What is a cabin air filter? Is it:

A. A filter for your Minneapolis house?
B. A fresh, piney scent?
C. A filter for the passenger compartment of your car?

Clever you, it’s C.

A cabin air filter cleans the outside air before it comes into the passenger compartment. It filters out common Minneapolis air particles like dust, pollen, spores, bacteria, pollutants, exhaust gas, odors and even sparrows.

These high tech filters can block particles larger than 3 microns. By contrast, a grain of sand is about 200 microns.

Not all vehicles in Minneapolis have cabin air filters. They are fairly new on the scene. About forty percent of new vehicles sold in Minneapolis come with cabin air filters, but the number is growing every year.

Cabin air filters can make for a very nice driving environment. Your car can be a haven during our Minneapolis allergy season with very little dust and pollen getting into the cabin. However, the filter eventually gets clogged. When this happens, your heating and air conditioning flow can become restricted. The filter can even get kind of smelly.

Check your owner’s manual for recommended replacement intervals. Often, the owner’s manual forgets about the cabin air filter, so ask your service technician at Four Star Auto Service for a recommendation. It’s usually every year or 12,000 miles / 19,000 kilometers. Change it sooner if you drive in dusty conditions around the Minneapolis area, or if you start to notice an odor from your ventilation system.

So keep your cabin air filter clean. It may not help with your brother-in-law in the backseat, but it will make your driving experience around Minneapolis more enjoyable.

Come by Four Star Auto Service and we’ll take a look at your cabin air filter for you.

The cooling system keeps our engine from overheating while you are driving around Minneapolis Mn. Its job is to move heat away from the engine. Let’s talk about the various components of the system and how they work to accomplish this.

The radiator is the part most everyone associates 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 car is idling.

In some vehicles, 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 car off. The sensor has determined that the engine needs a little help cooling down to a safe temperature.

A hose connects the radiator to the water pump. The water pump pushes the water into the 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. These passages are referred to as the “water jacket”.

While the coolant is passing through the water jacket, it absorbs heat from the 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 of your house. It gets your engine up to the correct operating temperature and then keeps it from overheating.

When your 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 I want to talk about 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 Minneapolis Mn. Your Minneapolis Mn service center can do a periodic inspection of the components for leaks, loose connections and weakening hoses.

Your manufacturer has also specified a cooling system service interval. With a cooling system service, 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.
