No, it was one that I purchased on the bay. I think the same item mentioned by Delbourt. Seems to be good value.

Hi that's the one I fitted, seems to be fine and good value.

Any thread that catches my interest usually has some technical bent, as I’m an inveterate fiddler & have rarely be able to find the “box” to think in, it can lurch to any point of a technical compass.
Any contributor whose thoughts chime with mine has my undivided attention; if you care to look back at some of the interplay between Cobber & myself, much has gone so off the original topic, that it’s origins couldn’t be discerned other than by divination.
Here’s another lurch sideways.
I’m staying a few miles from Trophy cars, on the Great North Road, I might have a walk up later, if I go on my own I might come away with another car!
Go with the flow? Or swim against it?

Bruce's low coolant alarms are really reccommended.
I have modified my 2nd one by adding a delay circuit to delete the test beep on startup and also avoid it triggering under hard cornering conditions. It will only sound the alarm if the sensor reads a low level for more than 10 seconds.
