How to remove and replace the air conditioner compressor?

In this video we are going to show you what you need to do in order to replace the A/C Compressor on Jaguar X Type. It is not very complicated procedure. The serpentine belt might give you some hard time because it is very limited room and you need to find a ratchet that will fit the serpentine belt tensioner.

What kind of aircon system does a Jaguar XJ have?

The following refers to aircon systems fitted to Jaguar XJS, XJ Series 1,2,3 and will have some relevance to later cars. See also our R134a conversion mythbuster.

Why is my air con leaking in my Jaguar?

Accordingly, when there is a leak, the area usually looks wet with oil. This is a large ‘radiator’ mounted in front of the engine coolant radiator, which cools the hot refrigerant gas enough to cause it to condense to a liquid. Due to its position it tends to be most damaged by stones thrown up from the road and by corrosion.

How does the air con work on a Jaguar A6?

Later A6 installations used a pressure switch in the same location on the backplate of the compressor which open-circuited the clutch drive if the pressure of refrigerant gas fell below a certain point (about 100psi). In either case, the compressor will not run again until the gas has been re-charged.

How does an air conditioner compressor work in a Jaguar?

COMPRESSOR – The A/C compressor pumps the refrigerant through the system. It’s operated by an engine belt, just like the alternator and power steering pump. The only difference is that the A/C compressor has a clutch that engages and disengages the compressor as needed.

Why does my Jaguar air conditioner need to be removed?

Any moisture in the system will freeze up at the expansion valve and will clog the system, so it has to be removed. Then, it’s back to the compressor, and the cycle starts over. Remember, anyone can perform mechanical work on an A/C system without a license, but no one is allowed to vent any refrigerant into the atmosphere.

Why is my Jaguar XK8 air con not cooling?

Any help/suggestions welcome. Both my 2001 XK8 and 2004 XKR could get uncomfortably cold (as does my current 5.0 XKR) if you turned the temp down, so it definitely sounds as if you have a problem with yours. Are you using a reliable air-con specialist?

What does the condensor do on a Jaguar?

CONDENSOR – This is the thin radiator in front of your engine’s radiator. At this point, the refrigerant is extremely hot and under high pressure–80 to 300 psi, depending on the environmental conditions. The condenser acts as a radiator, removing heat from the refrigerant, and in the process, changing it from a gas to a liquid.

What to do when your air compressor does not start?

When my air compressor will not start I always check the tank gauge to see what the pressure reading is in the tank.

When to run AC compressor on full speed?

As a solution, it is recommended that you run the AC on full speed once in three weeks in winters and monsoon when you don’t use the AC frequently. There is nothing to worry about if your AC compressor running but not cooling.

What does it mean when air comes out of your air compressor?

If there’s a blowback of air, it means your compressor’s intake port is defective. Depending on the design of your compressor machine, uninstall the intake filter and start the ignition. You will feel streams of air coming out of the intake port with your hands.

Can a low oil level cause a compressor to fail?

A low oil level can starve the compressor for oil and lead to compressor failure. CAUTION:Do NOT overfill the the A/C system with too much compressor oil. Too much oil can hurt cooling performance. Use the following guidelines for replacing compressor oil when changing A/C components: Compressor………1.4 oz Condenser……….1.0 oz

What kind of lubricant do you use for a / C compressor?

Newer vehicles with R-1234yf A/C systems require a special 1234yf compressor oil specified by the vehicle manufacturer. General Motors recommends GM lubricants only (PAG-PSD1 #19260643 for 2013/14 Cadillac XTS, and PAG-ND12 #19299051 for 2013 Cadillac ATS). Universal compressor oils should NOT be used in R-1234yf applications.

Where is the a / C pressure sensor on a Jaguar?

A/C pressure sensor/switch: 2. Check the fuse for the Heater Valve. It is Fuse 32 (10 amps) in the Front Power Distribution Fuse Box, located in the engine compartment. This fuse is hot +12 volts at all times, and also feeds the Auxiliary Coolant Pump Relay (4.0L models) and A/C Clutch Relay.

What causes a Jaguar climate control to fail?

When the Heater Valve becomes faulty, it begins to draw too much current, which causes the Climate Control Module to become damaged (i.e. failure due to over-current condition). 4. Harness/wiring problems between the Heater Valve and Climate Control Module. 5. Failure at one or more air mixing/blending flaps. 6. Or a combination of the above cases.

What causes a Jaguar 4.0 liter engine to crack?

On the early V8 models, the plastic guides can crack. This causes a lot of noise, vibration and jumped timing. The cracking of the guides is often attributed to neglected oil changes and a bad design. If the engine has a history of overheating, the guides could be damaged.

How to diagnose a heater leak in a Jaguar?

1. Unbolt the Coolant/Water Expansion Tank, set it aside so it doesn’t block access to the Heater Valve. 2. Loosen the bolt that secures the Heater Valve to the car. 3. Rotate the Heater Valve to get access to its connector. Procedure A (This one is messy. We recommend that you do Procedure B instead.):
