I am stumped, can anyone guide me to it location ?


Thanks

Paul

 

in the jepc there is some sort of dessicant bag mentioned? is this in place of the ususal style canister?

 

from what I understand the desiccant bag is the receiver/drier

 

I would expect a bag to be a bag but the drier to be a metal canister capable of withstanding the substantial a/c pressures. So, 2 items.

edit: looks like the tech author needs a kicking as it appears to be one item!!

 

The desiccant bag is inside the receiver/dryer. In fact the bag IS the dryer and holds whatever mositure is pushed thru it until it's saturated. The receiver is just the can the bag is housed in.

The idea is to flood or soak the bag with liquid refrigerant most or all of the time. This maximizes the ability of the bag to absorb the moisture that is contaminating the refrigerant.

Maybe, but you don't take the bag out do you? If replacing, you replace the whole drier with its contents, yes?

And why give it 2 different names? Maximum confusion, a bit like the DCCV has at least 4 names?

 

I think you do, the bag is in a tube on the side of the condenser and the replacement instructions warn not to expose it to the atmosphere for more than 5 minutes.

 

Any idea what that bag thing is? Is it some internal part of the "condenser"? I see a fairly ordinary (I hesitate to say normal) receiver/drier in the parts diagram. Never heard of those being disassembled but besides it does not appear to be part of the condenser as that bag apparently is.

 

Your right it does but JTIS doesn't mention it.

Here's a picture of a repair kit for the S type it shows the bag and expansion valve but no receiver dryer.

Somebody must have had these apart surely?

 

I have receiver/drier as part XR8008040 and doesn't look like any of those. Bizarre.

 

Ok, I went back and looked at the Discount ac parts website again for a 2001 S Type and it does show the conventional dryer receiver unit as does JTIS so I think the bad was a facelift mod.
I hope so, I've got a compressor to change sometime soon and I was planning on doing the valve and bag at the same time.

 

Thanks guys, indeed there is only an odd dessicant bag, looks like i will have the metal style one collect dust in the garage. seems odd they never corrected the JEPC on the later models, oh well. I suppose this will be an over priced dealer item

 

Check the prices at discount ac parts, they sell the individual items as well as kits.

 

Thanks Norri!! they had it for 35 and 20$ overnight shipping, after replacing the entire underdash unit, distribution center, ac compressor and dccv I was pounding my head at yet another trip to the ***********! Thanks again!

 

I have read this thread several times but do not find the location of the expansion valve or the drier. I have the parts and the car is apart but I need help,

See this thread for more information but you are right that the change was not very well known and it threw me for a while too!!

The only reason to change it is if it gets clogged. This is why I recommend changing your compressor BEFORE it lets go. The very last thing you want in your A/C system is debris.

It's almost impossible to flush our A/C systems because the S Type has what's known as a split evaporator core. This is because we have dual climate control that allows a different temperature for each side of the car. With this split core you have no way of flushing the core because the flush can bypass any blockage and just go to the other side.

Thanks for your reply.
Yesterday I could not find the drier or the expansion valve so I decided to put on the new compressor and charge the system. Everything went well with the installation and pulling a vacuum but after 2/3 of the Freon something popped. Oil spurted out behind the compressor. I am out of town today and can not check exactly where the leak is.

It may be from a line or ?????

Thanks again, I did see the tube on side of the the condenser, so now I know where that is, also thanks for heads up on the location of the expansion valve and letting me know that replacing it is a major major headache.

Also I see that the dual system is a major drawback as it can't be flushed.


Wow! I have had fun and struggled through some significant projects on my S-Type and I love the car, but I see that I should not have tackled the AC.
