Update your profile otherwise repeat in every post year and model.

Was this system ever "topped off" and was sealer used? Sealer is simply a band aid and can do more harm than good. Read the labeling on any refill can. Does it have a refund policy if it doesn't work? If you want to see the results of sealer doing irreparable damage, search in ackits.com for sealer damage - all the pictures to demonstrate what goes on behind repairs in a can.

To make proper repairs, buy an inexpensive uv blacklight and use it. A uv light is forever and can find leaks in any vehicle having dye. All Saturns with r134a systems have dye that leaks out with refrigerant and oil. Refrigerant evaporates but dye and oil leave markers. Dye glows under uv light and shining a uv light over, under and around the entire a/c system under the hood should reveal where the leak occurred. Take off one or both service valve caps off to see what dye looks like under uv light. Find and fix the leak to restore full a/c function instead of "topping off" and/or use sealer. Sealer is basically the most expensive repair you'll regret if you use it and find out later the system is completely trashed. One member did and reported the mess with a complete rebuild. He hasn't replied in some years with how the rebuild went.... Your choice.

REWARD EXCELLENCE!
