BG Universal Cooling System Cleaner

USP has used BG Products in our own service department for years. we don't recommend products we haven't used ourselves. Over time, your cooling system accumulates scale, oil residue, and mineral deposits that reduce cooling efficiency and accelerate corrosion. Left alone, these deposits eat through inhibitors and start attacking the metal inside your engine. This cleaner strips all of it out. Use it before a coolant flush for the best results. Works in gas and diesel engines, and no neutralization is needed after. just drain, flush with water, and fill with fresh coolant.
