Extended life coolant, or ELC, can simplify a fleet manager’s life by providing a longer service interval compared to conventional coolants.
When transitioning from conventional coolant to an ELC, you need to be aware of the conversion practices and ensure that you inspect and tighten the system as you go through the process. When it comes to the drain, flush and fill process, be aware that IAT coolants have the ability to mask leaks in the system due to silicates that build up over time. When you put in the ELC, it could scrub these blockages away and expose existing leaks in the system.
Once you’ve completed the drain, flush and fill with the new OAT coolant, it’s important to follow the recommended preventative maintenance requirements.
Visual inspections, testing the freeze point, checking the corrosion inhibitor level and topping off with the correct ELC is all imperative to keeping your coolant systems running soundly.
