In line thermostat

Post by ranald » Sun Nov 11, 2018 8:30 am

Hello, I’m back to thinking about fitting a thermostat into the cooling system of my Lanchester 15/18. Does anyone know where i can buy a housing / thermostat suitable for fitting if i were to cut a section out from the top hose?
This looks like the sort of thing but unfortunately is not a UK seller:

I think Burton do them for fords but can be used on anything. Kenlow and other electric fan suppliers also do kits with all the bits included.
Colin,

The Meziere fitting is available (quite expensively) from Amazon UK and from H-Tune, also in the UK.

There's a much cheaper Land Rover option available here, although it looks as if the actual 'stat is sealed in.

Thanks both for your input. I've looked further and come up with another one.

Seems a reasonable price and is manufactured in the UK. They give a 74 and 88 degree c choice. 74 degrees would seem to be a sensible setting.

Maybe this is a daft question. If i was to fit a thermostat in the top hose and had to drain the system, how would i refill as of course the thermostat would be closed. i know water would enter through the bottom hose but the top hose wouldn’t be allowing water through or air out.

Run the engine with the coolant cap off and listen to the gurgling! There may be trapped air in the heater circuit so loosen a pipe there until coolant comes out. Generally, there's no need to do anything as running the engine clears air and coolant as it comes up through the radiator. Check the coolant level after the first few runs as air is got rid of because, as you say, some air will be trapped behind the thermostat but this will get cleared when the thermostat opens..

Some people recommend parking the car on a hill or on stands with the front up the hill so that the expansion tank is higher than the pipes at the back of the engine and air goes forward to the tank, but I've never needed to do that.

Fit a thermostat with an air bleed hole - or 'jiggle valve' as Ford calls it. This allows any air trapped in the engine cooling system to bleed through to the rad. If a bleed hole type is not available you can easily drill a small hole in the 'stat yourself.

Ah, I see. Thanks.
John, No need to worry about air trapped in a heater circuit as the 15/18 doesn't have such luxuries! I was out yesterday and resorted to a blanket and gloves. All the best, Ranald
