where do you add freon to a 1998 Toyota Avalon. Where is it located ? thats actually something u have to take to a repair shop to do. make sure the repair shop services the ac for ur car. depending where you go it can be a bit costly depending on the size of each of them.
The freon capacity for a 1995 Toyota Avalon is approximately 2.5 pounds (or about 40 ounces) of R-134a refrigerant. It's important to ensure that the system is properly evacuated and recharged to the correct specifications for optimal performance. Always refer to the vehicle's service manual or a professional technician for accurate information.
When you are going to add Freon to a Toyota Camry, you need to know which type to add. You will need to put the Freon recharging coupler to the recharging kit, and get the engine to operating temperature. When the engine is at operating temperature put the air conditioning on the lowest setting and recharge the Freon with the windows of the car rolled down.
R-134a
for a 99 it should be the new type AND there should be a sticker up on the inside of your hood stating the specific type in your system now.
Connect a freon gauge and the freon can to the low side ac port. With the ac running on high and the engine running, open the freon. Let it flow until the gauge shows that the system is full.
connect a Freon gauge and Freon tank to the low side ac port. After starting the engine and putting ac on high, open the Freon valve. Watch the gauge until the Freon is full.
Connect a freon gauge and freon can to the low side ac port. Start the engine and turn the ac on high. Open the valve to allow the freon to flow until the gauge reads full.
Freon is added into the low side ac port. Using the proper type Freon, and a gauge that works with that type Freon, connect the hose to the port. With the engine running allow the Freon to flow until the gauge reads in the ok range.
I have the same issue with my avalon. If u have already checked all the hoses and filled ur freon tanks the its most likely a problem with the ac compressor. i priced it at autozone for around 265.
It's almost impossible to get the old stuff now, so you it doesn't realy matter. You'll need to use 134A in your AC system.
