I think you are referring to the bypass tube from the head to the thermostat housing. Picture might be good here of what you need as it could be the o ring at the heater tube.

If you are needing the head to thermostat housing:
16268-66010 is the short aluminum pipe nipple - you will want one but might get yours apart
16351-66010 is the bypass pipe with flange for bolt up to head - should not need this but I did

16351A-66010 is the o ring at the head - you will need one (1)
16268F-66010 are the two orings on #16268 above - you will need two (2)


Hope that is what you need. Let me know if you were referring to the heater tube running back to teh firewall off the thermostat housing.

Happy New Year.
 
It's the one in the very front. Goes from head to thermostat housing I guess. When I replaced the head gasket the set didn't come with o rings. Is the pn correct?lol
 
^^^^. This information is incorrect.

Guess I am spreading bad info. I had the same leak and ordered those to fix mine. My aluminum tube was pitted and in bad shape so I replaced it. OP noted his was a 96' so I was trying to help. Is there another tube I need to know about? I will order Beno's p/n to throw in the box if so.

The numbers I posted were the ones I used specific to my VIN - 96 model. Dealership about 60 miles away has been spot on with all of the parts I have gotten from them.

Sorry for interjecting confusion.

This break down seems to list the p/n's I used. I got it from Desert Dino's post in recent post about the same type of leak. Makes me feel better as I was worrying how I fixed a leak with the wrong parts. Beno, I am not trying to say you are wrong or start an arguement. Are there two different set ups with different parts for this bypass tube?

E="Desert Dino, post: 11404145, member: 131804"]I would change 3 orings and the metal insert if it was me and my rig

Does anyone have the correct p/n for the nipple marked 16268 above? This thing is worrying me sick. Not sure what I installed and cannot find my plastic baggie with the part number but my invoice from the dealer lists it as p/n 16268-66010.
 
Anyone have tricks to get the aluminum nipple out of the thermostat housing?

I tried a few things and it wouldn't budge. Now I have vise grip teeth marks that may lead to leaking down the road.

I considered a blind bearing removal tool on the end of a slide hammer, but since it's currently working I'm less likely to tear it apart for a solution that may or may not work.
