Fitting header tank - Esprit Turbo

[martynw]

This seems such a simple question but I am stumped. I've got a 1985 Turbo model, but with the additional plastic expansion tank and other cooling mods set out in Service Bulletin 1987/26 (see below).

From the look of the header tank, it bolts to the side of the engine bay somewhere. However I can't find any holes in the body or engine surround. I'm assuming it should end up somewhere near the front of the arch just behind the petrol tank (see photo) but can't see how. Am I missing a bracket or got completely the wrong end of the stick?

Also, if anyone has a full copy of S/B 1987/26 and could upload it or provide a link it would be appreciated.  I struggle to find any of the Service Bulletins online - maybe we should start a thread where people upload scans of any they have.

Right side of bay, right at the back, just behind the air box.  Coincidentally I'm doing one at this very moment!

Any chance of a photo? Do I need to drill holes in the engine bay sidewall? And add spacers to provide clearance from the top edge? 

[martynw]

No worries - I've just found this. All makes sense now.

Never again will I buy a car in a series of boxes. Probably.

Well, at least you won't have to drill any holes. By the way, check the condition of the header tank. They are prone to getting pinholes from corrosion and are often a terrible rusty mess inside. I just changed my original tank for an aluminium one for that reason.

Mine looked pretty good, plus I have given it a good coating inside with POR15 tank sealer. I'd prefer to keep the original and it is a fairly easy swap if it goes wrong, so for now I'll chance it.

Still haven't found that arch insert on any of the parts lists, which is why I was so confused.

And just to be different and difficult, the USA '85 Turbo has it attached to the engine bulkhead behind the electrics.  You'd think it would have been easier to standardize across the line for a small manufacturer, but differences abound.

My S3 has a bracket underneath the tank that bolts down onto the chassis rail. The benefit of hand built cars is they can all be different I suppose.
