Detailed Product Specifications

Havoline Extended Life Anti-Freeze/Coolant DEX-COOL is a single-phase, ethylene glycol type universal automotive engine coolant based on a Texaco's patented long life organic corrosion inhibitor system.

Havoline Extended Life Anti-Freeze/Coolant Pre-Mixed 50/50 DEX-COOL is a 50/50 mixture of Havoline Extended Life Anti-Freeze DEX-COOL with deionized water.

Havoline Extended Life Anti-Freeze/Coolant DEX-COOL is a universal engine coolant that incorporates patented organic acid corrosion inhibitor technology. This coolant meets both ASTM D 3306 for automotive service and ASTM D 4985 for heavy-duty diesel service. It is a nitrite-, nitrate-, phosphate-, silicate-, borate and amine-free formulation which uses Texaco’s 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. The low level of abrasive dissolved solids in Havoline Extended Life Anti-Freeze/Coolant DEX-COOL results in improved water pump seal life.

The life of a coolant in an automobile engine is limited by the corrosion protection ability of the corrosion inhibitors. The main corrosion inhibitors in Havoline Extended Life Anti-Freeze/Coolant DEX-COOL have been shown to remain above 95% of their original concentration after 150,000 miles in automobiles.

This allows much longer intervals between coolant changes without worrying about loss of corrosion protection. Used Havoline Extended Life Anti-Freeze/Coolant DEX-COOL was tested in laboratory controlled corrosion tests for new coolants after it had already been in service for more than 200,000 miles.

The used Havoline Extended Life Anti-Freeze/Coolant DEX-COOL passed the ASTM D 1384 requirements for glassware corrosion with results equivalent to new coolants and also passed the ASTM D 4340 Aluminum Hot Surface Test for new coolant. Havoline Extended Life Anti-Freeze/Coolant DEXCOOL represents the next generation of universal engine coolants.

This coolant is suitable for a five year or 150,000 miles service life in automotive applications. Note: These products are not to be used to protect the inside of potable water systems against freezing.

Havoline Extended Life Anti-Freeze/Coolant DEX-COOL is manufactured from ethylene glycol and a highly effective long term corrosion inhibitor package based on carboxylate technology. This inhibitor system eliminates the need for
silicates, phosphates, borates, nitrites, nitrates and amine additives traditionally used for this purpose. The replacement of these inhibitors is significant for water pump life because many of these conventional inhibitors have been shown to be abrasive to water pump seals. In comparison field tests with conventional coolants in taxi fleets, Havoline Extended Life Anti-Freeze / Coolant DEX-COOL significantly reduced the need to replace water pumps during the 100,000 mile test.

In addition to fleet tests, this product has also been tested by a major manufacturer of water pump seals, and has been found to be more compatible with the seals than any other coolant tested.
