Keeping Your Engine Cool In Huntington Beach, CA

The cooling system keeps CA motorists’s engines from overheating while they are driving around Huntington Beach, Stanton and Cypress. Its job is to move heat away from the engine. Let’s talk about the various components of the system and how they make this happen.

The radiator is the part most Huntington Beach car owners associate with the cooling system. Coolant flows through the radiator which has fine cooling fins that draw the heat out of the coolant and dissipate it into the air. To make sure there’s enough airflow over the radiator, a fan pulls air over the cooling fins even when the SUV is idling.

In some SUVs, the fan is powered by the serpentine belt. On others, an electric motor runs the fan. Electric fans turn on and off as needed. You may have heard the fan kick on shortly after you turn your SUV off. The sensor has determined that the engine needs a little help cooling down to a safe temperature.

Huntington Beach CA Radiator A hose connects the radiator to the water pump. The water pump pushes the water into the SUV engine block. Now the engine block and cylinder heads have passages for the coolant to pass through without getting into the oil or the combustion chamber. In the automotive community, these passages are referred to as the “water jacket”.

While the coolant is passing through the water jacket, it absorbs heat from the SUV engine on its way to the radiator for cooling. Between the engine and the radiator is a gatekeeper called the thermostat. The thermostat’s job is to regulate the temperature of the engine just like your home thermostat regulates the temperature in your Huntington Beach house. It gets your engine up to the correct operating temperature and then keeps it from overheating.

When you first start the engine, it’s very cold and needs to warm up. So the thermostat blocks the flow of coolant to the radiator. As the engine warms up, the thermostat starts to let coolant flow through the system.

The final component the team at Sully’s Auto Repair wants to point out is the overflow reservoir. This bottle is designed to hold some of the coolant. It’ll have a mark that indicates whether or not you have enough coolant. This is where you should add coolant if you just need to top it off.

Caution: never open the reservoir or the radiator cap when the car’s hot. The cooling system is pressurized and opening them while it’s hot can cause hot coolant and steam to escape resulting in serious burns.

Cooling system failure is the most common mechanical failure in vehicles around Huntington Beach, CA. At Sully’s Auto Repair, we can do a periodic inspection of the components for detrimental leaks, loose connections and weakening hoses.

Your auto maker has also specified a cooling system service interval. With a cooling system service at Sully’s Auto Repair in Huntington Beach, the old coolant is replaced with correct clean fluid that contains the additives required to prevent corrosion. The additives are depleted over time and you need fresh fluid for adequate protection. Your radiator pressure cap should be replaced at this service as well.

The most recognizable part of the coolant system to Buena Park car owners is the radiator. It is connected to the engine with hoses and is filled with coolant. The coolant draws heat off the engine and then passes into the radiator. Air passes through cooling fins to reduce the temperature of the coolant and then it’s back to the engine again.

There are several ways for the cooling system failure. Most common is with the coolant itself. Coolant is comprised of water and antifreeze. The proper ratio keeps the coolant from either boiling away or freezing. Understandably, either can lead to massive engine damage.

Another important coolant issue that is often overlooked by Huntington Beach drivers is the age of the coolant itself. Antifreeze has additives that protect the coolant system from corrosion. As these additives are depleted over time, they can’t protect the radiator and other parts from rust, scaling and corrosion. That old container of coolant gathering dust in your garage may still keep your engine cool, but it won’t protect it from corrosion.

If get a warning message to check the coolant or if the SUV temperature gauge is in the hot zone, your cooling system needs to be checked. It’s OK to add water or antifreeze yourself. But you need to be cautious. Remember four things:

  • First, you never want to open the radiator pressure cap. You could be severely burned.
  • Second, get to Sully’s Auto Repair in Huntington Beach immediately if your coolant is low. If that is not possible, follow the directions in your SUV owners manual – it will direct you to only make additions to the coolant overflow bottle.
  • Third, remember that you need a proper mixture of water and antifreeze. If you make an emergency addition to your cooling system, follow-up with your Sully’s Auto Repair service center where we can make necessary adjustments.
  • Fourth, not all cars use the same type of antifreeze. You need to check your SUV owners manual to make sure you use the right kind. Mixing antifreeze types or using the wrong kind of antifreeze may void the manufacturers warranty on your cooling system. Again, another reason to depend on your Sully’s Auto Repair service center in Huntington Beach to do things right.

Remember, your Huntington Beach service center has the equipment to change your coolant quickly and inexpensively.
