You have to measure the oil in the old compressor and then add a small amount, usually about 2 oz's this is for a system that has been run, the oil circulates with the refrigerant, so oil is in every component, you really need to consult a factory service manual to come up with the proper amount, it is based on which components you are replacing. Bottom line is what ever you drain out is what goes back in + a small amount, if you get it wrong you can end up with a frozen up compressor or a system that does not cool correctly.

How much oil a/c compresor need on a 1997 jimmr


You do not add oil to an automotive A/C compressor. When you do a refill with a proper coolant, it will have any necessary lubricants.

Ac compresor do not start


Check the high and low pressure switches in the system as either one will stop the a/c compressor from working and causing compressor failure.

1987 Corvette when parked overnight in the garage drips a clear fluid not oil or anti freeze


Where in relation to the car's underside is this fluid coming from?

Side: Check washer bottle reservoir, any fluid filled engine mounts, and power steering hoses and reservoir.

Middle: Check engine sump, front and rear crankshaft seals, and gearbox seals.

Also if you drive with the airconditioning on, then the airconditioning drain vent for condensation is usually just slightly off centre, behind the engine. This is normal though, and doesn't constitute a fault.

If you can jack your vehicle up and inspect it, this would be the best thing.

Good luck.

Compresor dont get current


Autozone.com has diagrams for free when you register your car on their site. You can test the low pressure cut-off valve downstream from the evaporator tank by disconnecting the harness from the switch and using a good size wire to loop into the harness.

If the compressor clutch kicks in, you have either low system pressure or a bad low-pressure cut-out switch. This is a test procedure. Even bypassing direct as you have done can risk damaging the compressor.

Besides Freon, compressors need oil, the right type, and a small amount. There are Freon cans which include an oil charge as well as sealers and conditioners to prevent or fix leaks. Remember that the system has a volume limit and more additives leaves less room for the Freon to work good.

If you have low pressure, it is possible that what is left is contaminated. Freon is a gas. Air is a gas. The system was suppose to start with Vacuum negative pressure by using a Vacuum pump(Loaner item). This means that total volume inside your hoses could be wrong. It is easier to understand when you consider the Freon changes back to a liquid and Air needs a much lower temperature to become a liquid. So you lose volume for the Freon to change back from liquid to a gas. It constantly cycles like this to make it transmit heat from the cabin to the outside.

I hope my solution is helpful.

A/c compresor not engaging


Yes, freon must be present in the system in order to circulate the oil that lubricates your compressor. A low pressure switch is used to stop the compressor from running if the freon level/pressure is low. This is to keep your compressor from destroying itself due to lack of lubrication.

There are also several other reasons that an A/C compressor will not engage. Proper diagnosis is required.

Hi my minione.2x overheating..smoke comeout,aircondition diffreht sound..whats the problem


I may have read your question incorrectly and im sorry if i did, but if there is smoke coming out then that most likely means that you are burning oil.. a broken or bent piston ring causes this, because the oil is slipping through the cracks into the top of the cylinder and cumbusting with the fuel and air mixture.

Our car is squeeking when we turn it on or run the air before its warmed up.. we have already changed the belt... any other troubleshooting??


Either the belt is not tight enough or your airconditioning compressor is low on oil. If the low oil is the problem, you are about to have an expensive problem when the compressor fails. So: be sure the belt is tight enough. If it is, get some oil added to the compressor. It's a special type of oil called PAG oil, by the way, so be sure to get the right stuff.

How do I fill air conditioner coolant.compressor is new, but I need to add coolant.


You need to evacuate mositure with a vacuum pump and then add a can of r134a with oil in the can. Then add more cans without oil. Up to the amount on the decal under the hood.
The low side charge port is behind the passenger fender well. Remove tire and the 7 fasteners holding the plastic fender liner in.
