I noticed coolant under the car and I was able to trace it back to a hose that looks like it goes into the engine. A plastic tube that the hose connects to has completely crumbled. I cleaned all of the old tube out of the pipe, but I have absolutely no idea what this part is.

I only have this weekend to try and fix this before I have to go to work on monday. Here are the pictures I have.

 

Hi
If you can point me to where the hoses & plastic tubing is located on the engine, then I probably will be able to find a parts diagiam with the parts illustrated and their part numbers. Take another photo of the engine, but this time show where the broken parts are located in a photo of the right side or left side of the entire engine compartment.

Taking a picture now, but here is some addtl info. It's on the drivers side of the engine compartment right under the throttlebody. It's a plastic part that has two larger hoses connected to it and that little plastic tube that comes out that the third hose connects to.

Hi
I think this is the Diagram with the same parts illustrated as your photo: To get the best view of diagram - left click on image 3 times



Look at Elbow (#9), T-piece (10), Vacuum hose (11), and Bypass hose (12)

Hmm, it is a t-piece, but this pipe carries coolant.

 

Hello again
Look at this Parts diagram of AC/Heating/Ventilation Hoses:



Also look at this thread: go to post #1

This is one of the paragraphs in the posting:
First, the small one - a coolant leak on the driver side, below the throttle, there is a TEE that goes up to the throttle body on the branch, yet the runs are the heater hose assembly (octoupus) to a metal engine coolant pipe. That tee (part no. NNE3944BA) had cracked. $5 part + 1 hour labor = $95

That's the part! Thanks!

Jim,

Do you happen to have the diagram that shoes the hoses under the supercharger?

 

Here is a TSB for coolant leaks.

THANKS!!!! GREAT INFO!!! ARE YOU getting the info from a factory repair manual and if so, are those available?

 

I got this info when I worked at a Jaguar Dealer until 2006. The info was only available in electronic form from the late 1990s onward. Before that it was ALL paper. I downloaded alot of info when I worked at the dealer and I have hundreds (thousands??) of paper TSBs and dozens of coarse study and tech guides.
