Overview
Zerex® Extended Life Antifreeze/Coolant patented formula has been charged with special inhibitors to protect your diesel engine from liner pitting and hard water scale deposits for longer engine life. With the addition of an extender product, you can go 6 years, 14,000 hours, or 600,000 miles without changing your antifreeze.
How It Works: Extended Life Antifreeze/Coolant uses the highest quality virgin ethylene glycol for freeze and boilover protection, and a patented hybrid organic acid corrosion inhibitor package to protect cylinder liners from cavitation and liner pitting and your engine from rust and corrosion.
How To Use
Due to the differences in cooling systems, Valvoline recommends that you refer to your vehicle owner's manual for instructions on changing your antifreeze.
