Fleetguard ES Compleat OAT Concentrated Organic Lifetime Coolant, 1 gallon
Part #: FG-CC36073
  Price $30.24

Fleetguard ES Compleat OAT (Organic Acid Technology) coolant from Cummins Filtration is a nitrite, amine and phosphate NAP (Nitrite, Amine, Phosphate and Silicate) free formulation. It does not contain borate or silicate, which makes it acceptable to most OEMs around the world. This new coolant is environmentally friendly and offers solid liner pitting and better aluminum protection than conventional OAT coolants containing nitrite.

ES Compleat™ OAT (Organic Acid Technology) is an organic acid fully formulated extended life Ethylene Glycol (EG) antifreeze/coolant. It is the answer to the maintenance demands of heavy duty diesel cooling systems. ES Compleat OAT EG may be used with Extended Service Interval (ESI) water filters and ES Compleat OAT Extender and only requires reinhibition after three years, 300,000 miles (500,000 km), or 6,000 hours of operation. ES Compleat OAT Extended Life Antifreeze/Coolant utilizes patented organic acid technology. It provides superior diesel engine protection against freezing, boil-over, cavitation, liner pitting, erosion, corrosion, elastomer gasket degradation, and scaling, with one replenishment of ES Compleat OAT Extender liquid. With extended service intervals of 300,000 miles (500,000 km) or 6,000 hrs, ES Compleat OAT offers freeze protection to -34° F and provides ultimate liner pitting, corrosion and aluminum protection for longer system life.

ES Compleat OAT coolant meets ASTM and performance specifications of most major OEMs, including Cummins,
Detroit Diesel, MAN, Volvo, MACK and International.

We sell
ES Compleat OAT in the concentrated bottles to keep your shipping cost down. All you need to do is purchase the same number of bottles of distilled water at your local supermarket. Just add one bottle of Concentrated ES Compleat OAT followed by one bottle of distilled water and repeat until your system is full.

• This item is concentrated. You add the water.

To protect your engine against wear, Cummins Filtration recommends:
Coolant filtration - proven to reduce wear and optimize cooling system performance. This is especially important for coolants that stay in the engine longer.
Avoid Unnecessary Drains - The useful life of a coolant ends when the chemical additives in the coolant are outside acceptable limits. This is typically caused by topping off with a concentrate or water only. When adding coolant to your system it should be done with the correct mixture (typically 50/50) of the same coolant in your system currently.
Contaminants in coolant exceed published condemnation limits – which is likely only in unusual circumstances. Cooling system monitoring tools can help to determine if the coolant in your engine meets these limits. If contamination has occurred clean and flush system with Restore [CC2610] to remove Oil, Fuel, Grease, and Silicate Gel.  Use Restore Plus [CC2638] to remove Rust, Corrosion, Scale, and Solder Bloom.
Monitor your Cooling System -
Check freeze point, glycol and additive levels with [CC2602A]
Check:Molybdate, Nitrate, Freezepoint, and pH with
ES Compeat OAT 4 Way Test Strips [CC8997]

* To maintain the protection provided by ES Compleat OAT, the proper level of inhibitor must be present. This can usually be achieved by topping off the cooling system with premixed ES Compleat OAT coolant. The user is responsible for ensuring proper additive levels and coolant pH through the use of test strips and the addition of new coolant if necessary. The recommended test interval is 300,000 miles, 6,000 hours, or 1 year. The test interval is a precautionary recommendation intended to prevent progressive, severe engine damage. For proper test strips for AOT coolant see Fleetguard part numbers CC8997 and CC2718
