#1 of 16 Different Oil Filters: 4.0L V6 SOHC; Explorer & Ranger
Oct 17, 2002 (7:35 am)
I have a 2000 Explorer & 2001 Ranger both are 4X4s and have the same engine & transmission.
Neither have an oil cooler. The filters mount in the same location and at the same angle, and yet they require an FL1A & FL820S respectively.
I asked the dealership and Ford's Customer Service Center and neither knew the answer nor wanted to pursue it any further.
Is there anyone out there who knows???
#2 of 16 Diff filters

No, But as the owner of a 2002 Explorer with the 4.0 engine (uses the FL820S), I'd like to know, too.

You might check and see if the clearances during chassis and engine motion prevent the Explorer from using the big filter that is used on the Ranger. I have a 2002 Mercury Mountaineer Premiere (and I love it!) with the 4.6L V8. It uses the smaller filter as well.

The FL1A & FL820S are the SAME size on the Explorer & Ranger.
Also, does anybody know who manufactures Motorcraft oil filters... Purolator, Fram???

The FL1A is the common oil filter found on most fords. I don't know anything about the 820S, but I would venture to guess that they have either different threading distance or gauge, and maybe a different size o-ring seal. The difference would have to very small...

You can't put the wrong one on your vehicle even if you wanted to. The thread size between the FL1A and FL820 are different. They are made by Purolator, similar to the Purolator Premium line. I'd use the one your owners manual calls for.

As this has gotten somewhat confusing, and therefore more interesting (:o] I stepped to the garage and confirmed your points. The thread holes are visibly different between the two filters discussed. You are so right! My V6 1999 Ranger uses the NAPA 21515 and my V8 Mountaineer uses the Supertech ST2. I would be off topic here, except I think these two filters are the same as the two actually under discussion for other vehicles/years.

You're so right on target! I went down to the parts store and looked at both filters(Purolator's) and the threading IS different even though they are the same size. My problem question wasn't worrying about putting on the wrong one as they are idiot proof. My question is does anybody know why Ford engineers decided to make a different on for the same 4.0L V6 SOHC engine???

Made by Purolator I believe
#10 of 16 to confuse us?!?
Oct 21, 2002 (4:50 pm)
maybe it was clearances in the engine compartment, maybe source country issues (some sort of european metric now! initiative or some such), maybe somebody was just pushing to get the volume up on the new filter part number.
or maybe it was time to make an unwarranted manufacturing change to confuse everybody.
all have been valid reasons for running changes in the past
