Paccar MX Engine ???

I've owned one for the last 18 months,,, i have no idea how to answer your question without using profanities, daf pacar, and the entire dealership network should be absolutely ashamed of themselves, if they were samarie they would be made to fall on their swords after begging for forgivness, hmm no profanities

 

Oh, i know that one,,, your egr is defective and soon will crash the motor, it spewing coolent into your exhaust

 

I think the only way to show pacar what you really think about there company would be a good prison raping of their ceo and board members, then make them drink a gallon of def, oh wait, you can't, its always frozen!

 

I am so glad where my trucks work there is no need for all this bolt on crap. Till next year when we start paying carbon penalties for "older technology". These DAF engines without all that bolt on 5h!t are pretty good. Just their oil coolers are troublesome if drivers pick revs up before oil temp raises.

 

I have a 455 paccar motor in a t700 it keeps losing power won't hardly pull itself down hill and exhaust gas temperature comes on as a fault in the engine anybody know what that could be

 

I just purchase a 2013 T700 with 521,000 miles and the truck fuel mileage is horrible.Dont know if it’s the Paccar engine or the truck just a bad investment.

 

I have a 2013 Pete 386 Heavy Spec 18spd with the 455hp mx13....

Terrible at fuel man, not heavy around 5 to 5.5mpg, 45,000lbs about 4.8mpg.......

I am looking into doing a top end set and a engine tune.

 

I just got it out the KW dealer last week,Gonna see if the fuel mileage have increase once I get a new driver for it.

 

Please keep me updated. What did KW do for it? Top end set
