MaxxForce DT Diesel Engine No Run Problem

I posted a similar video like this one a while back with the same scenario. I thought it was important to show again the importance of what to check when a diesel fails to run.

2013 MaxxForce 7 Diesel Engine Code 3055 Will Not Run

I personally have never experienced a reliable V-8 diesel engine. Maybe it’s the designing around a V-8 engine block that makes it weak in some areas. One failure that was… Continue reading 2013 MaxxForce 7 Diesel Engine Code 3055 Will Not Run

Mercedes Diesel Engine Emissions Shop Talk

There is a substantial difference with emissions between 2007 diesel engines and pre 2007 diesel engines. Several add on components were designed to support the reduction of emissions. The older Mercedes in the video is your basic engine with turbocharger, charge air system and standard exhaust. 2007 required more emission reduction adding a diesel particulate… Continue reading Mercedes Diesel Engine Emissions Shop Talk
