dd15

I recently just got my cdl and purchased a 2015 Freightliner DD15 . Truck has been running smooth for the past couple months . I have been having some def issues though . How many filters does a DEF system have ? What is the difference between a DPF filter and regular def filter ? I notice the...

My 2018 cascadia dd15 engine makes small whistle zzz noise when accelerating or let off gas pedal, any guess? Video attached thanks

Has anybody run into an issue with a 2009 DD15 being too long to fit into a 2010 Cascadia Day Cab that had a DD13? Had a customer bring in a 2009 Cascadia Sleeper that hit a horse and a 2010 Day Cab with oil starved motor. Removed both engines and when seated in the rear mounts the DD15 sits too...

I am looking all over the internet for accurate pictures/videos of the fuel/water separator for the new cascadia. The big Davco comes up constantly, but not seeing a visual on the Detroit option. This is one of the final specs I need to decide on before making up my mind whether to buy this...

If you’re running 80,000 lbs gross (or less), both the Detroit DD13 and Detroit DD15 can do the job. The real question is which engine is the best overall once you factor in: Fuel economy Emissions system repairs Long-term durability Payload and weight Real-world drivability at common gearing...

Hello and Greetings to all the truckers who make our daily lives much better from helping to bring that fresh food to our tables to those needed building materials to keep building this great country. I will try to be brief but my story is so long, complicated and sadly said, expensive and...

i was watching a video on a 700K inspection of a dd15 2010 at the Detroit factory. I noticed it had 2 cams that sit in a tray over the block but under the head. at least it looked like that. Why does it have 2 cams???

What do you guys think of the Cascadias with a DD15 in it and DEF. I have been reading a lot of negative comments about them. Any of you with experience have a say in this? Because we are debating on getting a International Prostar with a Cummins engine or this Cascadia.
