VP Racing Fuels 2085 Cool Down Coolant Performance Improver, 16 Ounces

Excellent product. It made my 1940 Chevy Streetrod run much cooler. Especially with the AC on.

Easy to use. Time will how well it works. No problems or issues,

Used in a mid 80s muscle bike. Whole bottle with distilled water only. Runs cooler without antifreeze. Never use bike in freezing weather. Worth the money spent.

I was unsure of its claims, but sure enough, it dropped my coolant temp in my old dodge by at last 10 degrees.

Didn't drop temps at all

I've been adding 1 bottle of this Coolant Additive to Both my SUVs every Summer and it makes the Engine Slightly Cooler so the AC doesn't have to work as hard as if w/o it! Easy to use: just pop your Radiator Cap (obviously when the Engine is COOL!) and pour the contents into the Reservoir Tank... 👍😃✔️

Did not get a cooler motor at all. Didnt work at all

Use this product all the time. Works great.
