coolant level drop is odd. other 2 are normal

 

The "metal contraption" you are pointing at looks like the ECU - and yes it does wiggle around. The radiator is not bolted in, it is held by supports which allow a little bit of play but it is in there securely don't worry.

There are alot of threads on the low coolant light coming on. Do a search on them, there are way too many theories to list them all here.

 

My coolant level dropped a bit within the first 3,000 miles , added dexcool , never dropped again. Musta had some air in it that worked it's way out .

 

Well thanks a lot guys, thats very helpful. Yea, I saw a lot of coolant threads.
