Coolant Flushes


At one point, we have all been told we need to do a coolant flush. But how do they know your vehicle
needs one? The first method is simply following manufacturers guidelines. Depending on your vehicle,
the manufacturer will recommend that the coolant be flushed after so many kilometers. The second
method is a visual check. Over time, the coolant will become dark and murky, indicating it is building up
debris. The last method is a pH test. The technician will use test strips to measure acidity of the
coolant. If it reads below 7, it is time for a flush.
But why do you need one? Over time, the coolant will start to break down and become corrosive. At
this point, it will begin to wear holes in the cooling system components. The by-products of corrosion
damage, rust, and scale will begin to clog the passageways through the radiator and restricting flow. If it
gets bad enough, your vehicle can start to have overheated engine and become damaged. The coolant
flush will remove any rust, sludge and debris in the radiator and will clean out blocked water channels
that cause overheating. In the long term, performing coolant flushes with extend the life of the hoses,
water pump, heater core, thermostat, radiator, intake and head gaskets reducing maintenance and
repairs to your vehicle.
