Heat and Your Truck

Engine Coolant!!!

Approximately 7 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 damage the emission components such as the exhaust gas recirculation or EGR.

The benefit of using ELC is the fact that you can improve the engine’s heat transfer rate by 12 to 13 percent over conventional anti-freeze

During the pre-post trip inspection driver should:

  • Make sure that the coolant level is within range of the marking on the side of the coolant reservoir.
  • If the coolant level is low add coolant to the proper levels. ELC coolant should be a red/orange color and should be free of dirt, debris, rust and other contaminants. Do NOT mix ELC with mixed conventional antifreeze!
  • If when operating a CMV a dash light comes on with an overheat warning immediately pull the unit into a safe parking place. Operating the unit in an overheat situation can severely damage the engine.
