Product Description

International VT365 Engine

The VT365 engine replaced the ever popular workhorse, the T444E in the 2003 International applications. The VT365 was produced up until the 2010 model years. The VT365 engine was also released in a similar version to Ford known as the 6.0L PowerStroke. The Ford 6.0 PowerStroke was used for the Ford F-Series Pickups for the 2003-2007 model years. The Ford E-Series vansåÊused the engine until 2010 model year. The VT365 Engine usedåÊan ECM (Engine Control Module) and a FICM (Fuel Injection Control Module) to control the engine and injectors. This was different from the previous generation engines that usedåÊan IDM (Injector Drive Module) and a ECM. The VT365 still used the HEUI injectors like previous generations PowerStrrokes, but G-2 version. The 6.0 PowerStrokeåÊengine produced up to 325HP with the additional of VGT (Variable-Geometry Turbo). The VGT turbo increased throttle response for these vehicles.The HPåÊin the International versions engines were dialed back for longevity. The VT365 Engine was used in many different applications and were highly customized for each one.

Just like the 6.0 PowerStroke, the EGR Cooler was one of the problematic components that need to be replaced frequently. If not it caused catastrophic engine failure. Bulletproof Diesel in Arizona came up withåÊa Stainless Steel Straight Flow Through design to replace the faulty one. ARP released special head studs instead of head bolts to alleviate the issues with the cylinder heads blowing head gaskets.

The VT365 engine did not suffer as many engine failures like theåÊ6.0L PowerStroke did. However the EGR Coolers did still fail but not as much. Possibly because of the lower horsepower ratings. Bulletproof Diesel still provided the EGR Coolers to In the Ford Applications every pony was carefully packed into the engine.
