Your air conditioning (AC) is blowing hotter air than a politician hoping for re-election! It’s so hard to roll down the windows, and sitting in a pool of stagnant sweat and grease-rich fumes under your thighs is a recipe for an uncomfortable, nauseating ride.
Where Do I Add Freon To My Car
Contrary to the belief that AC brings icy air into the cabin, an AC system heats the hot air less and creates a cooler air feel. It removes heat, not cold. This is accomplished by a refrigerant-based circulation system that includes a compressor and a condenser and absorbs heat. The most common cause of AC system overheating is a low coolant level.

Fortunately, this is also the easiest thing to fix. To keep you cool and cool in the summer heat,
Our information team is here to tell you what you need, what to do and how to do it.
A car’s AC system has seven main components. The system uses a closed design and circulates the coolant throughout. Here is the role of each piece of the puzzle:
Working on your car can be dangerous and messy, so this is exactly what you need to ensure you don’t die, become disabled or lose a finger.

Additionally, handling compressed air cans presents its own set of safety concerns. Never leave a pressure can in direct heat or on a hot engine block. In very rare cases, the box may heat up until the compressed air explodes.
Or if you don’t want to bother with a lot of parts and want everything you need to be well organized in one place, you can use the AC refill kit.
Organizing your tools and equipment so that everything you need for AC refilling is within easy reach will save you precious minutes waiting for your handy kid or four-legged helper to bring you sandpaper or a lighter. (
You also need a flat work surface, such as the floor of a garage, driveway, or street parking lot, to properly charge the AC. Check your local laws to make sure you’re not breaking any codes while on the road because we can’t shock your car.

Can I Recharge My Car’s Air Conditioner Myself? How To Guide
Coolant slowly drains from the vehicle’s AC system, but there is no current maintenance program. If you have one of the AC pressure gauges, use it to test the system while the AC is cooling.
A basic box of regular coolers costs less than $10. A can of socks and gauges costs about $40-$50.
Since you may not have access to the right tools or have a friend to turn off the key, we’ve rounded up our best tricks to make your life easier and leave less of a dent in your pocket. Air coming out of your car vents? isn’t it cold like before? The cooling system may be low on coolant.
Over time, small amounts of refrigerant leak through the lines, reducing air conditioning performance. The solution is simple – put more.

Refilling the air conditioner yourself is cheap and can be done in a few minutes. This is one of the quickest and easiest tasks to perform during car maintenance, but if not done correctly it can cause problems with the air conditioning system, so read each step carefully before proceeding. When you’re done, your air conditioner should be producing cool air, and the whole process should cost you about $25-$35 and 15 minutes of your time.
The conditioner consists of three main parts. Condenser, compressor and evaporator. The condenser and evaporator are two radiators connected in a circuit. The compressor is located between them on one side of the circuit. The system is sealed from the outside and filled with a working fluid, in this case r-134a. The compressor takes in low pressure, gaseous r-134a, compresses it (which creates heat) and then sends it to the condenser, where the heat is dissipated. After the condenser, the liquid refrigerant travels to the evaporator located inside the passenger compartment, where it is allowed to expand, removing heat and cooling the evaporator. The fan directs air over the evaporator and then out the air vents in your car.
Because the working fluid is very hot and very cold, it is important not to get moisture into the system, as ice formation in the compressor can damage it.

First, was your car built before 1994? If so, your vehicle uses R-12 and this guide is not for you. However, if you locate the engine and find a label indicating that the system has been converted for use with r-134a, go ahead.
Buy regular r-134a refrigerant from the bottom shelf. Don’t be fooled by the shiny cans with leaky seals and performance boosts. It’s just “snake oil” and can wreak havoc on your cooling system.
The distributor should also have a pressure gauge and a trigger. This is optional and necessary to do this safely and correctly. DO NOT BUY a diffuser/cooler combo.

Why Does My Car Ac Smell Bad?
4. Run from the filler port at the end of the hose to the cylindrical device attached to the engine – this is the compressor
No. Add half the can of r-134a as described in the following steps. If the compressor still does not turn on, take your vehicle to a mechanic.
7. Leave the engine and air conditioner running at full throttle until the full fill process is complete.
2. Locate the refrigerant charge port on the low pressure side of the system. It has a small plastic cover with an L printed on top. Unscrew this cover to expose the port.

On most vehicles, the low pressure side fill port is located on the left side of the engine compartment. This is often a small piece of metal tubing with two lengths of rubber tubing coming out of each end. Look at the back of the engine compartment called the firewall. The two pipes or hoses coming out of the firewall should be close together, one larger than the other. Follow the larger hose to find the low pressure fill port. The photos show the location of the fill port on two different late model engines.
DANGER! Do not touch anything that is unfamiliar to you. Almost everything in the engine bay moves and/or heats up. The high pressure (small) side pipes are very hot, do not touch them. It is best to keep the low pressure side hoses at room temperature.
4. While pulling the trigger and holding the sleeve up, firmly press the switch on the fill port.
5. Release the outer connector sleeve and then the connector itself. It must be placed in place at the fill port.

Pulling the trigger maintains a steady flow of coolant from the hose, cleaning it of outside air and moisture and keeping them out of the air conditioning system.
Refer to the chart supplied with the distributor to determine the minimum and maximum allowable pressure readings for the current outside air temperature. This is your target pressure range. Some gauges have an adjustable “V” to mark the allowable pressure range. Position yourself now.
1. Squeeze the trigger for 5-10 seconds, slowly invert and shake the can. NEVER CONTOUR DOWN.
3. Read the pressure reading on the manometer again. Measure the pressure only when the compressor is on. If the pressure is still too low, continue adding coolant as described above.
