What is the original source of the expansion/header tank on the 350i/390SE and I think 400SE.?


Mine is a 390SE and wondering where does it originate, I think Ford from memory but can't find previous posts telling exactly what Ford?

Cheers
Steve.

Are you wanting it to remain 'original' or are you open to 'improvements'?

Yes; the reason I ask is that I am looking for something that fits the same but little more bling!

Plenty of alloy tanks on evilbay with the '15lb' cap. I think its 15lb.

You could take the opportunity to simplify the plumbing - reverting to the arrangement used in the SD1. Needs some plumbing peices but not that expensive and fairly simple. Removes the potential air lock induced with TVRs arrangement along with a couple of pipe runs.

Mark has a very shiny one, which I'm sure he'll post up at some point....

Pressure rating is nominally 15psi however I'm running 16 psi. There are several companies who make and sell shiny Capri expansion tanks, as below. It is the 2.8i Capri model it's off. They do come up on evilbay regularly and go for £30 to £40. There is one on at the moment but at £75 for a tatty looking thing!

Company is nothing to do with me (Big Al)

OR

Get rid of the Swan neck thing and the expansion tank and modify to early Griff / Chim spec

If you have power steering you will need to modify the Griff / Chim tank

Pics below (nb the little pipe off the top of the rad can be just blocked off)

Check out the pics of engines on the early chims / griffs and you will get the idea. It’s much neater

So,
that looks like a sealed system now ?

where would 'overheating' water go ??

Is the blue cap a pressure sensitive one (as per the old expansion tank one) ?

You ditch all the old stuff in your photo in exchange for the new set up ??

Blue cap is a pressure release just like the old metal ones.

Sealed system worth consideration Glenn, presume any release from cap just blows out and down the cylinder as no pipe?

Worked on my SEAC perfectly and on all the early chims and griffs (as I stole that design)

The blue cap let’s fluid out if too much pressure. Once bleed and left to cool, the silver tank is about half full so has plenty of “expansion” capacity

As for my old stuff, it’s on the shelf
