It is the time of year when our attention turns to Holiday travel and the impending cold weather of winter. One of the items often overlooked on our vehicles is the coolant. Coolant (antifreeze) is normally a mixture of water and glycol, that when mixed in the correct ratio prevents water from freezing to temperatures of -45 degrees or colder. There are also additives in the coolant that prevent corrosion and lubricates seals inside the engine. Over time this coolant mixture breaks down and needs to be replaced/flushed.
During the Coolant flush process a chemical is added to the coolant that helps to dislodge deposits so that the flushing process will remove them from the system. The machine then pumps in new coolant forcing all of the old coolant out. The old coolant is collected and sent out to be recycled, so everything is disposed of in a responsible manner.
The radiator cap is also tested; however, for my money I would recommend replacing it every time the coolant is flushed, we recommend every 3 years or 36,000 miles after the initial flush. The radiator cap holds a constant pressure on the cooling system, this helps to prevent the cooling system from overheating.
You may also want to consider having the thermostat replaced at the same time. The thermostat regulates the temperature of the engine. A thermal wax valve opens and closes a door that allows the coolant to pass from the engine to the radiator, where the coolant is cooled. Recommended replacement of the Thermostat is 3 years or 36,000 miles whichever comes first. Remember our recommendations are designed to prevent you and your vehicle from being stranded on the side of the road.
The cooling system consists of many parts and neglecting the cooling system can lead to more expensive repairs and additional parts failures. Bad coolant can cause damage to the radiator, water pump, thermostat, hoses, radiator cap, engine block etc. So let’s prevent problems by maintaining the cooling system on your car
