VP Racing Cool Down™ coolant additive is proven to reduce your engine temps (by up to 30°F) & cylinder head temps (by up to 75°F) while improving coolant flow. It works for gas and diesel engines & is safe for all radiator systems. Cool Down is ideal for your racing and street vehicles, RV, & towing applications.
Our coolant additive lubricates all vital components & is approved by most race-sanctioning bodies. Just one 16-Oz. bottle treats 12-20 quart cooling systems. If you run straight water in your system, we recommend adding 50% more Cool Down. When using as a diesel coolant additive, use twice the usual amount of product to protect wet sleeve cylinder liners. For powersports vehicles, you'll want to use 2 oz. of Cool Down for every quart of coolant.
VP Cool Down treatments last one year or 30,000 miles, whichever comes first. We do suggest changing your coolant every two years.
Looking for maximum protection & performance for your cooling system? Use Cool Down with Stay Frosty® Hi-Performance engine coolant.

FREQUENTLY ASKED QUESTIONS ABOUT VP RACING COOL DOWN
Can you mix this additive with antifreeze?
Yes, you can. Cool Down works great with antifreeze. It is formulated for use with today’s OAT and HOAT-formula engine coolants. We recommend changing your coolant every 2 years.
How do I use Cool Down™?
Just open the bottle and add the contents straight into the radiator or coolant reservoir. If you have access to a radiator cap, pouring Cool Down directly into the radiator is the preferred method. One 16 oz. bottle will treat cooling systems of 12-20 quarts.
Will your coolant additive work in cold weather climates?
If used as directed, it shouldn’t disrupt the freeze protection provided by traditional antifreeze that contains glycol.
