A hose to feed straight from a 30 lb tank to the low side port can be purchased. However, it is advisable to use a gauge to prevent overfilling.
You are looking for the low pressure side valve. Follow the pipes from the compressor and with R-134a systems the hi and low pressure valves are idiot proof so you can not connect your recharge hose to the wrong valve
In most states you can buy a 134A recharge kit. There is a connector hose and a can or two of 134A. The hose may be used many times, so it is best to hang on to it, and just buy 134A cans after that. Connect the hose to the can making sure not to puncture the can with the needle valve. connect to the A C fitting ( which should have a cap on it that has to be removed ). There is more than one fitting, but the hose will only fit one of them. Start the engine, and turn the A C on as high as it will go. With the can upside down screw the needle valve in on the can fitting puncturing the top of the can. Back out the needle valve to allow the 134A to flow from the can. The can should empty fairly quickly. Once empty check to see if the inside is cooling down. If not cooling down or not cold enough fill with one more can, which should be plenty for most autos. Stay cool.
the same hoses can be used. The dye only tints the Freon but does not hurt the hoses or the system.
AC recharge port. is arms length down the left front of car on top of evaporaterator has a blue cap. Is very hard to reach your arm between the radiator and the motor to reach this port. You should get an extention for the recharge hose. I burnt my arm because you have to have the car running to actually put the 134a in.
Don't. Real Freon ("R-12") is very expensive as it is no longer manufactured or imported into the USA. Take your vehicle to a licensed auto AC shop and have your system converted to R-134a. Also have any other service it needs done now. You can buy a kit that has a can of R-134a and a gauge and hose fittings to recharge your systems, including the Toyota after it is converted to R-134a.
its very simple to do your self. Buy a 25 dollar bottle of R-134A the one with a hose that has a guage on it already. from there jusd follow the instructions that come with it
The AC recharge port on a 2008 Ford F150 is located close to the hose that runs from the compressor to the accumulator. The hose is the low-pressure hose and you will notice a service fitting on the hose which is where the port is.
go to wal-mart or any automotive shop and pick up some refridgerant 134a. I recommend a can with a gauge to tells you how much more you need to fill. Under the hood on the far back wall passenger side you'll see what looks like air hose connection, you fill the 134a there.
Go to walmart and buy a retrofit kit. They include 2 R-134a fittings to put on the A/C lines, 3 cans of R-134a Refrigerant, oil, and usually stopleak. And a recharge hose with a pressure gauge built in.
if it has 134a hose connections, then it takes 134a. if it has the regular thread couplers then it should still have r12 in the system
You can purchase a hose clamp at your local Home Depot, who also offer an arrangement of sizes. If you are looking to buy online you can purchase a hose clamp on Amazon.
It should be 134A, look at the fittings, if there are threads on the outside it's R-12. If they look like air hose quick connects it' 134A
