06cgmGTO: Great motor only small problems with these dd motors. Work at Ryder in a us with almost nothing but new detroits nowadays. Honestly really impressed with there reliability considering all the emissions crap on me.
wade w: Egr problems majorly !! DEF problems non stop !! fuel rails have been recalled twice now !! the rear head gasket starts leaking after 160 000 km !! If your from canada and run winters you will have nothing but problems with the dpf filters and system !! I'm changing these out at 250 000 km on some trucks!! If any advice pay the money and get dpf delete on the truck ! at least here in canada its legal !! not to mention the ECM problems !!
wade w: I'm a journyman mechanic that works on the dd15 engine every day ! they are not even compared to a cat engine or cummins !! cat is paired with volvo now so its a cat engine but with a different name ! The dd15's are peices of crap !!! but it keeps me employed !!!
2fast65: Cat dose not build engins fore trucks but are not gone the detroit hase ben a good engine i drive a county plow truck in Mn and i have the option between a detroit or a cummins and i am still un decided. I am looking foreword to having the badest plow truck in Mn Only the best survive!!!!!
Rashad Thomas: Oh yea that engine leaks oil in hard to find places cause its too much stuff attached too the engine. That belt tensioner makes your engine the loudest engine in the parking lot. But the engine gets great mpg and as of right now that's all that matters.
Rashad Thomas: I put 800,000 on a DD15 had many problems. Belt tensioner sucked made belts sound loud then belt came off and truck ran hot.
2 days in shop. Injectors lost power in shop 3 days. Turbo went out another 3 days in shop. EGR cooler went out 1 day in shop. I had too fix a lot of other stuff as well mostly minor. The truck was a Century 2010 got it in 2009. Fuel mpg was great. Even though I had problems with the engine its still better then a
60 series engine. Design a new EGR cooler and belt ten
gwokerism: its not made to inframe only r and r ,, good buy to the old school mobile mechanic....buy we can change external parts....i love the 60 and 50s hopefully they are still around when i quit...i mean i still see 2 cylces out there...
Bladerunner140: Work at a Freightliner dealership and over twenty years in. I should say I liked the 60 Series - best motor made in my opinion but the DD13 and DD15 are junk. I beleive now Cummins ISX series beats this motor soundly. A shame for Detroit.
Bladerunner140: Junk-work on these all the time. High pressure pump issues, turbo pukes and takes out the seconsary turbine then DPF. A shame Detroit merged with Mercedes design. Nothing amazing about this junk motor.
iluvincitingviolence: @halosux4life That wasn't announced an entire year ago when the comment was posted, fool...
halosux4life: @PollockTom do your homework tard....
CAT IS COMING OUT WITH A TRUCK
CrackinVTEC666: @PollockTom FALSE cummins isx crapS on DD look at the 12.7 they dont last worth a damn and now theyve made a 16L DD to compete with the ISX HP/TQ numbers
blackandgold51: I wonder if these engines have the same loud torque as the old DD egnines.
levisnteeshirt: i had a 12.7 that busted 3 pistons and they couldn't find out why ,,, i would avoid a 12.7 at all cost ,,,, i hear there is a bad batch of pistons that were made ,,, they should make a replacement piston for the 12.7 thats all cast iron like the 14.0
William McMillan: Series 60 still paying big bigger dividends on the used truck re sale
William McMillan: This person knows what the engine is all about
William McMillan: yes it does,fact is all New compliant engines have some sort of trap or re generation system
Bernard Roberson: Is Cat on their way out? I hope so that would be very good for Detroit and these great engines. Yes it's a DD 13 and DD16 on their way.
truckinjeff: R.I.P. Series 60! Now make way for bigger and better things!
William McMillan: What really helps this engine be the very best is the 24 valve and drive by wire approach,make no mistake just like cars that were slow to evolve into todays high tech very efficiant fast machines high truck costs demand truck manufactures get smart and develop efficiant reliable and affordable profit machines to move freight. We hope!
