I have had a problem with the fan had lost low speed, Now fan comes on after a short trip and stops on ages after car switched off. I was using phone earlier so stopped at side of road, Within 5 minutes car temp had maxed out. I checked dipstick and oil looked ok (at the moment). let cool down until normal temp drover about 1/4 mile home and temp started to rise again.
And yes before anybody says I told you so .......... I know I was warned.
