Does anyone know where one might find a replacement for this?
Mine is looking very rusty. It would be nice to replace with a stainless version if available.
I'm talking about the pipe which crosses the front of the engine, with the radiator cap attached.

 

I had mine sandblasted and welded. After that painted. All fine now.

 

Stainless were available down here many years ago.

JagDAim in Melbourne.
H & H Prestige Spares in Melbourne.

These are where I got them form waaaaaaay back.

 

Cathouse Spares in Australia was the name of the Co. that sold a stainless crossover pipe & overflow tank. I don't know if their still around anymore though. My stock pipe & tank never had any issues after 25yrs. I do remember the SS pipe & tank + S&H were very expensive. Personally I'd just replace mine with OEM. That would give me another 25yrs

If only, Lawrence, they at NLA. For the OP, I think that the best thing is to get a decent one from a breaker and then rust protect it as well as possible. The Great Palm book mentions it is possible to fabricate one out of copper tube and fittings, but it does need expert brazing ability.

Our community is fortunate, where else would q have access to a free manual all about your favourite car that's 700 odd pages long.

They are still available but they are over here and not cheap.

It's missing a few parts. One connector (bleed hose) and the top cap to fill...

 

That is a pre HE Baxtor, no good to most of us!

I bought a SS xover and tank from Bob at Cathouse a couple of years ago. I know he wanted to retire and had the business on the market, but last time I spoke to him he was still trading.

 

His business name changed to Jag services. The HE pipe still shows up on Ebay but is marked out of stock. I also have tank and pipe of his but would probably fabricate using copper fittings and pipe if l needed another.

 

You are right about the name change but the web site is still Cathouse and the phone numbers were correct last time I spoke to Bob about 6 months ago.

You need to be careful if using copper pipe. If your coolant has any ionic content (ie use tap water) then the aluminium will be susceptible to galvanic corrosion.

 

Is this the case only if the aluminum and copper are in physical contact, or is the contact made by the coolant? I ask because, to install a aftermarket aluminum radiator intended for V8 conversions, I made a crossover and tee pipe from copper. It isn't actually touching anything but the hoses and mounting clamps though. That type of corrosion never even crossed my mind.

What would corrode, the copper or aluminum? and would it be pretty evenly distributed throughout engine and radiator? I've had aluminum corrode where it was in contact with steel, not submerged in liquid though.

I did use tap water, our water is not very high in dissolved minerals though not near the level of distilled or d-i water though, what influence will this have? It seems to me that even distilled water would pick up some contaminants after circulating for a while that would be "ionic"

Thanks, Eric

 

My understanding is IF the coolant spec is kept right up to spec, no issues.

SOOOOOO, we all keep the coolant spec "spot on", do we not?????.

NO slack maintaining in here I would have thought, haha.

The original radiator was Copper/Brass, the heater core Aluminium, the engine alloy, the water pump impellor cast iron, the header tank crappy tin, the vent pipes on top of the radiator "Bundy tube", so best of luck working the science out there.

 

Now I understand why so much garbage in the cooling system.
Galvanic CORROSION!

 

Possibly, additionally advice given by Jaguar for servicing was to use a product called Barr's leak as a part of regular service to coolant system.
Many people including me think that this shouldn't be used, but if it has been used previously then unless flushed thoroughly then sediment from use of the product may circulate the cooling system's myriad of passages!

 

Grant is right on keep the coolant up to snuff and copper pipe will be ok.

As for the brass and copper radiators the copper is tinned so this will prevent the corrosion issue to some extent.

We had a huge issue with galvanic corrosion on aluminium cases with a copper fitting, but this was only a major issue in NZ where our instruments were near the sea.

 

Thanks everyone. I have some por15 sitting around from a while ago, so once I have it removed will give it a de-rust & coat it in that if it's still structurally sound.

 

That's what I did.

On first glance my crossover pipe looked ready for the scrapyard but on closer inspection it was in better shape than I thought, and was still perfectly serviceable. It's a fairly stout piece. The innards were clean as a whistle

A good scraping and sanding and a couple coats of POR15. Blurry cell phone pic below

That might work por15 is brilliant stuff and tuff as. Give it a try.

Also por15 have a tank sealer, this might work for the inside of the header tank and pipe.
