We formulate VP ULTRA POWER™ RED ELC Heavy Duty Antifreeze and Coolant for diesel semi trucks, construction equipment, and agriculture equipment. It delivers total diesel cooling system protection for most heavy-duty engines.

To begin with, we use a proprietary nitrited-hybrid organic acid inhibitor (NOAT/HOAT) in our diesel antifreeze/coolant that meets and exceeds most universal heavy-duty coolant applications. As a result, it delivers superior corrosion protection of system metals. This includes steel, aluminum, cast iron, copper, brass, and solder.

Additionally, our antifreeze coolant includes a unique combination of carboxylic acids (OAT) and nitrites. This protects diesel engine wet sleeve cylinder liners from pitting and cavitation. It also allows for extended service intervals and eliminates the need to use supplemental coolant additives. ULTRA POWER RED minimizes maintenance costs, helps eliminate downtime, and extends equipment life.

For total protection of your heavy-duty engine, try our diesel engine oil, ULTRA POWER Heavy-Duty SAE 15W-40. It affords optimum fuel economy and delivers superior wear protection.
