When it’s hot outside and you have places to go, you just want to stay cool and comfortable as you drive. You want to get into the sanctuary of your car’s passenger cabin, turn on some music and AC, and just chill. You can’t do that, however, unless the air conditioning system has a sufficient amount of refrigerant (coolant or cooling agent). For more information on this important substance as well as reputable vehicle AC repair, visit Valencia Auto Performance and Simply Smog in Santa Clarita, CA.
To understand why coolant is important, you need to know how the AC system works. It uses refrigerant (a gas) which is changed by the compressor into a liquid. That liquid is pressurized and forced through hoses until it reaches the condenser on the high pressure side of the system where it is cooled in a manner similar to the way a radiator works. Then the coolant moves through either an orifice tube or expansion valve to the evaporator core on the low pressure side of the system. (The specific construction of your AC system dictates whether you’ll find an expansion valve or orifice tube.) The refrigerant is now once again a gas. It absorbs heat from air passing through the evaporator fins. Cooled air goes through vents into the passenger area. The warmed refrigerant returns to the condenser to begin the cycle again.
Depending on the age of your vehicle and where you are in terms of system repair, you may hear reference to three kinds of refrigerant/coolant. They all serve the same function, but we’ll outline the differences below.
Although you may have wondered about refrigerant/coolant, don’t sweat finding a local shop. Valencia Auto Performance and Simply Smog is your cool reliable choice.
