WHAT IS A COOLING SYSTEM?
The cooling system in your vehicle uses water circulated through a pump and a radiator to cool moving parts. Some older cars cool the engine by air, rather than water, but this is generally less efficient. A radiator is positioned on the outside of a fan, containing a water pump. A thermostat measures the temperature of the water and two sets of hoses channel the water through the vehicle via transmission cooling lines.
WHAT IS A COOLING SYSTEM SERVICE?
Many know that the radiator, a part of your vehicle’s cooling system, keeps your engine from overheating. However, a little known fact is that the radiator also adjusts your fuel mixture and timing. The modern cooling system’s sensors enable your vehicle’s efficiency. In order to keep your vehicle running smoothly, you must keep the cooling system working smoothly, as well. This is why we recommend flushing your cooling system at least once every two years by a trained technician with the correct equipment.
That is where we come in at 7 to 7 Auto Services. Our Cooling System Power Flush replenishes coolant and removes contaminates, by using a highly-pressurized system to reach the engine, the radiator, the heater core, and even through the 25 and 5micron filters in opposite directs at different intervals. We also apply antifreeze or water, depending on the needs of your vehicle, to ensure a functional cooling system. The choice between water and antifreeze depends on a few factors. Water more easily absorbs heat from the engine than antifreeze. However, water can freeze and become corrosive to all metal parts, whereas antifreeze protects your radiator from corrosion and lubricates all moving parts in the cooling system. A balance between water, on one hand, and antifreeze on the other has to be struck, in order to prevent friction and corrosion but also to prevent freezing within the cooling system. The perfect balance of 50/50 water:antifreeze is indicated by a coolant temperature of 35 degrees.
Additionally, we keep the acidity levels of the cooling system at a safe level of 10.5, by testing the pH as we add antifreeze and/ water and adding a special concentrate to prevent acidification. Acidification of the water-antifreeze mixture means that the fluids become so acidic that they eat away at your vehicle’s radiator, heater core, water pump, head gaskets, freeze plugs, and heater hoses. This is how we ensure your radiator will function properly, after we have full flushed and cleaned the system – by perfectly calibrating the fluid and pH levels for your vehicle’s cooling system. To top it off, we thoroughly check for leaks, clean the recovery bottle, and test the radiator cap for proper pressure retention.
Once we have conducted our Cooling System Power Flush for your vehicle, the radiator will stay in a safe pH range of 9.8-10.5 for roughly two years or 30,000 miles. Servicing your cooling system is a good investment, indeed.
