1999 SW1
Default 19999 SW1 temp gauge behaving oddly after radiator replacement

First, I bought the car used about 3 months ago and it didn't come with maintenance records. It has 212K miles. After a few weeks, it started losing a little coolant. There was a small leak on the plastic part of the radiator that someone had tried to patch with epoxy and the patch wasn't holding. This past Saturday, that trickle became a massive leak.

I bought a new radiator and upper/lower hoses and installed them Monday. Leak at the radiator is fixed. I've done this before, so I knew to expect some trapped air in the cooling system to take a little time to get out to the recovery tank. I've added a little coolant 2-3 times because of this. there is a sort of gurgling/hissing sound coming from the coolant recovery tank but I can't tell for sure if there is a leak there.

Before the repair, (and after replacing the ECTS), the temperature gauge was consistently at 1/4 any time that the engine was warmed up. Now, the gauge goes up to 1/2 and sometimes a little over 1/2.

I forgot (silly me!) to replace the thermostat while I had the hoses off. Maybe I should have done that - and maybe I will need to? I'll have to drain and replace most of the coolant to replace the thermostat, so I need to know whether this is a necessary repair.

Mostly, I want to be sure that the car isn't running too hot.

any help would be appreciated!

Thanks in advance.
