Sorry didn't remember that the rad was leaking.
Can't see the point of replacing a thermostat, unless you test them properly (not just dropping them in hot water) but heating water so you see the stat open and then cool so the stat closes. Have recently found brand new stats failing and not opening at the right temperature or not fully opening.
As for temp sensors, am in the wonderful world of how can something either work correctly or fail completely. Seems rarely to do that, so the idea is to check the resistance of the sender at ambient then at operating temp. If you have the resistance range should be able to give you an idea of the faulty part.
If it makes you feel better, currently trying to source an OEM temp sender but the OEM manufacturer no longer supplies the auto manufacturer. So trying workout with other auto manufacturer still use them.

There was logic, the rad was leaking, coinciding with the original reading hot on the dial. Thought that was the issue, so swapped the rad for a replacement part. Did the stat at the same time as preventative maintainance.
Then it didn't improve, so changed the sensors both sensors were genuine Mazda parts.
