Water Pump

I think the water (and maybe oil) temperatures could be too low for too long. Maybe not a big issue in your climate, but in colder areas you wouldn't have any (or enough) heat. Engine oil and coolant temps. too low probably isn't good for the engine just like too hot isn't ideal.

Removing the T stat makes the engine run HOTTER.. The coolant goes through the radiators too quickly to cool.
