AIR CONDITIONING SERVICE
The air conditioning unit in your vehicle operates similarly to a refrigerator. Your vehicle’s air conditioning unit is designed to move heat from the inside of your truck to outside of it.
Your vehicle’s air conditioning unit has six major components:
- The refrigerant carries heat. In modern trucks, refrigerant is a substance called R-134a. Older vehicle’s refrigerant is called r-12 freon, which is more expensive and difficult to find than R-134a.
- The compressor circulates and compresses refrigerants within the vehicle’s cooling system.
- Your vehicle’s condenser changes the refrigerant from gas to liquid and expels heat from the truck.
- The expansion valve (sometimes called the orifice tube) is a nozzle that simultaneously drops the pressure of the refrigerant liquid, meters its flow and atomizes it.
- Your vehicle’s evaporator transfers heat to the refrigerant from the air blown across it, cooling your truck.
- The receiver or dryer filters your vehicle’s refrigerant and oil, removing moisture and other contaminants from them.
WHEN YOU START YOUR VEHICLE’S AIR CONDITIONING SYSTEM,
the compressor works by putting the refrigerant under pressure, sending it to the condensing coils, which are generally in front of your vehicle’s radiator. The condenser expels hot air to outside the truck, cooling the air within the vehicle. When this happens, the refrigerant is cooled, and it changes from a gas to a liquid, which then passes through the expansion valve and to the evaporator.
Once the evaporator receives the liquid-state refrigerant, it loses pressure and cools the remaining liquid. The vehicle’s blower moves air across the evaporator and into the vehicle’s interior. If you keep your air conditioning unit in your vehicle turned on, the refrigerant goes through this cycle continuously.
it can turn your cool truck into a furnace during the summer months. Your vehicle’s air conditioning issue could be as simple as topping off refrigerant to replacing a valve. When your air conditioning unit is not working as it should, bring your vehicle to Last Chance Diesel, conveniently located in Ogden, Utah. One of our trained air conditioning specialists will inspect your truck’s air conditioner, all lines, the evaporator and the compressor for leaks and wear.
Radiator Service
If your vehicle overheats, you may need to have your radiator serviced or replaced.
An elevated temperature gauge is another sign that your radiator might be malfunctioning. Puddles of green, yellow or orange coolant under your truck could indicate that there is a radiator leak, which could be caused by corrosion. If you notice any of these signs that your radiator needs to be services or replaced, bring your vehicle to Last Chance Diesel Repair Shop. Our Ogden, professionals can fix leaks or replace your vehicle’s radiator so you can get back on the road worry-free.
