2010 Cummins ISX 470 any good advice.

That Cummins is a good engine for the most part all trucks have break downs the most common complaint I hear about the dd15 is that's its in a freightliner and injector cups can fail before 500000 but both good engines if taken care of

 

Don't buy any truck made in exactly the range you are eyeing. Either be emissions non compliant (no dpf or def) or be compliant with the new stuff (both dpf+ def). A dpf only truck is a great way to truly throw away your retirement dollars. If you go ahead anyway, you will likely wish you had just lit your money on fire instead of the constant headaches you will likely (95%) encounter.

 

Good motor but be prepared to replace egr valve and leaking egr cooler I drive a 2010 isx 550 both had to be replaced other than that good motor with good power.

 

Find what CO. you will be working for,and what type trailer they pull if they wont go to CA. then buy 2003 or older,you can go thru years of retirement cash in a few short bad weeks?

 

Read the cummins cm871 technical thread by Rawze. Awesome read about the egr and dpf systems on the isx of those years. Most of it applies to the egr system in the earlier cm870 isx as well, took some figuring out the differences but he was dead on with what was causing my egr related poor mpg.

 

Thank Rawze! I have that unicorn of ISX's, almost 700k with its original egr cooler still intact. After reading his thread I checked my diff press sensor and maint records from Landair and discovered it was also original. $160 dollars from cummins dealer +20 minutes of install time and I have a Happy ISX!
