Flushing the Coolant System

Flushing your coolant system removes old coolant and debris. Follow these steps:

Replacing the Coolant

Now that the system is flushed, it’s time to replace the coolant. Follow these steps:

Disposing of Old Coolant

Old coolant is toxic and should be disposed of properly. Here’s how:

  • Transfer the old coolant from the drain pan into a sealed container.
