RE: Evaporator XJ6 1995
Hi The condensor is located in front of the radiator. The evaporator and TX vlave is under the dash. The JDHT CD ROM does not give any information on how to replace the TX valve or evaporator. I,m really stuck becuase mine is blocked and has to be replaced. Has anybody any helpful suggestions

RE: Evaporator XJ6 1995
CRZYCANUK, I too have a bad evaporator valve. Sorry to be dense, but I don't quite get exactly where this valve is--or heater "bow". The knee bolster on the driver's side?Any help in getting to the valve and replacing appreciated. System is evacuated...may be a good time to replace drier at this point. Haven't looked yet, is the drier a pretty straightforward affair to R+R?

Any help?
Air Conditioning Condenser & Filter/Drier Repl.
Failure of the condenser is one of the most common reasons for loss of refrigerant, as it is quite exposed at the lower front of the car. The filter/drier is mounted alongside the condenser and needs the condenser to be removed for replacement.
To remove the condenser, first remove the radiator top panel which crosses the width of the car at the front of the bonnet area. It is secured by a number of large torx bolts which appear to frequently seize up. If necessary, they will need to be drilled out, or the heads ground off, but fortunately load on this panel is not high and loss of one or two bolts does not appear to be a problem.
Locate the pipes leading to the condenser as they pass to the left side of the main radiator. The union for one pipe is a few inches into the main engine bay whereas the second is on the filter/drier unit, mounted on top of the condenser and therefore harder to access.
Undo the unions slowly, listening for refrigerant pressure. If there is any pressure, then you don’t have a leak and the condenser doesn’t need replacement.
The top of the main engine radiator can be pushed gently backwards and the condenser & filter/drier then removed by pulling them upward. On XJR models, the upper hose for the intercooler radiator, mounted in front of the condenser, makes this more difficult but it is just possible without removing the hose.
The area around the mounting lugs for the condenser is a known rust spot and so you may consider treating it with a rust-proofing agent prior to refitting.
If you have to replace the condenser, replace the filter/drier at the same time as these do wear out and otherwise need replacement on their own.
When refitting the condenser, carefully lower it into the space and from underneath ensure it is settled correctly onto the locating posts. Reattach the pipework and refit the top panel.
The system works at high pressure so ensure O-rings are in good condition and ensure unions are tight during refitting. Always use two spanners on the union to avoid stresses other parts of the pipework when loosening or tightening the unions.

gettin the valve is no problem. Most autoparts store have them available and I can order online for close to 40. I need to find how to get access to it on the car. Do i need to remove the dash and if so where and how do i start? If its accessible from the engine bay, how do I get to it and what do i need to do? Thanks.

Ok, I have sort of the same problem. I had both of the ac lines replaced and did a evac and recharge. The air is still not cold. noticed that with the engine reved up low side pulls down to a vacum, which usually means that the expansion valve is blocked and needs replacing. is the expansion valve in the dash on either side of the firewall or is it actually part of the low side line. what is the (muffler?) thing that the low side valve is in. I can order an expansion valve from napa for $48. how and where do you replace this part?
thanks

can you post a pic or diagram of where it is and how to replace it. is it a new hose? or is it part of the evap. I have been told that it IS part of the evap. If not can you help me locate it.
thanks
