I use a sensor that just pushes between the gills of the rad in the position you choose and it works for me -worth considering ?.

I'd still need to seal the hole and the whole mounting position for whatever I used to seal it still sticks out backward into the alternator.

I've ordered the Fiat rad now but I may try shifting this one sideways enough to clear the alternator as a temporary trial.

Schrödinger's cat - so which one am I ???

I've had some trouble to setup the rad switch. Since I've bolted a water cooled turbo the engine heats much faster, I had to limit to the minimum the flow through the turbo and the bypass (I should have blocked it) in order to make water flow through the rad.
In my previous setup the turbo was oil cooled and there was no bypass, the flow through the rad was certainly higher because the engine temperature where the fan was switching on was 10 degrees below the one I've got now.
Oh, I have the Metro front rad.

Mk1 so inlet/outlet at same end but which is which ???

The fan switch goes into one half of the header but should the radiator be orientated so the switch is at the bottom (where it would point forwards) so be measuring the return temperature, or flip the radiator the other way so it's in the top (pointing backwards) and measuring inlet temperature.

The radiator is 100% symettrical in all respects apart from the fan switch so I can't work it out........


you're absolutely right. the radiator thing really are usable in all aspect. cause this car part help in exhausting the heat to avoid over heating of the engine.
