Should be a black cap you will know if it's the right one because the fiting will only go on the low port side.

How much freon does a 97 jimmy hold

It depends on which engine and which AC system is installed, some hold as little as only 8oz., some as much as 55oz. or more. you could start with around 20psi, that's if your using a refill kit with a recharge gauge that's measured in P.S.I.'s!. Add freon while the engine is running and warmed up to full operating temp, fill through the LOW pressure port only (your refill hose adapter shouldn't fit on the high side anyway), and with the AC system turned ON, if it feels cold (35f-45f-50f with a thermometer) and your compressor clutch is spinning and isn't slugged (spinning and than not spinning than spinning again while turned on) your good, if its not cold enough keep adding by 5psi increments till you get to around 35psi to 40psi. If your slugged just let some pressure back out slowly the same way you would let air out of a tire, but don't use your finger, carefully use a long screwdriver.

2005 chevy express ac recharge

looks like it, but the best way to tell is a quick charge port should be the one that is threaded.

What type of freon is in GMC trucks of 1987?

R12.... In 1994 R134a was required, but some changed earlier. Yours may have been converted. If the service ports are threaded it still has R12. Hope this helps.

Which port is the low side port for ac charging on 1997 gmc jimmy

The low side port is always the smaller fitting on the larger line. The high side is always the larger fitting on the smaller line. They do this so that the low side fitting can not be mixed up and placed on a high side port.

Need to recharge the ac system. I see there are two ports within the system. Which is the proper one to recharge my system? 1994 gmc sirra pickup k1500 with 350 motor

if you truck has r-12 you need to convert to r-134
if you truck has been converted to r-134 the small port on the low pressure side is the port to use..
the truck must be in a warm aera about 80 degrees
then hook up the hose or gauges on to low side
start the truck and turn the air on (putting it on high cool and high blower open the can of freon and as the compressure in the truck starts to draw the gas in rock the can from side to side .. if the gas is going in the can will get cold

Blower wont blow out ac on 97 gmc jimmy

pop the hood and check to see if your ac pump is turning or just free spinning if it isn't spinning then u might have tripped the low ac pressure switch and may need to be checked for leaks and recharged
