Here's a list of acronymns (abreviations) I began 10 years ago. That was before the 6.0L, 6.4, and 6.7 engines, so very little of the new stuff is in that list.

These acronyms are only the ones that apply to Ford diesel trucks, and do not include the typical internet acronyms or teeny bopper texting shorthand such ROTFL or CUL8er.

Feel free to add additional acronyms that apply to Ford diesel trucks, but leave the internet and texting shorthand to other links.

10 years ago I began a similar thread. That was under different forums software, so it includes a lot of garbage characters where gremlins, quotes or other formatting were included, but you might get a kick out of it.

Decoding Ford transmission name: The first number is the number of gears. The R means rear-wheel drive. And the last number is one-tenth of the max torque after the torque converter that the tranny is designed to handle. So 4R100 is a 4-speed tranny designed to handle up to 1000 lb/ft torque coming out of the torque converter, or about 500 lb/ft at the flywheel. (The torque converter increases the torque up to about double what the engines produces). The 2011 6R140 is a 6-speed truck tranny designed to handle up to about 700 lb/ft at the flywheel.

Got another one for you that drove me nuts until I figured it out (new diesel guy here)

uvch - under valve cover harness: the wire harness that runs throught the vavle cover gasket and connect to the injectors on 1995 7.3L turbo
Thanks for the post. One thing I noticed is EGT is in there twice. One should be EGR?

Yep. You got me. :)
awsome post, I was having trouble trying to figure out all of these as well.
awsome post, ...
Thanx for the flowers.
Nice job Smokey... haven't seen you around much lately.

God Bless
Thanks so much for the acronym list. Huge help while reading these posts

Trying to find out what HPOP is. I see it all over the place, and my car is having a hard time starting, but I can't find what it is, where it is, and how to test it. Argh, too many acronyms!
High Pressure Oil Pump
Yes, high pressure oil pump (HPOP). Your diesel has two oil pumps, one for ordinary lubrication duties, and the other to create extremely high pressure used to fire the injectors. It's related to HEUI (hydraulic-actuated electronically-controlled unit injector). If the HPOP is not working right, then the injectors won't fire, and if the injectors won't fire, the engine is not going to start or run.

The HPOP is rarely mentioned when discussing stock engines or even mildly-tuned engines with up to around 350 HP. The hot rodders talk about it because you need a more powerful HPOP to produce more than about 350 HP from a 7.3L engine.

Here's one source:
You have to scroll down but then you'll see it's a "HIGH VOLUME HIGH PRESSURE OIL PUMP".
I've seen a new one I can't figure out. IIRC. I don't think it's a part. Help me out.
If I remember correctly, IMHO...

Thanks RT, I wouldn't have guessed that one in a million years and I consider myself pretty good with acronyms.

It's not related to Ford diesel trucks, so it's not in the above list. Note this sentence in the topic starter post: "These acronyms are only the ones that apply to Ford diesel trucks, and do not include the typical internet acronyms or teeny bopper texting shorthand such ROTFL or CUL8er." Or IMHO or IIRC.

IIRC is internet forums or FaceBook or Twitter posting shorthand for "if I recall correctly"
While you're recollecting, I'm remembering. :)

REALLY NOT being a Ball buster here but DOT - API - SAE - FAQ - are not really directly related to Ford trucks either. But I get why you included them and why you included the information about not including the internet teeny bopper lingo. But I have to admit, I have been wanting to know what IIRC meant for some time now and was just to shy to ask. Glad I finally read/found this thread. Now where am I going to go on this site to find out why I cannot add a Signature to my profile? I think I figured out that as a free member I cannot add the smiley faces or animated avatars or graphics... But I would think I should be able to add a Signature. Is it as simple as going to my profile page and writing it and hitting save? Cause it's not working for me. HAY!!!! What's going on here???? Now it's showing up!!!!! LOL... Maybe only on new posts I write? I notice my avatar seems to be retroactive when I changed it..... Anyway, Thanks Smokey for all those acronyms. Helps us Noobs out a lot. DDT

Non paying members of the site should be able to do 99% of what us paying members do. Adding the signature is just as easy as what you are saying and I can see the one at the end of your post, but if there is a problem you may need to send a PM to Administrator and let him know what is going on. An animated avatar should be the same way.

As for the smileys are you using the "Post Reply" or the "Quick Reply"? There are no smileys available in the "Quick Reply" area.

That list of acronyms is the best. It just saved me a ton of time :read:. Thank you VERY much. Trapperbill
