WHAT IS ANTIFREEZE/COOLANT? Inhibitors + (4 -6%) Inhibitors Protect Metals From Rust And Corrosion Glycol -(50%) Glycol Provides Boil-Over And Freeze Point Protection Water - (50%) Water Transfers Heat
TESTING COOLANT • 1) Color • 2) Clarity • 3) Odor • 4) Freeze Point • 5) Chemical Protection CHEMISTRY THAT DRIVES COMMERCE
TESTING COOLANT • 1) Color – indicates technology or mixing – whatever the color of the coolant is (red, pink, yellow, green, gold), it should have a fluorescent color. It should not be brown.. • 2) Clarity – indicates oil, fuel, corrosion • 3) Odor – indicates high pH – ammonia state above 11.0 destroys soft metals – below 7 indicates acidic • 4) Freeze Point – indicates dilution -12 to -65 Fahrenheit acceptable 60/40 – 40/60 mix of glycol /water • 5) Chemical Protection – indicates adequate protection – dilution – use test strip – OAT use pass / fail. If it fails add converter/extender as per chart – ½ gallon to 15 gallon system. If Fully Formulated – uses NITRITE test strip & add SCA CHEMISTRY THAT DRIVES COMMERCE
6 Antifreeze / Glycol Testing (Freeze point) Test Strips DO NOT USE ! • Not accurate with Red Coolants • Small scale • Expire Hydrometers • Not very Refractometer (Analog) accurate • Very Accurate • Must be cleaned • Will Test EG / PG / Specific gravity after every use • Readings will be off on some newer coolants CHEMISTRY THAT DRIVES COMMERCE
WHEN SHOULD I I TEST THE COOLANT? Every 20 – 25,000 miles Or Every 3 – 4 months Or Every 600 – 800 hours CHEMISTRY THAT DRIVES COMMERCE

Flux Problems: Some aluminum radiators are contaminated on the inside with brazing flux. The flux residue can bind to the silicate in conventional coolant causing it to drop out and plug the system. Since the silicate was the primary protection for aluminum, the aluminum radiator is left unprotected against corrosion, which is accelerated by the flux. A flush and fill removes the flux and the system ready to last a life time. Factory fill with ELC eliminates the silicate issues since most ELC isn’t formulated with any. Unfortunately the flux is still present and may reduce the effectiveness or longevity of the coolant. . Nitrite has been shown to attack and corrode the aluminum in these high flow cooling systems. This is why some engine manufacturers are requiring the use of Nitrite free coolant. CHEMISTRY THAT DRIVES COMMERCE
Why Nitrite Free: Some aluminum radiators are formed with “dimpled” tubes to improve heat dissipation and allow the use of smaller radiators. Nitrite has been shown to attack and corrode the aluminum in these high flow cooling systems. This is why some engine manufacturers are requiring the use of Nitrite free coolant. Unfortunately, Nitrite has been one of the best ways to protect wet sleeve liners against cavitation erosion. This is why some engine manufacturers are still recommending Nitrite containing ELC - (NOAT ) formulations. CHEMISTRY THAT DRIVES COMMERCE
