Mobil Delvac™ Extended Life 50/50 Prediluted Coolant/Antifreeze
Mobil commercial-vehicle-lube , Peru
Product Description
Mobil Delvac Extended Life 50/50 Prediluted Coolant/Antifreeze is a ready to use phosphatefree, silicatefree, nitritefree and boratefree ethylene glycol base coolant that is designed to provide exceptional wet sleeve liner cavitation and corrosion protection of all cooling system metals.
Mobil Delvac Extended Life 50/50 Prediluted Coolant/Antifreeze is formulated with organic corrosion inhibitors to provide total cooling system protection for 1,000,000 miles of onroad use (8 years or 20,000 hours of offhighway use). Since the organic corrosion inhibitors do not readily deplete, Mobil Delvac Extended Life 50/50 Prediluted Coolant/Antifreeze eliminates the need for Supplemental Coolant Additives (SCAs) as required when using conventional coolants.
Mobil Delvac Extended Life 50/50 Prediluted Coolant/Antifreeze is a 50/50 mix of Mobil Delvac Extended Life Coolant/Antifreeze and deionized water.
Features and Benefits
- Long Service Life: 1,000,000 miles of onroad use (8 years or 20,000 hours of offhighway use)
- Designed for use in engines running EGR and SCR technologies that can increase cooling system temperatures
- Eliminates the cost of SCAs, test strips and manpower required to test the coolant and add SCAs
- Can accept up to 25% mixing with conventional coolant technologies, with no detrimental effect to corrosion protection or reducing the extended life properties
- Fully compatible with other quality Organic Acid (OAT) and Nitrited Organic Acid (NOAT) heavy-duty extended life coolants
- Nonabrasive formula can improve water pump seal life
- Optimal hard water compatibility and reduced hard water scale
- Provides outstanding long-term elastomer compatibility
