1997 F150 Ac ?
I have a 5.4 the ac clutch went bad mow im playing the belt game trying to bypass it.I dont want to remove the pump unless i have to.
I bought a belt for a 1997 no air for my truck and it is to big?
I dont have underdrive pullies and the diagram under the hood shows the tensioner lowerd but it looks to me like it cant be relocated.
I there anything I should know before i remove the pump ?

Use a Hammer.
It's not really the pressure that's unsafe, it's the refrigerant. And even that's not so bad as long as you don't inhale it.
Back before the days of ozone and atmospheric legislation, we used to use a hammer to depressurize A/C systems. Those days have long passed.
Remember that dumping refrigerant into the atmosphere is illegal. Even the R-134A, which is ozone friendly, is not supposed to be released. That's the major hazard. Your tires have higher pressures than the A/C system.

I doubt your tires have that much air pressure in them.

Even at 100 psi, the schraeder valve won't be a hazard.

The pressure won't drop that low until the system bets below freezing. Attach a guage to your system one of these days and make your own observations.
At 60F, the pressure is still going to be over 80 psi.

The pressure doesn't really matter. Get it done at a shop. The refridgerant is bad for the ozone and it is illeagal to release it. You need to be certified to work on a A/C system. Also it is extremely dangerous when this gas comes into contact with heat. If turns it into Fosgene (not sure of the spelling) gas, also known as mustard gas. It can also kill you as there isn't any oxygen in it and it is heavier than air.
