Trying to recharge A/C system in 2003 Frontier CRew Cab. Do you have a diagram of system so I can locate high and low pressure lines.


To recharge A/C system in 2003 Frontier Crew Cab. Brother, don't concern yourself about the technical stuff of which is high or low pressure line. The refill/charge kit line will only fit on ONE of the 2 line fittings anyway. The line fittings I speak of are covered with a plastic cap like the one on your tire valve stem. Get your recharge kit from parts store, get mine from NAPA, with the line and a bottle of Freon. Find the charge fitting, usually on the passenger side under hood not far from firewall. Take the cap off and put it in your pocket. Open the kit, screw the piercing pin of the canister end out and put that end on the Freon canister. DON"T pierce the canister YET. Screw the other end on the charge fitting of your system and start the engine, turn on the AC on high, NOW pierce the canister top by screwing the knob/t-handle all the way in and then back it out half way. This will allow the Freon to escape the canister and the AC compressor will pull it into the system. Now, I've one trick for you. Before piercing the canister, get a small bucket of HOT water and have it there at the vehicle front. Soon as you pierce the canister and back the pin out half way, stick the canister into the hot water in the bucket. The heat will force ALL the Freon out of the canister till empty. Once empty, remove the kit line from the charge fitting on your vehicle, remove the canister from the kit line, trash the empty and hide the kit line where you can find it later, dump the water and put the bucket away, and go sit in the cool. One canister should take care of the recharge. If you put too much in from another full can, it may overcharge the system and still have no AC. That's just the nature of the beast. If it leaks down, get a leak detector kit from same place you got the recharge kit and find the leak. They also make a literal "Stop Leak" kit for AC systems too. Same place will have it. Brother, old school on this stuff. I figure things out quickly. There's no reason why this I told you won' work. It's what I do. Have fun Bro.

I want to recharge my AC unit. Not sure where the refrigerant is supposed to go


You connect your refill can or system to the low pressure line. Here is the good news. The fitting on the refill kit will only fit the low pressure line connector. They appear as over sized Air fitting. Both High and Low pressure sides will have plastic caps on them but your coupling will only connect to the low pressure side.

I am looking for the lower ac charging port,on a2001 ford expidition


The low side pressure fitting usually has a black/green/etc screw on cap and can be found on the silver a/c line. This line leads from the a/c accumulator (receiver) to the compressor. The accumulator is a large silver canister with a line that leads straight to the compressor. Your recharge kit will only fit this quick lock fitting so theres no chance of hooking it up wrong. Also, keep the canister upright as large liquid amounts will damage the compressor.

Good luck! Recharging a 134a system is a whole lot easier than it used to be!

My recharging kit for air conditioner doesn't seem to fit recharge valve on 2004 dodge durango. How can I be sure i am looking at the low prerssure valve?


Newer vehicle come with R134 vs R12. Since the two are not compatible, R134 has larger fittings. AC system has two ports, High and Low. Low is return to AC Compressor and high is output. High port is first following line from compressor to condenser (condenser is at front of vehicle like a second radiator). Keep following line till you find high port (paint cap red). Second port is low (paint cap blue).

Where to add refrigerant to a 1997 gmc sierra. It looks like there is 2 places 1 is pointing up and 1 is pointing out. 5.7 V8


Look on the threaded caps that cover the connections,on top of the caps one should have a L for lowside pressure and the other a H for high side.Add the refridgerant to the low side.If your doing it yourself and buying a ac recharge kit from a parts store or shopping center, the kit comes with the refridgerant and the hose you will need to recharge it.The hose fits only the low side connection on your ac line and willnot fit the high side,so you shouldnt have a problem.Hope this helps you.
