peterbilt 2008 388 feedback

the 388's are the same as a the 379 short hoods, except a longer hood/diff headlights/ and of course diff style eng/rad/acc. but overall still same pete but new engine emissions crap. The dpf is still being used on the new along with the urea, the urea mixes into the dpf to burn off more nox before exiting the stacks, just to clarify. But as far as your truck the cummins is a good engine, keep an eye on your coolant level, because even the new cummins are still having egr cooler internal problems, not as numerous as the pre 2008 but still there, also there are electrical and sensor issues with the dpf itself. make sure you read up all you can on the dpf and make sure it is regenerating itself properly. Also be sure the air filters are being changed with the same filters that came factory with the truck and that the seals for the filter housing is being changed, because there have been issues where other brand filters were used and the seals werent replaced or housings werent secured, and the engines were "dusted" and started to have excessive blowby and cummins would not warranty the overhaul because oe filters were not used. I worked for a peterbilt dealership up until may 2009 so take this info for what it is worth, and good luck.

 

Has absolutely nothing to do with your topic...but your avatar is hilarious!

 

like I said make sure to use the oe air filters when you change them and make sure to use the new seal when they are changed, and you should be ok. most of the canister filters were donnelson from the factory but you can call your local pete dealer and give them the vin and they can tell you what it came with from the factory and the replacement part #. Good luck.

 

Nice looking truck!
