Safety Warning
DIY auto repair can cause serious injury, fire, or vehicle damage. These guides are for informational purposes only. Always follow OEM torque specs, wear PPE, and consult a certified mechanic if you are unsure. You are solely responsible for your safety.
Refrigerant R1234YF, Environmental Information
- R1234yf is a fluorocarbon and is colorless.
- R1234yf has a shorter atmospheric life span as R12 refrigerant and R134a and has a lower global warming effect (a lower global warming potential).
- R1234yf does not damage the ozone layer. The ozone depletion potential is zero (the same as R134a).
- The global warming potential of R1234yf (Global Warming Potential = GWP) is approximately 4 (the GWP of carbon dioxide = 1).
- The global warming effect of R1234yf is "350" times less than that of refrigerant R134a (global warming potential (GWP) of R134a is approximately 1400).
The global warming effect of substances is calculated through different processes by there effect in a time frame of 100 years, for this reason there are different values (for example on R134a a GWP between 1300 and 1450).
To make the influence of the greenhouse grasses on the Earth's atmosphere comparable a conversion takes place with the carbon dioxide equivalent. The refrigerant R1234yf has a global warming potential (GWP) of 4, for this reason 1 kg (2.2 lbs) of refrigerant R1234yf has approximately the same influence on the atmosphere as 4 kg (8.82 lbs) carbon dioxide ("CO2 ").

When to See a Mechanic
Stop DIY work and contact a certified mechanic immediately if any of the following apply:
- • You smell fuel, burning insulation, or see smoke.
- • Brakes feel soft, pull hard to one side, or make grinding noises.
- • The engine overheats, stalls repeatedly, or misfires under load.
- • You are missing required tools, torque specs, or safe lifting equipment.
- • You are not confident in the next step or safety outcome.
