To fill the proper amount of refrigeration oil, you wanna take the cap off the rear. Still won't hold a vacuum.

Sometimes you may see an oil/dirt residue that has accumulated at the spot of a leak due to this oil mist.

How to add oil to car ac system. Connect both blue and red gauge hoses to. Some refrigerant charge and other useful specifications are provided 2. When people refer to pag oil they typically refer to it in the following terms:

The oil amount drained from the old compressor (b) is 50 cm³. Otherwise, make sure you measure out the correct amount of refrigerant oil and ensure it is the correct type before you add it to the system. Adding oil to the ac system in most cases the only time you will add an oil charge is if a component is replaced in the system.

Insert a funnel that fits into the opening and slowly pour the recommended amount and type of oil. Add the right type and amount of oil and secure the rear cap. You're gonna need some sort of measuring device.

Blend air door is the reason for drawing hot air to cold air in your car system. In order to remove oil from an ac system, the system would have to be disassembled and the components flushed with a special solvent. Remove any caps or barriers as instructed and assemble the refrigerant replacement system, typically a can of the fluid and a trigger/valve top.

Pag 46, pag 100, or pag 150. When you replace a major ac component, you must add oil to the system. Specifically a compressor or receiver dryer or sometimes called an accumulator, will hold a fair amount of refrigerant oil.

Follow instructions contained with new compressor concerning amount and type of refrigerant oil to put in system. Remember, this product is a compressed gas in liquid form. This oil meets all specs for ac systems requiring pag 46 oil.

Oil can be added to the system in two ways: The total amount of oil in the new compressor (a) is 120 cm³. My point here is that if you want to err on the side of caution, don’t add any oil to the system.

Once the bottle was in the system. Compressor.1.4 oz condenser.1.0 oz evaporator.1.5 oz accumulator.1.0 oz hoses.1.0 oz the total amount of oil added to compensate for parts that have been replaced should not exceed the total oil capacity of the system. Use the following guidelines for replacing compressor oil when changing a/c components:

With oil injectors or through the low side port under vacuum. Too much oil will reduce cooling performance because it coats the walls of the condenser and evaporator and reduces heat transfer. This captures the refrigerant and does not allow it to escape into the atmosphere.

Make sure everything is clean before you empty the oil into the measuring device. Whenever refrigerant is lost oil is also lost with it as the oil under pressure becomes a fine mist. The numbers represent the viscosity of.

If you don't know what the total oil capacity is, check the underhood. Pag is actually an acronym for polyalkylene glycol, and it is a synthetic oil used in a/c systems to lubricate the compressor. The entire process is enclosed and safe so that none of the coolant is allowed to leak out.

Pros / enhances ac system function and life after repairs cons / this is an oil only, not a refrigerant When you take your car into a mechanic to get the job done, they use a machine that relies on an airtight seal and a vacuum to pull the excess coolant from your system. Please note that this is not an official installation or instructional guide.

Take the open end of the low pressure line (which is blue) and screw it on to the low pressure port in your engine bay. Put all the oil emptied out of the compressor. This will be your best bet.

When the engine is on and the ac is on high, low pressure readings should be around 30 psi and the high pressure side should be about 250 psi depending on your car. Hook up an ac manifold gauge to inject the dye. For some applications it is necessary to add oil.

I decided to try the dye. The correct reading will display once the clutch engages and the gauge stops cycling. Most all newer model cars use pag as the lubricant in the a/c system.

Add oil to the receiver/drier. Too little oil, on the other hand, can cause damage to the. This door is located in the ventilation system.

So if you didn’t do this, there’s still the old oil in system components. You should be able to get oil and the amount you should add from your dealer. Put a small bottle of freon in.

Make sure not to overfill your air conditioning system, you want to find the sweet spot, and the pressure gauge is used to find the proper amount of refrigerant for your car. Most a/c systems use pag oil, but a few use polyol glycol, so it’s important to determine which is used in your vehicle. It is impossible to tell how much oil is in your ac system, but if it was evacuated before you put the new compressor on then you should probably add some oil.

How to drain and add ac compressor refrigerant oil video. Add the correct amount of oil, as determined from the previous step. The procedure to add oil through vacuum is described.

Put an ounce of oil in the dryer. An evacuation only removes air and moisture. Look for refrigerant cans that have oil already in them.

Hold the compressor so that the open end is facing upward. For some applications it is necessary to add oil. Here is a video on recharging your.

Pop the hood and hang a manifold gauge from the hook at the top. So, make sure that you check the compressor as it could be the reason why car ac not blowing cold air after recharge. It’s worse if you add too much and cause a problem.

The fan kicked on, and the ac clutch engaged. For example, where there is one and the same part number for single and dual evaporator cycles or when the oil. Yes, it’s a good idea to add a bit of oil.

Stuck & blend air door. While adding oil to an ac compressor, you must first evacuate the system with a recovery machine. Use the exact oil specified by the carmaker and don’t overdo it.

The general rule of thumb on how much oil to add to ac. You can use the bluedevil oil injector (available here: And adding any more will be too much.
