Somedays it takes considerable time for the temp. to reach correct operating temp. Somedays it gets there within a mile from home. Then somedays while driving normal it will just drop to a couple of ticks to the left of normal and then come back to normal with no change in speed or conditions. I am still running the stock temp. sensor on the 225.

Any suggestions????

I have a green sensor, but no o-ring.

Is it OK to reuse the existing O-ring when I changeout to the green sensor?

never reuse an O-ring...imo. At the price of a whole new sensor at 6$ or so...its worth it.
As far as the gauge moving. Setup your AC to monitor the engine temp and see if its running cool...which more than likely is not.
<push recirc button and up arrow together...rotate temp control till you see 49C..then hit recirc again> this is your engine temp.
More than likely, it is the sensor...could also be the precursor to a cluster problem....IMO.

and when monitoring block 49, what is the danger temp?!

TTinCT

120 Cel is about 250...that is too hot.....IMO

hAUDIni

cool, couldn't remember what Schwing had said. 120 it be.
