The 4212H Time Sert thread repair kit is designed to be used for the late production 2008 and newer Ford 3 valve heads which use a 12x1.25mm taper seat spark plug. It is also used on some Ford Fusion and Escapes that have a 1.5 Liter engine and use M12x1.25 spark plugs. Partial listing below. *Make sure you have M12x1.25 and it's a first time repair.

Question: I have a 2009 f150 4.6 3 valve. I think I need the 4212H time sert. I have watched their video but can't figure out how to insure I stop the cutting edge at 1/4 because I can't see down in the spark plug well. Do you have any tips? Also does piston down valves closed need to be performed when doing the 4.6 3 valve?

Answer: You could mark the tap with a crayon or wrap with paper tape and check frequently by removing and seeing how far down it had reached. The valves do need to be closed and piston down enough not to be hit by tooling. An easier way to determine valves are closed without removing the valve cover is to use the 389-4000 Cylinder Leak Tester.
