Default Cooling

Well, I've been a little remiss in not updating my diary so i'll try and catch up over the next few days.
First 'catch-up' update is about the cooling system which I tackled back in August.

I'm using an alloy radiator designed for a Ford Escort RS2000 Mk2. It's the same size as the one I used in my Marlin Sportster so i know it works well with the BMW engine.

The Escort radiator fits remarkably well behind the Sabre's nose.

Because I'm fitting a straight 6 BMW engine I had to move the radiator support frame forward by about 65mm. The support frame and brackets are standard parts supplied by Royale. I've put spacer tubes between the radiator support frame and the original chassis mounting tabs. Further strengthening tabs were be fitted but not shown here.

After extensive internet searching I eventually found these really neat grommets on ebay.

Despite mounting the radiator much further forward than John Barlow designed it's still possible to reach and remove the radiator cap.

13" Comex fan, supplied by Revotec, mounted on the back of the radiator.

Previously I've used those plastic tie wrap type mounts which damage the radiator so this time I used the Revotec supplied mounting brackets.

I've chosen this MG Rover 25 ZR coolant header tank (PCF000161). Here I'm lining it up to check clearance with the engine and bonnet top represented by the piece of wood. (You can tell it's summer as I've got my jumper and gloves on :-) )

And that's about as far as I got with the cooling system. Pipework etc will be completed on the final assembly following painting and fitting of the central body tub.

That's all for now, more updates to follow soon.....
