I was wondering if anyone knows if there is any differents 7.3 form 2000 to 2003. I just picked up a F450 with a blown motor & I know where I can pick up a 03 7.3 for a great price. I just want to make sure the 03 will work in the 00.

Thanks for any help

 

Moved to the 1999 - 2003 7.3L Powerstroke Diesel forum.

 

Simple answer is it is a direct replacement, so yes it will work. One difference will be the powdered metal rods in the 2003 vs likely forged rods in the 2000. Only an issue if you are going for serious horsepower.

 

Yep, everything should be identical unless there was an extra wire for an accessory or something.

 

Indeed, plus the Glow Plugs on the 2000 are operated by a relay. on a 2003 they have a GPCM (Glow Plug Control Module) I dont know if the ECM needs to be flashed or changed to operate the Glowplugs.

 

I when I did the my swap. I just kept all my wiring harness stuff and put it on the new engine and used my electronics.

 

On all 2003's? Even non-California trucks?

Huh, I didn't know that. I know the 6.0's were like that, but I didn't know Ford did that to the 2003 7.3's too.

My 2003 GP's are Relay operated.

 

mine too... Only California 7.3's have the GPCM and I believe all the Ex's did as well, Cali or not

 

Hey Thanks for all the great info. So it looks like pretty easy straight swap. I believe its a cali truck since I live Sacramento Ca

 

Thanks. I was kinda surprised when I saw the other post stating all 2003 7.3's were GPCM'd.

Even though I was 100% sure that wasn't the case, when I read that, it became 99.99% SURE, lol!

I live in Ca, but do not have a cali truck.

 

Ditto again!

 

Ops my mistake, I thought all 02 and 03 7.3's had the GPCM.

 

Ah, ok.

All 6.0's are GPCM'd, but when it comes to the F250/350 7.3's, only the California prepped trucks have the GPCM. As well, all 7.3L Excursion have GPCM's too, whether Cali prepped or not.
