I think 186 F is too cold for a standard E46??

Most stats fail on the cold side in these cars anyway.

The problem is the temp gauge is buffered and sits directly at 12 o'clock over a 50F range so it is hard to tell when the stat is bad.

I will check and see what the standard engine temp should be.
