A Video is at the bottom of the page for a visual walk-through if needed.
If you have a 2009-2013 Toyota Corolla and the air conditioning stops blowing cold air it may need to be recharged.
This is a common problem with cars as they age with it being a simple fix to add more refrigerant to the cooling system.
I have a 2012 Toyota Corolla that needed charge so I wrote this post along with a video at the bottom of the page to help anyone who may need to charge the system.
Things Needed To Add Refrigerant on a 2009-2013 Toyota Corolla
- R134a Refrigerant bottle
- Fill Hose
The 2009-2013 Toyota Corolla uses R134a refrigerant. There are small low-cost bottles available to buy at automotive stores and online.
I bought R134a on Amazon to charge the system, but almost any automotive store should also have the refrigerant bottles.
If you have a refrigerant leak there is also Stop Leak mixed with R134a that may help.
For most, a simple R134a bottle will be all that is needed.
A recharge line will also be needed and is a low-cost item.
2009-2013 Toyota Corolla Refrigerant Fill Location
The refrigerant is added to the low pressure side of a vehicles cooling system.
It is located under the hood on the passenger side to the left of the engine.
A cap will be on the port that will screw off to access the fill location.
*It is important to fill the AC system slowly since overcharging the system will cause it to not work.
How To Add Refrigerant to a 2009-2013 Toyota Corolla
- Ready the bottle by attaching the hose to it.
- Attach the hose to the Low Pressure line Port.
- Start the car and power on the AC to high.
- Open the hose adapter letting refrigerant into the system.
- Check the air vent to see if it blows cold air.
- Stop once cold air blows out by closing the valve on the bottle adapter.
Summary
Recharging the air conditioning system on a 2009-2013 Toyota Corolla is easy to do for a handy DIY type of person.
Of course, if in doubt take it to a professional.
If the car has a slow leak using the Stop Leak with R134a can help to seal a system.
It is not usually necessary though, with standard R134a available in small cans all that is needed in most cases.
Keep in mind other things can cause an AC system to not blow cold air.
The air flow indicator on the filter should go DOWN. Otherwise Thank You for the informative video.
