How to Safely Switch Coolants Without Damaging Your Cooling System


Posted November 5, 2025 by Sinoyqx

Switching engine coolants can be risky if done incorrectly. Learn how to safely drain, flush, and refill your cooling system using InnoChill TF150B — the eco-friendly, high-performance coolant designed for modern vehicles and extreme climates.

 
Understanding Coolant Compatibility
Coolants come in various chemical bases — IAT, OAT, and HOAT — each with distinct inhibitors and pH balances. Mixing different coolant types can trigger precipitation, foaming, or gel formation. Before switching, always check your vehicle’s manual and compare base chemistry and inhibitor composition. InnoChill TF150B is a universal, silicon-free, amine-free, phosphate-free coolant, compatible with most global vehicles.
Step 1: Drain the Old Coolant Completely
Ensure the engine is cool before opening the radiator drain plug. Let the coolant drain fully into a suitable container and dispose of it according to environmental regulations.
Step 2: Flush the System Thoroughly
Flushing removes rust, deposits, and residual additives that may react with the new coolant. Use clean water or a radiator flush until the drained liquid runs clear.
Step 3: Match the Specifications Before Refilling
Always check the technical specifications of the new coolant — pH value, freezing point, and inhibitors. InnoChill TF150B offers freezing protection down to −45°C, stable pH (7.5–8.5), and long-term corrosion protection.
Step 4: Refill and Bleed the Cooling System
Refill using the correct coolant-to-water ratio (typically 50:50). Run the engine with the heater on high to release trapped air and ensure even cooling.
Step 5: Monitor for Signs of Mixing or Contamination
After driving, check the coolant’s color and clarity. Cloudiness may indicate contamination. InnoChill TF150B’s advanced additive package resists degradation and maintains clarity.
