Why Do I Need a Radiator Flush?
A radiator flush will clean out any of this debris, scale, rust or other contaminant that has built up over time. Built up contaminant over time can cause overheating issues due to blockages. Overheating can also lead to more serious problems in the future.
Another reason is that if you have a leaky cooling system. This may be caused by topping up your system with water and saturating your coolant. Mixing your coolant with water can lead to rust in your cooling system, and an indication of this may be that an orange or brown colour can be found on the radiator cap, or in the overflow bottles.
