Cooling System Service
Summary of this article:
Neglect of the cooling system is the #1 cause of expensive engine repairs.
The cooling system consists of the Radiator, Water Pump, Thermostat, and Coolant/Water Mixture.
Coolant is a mixture of 50% of the RIGHT coolant/anti-freeze and 50% water.
Improper balance of water and coolant causes corrosion and serious problems that you cannot see.
Coolant breaks down in its protective qualities with time and mileage.
The cooling system must be serviced periodically to make sure the cooling system is doing as it is designed.
The service intervals depend on your car, mileage and the manufacturer’s recommendations.
Many auto repair companies only do a drain and refill as their coolant system service.
Drain and fill leaves up to 60% of the old ineffective fluid inside.
To properly service the cooling system you must use equipment to completely flush out the old fluids and replace it with all new fluids.
Camarillo Car Care always recommends the proper cooling system flush and refill method.
Camarillo Car Care is a strong advocate of saving your money and giving you many added benefits through proper maintenance on your cars.
From our experience, the number one cause of major engine failure is cooling system problems due to neglect of the cooling system. We see some very expensive engine repairs due to this neglect – several $1,000’s is very common. Obviously, this is a very important topic for our customers. Remember, our goal is to help you prevent major breakdowns and to save you money. We do this by encouraging affordable maintenance when your car needs it.
First, lets understand how the cooling system works
The cooling system consists of a radiator, a water pump, a thermostat and hoses. A mixture of water and coolant/anti-freeze flows through the engine, water pump, thermostat and radiator. The goal is to dissipate and remove the heat off the engine. The fluids constantly flow through the system through the radiator. The radiator uses air from the car’s motion and radiator fan to aid in the cooling of the fluids.
This system sends lower temperature fluid back into the engine constantly. This keeps your engine from overheating. Overheating causes major engine damage and is very expensive.
Understanding water and coolant
Water is a great coolant for the engine. It even does a better job than the coolant/anti-freeze itself. In fact if you wanted to cool an engine, water alone is the best method. However, there is one problem with only water: it corrodes the internal parts of the engine. Corrosion damages many important components in the cooling system that can restrict cooling. So, we add coolant to the water to help protect the cooling system from corrosion. The coolant is also an anti-freeze formula that helps to prevent the water from freezing in your engine.

Rust, scale and sludge can plug cooling system fins, preventing proper circulation of coolant.

Severe corrosion can occur when additives that protect the cooling system have been depleted.
To strike the right balance of water and coolant we mix 50% water and coolant. The coolant is a blend of chemicals that inhibits rust, while the water is for cooling. In the old days, we only had one type of coolant. Each technician or auto repair shop had their favorite brand, but there was really only one type. Today, we stock six different types of coolants. This is because some car manufacturers require a specific type. Therefore, you would need to mix the right coolant and water, not just any coolant
Cooling systems are becoming more complex with later model cars. We are becoming chemists to a degree. We have to ensure that right pH, percentage of coolant additives to water ratios, and measure the presence of stray voltage (electrolysis) in the fluids. Certainly, times were more simple and easier to troubleshoot and maintain. Today, though, we must be aware of a wide variety of technologies related to cooling.
Suggested cooling system service intervals
We recommend and perform a visual inspection of the cooling system at each oil change service. This visual inspection consists of looking at the fluid levels and looking at the consistency of the fluid, then topping the fluid levels if needed. That is all that is needed between cooling system services.
Thorough Cooling System Inspections Intervals
Periodically, it is important to do more than just a fluid top off. A more thorough inspection is needed. We do this periodically depending on how long and how many miles you have driven since your last cooling system service. We also factor in what your car manufacturer recommends, and the current condition of the cooling system. Additionally, we encourage more frequent thorough inspections after your car has reached 50,000 miles.
