Crap, AC Recharge?

[Kyle]

Ug I've GOT to do an AC recharge on my 98 GTP ASAP.

Never done something like this, but I like to think of myself as pretty handy as far as car matters are concerned.
Anyone done this?

Is it hard?
I haven't been able to find very much information on such topics but I'm looking.

Any info you guys could give me would be awesome.

Get a set of high/low side gauges, a can of R134a, and find out the high/low side pressure specs. have the car running at idle with the A/C on, temperature setting as low as possible, and blower on as high as possible. Add refrigerant until high and low side pressures are within spec.

i'd do it for ya if u werent so damn far away.

You first need to figure out why you are losing R134a along with the oils for your AC system.

Kyle its not hard to do at all. I recharged my AC in less than 15min I got a can of Sub Zero recharging kit with a reusable gage at AutoZone for about 23 bucks same kit at Target for 20buck found out afterwards. Anyway the Low side connector is located near the firewall by the evap rear of the engine bay. Theres a black protective cap that unscrews. The recharging hose only fits on the low side connector. Just follow the instruction like Silvapain said.

Good Luck

Lee

again, a properly functining system does not need to be "charged".....ever. You have a leak and need to find it. Ive taken a few AC courses and my instructors always warned against those cheap AC refill kits. Theres more crap in them then just 134a and oils for the system. AC really isnt for a do it yourselfer to actually fix the problem correctly. They have a lot of very expensive machinery to do the job right.

well the car is 10 years old and has 120k on it.

I went ahead and bought the little recharge kit. Thats good enough for how much I care about that car now.

after looking at it today, I think my compressor may be dead.

When I hit the AC switch I don't hear, feel, or notice any kind of rpm change.

Do I have a bad clutch?
Or an entirely bad compressor?

 

[Silvapain]

If you're too low on R134a, the low pressure switch will prevent the compressor clutch from engaging. To test the compressor, put the climate control on max A/C and blower on may, and bypass the low pressure switch by backprobing both leads with a paperclip. Also test the compressor clutch gap by tapping the end of the clutch with a broomstick and see if that gets the clutch to engage.

 

[Kyle]

Well I've 0 pressure in the line.
I assume thats very very bad.

 

[Silvapain]

Yeah, I'd say so.

Take it to a shop. Those cans of fix-a-leak do just as much damage as good.
