* For any coolant and anytime you are changing coolant, we recommend a simple solution of distilled water and white distilled vinegar, both available at your local grocery store.
Mix the water/vinegar at 50/50
Fill system with the solution
Run engine until warm
Run clear water through to rinse out vinegar
Fill with coolant of choice
This is the same as cleaning your coffee maker. The vinegar is acidic enough to clean out and contaminants and residual coolants, yet it won’t harm your seals and gaskets.
