I replaced a burned-out starter for a Ford 1.9L, and the replacement has always made a slight, brief grinding sound when the engine is cold and the weather is cool. I've tried shifting it slightly around its mounting bolts, but it doesn't move much, and it doesn't seem to help.
I'd rather not exchange this starter under warranty because I'll get a rebuilt, and this starter was brand new when I got it. So I'm thinking of taking it apart and lubing its overrun clutch/Bendix gear, but do I have to use a special grease, such as something that doesn't get too thick in the cold?
