The owner's manual does not have that type of information in it anyway. You would need a service repair manual. The service manual would tell you how much refrigerant is required to fill the system of that make and model of vehicle. As for the amount of oil required for the AC compressor if it is OEM the technical service manual has that information if it is aftermarket replacement just intimation should have been in the box when purchased if not contact the manufacturer.

I would do a cost analysis first. Do you have the necessary tools including a vacuum pump and manifold. How much will it cost to replace the compressor if I damage it? How expensive is a condenser coil if I put in too much refrigerant? What type of oil is in the compressor now? What refrigerant is being used? Do you have a leek detector?

If you cannot answer the above questions or afford the replacement parts I would suggest taking it to a pro. If you need oil and refrigrant then you have a leak that needs fixing first.

Where do you fill up the freon


You leave air conditioning to a professional that
is trained to work on those systems, or you will
let air into the system & ruin it.
If you suspect it is low,then it obviously has a leak
that needs to be repaired
No vehicle system consumes fluids of any type.
Need proper equipment to test & add to a/c or you
may over charge it or get it into you eyes or burn your
skin.

Air condition


If you've never worked on an air conditioning system before, I would recommend you take it to a shop and get it checked out.
If the system is low on freon, you have a leak that would need to be fixed to keep any freon you add from leaking back out. And it could have an electrical problem instead of being low on freon.
Freon gas is minus 35 degrees when it comes out of the can.

How to add refrigerants? To a 2000 buick lesabre.My car is blowing hot air it went from cool to hot. and now it just hot air coming out.


look for the fitting that is the smaller of the two and is attached to the line that is the larger of the two, this is the "low" fill side, add 2 cans of r134a freon each can is one pound the system empty holds 2 3/4 pounds of freon thats 2 3/4 cans.
I would buy 1 can of leak detector/freon combo and one can of dye/freon combo, if it takes more add a small amount of a third can that has an oil mixture in with the freon that would complete your systems needs the cheapest and fastest way possible.
If you want it done to the book then you need to have a certified A/C man vacumn pump down the system, replace the reciever drier, add freon and oil to fill the system and then check for leaks.
Happy Motoring!!

The air conditioning compressor cycles continuously, sometimes cutting off the engine, and there is no longer cold air coming out.


Try to add freon,it is most likely low,and needs the recharge,also,if it leaked freon,it leaked oil,so put some oil in it also,If this was helpful,please rate,thank you.

I was just recently in a car accident. My raditor broke and had to be replaced. Because i didnt want to pay a mechanic to do it i did the job myself. It worked out well but after dissembling it the coolant...


first you need to find out why the freon leaked out then repair that, then you will need a vac pump to vacuum the system for about 45 mins then if you lost oil add a couple of oz,when you lost the freon if there was a cloud of oil and gas then add 2oz before the vac down while system is open put into line or dryer or condensor, after the vac, then recharge to spec, there a label at the radiator support or on the hood that tells you how much freon the system holds,here you go it holds 1.48lbs of 134a freon.

My air condition want' blow out cold air i try


If your car is more than a few years old, it probably has a leak or a worn compressor. You can add too much freon for the system. It needs to be vacuumed down to a negative pressure before adding freon, and then checked for compressor function and leaks. You may need to take it in to a reputable shop.

2005 Altima 3.5 air conditioning blows warm air at temperature over 85 degrees.


All three of the above answers are incorrect. There is no need for freon to be introduced into the system, if the system is fully charged. If you do this, and follow the above advice, you will damage your AC compressor. What you need to do is get the vehicle hooked up to a set of refrigerent gauges at a local competent service center, and the pressures will tell your competant mechanic what to do next. NEVER 'add freon' if you are not 100% sure that the system is low.

My ac wont work


Must be Air-Condition System Lines/ Hoses leaking R12 Freon (gas).

MAYBE THE PULLY HUB BEARINGS FAILED OR
DUE TO VERY LOW R12 FREON (GAS ) will not work.
Because there is a switch in the receiver/dryer prevent AC from working when low R12 Freon present, to protect the system & compressor damages.

You must fix the leaks, before recharging it.

They must **** the old (residue) gases from the system & lines / hoses...... & stay in the vacuum pump 30 minutes to proof no more leaks.

Recharge some oil for the old type R12 Freon gas.

Before recharge it to 62-67 psi R12 Freon
