Another question we get is Why Does My Truck Have A DEF System? We will look at both questions and give you some answers of why Diesel Trucks have a DEF System and why the Service DEF System message comes up on the dash. We will look at Why Does My Truck Have A DEF System first. The main reason late model Diesel Trucks and Cars have a DEF System is to control the amount of Nitrogen Oxides (NOx) that the vehicle emits. The EPA has mandated that the OEM’s had to control the Emissions that the Diesel Engine emits. The DEF Fluid gets injected into the exhaust stream before the Selective Catalytic Reduction (SCR) unit. The Def Fluid goes through a mixing tube and enters the SCR unit, and the DEF Fluid reacts with the SCR and reduces the NOx and lowers the emissions coming out of the tailpipe. When the Servi ... read more

It doesn’t matter if the engine runs on gas and it’s in a car or if it runs on Diesel and it’s in a Commercial Vehicle. We’re going to only look at one reason and that is the Camshaft and the Lifters that make the valves move. The Camshaft has to be timed with the Crankshaft if it gets out of time it will cause the engine to run poorly and misfire causing the engine to shake and if its bad enough to shake the whole vehicle. Another thing that can go wrong with a Camshaft is the lobe that the lifter rides on can get worn down and wear the bottom of the lifter when it gets bad enough it will cause a Misfire. What happens is as the Camshaft Lobe and Lifter get worn it can’t open the valve the correct amount if it’s the Intake Lo ... read more
