Ford, Toyota, Hyundai? What’s The Difference?

By May 22, 2014October 18th, 2018Parts Counter

If you’ve been employed as a Parts Professional (don’t ya love how lofty that title sounds?) then you obviously have become familiar, if not comfortable, with your OEM part numbering system.

If you are a Ford guy, you know base numbers, major and minor sections. If you are a Toyota or Hyundai parts guy/gal, you know PNCs (Part Name Codes) and illustrated sections. I’ve been around this long enough to know that once a parts guy or gal gets it (understands their numbering system) then they have a certain comfort level in knowing they can do their job and do it well.

The anxiety will mostly be due to the perception that “the other guy’s” part numbering system is totally different, more complex, and will mean that even the most experienced parts pro will be starting over at square one with the new numbering system.

Please say it ain’t so!


There are actually more similarities between OEM part numbering systems than one might think. And finding your way around an unfamiliar OEM parts data set is not mysterious enough to cause any undue perspiration.

Before making the leap from Freddy Ford to Tommy Toyota or Helen Hyundai, it will help you to first understand a few basic things about automotive cataloging. Once you do, you’ll soon be back in your comfort zone, regardless of what OEM part numbering systems you’re looking at.

OK. Let’s look at basic numbers compared to PNCs.

In principle, the two are really quite the same. Other than the small OEM “nuances” (i.e.: unclear things that every OEM puts in their catalog to make your day interesting) a Ford basic number or a Toyota/Hyundai PNC are “exactly” the same thing.

Ford base number 8005 is a radiator. Toyota PNC for a radiator is 16400 and Hyundai/Kia PNC for a radiator is 25310.

Here are a few more base number vs PNC examples:

Ford Toyota Hyundai
16612=hood 53301=hood 66400=hood
6731=oil filter 15601=oil filter 26300=oil filter
8200-rad grille 53111=rad grille 86351=rad grille

The problem is there are a “gazillion” PNCs and base numbers, so even the department “brainiac” can’t remember all of them. And, in case you do not know, cannot remember, or just don’t care what the base or PNC is, we have Section information.

Section, or illustrated section, is a piece of the car that the OEM has drawn up. Parts guys typically refer to sections simply as illustrations. Illustrations contain the individual parts related to the section.

But even Sections have a method to their madness and are organized in a similar fashion regardless of OEM. Again, each OEM has some individual nuances that will make you earn your money, but in the end, their layout is different but the same.

In Toyota, they mostly have seven major sections. They are: 1 = Tool, 2 = Engine, 3 = Fuel and Engine Control, 4 = Drive, 5 = Body, 6 = Electrical and finally 7 = Local Products/Accessories.

Hyundai is very similar, and their major sections are as follows: ENGINE, TRANSMISSION, CHASSIS, BODY, TRIM, ELECTRICAL – with no number designation.

As for Ford, here comes the first nuance. In newer vehicles, those built roughly after 2000-2001, Ford switched to a GCAT (Global Catalog Format) and the GCAT section index matches up fairly close to Toyota & Hyundai.

Ford GCAT sections are as follows: 1 = Information and Customization, 2 = Chassis, 3 = Power Train, 4 = Electrical, 5 = Body and Paint. For older Ford vehicles, those built from about 1999 back to about 1940, Ford’s major sections were 10 for wheels and hubs, 20 for brakes, 30 for steering, 40 for rear end and drive shaft, 50 for frame and exhaust, 60 for engine, 70 for transmission, 80 for cooling, all the way to 800 for interior trim parts.

car-engineIn all the OEMs we’ve mentioned, there are Minor Sections within Major Sections. In Toyota, if we access Major Section 2 – Engine, we will find a Minor Section for Cylinder Head, which is a “minor section” of the “major section” engine. Makes sense to me.
The same holds true for Hyundai and Ford. If we access the Major Section ENGINE in Hyundai, Power Train in Ford GCAT or 60 in Ford older vehicles, we’ll be able to access engine Minor Sections such as Cylinder Head, Timing Chain, Camshaft, etc. Once we are at the appropriate Minor Section, regardless of OEM, we will be able to select the part number.

Lastly, except for a few thousand “nuances”, the actual part number has a “genetic link” back to the MAJOR and MINOR sections. The DNA that links this all together can be seen in a subtle relationship between the base number, PNC and Section number.

For example, a water pump basic number in Ford is 8501 and it will be found in the cooling section 80. The PNC for a water pump in Toyota would be 16100 and would be found in section 16.01. In Hyundai, a water pump PNC is 25100 and it is found in Major Section 25 and Minor Section 251.

So you see, fellow Parts Professionals, they were right all along!
