yes.....

My old S4s only had one filler for both the cooling & chargecooler systems. ☺

Hmm... it's a dual tank set-up with two separate pressure cap.

Not on the later cars, Mike.

S4s and GT3 use a single Peugeot 205 header tank that looks like a cow’s udder, which has a hose connection to/from the top of the charge cooler itself. This is presumably to accommodate expansion. The systems are therefore not separate.

Oops - excuse my ignorance.  I'll stick to comments on the V8 🙂

Metro,

Have you repaired your radiator tray yet?

I’ve done mine, I just cut out the old parts ,made some stainless brackets and fibre glassed them in. Came our well. 

Nearly in a position to reinstall. Just waiting on some more replacement snapped off fasteners!!

One tip. The air con pipes that connect to the condensers were semi seized and hard to get off. I didn’t want to wreck the threads on the new condensers. So I made up some thread chasers to clean out the female threads on the connecting pipe work . I purchased some steel pneumatic adaptors cheap online. A 5/8 and a 3/4 UNF, I then cut across the threads at 90 deg’s to make some slots . I screwed these in and out of the hose ends to clean the threads. They go on by hand now.👍

Soak the pipe ends in caustic soda / hot water bath and ensure you are outside and at a safe distance. It will dissolve completely the aluminium in about 15-20 mins

Barry that would be a lot easier But! the threads are attached to an aluminium pipe that you need to keep! 2nd photo.

Pipe ends are brass or steel - they don’t dissolve 👍

Unless they are different from my S4s.

Hi Andy, unfortunately I haven’t had chance to look at it yet due to stripping the suspension off the car.  I got replacement support brackets from SJ to fit in but I’m not sure if I’m just going to buy a new tray assembly.  I’m terrible at fibreglassing and by the time I’ve bought a kit and sanding bits and the time it would take me I might just bite the bullet and get a new one.  
 

you have made a fab job of your repair 👍🏻
