Good afternoon all,
I haven't posted in a long time but I read this all the time.
I need to replace a bad ac hose on my 2000 convertible. I have bought from jaguar 2 hoses that are the incorrect ? hose. The one I am trying to replace runs from the Firewall ( evaporator ) to the suction port on the compressor. it is a rubber line then turns to metal heading down past the exhaust manifold and catalyctic convertor. it is a one piece line with a muffler in it. for the life of me I cannot see a way to get the new one in (if I had the correct one.)
So far I have the car on my lift and have dropped all the exhaust and the catalyctic convertor on the driver side. I have taken the bolts out of both motor mounts and have put an engine support lift on the engine using the lifting holes in the back of each cylinder head. I have another new hose coming, and already have a new dryer/ reciver in hand. I can get the rubber end with the low side port past the exhaust manifold going up to the evaporator. .
It is the other end with the muffler and fitting for the compressor that I simply see no way to get past the motor mount to install. I must be overlooking something. I really don't want to pull the engine to replace an AC hose. any body done this or have advice?

If the line you have is item #10 on this diagram:

then the part number is MJA7312CB.

Access to the rear of the compressor isn't easy. See if this how-to on member Gus' site of everything helps:
JagRepair.com - Jaguar Repair Information Resource

 

#10 is the muffler. that line plus the one it connects to are what I need. In my car it is a one piece line. I have looked at a 1999 and a 2001 MY and they both are the same as mine one solid piece. I did not find any reference in the TSB's to replacing with a 2 piece hose. that may well be what I need is both halves. do you have the part number for the upper hose? if a new 2 piece style is what I need i'm all for it. I have tried to put 2 different one piece lines from jag. and I had a fully flexible one made. ( it melted in about 30 minutes even covered in fire wrap) So this is starting to get expensive and I do miss my Jag.

 

can you take the wheel off and then remove the wheel well liner to gain access to it??

 

I will try that it must be something like that. will reply after I get back from my shop

 

The old one-piece hose was discontinued and the newer 2 piece is the correct replacement.
We retro-fitted these hoses when I worked at the dealer.

Here is a TSB describing the procedure.

Wow,
I thought I had searched the TSB's pretty well. Thank you so much. I was plotting how to make a 2 piece line.
Let me get these parts coming thanks again Mister Bob!

 

Parts on the way i'll get back to everyone when they arrive next week and I get them installed.

Thanks again

 

Well, The 2 hoses and bolt came in yesterday. I will say the lower hose from compressor to evaporator will fit. sadly the top piece will not. The port to Evacuate / charge runs into the body. it is placed off to the side vice straight up and down. as the original was. this morning I am going over to an ac shop that makes custom hoses in Alabama and see if they can cut the port shorter so I can use it.

Point of my story is the correct part numbers are on the TSB. but I find one number has been supersided by another, than supersided again. I will let yall know how the shortening of the port works out.

 

I had a three part hose constructed. I made a mock up out of hose and copper tubing. it was a struggle to get it in still but after correcting a small leak on the new dryer and an overnight evacuation with a good pump, charged with fresh 134A Freon and it works great. Many thanks Motorcarman for the advice multi piece line is the way to go.

 

glad to hear repairs went well - did you take the wheel lining off to gain access?

 

No I did not. using the Multi piece hose it wasn't required. as soon as I figure out how to post photos I will post how we did it.

 

thanks Rich!!!
