Keep the hole as small as possible. US$1.55 shipped, cant go wrong. Says up to 85c but I have had no issues yet, get 2 just in case

didnt realise they were available that small, i might order one to have a look at it.

This will work no issue, drops in from the filler hole, wires 1st, fish them through the hole you make in the side, tighten, job done. I put a second 0 ring on, one in and one out and to be extra sure I coat it in silicone sealant before I tighten. Leave a few hrs before adding coolant to let it cure. I have done 3 cars without problem.

thats great, i would have gotten one of these and used it instead but your prev photos of an installation was not as neat sounding and i had no idea they where that small. ill use one on my other LR when i make a monitor for that too.

Hi

I added another pair of probes to mine to minimise the possibility of false alarms, but those tiny floats look like a great idea

This is what I've prepared. Just waiting for an opportunity to fit it.

meant to get back to you sooner, to say that yes indeed these floats fit down inside the fill hole of the header tank !
