We formulate VP Cool Down coolant additive for both gas and diesel engines. It's safe for all radiator systems and is ideal for racing, street, RV, and tow vehicle applications. In fact, it increases coolant flow for better heat transfer.
Our product not only reduces cylinder head temperatures by up to 75°F but engine temps by up to 30°F! Furthermore, it lubricates all vital components and is approved by most race-sanctioning bodies.
One 16-Oz. bottle of VP Cool Down treats cooling systems of 12-20 quarts. We recommend adding 50% more VP Cool Down for straight water applications. Additionally, diesel applications require twice the usual amount of product.
Cool Down treatments last one year or 30,000 miles, whichever comes first. We do suggest changing your coolant every two years. Moreover, when using it as a diesel coolant additive, we recommend using twice the suggested amount for complete protection of wet sleeve cylinder liners. Another key point is that you should use 2-Oz. of Cool Down for every quart of coolant for Powersports applications.
Another good point is that our coolant additive is a great compliment to 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. the 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.
