You have a "High side" and a "Low Side" The low side is usually the bigger of the two and will be the cooler of the two. ALWAYS insert on the LOW SIDE ONLY!

When putting freon in my 01 saturn there is a high input valve and a low input valve, which one do i put the refrigerant in/


You put the freon on the low side, it may have a blue cap to let you know its the suction side.

its usually closer to a long round canister called the dryer or accumulator. when putting freon

make sure to run your ac on high while you are recharging the ac. good luck!

Im trying to recharge my ac in my 1995 audi 90


buy r134 can w/pressure gauge at local parts or department store. Folllow directions on can as far as application. The valve only fits the low pressure line, so there is no way to accidentally attempt charging high pressure side. Unscrew cap, attach valve of r134, check gauge. if fully charged already, do not overcharge... won't cool better, only cause damage.

Where's the low A/C recharge valve in 1995 GMC Suburban?


The valve will be under your hood, on a line that runs from your AC pump, and it will have a blue cap on it. It's about three times as big as a tire valve cap. It sounds like you should let someone else do it.

I see two valves on my ac compressor for my 1995 saturn sl2. Which one do you us to recharge the air condiotioner?


the connector for the rechage kit you have should only connect to one place. the low pressure side. may I ask why are you recharging. the only reason you should be recharging is because it has a leak. I would suggest using a leak kit first. there mabe an oring leak

Air conditioner


the smaller cap, is where it is refilled at, that is the low side, the container will only fit on one of the openings, if fluid or air sound happens and doesnt stop for the neck on the ac recharge bottle then you are not on the right spot. but normally the caps are set as black and blue, but look for the smaller cap, if they dont look different before you do anything remove the caps, put the openings on the caps back to back to each other and look close you will see a difference in the cap size... the smaller is where you need to conect the recharger up to... my guess would be the cap by the cylinder is the smaller... I dont know unless I could see it... hope this helps...
