Hello all;ok I have the wacko flashing temp gauge syndrome which magically
showed up  after a coolant flush...and replacement the coolant used was
Pentofrost SF....My guess its either and air pocket or a fill level issue.

I have read through allot of the archives and know the sensor and gauge are
working properly,also the grounds are clean as a new babies behind etc. Am
I over looking something with the fix? Any words of wisdom from the forum
here is greatly appreciated.

Thanks DS
