Guys,

After your help.

On the 400 / 450 SE SEAC - where does the pipe from the bottom of the expansion tank go - is it the top of the rad ?

The over flow pipe from the swan neck - does it go to the expansion tank or the overflow tank ?

The remaining pipe on the front of the expansion tank - where does it go to ?

Useful picture .. clearly shows bottom of expansion to rad (top) .. great..

Also shows swan neck overflow to pressurised header tank (great)

but the front pipe of the header tank .. now that just seems to end in thin air ?

Hi Mate..Had a look through the book but cant find any more pics..Surely it must hook up to your heater matrix somewhere?..It looks like its going into the bulkhead in the pic..Hopefully someone will be along to confirm soon..Cheers..Ziga

Yes - I'm thinking heater matrix feed or return pipe.. but as you can see, it's all a bit non standard and I'm just trying to replicate what TVR did with the wedge water system.

The bottom on on mine goes to the top right of the rad looking at it from the back.

The pipe close to the filler cap went to the swan neck

The pipe lower down came off some where from the manifolds area.... I think it was the top of the pump perhaps? Have to dig out the car to check but I have a new ally tank now.


I have a piccy of a 350 setup here


Edit. Mine was a mad plumbers convention bastid child before the rebuild though so not original me thinks.

Edit 2. Thinking about it my pipe that went to the swan neck would have been above the air in the main tank when cold.

Trust you to dig up a gem.

TVR original spec - 350i water flow diagram written on old bog paper.

Proper Blackpool engineering biggrin

Cannot claim the credit here. Been floating around me hard drive for a few years.

I think Jeff's pic pretty well resembles how my 390 was set up before I bypassed the throttle body heater. The T-piece shown going into the heater hose is just above the thermostat housing on my car - it was a plastic item that didn't like the heat and snapped; I replaced it with a union of my own creation (it's an unequal T due to the hose diameters differing, maybe you could use a 22-15mm copper fitting).

I will check my SEAC over the weekend to check were the pipes go etc. I know that they are not the same as a 350i (either early or late)

Did not mean to infer that it is the same. Mine are somewhat different, just for a bit of info on what may be done.

Mine is somewhat simpler than when I first bought it.

Your diagram helped me with my 350i when I needed it so thanks for that!

The problem is typical TVR and there owners!

People and TVR have change things if they think it works better nono (May not and in fact most times doesn't) and they don't recorded the changes!

So what you get is different views and ideas etc!

Take the "Bible" nononono the water diragram is a basic view from a parts list. But it doesn't cover all the models!

Personally keep it original, that's how it was made so (the old saying) "if it's not broke leave it alone"
This applies to most things on the car! As when you come to part with your pride and joy if it's original you will get a better price!!!!!! teacher

Ah, to clarify, mine was a transplant and a poor one at that as was no where near original in its form when I bought it. It was on the slippery slope to doom when it went into the garage for the rebuild due to a poor job not in my ownership. It came out somewhat simpler. When it went in there were joins between this pipe and that pipe and pipes going here there and everywhere and it looked like an accident in the yard at polypipe. Given the symptoms I think there were attempts to cure the issue but the cause was much more serious.


Edit.

Cobblers. Not seeing the point am I. Ignore me, god knows what mine is.

There's no such thing as a standard Wedge. The OP's post shows this admirably.
