What AC coolant does my car need?
In most cars that are on the road today, R134a refrigerant makes the A/C system blow cold on hot days. Selected for its low flammability and safety, as well as because it’s kinder to the environment, almost every car built since 1994 is equipped with R134 refrigerant.
What happens if you overcharge AC in car?
If the AC system is overcharged, the change from liquid to gas cannot happen, so the compressor starts producing liquid coolant instead of gas. It now has to work extremely hard to pump the excess coolant through the lines. The result is a noisy or broken compressor.
What color is the high side of an AC system?
Blue represents the low pressure side of the air conditioning system, and red represents the high pressure side. The low side service port is usually located between the AC compressor and evaporator.
What happens if you charge AC on high side?
High loads will make sure that the TXV metering device is fully open and delivering the maximum amount of refrigerant to the evaporator. At these higher evaporator heat loads, the receiver will be at its lowest level.
What kind of refrigerant does a Toyota Camry use?
It’s recommended that you follow Step 3 before having the compressor checked. The Toyota Camry uses R134a refrigerant as part of its cooling process. As the refrigerant heats and cools, it maintains a certain amount of pressure within the A/C system.
Where is the a / C compressor on a Toyota Camry?
The compressor is below the large belt. Although highly unlikely, it is possible for the A/C compressor to fail from general wear and tear. It’s very hard to diagnose this yourself since most other compressor problems are internal. It’s recommended that you follow Step 3 before having the compressor checked.
Why is my a / C not working in my Toyota Camry?
If your A/C fails to cool and doesn’t have an electrical problem, then this is the most likely cause of the issue. While it is possible to recharge the R134a pressure yourself, it’s not recommended. To do it properly would require special equipment such as a set of manifold gauges, a vacuum pump, and a canister of R134a.
What should the pressure be on a Toyota air conditioner?
If your Toyota’s air conditioning refrigerant recharge kit is equipped with high- and low-pressure gauges, you can use them to help identify when your vehicle’s refrigerant level is adequately pressurized. The low-pressure gauge should read between 25 and 40 psi (pounds per square inch).
