Not all coolants are compatible — and mixing them can lead to more than just discoloration.
Testing shows that combining different coolant chemistries (IAT, OAT, HOAT) can create gel-like residue that restricts flow, reduces heat transfer, and leads to unstable temperature control.
In real-world conditions, this can result in:
✔ Overheating
✔ Restricted circulation
✔ Poor heater performance
✔ Repeat cooling-system issues after parts replacement
What looks like a component failure may actually start with coolant instability.
