Each automobile manufacturer has specific requirements for antifreeze that depend upon the predominant engine design that manufacturer uses. These manufacturers required a specific (Disodium Fluorescein) color dye to help mechanics differentiate what is in the radiator system already as wel as help trace the source of leaks.
Even though our antifreeze / coolants have dyes, the best thing about Timberline Products LLC’s antifreeze / coolant products is that the base product is exactly the same no matter what dye is used. An remember, our antifreeze / coolants are all ECO-friendly made from Propylene Gylcol and Glycerin. Please see another one of our FAQ’s, “Can original manufacturer warranties be voided by using Timberline antifreeze coolant products?” for information about the original manufacturer warranties and how Timberline Products LLC’s products work with them.
