Kocur Krew Automotive Automotive Tips: Air Blend Box Gladwin drivers push a few buttons or turn some knobs, and voila, they have toasty air blowing on their feet or cool air chilling their face. How does all that happen? Well, it’s all thanks to the air blend box. This box lives behind your dash and delivers just the right temperature of air right where you want it. Let’s break it down. First there is the blower fan that circulates the air through the heating/air conditioning system. The fan can blow at different speeds, depending on how much hot or cold air is required to be comfortable. The blend box can either deliver fresh air from outside, or recirculate air from inside the cabin. Gladwin motorists often choose to recirculate air when first starting the vehicle until it starts to either cool down or warm up. The next thing the blend box does is convey airflow over the heater core to warm the air, or over the air conditioner evaporator core to chill it – or a blend of hot and cold to get it just right. From there the blend box can direct the air out into the passenger compartment through the floor vents, the panel vents, the defroster, or a combination. All of this allows Gladwin car owners to customize the climate just the way the like it. Some vehicles have different climate control zones, like one for the driver and one for the passenger – or even more zones for the back seat. Additional blend boxes are used for this. Climate controls could be manually adjusted or computer controlled depending on your vehicle. The blower motor and all of the little actuator motors that open and close the various blend doors can fail and need to be replaced. Most new vehicles come with a cabin air filter. This filter cleans the air before it gets into the blend box. If you neglect changing the cabin air filter, it can get clogged, smelly, and even allow mildew and other microorganisms to build up in the blend box. Kocur Krew Automotive in Gladwin can perform a heating/air conditioning system cleaning service that will clean and disinfect the system, restoring a fresh clean scent. If you are not getting enough hot or cold air, Kocur Krew Automotive can review your system, diagnose the cause and set things right. And don’t forget to replace the cabin air filter on schedule. Moreover, if you live and drive in dusty Gladwin conditions or where there is a lot of pollen or other pollutants, you may need to replace your cabin air filter more frequently.

Smart Car Care for Gladwin Drivers: Radiator Fans
Gladwin drivers who are old enough have probably heard the term “fan belt”. Back in the day the radiator fan in your vehicle was turned by a belt driven by the engine. There are still belt driven fans – although most are now driven by the serpentine belt. But most Gladwin motorists now have electric fans that transfer fresh air across the radiator to cool it.
As coolant/antifreeze circulates in the cooling system it captures heat from the engine and flows into the radiator. Air cools the radiator and the coolant in it before it brings it back into the engine to pick up some more heat. Now your engine has an ideal temperature range in which it is most efficient: it shouldn’t be too hot or too cool. The electric radiator fans help maintain the ideal temperature.
A switch mounted in a cooling system passage checks the temperature of the coolant. If the coolant is at the low end of the range, the switch turns off the fan motor. When the coolant rises to a certain temperature, the switch turns on the fan. When you are running the air conditioning, the radiator fan will likely be turned on as well to help reduce the extra engine heat created by the load placed on it by the air conditioner.
A lot of Gladwin car owners’ vehicles will actually have two radiator fans. One or both or neither may be running at any given time depending on the conditions. When you are cruising at Midland highway speeds, the air rushing over the radiator and around the engine will help control the heat. By contrast, stop and go driving around Gladwin doesn’t generate much natural air flow so the radiator fans will be working hard.
Some Gladwin drivers may observe the sound of the radiator fan running after turning the vehicle off. This keeps the engine from heating excessively after it has been run and shut off.
Now the radiator fan motors and the switch are important wear items that will eventually fail. If your temperature light comes on while driving, you have a cooling system problem. Your friendly Kocur Krew Automotive service professional can check your entire cooling system, including the radiator fans, to determine what is causing the indicator light. Of course, servicing the cooling system as recommended will help extend the life of all the components. Ask your Kocur Krew Automotive technician if you are due for a cooling system service.
