EGR VALVES
The following is my feeble attempt to capture what I just learned - how to find the part number for an EGR valve. But, the info I'm going to include on this page won't get you a part number as that would take page after page after page of listings. So, basically this is just for me to write down how to do it. Sorry! However, if you need to find your truck's EGR valve part number then contact me and I'll see what I can do.
The EGR valve is what meters a small amount of gas from the exhaust system into the intake. But, these valves operate in a very harsh environment and often fail. For many owners that's not a problem as they remove the EGR valve or block it off. However, some want everything on their truck to work properly, and others have to have the EGR system working properly in order to pass emissions tests. So, if yours fails how do you get a replacement?
Many parts stores have replacements, but in most cases these are generic replacements and aren't the specific unit that was intended for the application. They will work but will the vehicle drive correctly and will it pass the emissions tests with a generic valve? Who knows? How, then, can you get the exact item? To do that you need the Ford part number for the EGR valve, and there are two ways to get that:

To do that you need the Ford part number for the EGR valve, and there are two ways to get that:
- CALIBRATION CODE: Ford assigned what is known as a calibration code to each iteration of a number of parameters, like EGR valve, carburetor jetting, ignition advance, etc. If you have the calibration code from the label on the valve cover of your engine then the EGR valve part # can be found for certain. See below for an example of the label and where the code is. And, note that the labels changed in mid-year for 1982 vehicles.
- MODEL APPLICATION TO PARTS LIST CROSS REFERENCE CHART: Go to this chart in Section 93A (Page 1343 is where the F-series trucks start) of Ford's 1980 - 1989 Master Parts Catalog and find your truck by year, model, engine, transmission, and whether CA, High-Altitude, or 50-state emissions. Next to that application will be two columns:
- Calibration Code: Check that you've found the right application by comparing your calibration code to that in the chart. If not, keep looking. But, if you can't find your code on the engine, just assume you've found the right application and go on to the next step
- Parts List Number: This column shows the parts list number for your application. And, since there are over 600 parts lists numbers, each with a different calibration code, you could spend hours looking for the right calibration code. Instead, go to the parts list entry for this application.
- PARTS LIST: In the parts list for the truck in question you'll see an entry for the EGR valve with a part number of something like E2TZ 9D448-K. Unfortunately, those part #'s appear to have been replaced, but the catalog doesn't have the new #. However, if you look to the next column you'll find the "description", which is usually the # that is put on the part. And in the case of the E2TZ 9D448-K valve you'll see E2TE-9D448-K1A & K2A. Those are probably the #'s on the parts, and sometimes you can find that number in a search on the internet.
- IDENTIFICATION CHART: Fortunately Ford provided a way to cross-reference the # on the EGR valve with the part number, and that table starts on Section 94 Page 24 (Page 1813) of the catalog. And, that table appears to have been updated because E2TE-9D448-K1A & E2TE-9D448-K2A both refer to E6PZ 9D448-N, which is obviously a later EGR valve than an E2. Further, that number can be found with a search of the internet.
