ACDelco DEX-COOL ANTIFREEZE/COOLANT is recommended for use in the cooling systems of all types of automotive engines.
This product meets ASTM D 3306 for automotive service and ASTM D 4985 for heavy duty diesel service.
Dex-Cool is a nitrite, nitrate, phosphate, silicate, borate and amine-free formulation which uses a patented carboxylate technology to provide maximum protection of the six basic metal alloys found in most heat transfer systems.
Since the coolant contains no phosphates or silicates, hard water deposits in the cooling system are almost eliminated.
Dex-Cool antifreeze/coolant is manufactured from ethylene glycol coolant with hybrid organic corrosion inhibitors (HOAT) and is a highly effective, long-term corrosion inhibitor package based on carboxylate technology.
Features and Benefits:
- Five-year/150,000-mile service interval.
- Is more compatible with water pump seals than conventional coolant.
- Offers superior protection in high operating temperatures.
- Minimizes the formation of abrasive dissolved solids.
- Provides effective, long-term corrosion protection for aluminum, brass, cast iron, steel, solder and copper.
- No silicate dropout or gel formation during use or storage.
- Outstanding hot surface aluminum protection.
CAUTION: Mixing conventional green coolant with DEX-COOL will degrade the service interval from 5yrs./150,000 miles to 2yrs./30,000 miles (50,000 km) if left in the contaminated condition. If contamination occurs, the cooling system must be flushed twice immediately and re-filled with a 50/50 mixture of DEX-COOL and clean water in order to preserve the enhanced properties and extended service interval of DEX-COOL.
