I need to recharge my AC in my Ford F150 5.4 Triton. What freon does it use

if on and off consistently [short cycling ] the usual cause is low or short on freon others are low pressure sensor switch -or clutch failing but the usual problem is freon level

There should be four mounting bolts, and the fittings for the hoses on the back.

jump the ac relay so its engaged that brings the low side press down then the freon will go in then reinstall the relay when ac blows cold

If the year of your van is 1995 or before, it's has R12 freon, if after 1995 it has 134a freon.

These vehicles need a special mechine to recharge the AC. You cant use the old freon cans to charge it up.

The ac compressor will cycle when in the defrost position. The system is designed this way, so that the freon will circulate at times in the system so the seals don't get hard or crack. Otherwise, you would have to replace the seals in your ac about once a year. If it is cycling too often then the freon may be liw and the system needs recharged. If your ac does not work and you are not going to repair the system. You can unplug the compressor so it won't come on and put a load on the engine.

should be located on the left side of the engine. You should see what I refer to as an AC dryer. There should be a place for adding freon.

Not necessarily you may have to test the freon pressure before charging. I would advise first to check the evaporator, the part of the AC under the dash. Sometimes it may just need cleaning. or it may also need replacement. IT may have gained holes.

If system is low on freon, it will not kick in, may be a good place to start.

this should be done by a certified A/C technician with the right tools, the system must be evacuated and then recharged with the correct amount of freon,doing anything less will cause problems. please rate my fix as i strive to be the best,nned more help get back to me
