Frequently Asked Questions

How long does it take to flush a cooler?

ANSWER: On the average most coolers are clean within an hour, it can be as little as 15 minutes or up to a couple hours. The point is, you decide because you're going to see all the debris as it's coming out. Debris that you never realized was in the cooler!

Do I have to change the fluid in the machine every time I flush a vehicle?

ANSWER: No. On average you'll change the fluid (2 gallons) after 50 to 60 flushes. By filtering through the 28 micron checkable screen and the 10 micron reservoir filter, the fluid stays clean.

How often do I have to change filters on the machine?

ANSWER: The reservoir filter can be changed monthly, the 28 micron screen will last several years with proper use.

How do I know when the cooler is clean?

ANSWER: By flushing, checking & cleaning the screen until it stays clean after flushing.
