From: Ian on 27 May 2007 17:12 Dear Folks, The thermostat housing on a friends SP250 broke in two last week - on examination it had clearly been cracking for a long time. They are currently out of stock at every supplier he has tried so I am wondering if anyone here could suggest anything which would fit. There are easy, medium and hard bits to the specification ... Easy: It's a bog standard thermostat - same pattern/size as a Herald, for example. Round, and a shade under 2" diameter (going by the gasket) Medium: Two 5/16 UNF fixing bolts, 3" apart (so the gasket also looks like a Herald one, just a bit bigger Hard: The outlet is 1 1/2" diameter and comes straight out the top - ie along the same axis as the bolts, and not out to the side. There is a slight offset, but not worth worrying about as the radiator can be shimmed to eliminate the need. If this sounds vaguely familiar I'd be grateful for any hints about an alternative part which might fit. Ian

We've though of that but a) it's light alloy, and pretty manky from the look of the fracture surfaces and b) it comes out of the engine sideways (the flange is vertical) and is joined to the radiator by two very short hoses with the expansion tank in between, so although the stresses may not be very high, it'll see a lot of cycles as the engine moves relative to the chassis/radiator. Last resort at the moment is fabrication, but it would be vexing to go to that trouble and then find that the housing from a Sprogget and Walmsley was a direct swap and readily available ... Ian

Next is David Manners in the UK - he bought a windscreen from him. My friend also needs a set of hood sticks for his car, among many other things...?

Not an SP250 thermostat housing to be seen! And yes, everything is there, just about. A Well Known Journalist is well on the way to building an entire Dart from eBay bits ... > Next is > David Manners in the UK - he bought a windscreen from him. Out of stock at the moment. Ian
