Photo took from google but this hose popped off in my car im not sure if its supposed to have a clip on the outside to hold it in. Looks like it. mine is just a lil thing that pushes in with an o ring. I think it may have broke. Is it supposed to just push in or is there a clip that hold it in there. If so could someone maybe help me with a link to the correct part. I have a 2014 jaguar xj v6. Thanks.

am I replacing the whole plug or I can just take the connector off and put it on mine?

 

 

That is a well known failure point on the AJ133 and AJ126, the plastic degrades with age and heat cycles and becomes very brittle and the clip and/or the plastic tube cracks/splits. Cheap enough to replace the whole tube back to the expansion tank and you need to do that as you cannot obtain or fit the clip/plug by itself, I replaced that pipe/hose on my F-Type with no problems. When I removed the split hose that clip disintegrated in my fingers (as did the entire small hose!). There is no further clip to hold it in , what you see is what you get!
A few on the F-Type forum have fitted aluminium coolant pipes - the big ones across the front of the engine where the upper pipe is known as the cross-over pipe and the lower pipe (under the SC) is known as the Y-pipe, and some have had a problem with that expansion tank tube popping off the nipple on the upper pipe (clearly visible in the pic). On some of the alu upper pipes the nipple that the clip prongs fits over is a bit too rounded and smooth and "unpronounced" so the clip doesn't hold as it should. The fix is to tie a zip tie as tight as possible over the prongs of the clip and so far that seems to be working for all who have tried it.
Bottom line - buy and fit a new hose and add a zip tie to it.

 

Alright I appreciate it. Thanks for all the info. Seems like an easy enough fix. Hope I can get the parts in a timely manner.

 

The link I gave was for the clip and a plug, assuming you're going to fix it quick & on the cheap.
It sounds like you've lost the clip, so you can use the new clip in from the ebay link I gave.
If you're going to replace the whole line from the expansion tank to the throttle body (recommended) call your local Jaguar dealership & ask them for the part number, and/or buy it from them.

 

Consider replacing the failure prone plastic pipes up front. In your picture you can see the fat wide seams in the plastic. These are the old obsolete ones and your on borrowed time with these!

As OzXFR posted above we now have some real nice Aluminum parts to replace those 2 tubes. Well worth it too!
