Since I have developed a coolant leak after replacing injectors, I've decided I might as well replace every plastic pipe and hose I can. I have every part in my shopping cart except the 2 Y pipes. I'm talking about the 2 pipes where, if you have a supercharged version, they can be found in metal. I'm wracking my brain trying to find the plastic ones for the NATURALLY ASPIRATED 5.0 V8, and every parts site and diagram I can find points only to the SC version, whether metal or plastic. I can't find a single post in the forums where anyone has replaced them on an NA engine either. My mind has turned to mush... Am I crazy? Does the NA cooling system not even have those 2 pipes?? Does anyone have the part numbers or a link to a diagram? Thanks!

 

Hi Sandcat & welcome to "THE FORUM"!!
Our 2012 XJ NA has been great, hope yours will be as good to you too.

The NA engine doesn't have the same frontal cooling pipes as the SC.
The outlet pipe for the NA is AJ89664 and isn't available in aluminum - yet...
Thankfully for us NA owners, the cooling system has a couple less parts.
See item #25 in this diagram

Much appreciated! Part finally came in... Now to get a pressure tester and start this nightmare lol

 

Don't forget item 27, the rear crossover. It is a VERY common failure point, and a chore to get to as you need to remove all of the cowls at the rear of the engine compartment.

 

VERY good advice above from Enosgl.
Do it all at once so you don't have to go back in again and again as things fail one by one.
