The kit says to let the a/c system run for a day before checking the oil level. Does anyone suggest recharging before or after doing this?

The kit comes with refrigerant only. If your system was fully drained and/or disassembled (thus no oil in the system), you must add oil prior to charging. They do have a can that will push oil through the charge line just like you would be recharging the refrigerant. The reason for waiting a day before checking oil level is to let the oil get fully distributed within the system and mix completely with refrigerant.

with my ac system completely empty and I mean-flushed with new evaporator and new compressor I added one small can of pressurized pag oil(1oz. size) after having installed my compressor which I prefilled with pour in pag oil(approx. 1oz.). then I added 2 full cans of R-12a. I don't know how to check oil concentration(%age wise), but my ac in my 89 caddy is like the artic and I am happy. I'm not an ac expert, but I consulted with a certified auto ac specialist before converting my system from R-12 to R-12a and also studied all ac documents available on the internet.

It says in the instructions to just precool it for 3 hour's. I don't think that it would be a good idea to leave it running all night. We bought a Ac/dc adapter to get it ready in the house.

I leave the wax in and reuse it. Just plug it in a few hours ahead and it should be fine.

Your local auto parts store, AutoZone or ORielly in my area, can loan you an AC evacuation pump and a set of AC gauges. Hook the evacuation pump up to your system as directed, make SURE it has oil in it when you borrow it. Pull a vacuum on the system as indicated by the gage set (that you have already hooked up to the system). Shut the pump off and watch the vacuum reading on the gage for 20 mins. or so to make sure there is no leak. Then recharge the system as directed. You may want to use R134 with oil. Hard to determine the amount lost. Good Luck!

Air must be connected at all time when evac oil from the engine. Engine must be hot too.

I agree with fireatwill's reply. Mine sits for weeks and works OK. I "top off the charge" usually when the green test light and the adjacent red light goes out. Be sure the connections are very securely made to the battery. You likely will not have enough power to crank a completely dead battery on a large high compression engine.

probably 1 hour, you need to maintain the tank pressure so it would suck the oil, but you dont need to stay there, you can just hook it up and come back once it is done, normally I do it at night when the car would be sitting in the garage

Try playing with the choke or disconnect the low oil sensor wire (female male plug). They say that metal particles in the oil affects the sensor. After the first 5 hours of run time you should do an oil change

The only time you have to worry about the device is if the car is taken into a shop for repair of engine issues. Brakes and tire rotation or oil changes are no problem. IF the engine is acting up, the technician will plug their computer into the socket. It does not drain the battery, it actually goes to sleep when there is no motion. I really recommend this, it gives my wife and I confidence that we know where our child is. The reporting is excellent. I recommend the "right angle extension cord", this allows you to put the OBD up in the back part of the dashboard. Use some black electrical tape to secure it.

Add a few drops of oil prior each use to the air inlet or install an automatic oiler to your system

No you have to put the oil after you receive it. If you don't use it in over a week the oil will leak out. So if you are not going to use it regularly drain the oil

as long as the car is running, don't shut off the car without turning of the heater.had it hooked up to a battery charger/jump starter only lasted a few hours

I don't think you should leave it plugged in. I charge it for an hour before a planned use but when I simply grabbed it and ran, it had enough juice to start an 8 cylinder jeep.

Just bought one. Nope, I picked up a recharger kit that comes with the oil.

That's what they say, I change mine every 4500 or so. If you want to test it they have a company in Dallas Tx were you can mail a sample to see if the oil is still good. Hope this helps

ddepending on how much you use it and whats plunged in. You can order a a/c adapter for it that's what I did, the batters only last a few days with minimal use.
