How does one tell if a variation of a part number would be applicable?

For example, if I we're looking for a C5TZ-8260-V and a "Variation" is listed as C5TZ-8260-A, is that a close enough part number to fit or what exactly are these variations where only the last character is different?

Anything else that can be deciphered there? The Group Number is 8260. What all can be told from the C5TZ portion? First application used in 1965 for the 5? Does the T mean Truck? I'm getting bleary eyed reading the MPC, but learning a lot, too. Just trying to make sense of all the info. Point me to the page if I missed it.

Thanks

Number Dummy would be the expert to explain this, but let me give it a shot. There are usually three parts to a part number - prefix, basic part number, and suffix. In your example, C5TZ is the prefix, 8260 is the basic part number, and A or V is the suffix. The prefix tells you which vehicle line the part was originally released into. The C stands for 1960s. (B is the 1950s, D is the 1970s, etc.) The numeral is the exact year, so C5 = 1965 (and D5 would be 1975). T = truck. Z = Ford Division. The basic part number describes whatever the part is and the suffix tells which change level you have after A, the original specification. I would have looked up your example, but my computer won't let me access my copy of the MPC for some reason. Check the applicability boxes for years and models and read the fine print to see which P/N with suffix applies to your vehicle. Hope this didn't confuse you. If it did, N D will be along to correct me and help you. Good luck!

 

C2OZ-8260-H (replaced C5TZ-8260-A) .. Upper Radiator Hose 1965/67 Econoline 170 / 1962/64 Fairlane 170/200
Suffix, more often than not, determines part application, right or left.

C5TZ-8260-F .. Upper Radiator Hose 1965/72 P350/500 254 diesel.

C5TZ-8260-P .. Upper Radiator Hose 1965/72 B600 300 H/D.

C4TZ-13489-E Right & C4TZ-13489-F Left .. Taillamp Bezels.

1964/66 F100/250 2WD & 1966 F100 4WD Styleside Custom Cab/Ranger / 1966/77 Bronco.

 

OK, that helps alot. Basically they are not interchangeable which is good to know.

I've got the Master Parts CD from HipoParts and trying to look up a fan belt for my 1966 F250 w/300 6 cylinder. I'm looking at the main index for Fan Belt or Belt,Fan but not seeing anything in either area of the index. What category should I be looking for? I've always called it a fan belt, but maybe they call it something else?

EDIT: Looks like they call it a Drive Belt. I think I'm on it now.

 

Text, section 86.1 ~ Page 18 // Part number prefixes with 5 digits = CC as first 2 = Canada only.

(2): with dual belt alternator

 

I only have a single pulley on the alternator and fan so that looks like a

C9PZ-8620-GK

Is that right? How do you figure out what parts this number supercedes?

Single fan belt on this engine. Isn't that a serpentine?

Happy Friday!!

 

Obsolete-Supercede-Interchange Catalog lists the original part number as C3VY-8620-B / There were no sizes listed with original part numbers, no Auto-Lite/Motorcraft part numbers.

It was a PITA to look up belts, and if not in stock was another PITA to figure out what else might work. Walk down aisle with belt stretcher, take belt off hook, measure it, no that won't work, keep walking, measuring.

1969: FoMoCo changed most of the belt part numbers, many have C9PZ prefixes, specs are listed, as are Auto-Lite part numbers, became Motorcraft part numbers in 1973.

So, if JB-430-LA not in stock, JB-436-LA (15/32" wide x 43.6" long) might work as a substitution (see page 2).

 

boy sure glad i don't need any parts
