WHAT IS A COOLING SYSTEM SERVICE?
Your radiator protects your engine from overheating. It also plays another
important role. In today's computer controlled engines, a radiator coolant
temperature sensor actually tells your car's computer and other sensors how to
adjust your fuel mixture and timing. So, the efficiency of your radiator
directly effects the efficiency of your engine.
That's why we recommend flushing your cooling system at least once every two
years. More importantly, we recommend having this service performed by a
knowledgeable repair shop with the right equipment.
Our Cooling System Power Flush continuously forces coolant under pressure
through the engine, radiator and heater core in both directions at different
times. Simultaneously, it forces the coolant through 25 and 5micron filters to
While the coolant is circulating, we add water or antifreeze, whichever is
needed. The molecules in water are spaced far apart, so water easily absorbs
heat from the engine, but water can freeze and corrode metal. The molecules in
antifreeze are packed tightly together, so antifreeze does not absorb heat
from the engine as efficiently as water, but its ethylene glycol silicone base
keeps the water from freezing, protects your radiator from corrosion and
lubricates the moving parts in your cooling system. When our coolant
temperature reading indicates 35 degrees throughout the system, we know that
we have achieved the correct 50/50 balance of water and antifreeze.
We also add a special concentrate to achieve the correct pH level of 10.5
throughout the cooling system. Without this, the 7.0 7.2 pH of water would
combine with the 10.5 pH of antifreeze to create an 8.75 pH mixture so acidic
that the resulting electrochemical degradation would deteriorate your
radiator, heater core, water pump, head gaskets, freeze plugs, radiator and
Finally, we pressure test your cooling system for leaks, clean the recovery
bottle and test the radiator cap to be sure that it holds the proper pressure.
Once your cooling system service is completed, the radiator coolant should
stay in the safe pH range of between 9.8 and 10.5 for about 2 years or 30,000
