I have a 2.4L RHD MK2.
The upper hose is quite old, and needs replacing.
The number is C21499.
I ordered one out of a good supplier I use regularly, with outlets in England, the US and Europe.
What I got doesn't fit anything on any MK2 I ever saw (smaller diameter by a bunch, and a 90 on one end).

Numerous discussions, they found the parts might have been mis-marked.

So, they sent me the correct unit.
This hose does not have the two ribs on it.
They claim (and I believe them) that the 2.4L did not have the ribs like the 3.4L and 3.8L did.

Any of you smart UK folks know for sure?

There are many differences in a 2.4L version, and this may be another one.

Thanks.
Dave

Well, George, this one vehicle has become a challenge for me.
You know from the correspondence before.
I LOVE a challenge!
Now all I need is to get a copy of some master Jaguar Parts catalog page showing what a C21499 looks like to put with my errr.....documentation.....to take to meets.

You have no idea how many minds of judges get absolutely blown away with the differences in a 2.4L.
Nice, experienced, knowledgeable folks who sit around after the judging and we go through all the differences.
Had one, after it was all said and done, ask if he could sit in the boot....and look at the underside of the lid.
The look on his face made my day, when he climbed out with wide eyes and said, "There are no holes!" (for the additional boot emblems).
Single outlet pipes blows their minds, the fan shroud, or finger guard.......
Basically, I guess, I'm a local historian.....showing what ELSE Jaguar built that most folks in the US have never seen.

It is fun......and sorry if I come across as intense.

Dave I suspect that if you show a RHD 2.4 L car here in the US most judges will flip. Heck I have seen a gazillion Jaguars but I have driven more C-Types than I have seen 2.4 cars.

Well Dave the parts manual for the 3.4/3.8 lists C28972 for late cars, C27106 for middle and C 21499 for earlier cars and C 12424 for the first cars. C21499 is a straight hose w/o ribs and has a bend in it.

I am reasonably certain the supplier, who has done this for a while, is, well, right, or at least he is convinced he's right.
I am asking everywhere, because, as I bring this car up "to snuff", I don't want to be arguing with some Judge someplace grassy about it.
I HAVE the documentation on the rest of the different 2.4 bits, but, if you say the part number shown is the same part (with ribs or ridges) that is used on a 3.4 or 3.8, I WILL return this un-installed.
Before I put it on the car, I need to make sure.
The C21499 you show for later....since I do not have parts manuals for 3.4L or 3.8L....is it the same part number for those?
This hose has C21499 on it.

THAT'S what I'm asking.
I suspect, do not know for absolute certainty, enough to be willing to engage in an argument.

I do not know what a C21499 looks like.
My issue is, if the master catalog shows a C21499 with ribs or ridges, then this obviously is incorrect, and will be returned.

When you get your books back, and can confirm a C21499 with or without ribs or ridges, that's the answer I need to proceed.

Thanks, George.

Well Dave I just have to ask--trying to help--you asked the question--but you know all the answers or are sure your supplier does--what are we trying to do--why the question? Honestly you must have some doubt!

Submitted by woebegone@mind… on Wed, 01/19/2011 - 19:04

Well, I know about the earlier hose.
Mine is 118011, so definitely later.
When you get your books, let me know.
I only want to have to replace parts once, and get it right the first time.

The outfit that provided the hose knows what they're on about.
And this is specific for a later 2.4L.........

Blood pressure pills....gotta find my blood pressure pills.....

Dave upon further looking there were 2 upper hoses--C9617 from chassis 100001 to 115182 and 125001 to 127125. After that C21499 was used. I looked in the 1967 and 1968 J12 manuals (Master parts lists and interchange) and they do not substitute. Does that help a bit?---There was a change--perhaps you need the other.

Well you can use drawings to prove a lot but in this case I agree. The hose has to have something to allow for torque (perhaps the curve) even for a 2.4. I have loaned my Viart book with all of the factory engine shots-when It comes back I will look

Except, we know we cannot use drawings in a parts manual to "prove" anything.
The supplier has a J.33 that does NOT show the ridges.....
Guy in England says 2.4L do NOT have the ridges, but rather a curve in the hose (as this one has....a dip for the plug wires).

This was part of our discussion, and the supplier checked with the UK branch, and THIS is the hose for a 1964 MK2 2.4L.

Yeah, I'm puzzled.

Dave Jaguar Parts manual J33 plate 56 clearly shows flex joints. May be all the help I can give as I looked at the factory photos and can not clearly see (not that I have a lot of 2.4 engine shots.
