LIQUI MOLY PAG Air Conditioning Oil 46 | 250 ml | Compressor Oil | SKU: 4083

Product Information

Although they all fulfil the same function, there are several types – reciprocating (piston) and rotary – of compressors and which is fitted is broadly dependent on the age and therefore, development of the air conditioning system in the vehicle.

Having a robust air conditioning system that can keep your car at the right temperature is absolutely crucial. Our professionals can use the right compressor oil for your car to ensure that your air conditioning works smoothly. What makes these PAG oils from the BEHR sales brand special is that they are not only suitable for use with the refrigerant R1234yf but can also be used with the refrigerant R134a.Apologies for not responding sooner but like thousands of others, this weekend was largely spent stood in a field watching bands. I’m aware that much of the oil is in the compressor but that it also naturally distributes around the circuit, what I don’t know is how much is still in the system and don’t want to overfill it. Too little and the compressor will be starved of lubrication, creating friction and a build-up of heat. Our experts can check that your air con is working properly, and help you resolve any issues quickly. As a starter you will need to ensure you have a clean system, usually we used Nitrogen to blast through any rubbish and old oil from the system.

Once you have ascertained the approximate amount of oil that's been blown out you could, if you really want to, remove an amount of oil. The different types of PAG such as PAG46, PAG100 etc… reflect the varying oil viscosity (the measure of an oil’s resistance to flow) and the refrigerant it’s designed for. If your vehicle lacks compressor oil, there will be some telltale signs like humming sounds, refrigerant leaks, burning smells, and visible smoking. The TT AC system has a total PAG oil capacity of 135g but with a newly drained compressor and new condenser/dryer, how much should I put in? A special, non-conductive compressor oil is usually required for hybrid vehicles and air conditioners with an electric compressor.

To wet seals during assembly, apply Liqui Moly PAG Air Conditioning System Oil 46 with a brush to ensure that the system is well sealed.

One thing I’ve always been interested in “hacking” - the aircon won’t run below 5C ambient temp, which has always felt a little high to me as misting and condensation in cold weather are a pain, especially in the winter months here in the UK. For a pound more I would certainly recommend the longer lines, you don't want to arse around trying to place the set of gauges on some vibrating engine part when you can hook it onto the bonnet catch. Choosing the wrong type of oil can negatively affect both the performance and longevity of the compressor. Our team of ASE-certified mechanics can change your car’s compressor oil and address any additional A/C system issues.PAG oil is hygroscopic which means it attracts moisture from within the air-conditioning circuit or atmosphere. Not only does it lubricate the compressor’s internal components, but it also acts as a sealing agent for rubber components such as hoses and seals, absorbs heat, and in some hybrid vehicles, prevents electrical damage to the compressor. Any shed should have an F-Gas certificate, the fines for a commercial establishment breaking these regs are severe.

Depending on the A/C compressor in your vehicle, you may need to change the compressor oil more regularly. I am pretty much ready to bolt in the "new" compressor and condenser and dryer, with the plan to get the system leak tested and regassed shortly after. The fixed displacement compressor, the oldest design, features a set swash plate that operates the pistons necessary to generate the throughput of gas, at a constant volume per rotation, so has to use a clutch pulley to allow it to, in effect, be switched on or off when the air conditioning is or isn’t required.But again, I've never taken oil out of a new compressor, but if pushed I would remove about an egg cup full from the new compressor. They are actually unable to form a long-lasting homogenous mixture and will separate after a short period of time when the compressor is not running. You do this as an oil molecule is larger than a 134a refrigerant molecule, so try not to let the shaft seal "dry out".
