XE header tank.....look Ned!!!
For anybody building an XE powered 7 who wants a minimal plumbing setup, get on the phone to my mate Clive at Custom Solutions, this is a really neat
setup and eliminates a fair bit of plumbing, whilst adding a bit of volume to the system and accounting neatly for the step between the thermostat
outlet and the polo rad top hose connection.
The bleed will go round to the inlet manifold top connection and yes it will have hose clips!!!

just found that clive has it on his website too, before I paid and ran off with it!
Oh yes, meant to say, the outlet is tangential too to help a tad with de-aeration and again to line the hoses up perfectly. It all fits under very low
(i.e. stuart taylor) bodywork too.
PPPS the welding is NOT done any justice in the pics due to reflections! It is totally flawless!!!

That does look extremely nice! Not exactly Locost, but an excellent price considering the amount of work that's obviously been invested. I
think Clive will be getting order from me once I have my engine in the chassis.

Just to big up Clive from another direction - for a more traditional header tank for an XE (don't have the design flair of NS Dev!) Clive has
been great about replying to emails and me changing my mind as the wind blows....
NS - by the way - an this might be a completely dumb qustion, but which is the connection from the manifold - I've never used an XE before and
didn't have the chance to see it in its original car!

well it looks ok i suppose 
but i've already gone for lots of pipework to a conventional header tank on the scuttle!
Chris, on the front of the manifold there are two openings in the head infront of no1 where you can put a bleed from that side of the head to stop air
pockets forming in the head. I've used one of these to relocate my temp sensor to!
Ned.
ps here is a pic of where i've put the temp sensor and the machined bit above it at a slight angle can also be drilled for a bleed.

Not a dumb question at all, the bleed comes from the inlet manifold just above the alternator top mounting (the adjuster mount)
If you look at the area round where the mount bolts on you should see an 8mm hose barb which is the top bleed connection.
Most of the aftermarket manifolds for throttle bodies or carbs have a tapping for this bleed. (usually 1/8 npt)
Clive mentioned your tank while I was there, you'll be pleased with it!

Ahh!!
Gotcha! I thought it was - when using the original inlet plenum etc it goes via the air inlet manifold for some reason, that's what had me
fooled - by the way, sorry about the thread hijack!
Clive is VERY helpful and comes highly recommended from me !

try meeting the bloke - he seemed to spend more time dealing with customers than he did making stuff. The bit that got me was he didn't seem to
mind. He's just a really nice chap ........ who's too blooming fussy about quality (stuff he's thrown i'd be more than happy
with)

Just a couple of observations:
Is this intended to replace the sealed expansion tank (not overflow via rad cap type)?
If so then is there enough air space to allow for the extra coolant volume due to temperature expansion?
Is there any other mounting than the tab on the side only it looks like it might suffer from vibration?
Cheers,
Colin

Yep, sealed expansion tank setup, don't know on the expansion volume but it should be sufficient...............anybody know what the expansion
air volume should be???? guesswork has always worked for me in the past!!
(trying to think how much the level typically rises on my road car, not more than a few mm in the (fairly large admittedly) sierra header tank)
Re the mounting, there is a tab on the base of the tank too bolted to a rivnut on the chassis, not in place in the photos as we werent sure exactly
where it would go until the tank was in place. (price includes a pair of brackets to whatever requirements exist in whatever the application may be.
Obviously the relative hose heights will differ from one application to another as well)

A quick calculation gives around 50cc expansion requirement for a system containing 6 litres of coolant, so with a 14 lb cap that would need the same
volume of air, not allowing for air temp rise, so to be safe I guess 120 to 150cc would be ballpark, think there's around that above the top 1
1/4" connection on the tank, so should be ok!

my only concern would be that if you start to loose water for whatever reason there isn't much (any) head of water in the system so you'd
need to notice the temp going up pretty quick before it starts cooking.
at least with a conventional system i have the water in the pipes upto the header tank on the scuttle and the volume of water in the header tank.
if i was to design one like that i think i'd want the spare water above the hose connections rather than below it - space permitting (or maybe
use a wider diameter pot)
I know with regular checks (ie every time you run/drive the car anyway i expect/would hope) then its not really likely to be a problem and it is a
very neat and tidy solution.
Ned.
ps where does the overflow from the tank via the cap go/vent to ? mine has a pipe on the side of the filler neck for the cap to vent out of.

Won't say it wasn't a concern but thinking about it I ran my manta with the XE in with no header tank at all, just the radiator top tank
with the bleed hose barb soldered into it, and had no probs with that.
