What is the correct name for that lower intake pipe that goes to the heater core?



I do not want to tap any threads.

I been noticing that problem myself. lol

Slinky, its a 3500 not a measly 3400.

[slinky]

Yeah i know, its that powerhouse with the extra 20hp more than the 3400

[1988GTU]

Something fierce is how I like to put it.

C'mon slinky find me that oring!

Grab 3100 Beretta lines, then cut and weld the o-ring piece that goes into the LIM to the one beretta line at the right length. Then bolt it up to the head like stock. Then the 3500 won't be modified in any way.
Either way a 3100 beretta line going to the water pump will bolt up like stock. The other one going to the LIM will have to be addressed some way...

I have the metal tube mocked up and ready to go pretty much, I just need that oring that attaches around the pipe that goes into the LIM under the T stat to make it sealed up. Smell what I am spraying? See what I am trying to draw.

Oh, I was looking at the arrow on the end of the pipe.... Not where it goes into the LIM.

Just go to a parts store and match it up with a box of o-rings (that's what I do when re-using the screw in type)... LOL or go to the dealer and have them bring up the picture on the computer with the exploded view and pick it out...

I kinda wish it was that easy for using the old o-ring... My pipe doesn't have the o ring on it... MIA shop pan or in transit.

I also am trying to avoid this dealership field trip, I ran out of oil for my buttocks and I am afraid to feel what it's like without the lube.

[IsaacHayes]

LOL dearlship o-ring won't be much. I go there for the special teflon o-ring for the oil drive shaft, AND get a distributor gasket and it cost me like $2 and some change out the door.

Or measure with some calipers and try several sizes from the parts store... don't forget thickness too. My old o-ring was smashed down but I estimated what it should be new and was dead on.

Here are a couple of images of the set I took off of my LX9/3500. I used my existing LA1 lines and quick disconnects.

I suppose that you mean the O-ring shown in the third image?

[1988GTU]

YeeeAp that looks like it.

[slinky]

like i said quick connect just like the 3400
