Approximately 5 years ago the OEM truck manufactures introduced extended life coolant (ELC) into the industry. With each EPA change the operating temperature of the engine has increased 10 to 15 degrees. It is estimated that 50% of all engine failures are associated with an overheat condition of the engine.
With today’s emission systems, an engine running low on coolant runs the risk of damaging the emission components such as the exhaust gas recirculation (EGR). Using ELC can improve the engine’s heat transfer rate by 12-13% over conventional anti-freeze.
During the pre-trip inspection drivers should:
- Make sure that the coolant level is within range of the marking on the side of the coolant reservoir.
- ELC coolant should be a red/orange color and should be free of dirt, debris, rust and other contaminants. Do NOT mix ELC with conventional anti-freeze!
- If the overheat dash light comes on immediately pull the unit into a safe parking place. Operating the unit in an overheat situation can severely damage the engine. Call for assistance.
