What kind of Freon does a 2012 Toyota Corolla take?

The 2012 Toyota Corolla uses R-134a refrigerant.


In this model year, the air conditioning system relies on the standard R-134a refrigerant (not the newer R-1234yf). If you’re planning maintenance, use the correct refrigerant and oil, and recharge by weight following Toyota’s specifications.


Refrigerant specifications for the 2012 Corolla


Key information to guide service and recharging:



  • Refrigerant type: R-134a (also known as HFC-134a)

  • Lubricant: PAG-46 oil is commonly used with R-134a in Toyota A/C systems

  • System capacity: roughly 20–22 ounces of refrigerant, depending on equipment; check the under-hood label or owner's manual for the exact figure

  • Compatibility: do not use R-12 or R-1234yf in this system; mixing refrigerants can damage the compressor and is hazardous

  • Charging method: weigh the refrigerant when charging and use proper gauges and fittings; when in doubt, have a certified technician do the service


Concluding: These factors guide the correct refrigerant choice and amount for the 2012 Corolla; incorrect charging can reduce cooling efficiency and risk damage.


Compatibility and regulatory notes


R-134a was the standard refrigerant for this Corolla year. Some newer Toyota models and regions are moving toward R-1234yf due to environmental rules, but retrofitting older cars to the newer refrigerant is not common and should be evaluated by a professional. Always follow local regulations and manufacturer specifications when servicing the A/C system.


Charging tips and best practices


Before charging, be aware of best practices to ensure safe and effective service:



  • Use a professional-grade R-134a refrigerant with the correct PAG-46 oil

  • Charge by weight rather than by feel; typical capacity is around 20–22 oz, but verify for your vehicle

  • Check for leaks first; refrigerant loss usually indicates a leak that should be repaired

  • Consider having the system evacuated and recharged if the compressor's oil or seals have degraded


Concluding: Following these practices helps maintain cooling performance and protects the A/C system from premature failure.


Summary


The 2012 Toyota Corolla’s A/C system runs on R-134a refrigerant, with PAG-46 oil, and an approximate charge of 20–22 oz. Do not mix with R-12 or R-1234yf, and have the system serviced by a qualified technician to ensure proper weight-based charging and leak checks.

What gas does a 2012 Toyota Corolla take?


In summary, it is best to stick to the recommended 87 octane fuel for your Toyota. This is the peak efficiency level for your vehicle.



Does my car use R-134a or R-1234yf?


Finding out which refrigerant your vehicle uses is easy with the help of A/C Pro®. The first place to look for this information is under the hood. Pop the hood and look for a label, which is usually white or bright yellow. On this it will either say “R-134a” or “R-1234yf,” and it may even say what the capacity is.



What kind of coolant does a 2012 Toyota Corolla take?


The recommended coolant for a 2012 Toyota Corolla is a yellow, long-life, phosphated HOAT (Hybrid Organic Acid Technology) antifreeze/coolant, such as the Zerex Asian Vehicle Red 50/50 or Prestone Universal Yellow compatible products. You can also use the specific Toyota Super Long Life Coolant (SLLC), which is pink. It is crucial to avoid mixing different types of coolant, especially green conventional coolant, as this can cause corrosion and damage to the system.
 
Coolant types for your 2012 Corolla

  • Recommended: Use a yellow, long-life coolant formulated for Asian vehicles, as it meets Toyota's requirements for a phosphated HOAT (Hybrid Organic Acid Technology). 
  • Toyota Genuine: You can use Toyota Genuine Super Long Life Coolant (SLLC), which is pink and pre-mixed. 
  • Alternative options: Some compatible products include Zerex Asian Vehicle Red or Valvoline Zerex Asian Vehicle Red coolant, which is specifically designed for Asian vehicles like Toyota. 
  • Avoid: Do not mix different types of coolant, particularly the old green conventional coolant, with the new yellow or pink coolant. 

Important considerations
  • Check your owner's manual: The owner's manual is the best source for information on the correct coolant type and maintenance intervals for your specific vehicle. 
  • Do not mix coolants: Mixing different coolant types can lead to corrosion and clog your radiator. 
  • Use a 50/50 mix: Ensure the coolant is a 50/50 mix of coolant and distilled water unless it is a pre-mixed formula. 
  • When in doubt, consult a professional: If you are unsure which coolant to use, consult a Toyota-trained technician or dealership to ensure the correct product is used. 



What coolant does a Toyota Corolla use?


A Toyota Corolla uses a pink or red, HOAT (Hybrid Organic Acid Technology) coolant, with the original manufacturer using Toyota Super Long Life Coolant. You can use either pre-mixed or concentrate versions, but if using concentrate, you must dilute it with distilled water. It is best to use a coolant specifically formulated for Asian vehicles or the genuine Toyota brand to ensure proper long-term protection, notes Toyota Parts Center Online and Reddit users.
 
Key takeaways for choosing coolant

  • Use a HOAT coolant: The specific technology for many Asian vehicles, including modern Corollas, is HOAT. Look for coolants labeled as "Asian" or "HOAT". 
  • Color is a good indicator: The correct coolant is often pink or red. 
  • Check your owner's manual: Always consult your vehicle's owner's manual to confirm the specific coolant type and any other requirements. 
  • Use "Super Long Life" or equivalent: Toyota recommends its "Super Long Life" coolant for optimal protection. You can find third-party brands marketed for Asian vehicles that are compatible. 
  • Use the right mix: If you buy a concentrate, you must dilute it with distilled water to the correct ratio, typically 50/50, for your climate. If you buy pre-mixed, it is ready to use out of the bottle.
