VP Cool Down™

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.

Take a look at what happened when Engine Labs put Cool Down to the test on a 2006 C6 Corvette.

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.
