Questions about this item

Which size should I choose for my cooling system?

The bottle contains one pint and treats up to four gallons of coolant, so select this size when your system capacity is near that volume.

What does the freezing point of 24.8 degrees F mean once the additive is mixed?

It indicates the lowest temperature the treated coolant will resist freezing, protecting the system in cold conditions.

How does the pH level of 10.5 affect the cooling system in practice?

A maximum pH of 10.5 helps maintain alkaline reserve, reducing corrosion and scale formation inside the engine and radiator.
