any autozone or orileys has the kits
I've seen the combination R-134/Oil/Dye/Sealant cans at Wal-Mart. One can typically runs around $15 USD. I'd suggest one of the combination cans, and one or two of strictly coolant, depending on the required pressure. Kits including the required hose, pressure gauge, oil, sealant, refrigerant, and dye run $27 USD plus tax at Wal-Mart, as well.
R134 is used, but have the leak fixed first.
It came from the factory with R12. Due to the cost of R12 I suggest you have it converted to run on R134. Have the leak fixed and convert it to R134 and save yourself some big money. R12 is no longer in production, and is very, very, expensive.
The 1992 GMC Suburban came from the factory with R12 not R134. Unless it is has been converted to use R134 you cannot simply add R134. If it has been converted you need to have the leak fixed before adding anything. It is illegal to add refrigerant to any system without first repairing the leak. How much it will hold depends on how much leaked out.
First, your 1998 Mercury contains no Freon which is R12. It contains R-134 refrigerant. You add R134 at the low pressure port. But the fact that you need to add R134 indicates you have a leak. It is illegal to add refrigerant to a system with a leak without first repairing the leak. Seek professional help and have the leak repaired.
Enough to recharge the system after the leak is repaired and no more.
No, unless you have a refrigerant leak.
There are plenty of different epoxies on the market, use one of those. Advance auto parts has a lot of them.
Perhaps you better not. In some states it is illegal to work on auto A/C if you are not certified. High pressure gas can freeze body parts.
There is a leak somewhere in the air conditioning system. Mechanic shops have a special dye they can add to the system to find the leak.
recover all r134 a and do a vacum test and if leak inject die with r 134 a and run for a day or to and check with black light
FREON (R12) was banned beginning in 1996. Your vehicle contains R134, and as to how much. I suggest you seek a professional to repair the leak and recharge the system, as it is illegal to install refrigerant without repairing the leak.FREON (R12) was banned beginning in 1996.
