The Guardian Turbo Timer is designed to keep engines running after they have worked under load to cool-down the engine, the default time on our system is five minutes. The reason why this is important to do is that it allows the internal temperature of the engine to be brought down gradually, so the turbine won’t burn the lubrication oil that would otherwise be trapped within the charger with the turbine rotating at high speed.
Guardian Turbo Timer is an automatic system that will start immediately after the key has been turned off.
