Why do some coolants turn brown in color ?
In some automobiles where coolants are not used for long duration of time there is rust formation in the cooling systems. When coolants are used they start removing the rust accumulated over the period of time which has no where to escape, so it starts floating & circulating in the cooling system and blocks small passages in the system. Thus causing the car to overheat. So it is recommended that whenever you drain the radiator without fail flush the cooling system with a good quality radiator flush & then continue with a fresh fill of Genuine Quality Mobile Coolz Coolants.
