Hi,
My Moss Herald 13/60 has an electric fan with a manual switch on the dashboard.
I would like to fit a temperature controlled switch  (due mainly to not trusting myself to keep a proper eye on the gauge!   )
Does the engine have a location/mounting point for this or do I need an "in hose line" version.
Any advice on which type, on & off temperatures, etc. would be greatly appreciated.  
Thanks.

Hi, I think I can help with some of your questions. Theres no mounting point as standard for a sensor but you have several options as how to measure the temperature:

One is as you mention the in-hose type which operates an adjustable mechanical thermostat. This is probably the cheapest option but can leak.

There's an air temperature sensor that is secured in the fins of the radiator and which operates an adjustable electronic relay to control the fan. Its more expensive but the easiest method.

You can mount an adaptor in the middle of a hose (cutting it in half and clamping each each to the adaptor) which will accept a temperature switch to operate a relay for the fan. I dont think this type is adjustable so you just get the temperature switch with the correct operating range all of which will cost some where between the other options but is more hassle.

With the setting of the adjustable systems I believe the best is to install everything and then set it up when the engine is up to temperature....

The Revotec sensor fits in the top or bottom hose and is fully adjustable. I have mine in the bottom hose of my 13/60 and it works fine. Cheers, Dave.

Thanks for that info.
I don't fancy a leaking water system so that insert type is out of the running!

Any idea which on & off temps. the 13/60 would need?

Stick something like this in your bottom hose.




Google along the lines of "radiator hose sensor pipe" to find one to suit you.


I'd use something along the lines of a 82-72 switch. It'll only come on when the radiator is passing water at the same temperature as your thermostat and allows a 10 degree drop before it enters the engine.


Acclaim - fully working and on the road
13/60 Herald - mx5 powered and other such fun things, legal enough...
Mk1 2000 - it's still alive, just sleeping
Expert 815d - the slug

If in doubt, do up until you hear the crack and then go another 1/4 turn to ensure tightness.

Speak for yourself Ferny, I'd rather not thanks!



On my 2000 I used the 'bulb in hose' type and that worked fine. I just put some silicon sealant inside the hose, ensuring it didn't get into the water supply of course.

However, after the electric fan died after less than 2000 miles (it died on RBRR), I have decided to go back to the standard mechanical fan, which worked fine for many thousands of miles and about 50 odd years...

I always use a sensor like that above, screwed into a boss set into the header tank of the radiator. Good car radiator repair companies will fit a boss for small money.

Don't like the type that go into top hose as the Kenlowe or the type Pete shows.

On my GT6 I have it wired so that I can manually over-ride.

Anybody used one of the poke-in-the-radiator-fin type sensors I mentioned previously? It could even be done on the very cheap with one of these:

I have a poke-in-the-fin type fitted on Tessa, having previously had one on the Stag. Both were simple DIY jobs of less complexity than that eBay item, although not the really minimal op-amp and FET design; I used a PIC and provided variable speed and after-run. They work fine as long as the sensor stays in place.

I used Car Builder Solutions & went for one of these with the 82-72 switch & fitted it to the bottom rad. hose complete with a relay -   it works a treat..!   I will put an LED marker light in the dash to show me that the fan is on....thanks for the advice folks.
