The VT275 Engine is a 4.5 L V-6 engine, with a bi-turbo setup similar to the 6.4-L PowerStroke or MaxxForce 7. You could call the VT275 engine the cross over engine from the VT365 to the MaxxForce 7 Engine because it has the sequential twin-turbocharger system of the 6.4-L PowerStroke or MaxxForce 7 engine and the block design and setup of the VT365. The VT275 Engine was used in the Ford (Low Cab Forward ) LCF 450 & LCF 550, International (Cab Forward) CF500 & the WorkHorse Chassis.
The VT275 engine however was plagued by the same issues that it’s big brother the 6.0-L PowerStroke or Vt365 had. The EGR Coolers commonly fail from it becoming super heated and then it starts to come apart inside the unit. When this happens the VT275 engine starts ingesting coolant from the leaking EGR Cooler. Once this happens the Electronic Control Module detects that the fuel is not the correct ratio and then corrects for it thus injecting more fuel. From there you get an over fueling situation which causes injector problems, head gaskets or catastrophic engine failure. Fortunately our guys at BulletProof Diesel have devised an updated EGR Cooler for these vehicle as well to alleviate these issues. The Straight Through Flow The factory oil cooler needs to be replaced at the same time as the new EGR Cooler is as well.
Once these issues have been taken care then these engine can continue to be a reliable service vehicle in the field. 75% of the core returns from the remanufactured engines that we supply the cores come back attributed to these failures.
