What should car AC pressures be?

The low-side should be near 30 PSI at 90 degrees Fahrenheit or less. Pressure that is too much lower or higher shows there is a problem. On a properly working system, high-side pressure will be about twice the ambient temperature, plus 50 PSI.

What refrigerant does Toyota use?

However, you need to know beforehand what type of Freon your exact Toyota model takes. Vehicles manufactured before 1984 take R-12 Freon, while post-1984 vehicles take R-134a. Both kits are widely available and easy to buy at automotive retailers.

What RPM should AC pressure be checked at?

Once you attach your gauges and start your engine, keep RPMs steady at around 1,200 to 1,500 RPM. Keep in mind that AC pressures and center duct temperatures are directly related to ambient temps and relative humidity. If your readings are outside the typical pressure/temperature range, see below.

How much freon does a 2008 Toyota Tacoma hold?

The prescribed 'refrigerant charge volume' spec is "570 to 630 g (20.10 to 22.22 oz.)".

Can you mix R134a with R-1234yf?

yes R1234yf Freon gas can be replaced by R134a; the newer systems were designed with this in mind so no, there will be no damage to the compressor but some time in the future doing so may become illegal. >>

What pressure should R134a run at?

For normal running pressures in the R134a system, at the lowest temperature, the coil should run at 22 pounds per square inch that is 45-20, 25 degrees Fahrenheit. While at the highest temperature it should be 57 pounds per square inches that is 60-20,40 degrees Fahrenheit.

What causes high AC pressure?

Higher than normal air pressure is usually a consequence of two situations. One, your AC system might be facing limited or no airflow through the condenser. This, in turn, might be a consequence of bad condenser fan motor. ... Second, the other reason for a high-pressure reading can be an overcharged system.

What causes high AC pressure high?

High pressure occurs when the needle valve gets partially stuck open and goes directly into the compressor's crankcase. This causes both high low-side pressures and low high-side pressures. You should closely monitor whether or not the oil return line is above or below the ambient surrounding temperature.
