Reply to "moving coolant temp sender"

Odd readings reportedly result when the sender is installed in a water pump heater hose boss. Possibly from cavitation bubbles. There's nothing wrong with temporarily leaving the sender in the tank, as long as you-
1)- remember the water temp reported on the gauge is probably always reading low
2)- watch the gauge's reading like a hawk, for abnormally low temps as the level drops below the sender. That's your clue to add water.

If the cooling system is completely stock, one problem is a U.S- made radiator cap is shorter than a Euro cap, and won't hold its rated prssure. Worse, water may bypass the small hose and leak out around the cap. The leaking water runs down the tank, across the inner fender and straight into one of the big holes in the lower subframe rail.
