Frequently asked questions
How often should coolant be flushed on a fleet diesel?
Extended-life coolant runs long, but severe service and additive depletion shorten the interval. We test the coolant and set a schedule so it protects the engine.
Can you find an intermittent overheating cause?
Yes. We pressure test, check the fan clutch and thermostat, and test for combustion gases in the coolant to isolate hard to find causes.
