trapped water and residual antifreeze can compromise results. This is where Evans EC42001 Waterless Coolant Prep Fluid becomes essential; it actively removes water and deposits to meet the sub‑3% system water requirement.

Why Prepping with EC42001 Matters

Evans waterless coolants rely on no water content to operate at boiling points above 375 °F, with no vapor lock, corrosion, or pressure spikes. But old systems often retain "bound water" and scale that regular drains don’t eliminate. EC42001 uses hygroscopic chemistry to seek and extract this residual moisture, protecting your engine from performance degradation or damage after conversion.

Designed for Professional Use

Built for commercial, industrial, and OEM applications, EC42001 is non-toxic, glycol-free, and safe on all cooling system metals like aluminum, iron, copper or brass and seals. It’s used by fleets, marine operators, and racing teams to ensure clean, water-free systems before installing waterless coolant.

Simple, Effective Flush Procedure

1. Drain existing coolant completely.
2. Fill with EC42001 Prep Fluid and run engine at operating temperature for 10–30 minutes.
3. Drain system again; repeat if high water content detected.
4. Allow system to cool, air purge, then fill with chosen Evans waterless coolant.

Following this process ensures your converted system reaches the Evans standard of less than 3% water which is essential for full system performance and longevity.

Engine Protection & Longevity

Once flushed and filled correctly, your engine benefits from Evans’ waterless coolant advantages: corrosion-free performance, boil-over protection, and lower system pressure: no top-offs needed. EC42001’s involvement in this system results in reliable, low-maintenance cooling, even in harsh environments.
