Where do i hook up the freon? looking for port to add freon .

You need to hook up to your low side port. It is located on the passenger side a/c hose assembly next to the strut tower. It "should" have a blue or black cap on it.

I have a 2000 Lesabre and it is located on the passenger side of the engine compartment right on top of the Canister. There are two ports, one is larger than the other and both have a threaded plastic cap on them. The smaller one is the low side where you can check your R-134 pressure. Start engine and run the A/C on MAX. Remove the plastic cap from the smaller valve connect your gauge to that valveFollow the instuctions and tempurature specifications on the R-134 package. There ya go man, as you're hooking up the refill line hit the trigger so u don't allow any air in the lines instead of just straight freon.

There is aa line coming off air compressor if you trace it down there are two valves on it was screw on caps. The smallest valve is where you hook up freon hose to add freon. I hope this helps, any clarifications needed fell free to ask.

The ports are keyed - you found the proper port if you have the proper hose. If the Freon will not go in - and you have complied with all the package instructions ... right? ... Freon is not your problem. Going much beyond what you have done already is dangerous. Please have your AC looked at by a licensed AC Service Mechanic.

Thank you for your question @ FixYa.com

the low pressure port is under the altenator this is were you need to hook up crank car turn A/C to max read directions on freon can

Yes you can add freon, the port will be on the line up at the accumlator tank (large silver tank on pass side close to the fire wall - will have a large black cap, does not look like a port) Get you a large can with a hose attached do not use it all save some for next year. 

maybe on ac compressor look at large ac line out of compressor and follow it untill u come to the low side port,it is the smaller one of the two ports but only one will hook up to single charge hose

Find the A/C compressor. Look a both lines going to it. One line should be bigger than the other. The bigger line is the Low Side (suction port) follow that line it goes to the firewall to the evaporator that is in your dash. The low side pressure port is somewhere in that line between the evaporator and the compressor. That port is where you check low side pressure and add freon. Don't worry if you buy a charging kit from a part store you can't hook it up wrong, the low side port and the high side port are different sizes and the hose won't fit. With the A/C running on high, low side pressure should be about 35psi.

#1 you will need r134a freon. #2 the low side service port is located right at the firewall where tha line goes to the evaporator. #3 if wou bought a can of 134a freon with a hose that will hook to it, it will work. all service fittings for 134a freon are the same even though the high side and the low side will always differ
