Re: Engine temp?
BEFORE and AFTER I HAD MY RECALL DONE on "Radiator Hose" (not fan) IN NOV '05... my XF as well... runs a tad above the centerline on the temp gauge... especially after a SPIRITED ride, but immediately recoups back to centerline... within a minute.
At the time HDDP convinced me that all XF gauges will not read alike due to the calibration... hence different readings for us all... (as a rule).
