This 3/4" O.D. hose runs from the water pump housing and travels aft on the the valley floor. How does this hose detach?

 

that’s part of the valley hose it’s crimped and steps up to 3/4

you go from the water outlet and replace it whole

 

Thanks, Xalty. Does it twist off from the water supply with smooth metal band remaining attached?

 

Oops, stupid question. Simple spring clamp.

 

The design of the valley hose was changed and improved, the new one should look like the one on the left of the picture:

Thanks, Thomas! What a great improvement! Can't wait to get to that part of the process. I am going to start another thread about welding precautions since I have decided to hire a welder to extract water pump bolt.

Best,

When I replaced mine last August, I had similar ballooning in the large section of that hose, and that was actually the only hose that I saw any problems with, even though I did replace the lot with a complete forklift overhaul. I also broke the plastic reducer/coupler between the large and small sections, which inspires no end of confidence in that design. It was obviously a job to get the intake off for access, but had I assumed that hose was OK simply because all the others I'd handled were actually OK, I would have been in a bad place before too long!

 

Same here...

I decided to tackle the job as a precaution when I bought my car because I had seen the threads about the valley hose when I had been informing myself about the model here in the forum, and I am so glad that I did.

The part that "ballooned" in the picture above at a first glance did not look so bad inside:


But then...:

Hi Steve,

I have seen the new thread, good luck!

Unfortunately I cannot help you there. Although I have a MIG/MAG welding machine, I do not have much practice with it up to now and only use it for "crude" weldings like for leaks in the exhaust, where the beauty of a welding seam is not important.

That might change when I start restoring my my 1974 Fiat 127, but that's another story and I am not even near to starting the job...

Best regards,

 

Yes the under SC hose always fails where it goes from large diameter to small diameter. Everyone I have ever seen. You did not post any part numbers?
AJ89746 is the part number I think.

You might consider an improved valley hose? I just found Swallows makes a Silicon replacement and that should last a lifetime?
Price is reasonable too ($40) and I see they also offer some additional cooling hoses in Silicon and those will also be worth a look!
Silicon Hose

They are in the UK but I regularly order from the UK and while the shipping does add cost since we don't pay VAT it's not too bad.
I really wish this was available when I had to change that hose!

Thanks, Clubairth! You have anticipated a new thread I'm planning to start to be sure I get all the right hoses, gaskets, etc.that I need to start the rebuild. I checked with Barratt on 2 hoses just as a "price check" and they seem high. More later

 

Had heard rumours that some among the Germans thought themselves the original patent holders on the concept of "masochism", so hope you have a plan for fabbing new "A", "B" and "C" pillars?

My '68 124, a mate's Lancia Delta Integrale used the same poor choice of steel, and worse or NO preservative surface treatment in that era that left every "A" pillar around rusted through from the inside out by the middle 1990's.

Irony as it is, the Rooshin Lada & Serbian Yugo copies of FIAT were criticized for use of cheaper hot-rolled steel, yet proved less susceptible to rapid rusting that the genuine Italian models.

 

Well, German cars of the '70s were not that much better, early Golf Mk1 and W123 Mercedes also already started rusting in the catalogue... I have seen some nice examples of that.

Masochist? Not that much, lots of dents, the front fenders need to be replaced and there is some rust a the floor, but the pillars are all sound... and there is quite a personal note to this specific car.
It is part of my life since my mother bought it new, we were living in Italy at the time. In time it was the first car I drove after achieving my driving license, and you can imagine how many memories are connected to it.

I brought it to Germany last year, and we'll see when I will have the time to start the restoration.

Best regards,
Thomas

 

Aye. Removing the interior door handles of my '71 1/2 BMW "Bavaria" to get a new gas water-heater cheaply to my first 'new' 3 br suburban brick home...

Keyed off having removed the interior door handles of Dad's '56 DeSoto hemi ...so my then GF and I didn't bang our heads as much as ....... 'other stuff'.

Main barrier to 'nostalgia' cars is the OTHER fools I share the highway with.

I want JLR's best handling, brakes, and airbags and all that on first-class tires, wouldn't risk my old '59 TR3 on the open roads of today on a bet.

Too many texting-while-driving and "recreationally" drugged or congenitally distracted at the wheel.
