    Maybe just use the 4a one and either have the heater lines welded up or covered up with either hose or some glued on plates.

    In the one youve linked (the nice looking one) there is also a vac looking fitting which i assume is to allow air to be bled. Youll also need to take that into consideration when finding a suitable mounting position.

    Lol. You're actually trying to do what i have been looking at recently.

    I think the anodised one has overflow outlets so that when thermostat is closed it can circulate water back up to the inline piece through the motor...

    I was looking at getting two thermostat housings with identical bolt spacings and getting a piece of pipe lathed up to suit and bolt it together. But the overflow outlet is probably required, otherwise there is nowhere for the pressure to go...

    Is this for the upper hose, usually the engine's outlet and the radiator's input, or is it connected to the engine's inlet at the WP, that connection from the radiators outlet, the lower hose to the pump?
    One may work with enough heat conducted and a hole drilled in the therm., and if it's in the lower hose & never getting any hot coolant & even if drilled, it'll never get hot enough to open. The thermostat needs circulation from a positive pressure source of hot coolant from around the exhaust ports & combustion chambers, when it's on the lower/inlet hose.

    Pressure, an overflow/recovery system???

    you're right. it should be in the top hose, with a bypass back to circulate hot water through the motor till thermostat opens...

    Some peugeots simply have the thermostat stuck in the radiator hose - there is no housing. Look at a thermo catalogue or possibbly you could make something up to slide inside the hose.

    thats pretty much what i have done here, i have an sv21 thermostat housing from supercrap, took off the 4a top housing identical to the sv21 part (pure luck that one) cut the flange from the 4a bottom housing to use as a spacer, drilled out the holes on the two 4a parts then tapped a M10x1.25 in the sv21 part, drilled a hole in the thermostat, bit of gasket goo and its all together

    and this will sit in the top hose

    thanks for everyones help +rep for all

    I was trying to say that it can be mounted anywhere, engine inlet or outlet, and that it needs flow/circulation, because even on the engine outlet there won't be enough heat conducted thru the water if it is sitting still, without a major hole drilled through it.

    I was thinking more about this recently as I am doing some changes to my cooling system -

    In the picture you put at the top (the anodised stuff)[Skiddz -Where did you get the picture from? Who sells them?], The one that would contain thermostat would flow water through the brass barb fitting to the bottome radiator hose where it would continue to circulate until the thermostat opened and then water would pass through the top hose and then the radiator... However, with the bypass outlet(brass barb), some hot water would continue to flow through the engine. I suspect that because of the placement of the bypass barb, when the thermostat opens the flow going through to the top hose would limit the amount going through the bypass to the bottom hose. Is this correct? I'm no expert on fluid dynamics.

    Does anyone have any thoughts to make this work effectively. If there was suck thing as a thermostat that closed i could run that in line with the bypass to close at a slightly higher temp than the main one! But, I don't think they exist....
