I'm helping my nephew work on his 2002 Escape with a 3.0 engine- he swears it uses standard (inch or imperial) threaded fasteners, but it sure looks all metric to me. Can anyone confirm or deny this? I was a professional car mechanic for many years way back and do remember when American cars began making the transition, but it sure makes sense to me that they would be all metric by now.

Sure think they are all metric. Easy to tell just by the marking on the head of the bolts. SAE have the lines, 3 or 6 usually while the metric have numbers like 8.3 to tell their grade.

That vehicle is all metric. There ain't an SAE thread on that car.

all metric, however....
8mm = 5/16
11.1mm = 7/16
12.7mm = 1/2
19mm = 3/4

Yes and Ford uses in-between sizes as opposed to Japanese vehicles. So if Japanese use 10, 12, 14, 16, Ford uses 9, 11, 13, 15.

All large sizes can be english but 6 point works best.

Some of you are talking about what size socket works, not the thread - big difference.

Oh my, here is the OP asking about threads.

Some of the threads are close enough to go into the other style and not cross, but they also never truly get tight.

Some vehicles did carry SAE threads for a long time, but the last place Ford used them was in the block of the 351 for accessory bracket bolts, and IIRC 97 or 98 was the last year for that engine. It was the big gas engine for the F-250 LD/F-150 7700 trucks.

The 5.0's carried on with the SAE till 2001 but only on engine and few pre-existing assemblys. Mustang finally switched to metric wheel studs in '15'.
