I put one of these on my landcruiser diesel today and it seems to work well.
Very easy install and easy to adjust temperature alarm.

I been driving around watching the temp go up and down in 1 st gear low range in thick sand with an ambient temp of about 35c but couldnt get the coolant temp at the outlet to go over 91C
