Hi guys i am a volvo master tech ive been at the same dealer in Northeast,PA for 11 years i know there is other posts for volvo and mack related topics but i decided to start my own and try to clear the air about some things at the most throw a few very good opinions out there i have seen guys on here say volvo engines are junk they are garbage.....not true besides the new 13 liter dpf engines this is not true the actual meat and potatoes of volvo engines are damn near bulletproof now the emissions related items and electronic components are giving the volvo engines a bad name the only engine that you mack guys out there wont see to much of and will love cuz they are so easy to work on is the 16 liter which i believe will be called the mp-10 (its the big horse dpf engine)now the 13 liter is also a great engine however they r droppin like flies mainly due to injector cup failures,turbos,engine wiring harnesses now i have also seen some people say they have totally dropped any mack ideas and basically said screw mack...on the volvo side of things this is not true they r coming out with stainless steel cups which was a mack design,they are also goin to be using mack designed wiring harnesses which seem to hold up alot better,also yes the new mack engines are dressed up volvo engines do not let anyone fool you or tell u otherwise,now as to working on these engines they are very very very easy to work on they are basically idiot proof however this will take awhile until you mack guys get to know them very good and also when diagnosin them throw all of your logic and basic skills out the window there is so many design flaws and alot of engineering flaws when it comes to these engines,now alot of people have said that they are not reliable and are junk....lol this is 100 percent true this merger i feel will build volvos reputation due to the fact of volvo using alot of macks great engineering ideas for there products and its going to kill the amazing reputation that mack has built there bottom line on just because of one big thing and i hate to say it and everyone can call me a liar but its true you are gonna see alot of new design items being put on mack engines before you see them on volvo engines because mack engines are going to be the test whores,i just came back from a new products school and wait til u guys see the newest epa engine hahahahahahahaha J.O.K.E JOKE after this class i found a 87 superliner with a magnum 500 i bought it and am in the process of fixing it up with the little things it needs and will be paintin it next week cuz in a year and a half i am done with this bs and am going to be signing on with a local transfer station and ill be haulin 53 foot garbage trailers makin 300 bucks mor a week and no aggrevation manufactuers are getting out of hand with these federal law regulated designs and its a shame cuz alot of honest truck owners and workers are the ones that are getting hurt well im done ramblin on if anyone has any complaints or questions feel free to shoot them my way and ill try my best to help resolve them but All You Mack Guys And DieHard Mack Enthusiasts The End Of Great Products And Trucks Is Here
