cummins question??

[thomasinnv]

i know this isn't a cummins forum, but i just have a simple question i know you guys can handle. my buddy has a 2001 cummins, and has been complaining of higher than normal egt's. he is having to tow slower than normal up the same grades becuase the egt's creep up higher than before. boost levels seem to be fine. i was thinking maybe a plugged cat or muffler. what do you guys think? i told him he should at least remove the cat, if not the muffler too. any reason he shouldn't do this? i figure it should help lower his egt's. i am not a cummins guy so i don't know if there is any reason not to do this. will it throw the cel if the cat is removed? any o2 sensor to worry about?

thanks guys!

Also meant to ask what his EGT's are too?

The truck isnt equipped with a cat from the factory.

Have him check the Intake Air Temperature (IAT) sensor...there's only one on the 2nd Gen Cummins and it's located on the driver's side of the block, towards the firewall. If it's fouled up with carbon, just clean it with carb cleaner, dry and reinstall. If these things aren't maintained as part of a Preventive Maintenance program, the truck won't run right. I'm not saying that it's the culprit, but it's one thing to rule out. IIRC, you need a 13/16 socket to get it off. Tell your buddy to go to this site Turbo Diesel Register It will be the best investment he's ever made with that truck.

Good luck.
