Coolant leaks out from here

I had this weekend a small leak pretty much in same location as the OP has, showing mostly at the under the front of the engine bellypan. Also a small amount of water dripped little more forward (maybe under the seats location) as I was racing at the track.
Had to retire before last two starts and took the car home driving it... while keeping cabin heater on HOT sertting and selecting only highway roads to allow coolant to stay relateively cool - I have a low temp thermostat.
No leaks on the way home for 110km and temp stayed low.

Opened the bellypan under the engine and found out the leak coming from water temperature sensor, but only when the water was at normal or higher operating temperature and the water pressure was high.

Unless I've missed it, a question or two that haven't been asked: How many miles on the car when you got it? And, to your knowledge, has the WP ever been replaced (by you or the PO)? If not, it's waaaaay overdue.

You do know the low temp therm has absolutely nothing to do with how hot/cool your engine runs, right?

Have you considered snuging up the temp sensor?

Yes, I did get the low temp thermostat to get the water circulation open sooner

I have a new sensor on a way already and will swap it later this week as there is two large water hoses that run right below the motor mount that look like they'll at the end of the life already and I'll swap those as well.

These leaks showed up now as I changed the slightly leaking coolant reservoir last week and the pressure is now staying at the normal level :ah:

So it's not a water pump leak? You've ruled that out?

If that's, by any chance, the original (would seem unlikely, but I think I've heard of them going that long) you should definitely change it out.
