Decoding Ford Part Numbers

Recommended Posts

We've all seen a Ford part number, and wondered about that alphabet soup.

First Position = Year

A = 1940's (rare to see)

B = 1950's

C = 1960's

D = 1970's

E = 1980's

Second Position = Year of the decade.....F8 would be 1998

Third Position = Vehicle Line

C = Mercury Capri (60's - 70's), Escort

D = Maverick, Granada, Taurus, 96 and later Taurus/Sable common parts

E = Escort

F = common Tempo/Escort parts (same parts, different body panels)

G = Mercury Montego, Monarch

H = Ford heavy truck

J = marine (boat engines, stationary power plants)

Z = Mustang or Ford non-vehicle-specific part

2 = Probe

3 = Tempo

4 = 96+ Sable body parts

The Fourth position will identify the Engineering Group the part belongs to

M= Performance/Holman Moody

P = Automatic Transmission

R = Manual Transmission

U = Axle and Driveshaft

X = SVO/SVT, Emissions, Economy

Y = Lincoln/Mercury Service Parts

Z = Ford Service Parts

The Center group is the basic part number for the part. If part of a pair, then the lower number is the right hand side (i.e. 120 is right, and 121 is left). The only exception is power window motors for only one car. Series means the 1000, 1001, .... 1999, 1A001, to 1Z999 where every basic part number is a unique part on a car, and the same part 'name' for a different car is differentiated by the prefix.

1000-1250 = Wheels, hubs and drums

19100 = Fire Extinguishers

19500-19585 = Custom Accessories; Appearance and maintenance materials

The letter after the second dash is the revision code. The A at the end of the number indicates that the part is the first version. If it was revised once, it would be B. If it was revised again, it would be C, and so on. When they run out of letters, it becomes AA, AB, and so on.

Note that if your '96 car has a part number such as F4DZ-2B120A, then you know the part was first used on '94 cars, was installed on '95s and is still being used unchanged on '96s.

Part #'s are not necessarily the same as casting #'s or the numbers on the part. Line numbers are different still.

Date codes are sometimes included on parts. The first digit is the year. To determine the decade, refer to the part number's prefix. The second digit is the month. The third digit is the day of the month.

A= January

B= February

C= March

D= April

E= May

F= June

G= July

H= August


J= September

K= October

L= November

M= December

I have culled this from sources ALL over the internet to make it as complete as possible. I'm sure as I find better information, this will be updated.
