Look on the firewall, on top of a skinny canister.

High side and low side ports are different sizes.... keep looking. These cans are designed to be connected to the low side port. I'm not a big fan of DIY AC repairs, especially when the can contains sealers (these can make it so no shop will touch your car). Modern AC equipment can be spendy to repair and I don't know of many shops that don't "prove" the AC charge before servicing.

The low side port on your Tempo is in the paseenger side rear corner of the engine compartment on the side of the accumulator. Stand by the passenger fender, put your head down by the hood hinge and look down. It takes a 90 degree fitting or quick connect to hook up to it. You won't do it with a straight hose or a can with no hose.

I agree with Jim, AC repair is not really a DIY job. There's a lot more to it than just "recharging" the system. If the refrigerant has leaked out, so has an undertermined amount of oil. Getting the oil right without the proper equipment is like adding oil to your engine with no dipstick. The leak in your system is probably in the connection just below the service port that you found, or the compressor shaft seal. Both are real common leakers on Tempos.

Thanks I will look for it there. Probably covered with dirt or something. If it doesn't work, I will take it to a garage. Steve
