The Genuine SINOTRUK HOWO Diesel Engine Turbocharger (VG1034110341) is the high-performance component responsible for forcing compressed air into the combustion chamber, dramatically increasing the engine’s output and torque. As a critical piece of sinotruk spare parts, this turbocharger is specifically designed to match the thermodynamic and airflow requirements of the WD615 and WP10 series engines found in HOWO and SITRAK trucks, ensuring they deliver their full rated horsepower, often in the 371hp to 420hp range.

Installation Notes
Turbocharger replacement is a complex procedure that requires meticulous attention to detail, particularly regarding lubrication and cleanliness. This work must be performed by a qualified technician.
1.Identify Root Cause: Crucially, determine why the old turbo failed (e.g., oil starvation, foreign object damage). Failure to address the root cause will lead to immediate failure of the new VG1034110341.
2.Oil Line Replacement: Always replace the oil feed and drain lines. Clogged lines are the number one cause of turbo bearing failure. Do not use liquid sealant on oil flanges, as it can break off and clog the new turbo’s oil passages.
3.Pre-Lubrication (Priming): This is the most critical step. Before connecting the oil feed line, pour clean engine oil into the turbo’s oil inlet and manually spin the compressor wheel several times. This ensures the high-speed bearings are lubricated before the engine starts. Starting a turbo “dry” will cause failure within seconds.
4.Mounting: Use new, high-quality gaskets and torque the mounting bolts to the manufacturer’s exact specifications. Ensure the oil drain line has a clear, unobstructed path back to the oil pan.
5.Post-Installation Start-up: Disable the fuel system and crank the engine for 10-15 seconds to build oil pressure. Then, start the engine and let it idle for 3-5 minutes before increasing the RPM. This allows the oil to fully circulate and the turbo to reach operating temperature gradually.
Critical Installation Notes
•Cleanliness: The turbocharger is highly sensitive to debris. Ensure the air intake and exhaust manifolds are completely free of foreign objects.
•Engine Shut-down: Advise the driver to always let the engine idle for 2-3 minutes after a long, hard run before shutting it off. This allows the turbo to cool down and prevents oil “coking” in the bearing housing.
