Confirm correct model: Use SINOTRUK EPC system to verify compatibility with your VIN/chassis.
Inspect new unit: Check for cracks, porosity, deformation, or damaged threads on mounting flanges.
Clean mating surfaces: Remove all old gasket material, carbon buildup, and rust from adjacent components.
Prepare hardware: Have new high-temperature exhaust gaskets and M10×1.5 bolts ready.
Apply Anti-Seize Lubricant:
Coat bolt threads with high-temperature anti-seize compound (copper-based paste) to prevent seizing during future maintenance.
Position the Manifold Section:
Align carefully with upstream (front manifold) and downstream (turbo inlet) ports.
Do not force misaligned flanges.
Install New Gaskets:
Place new metal exhaust gaskets on both sides.
Never reuse old gaskets — they lose resilience after thermal cycling.
Insert and Tighten Bolts:
Stage 1: 30% torque
Stage 2: 60% torque
Final: 80–90 N·m (confirm exact value per service manual)
Insert bolts finger-tight first.
Torque in crisscross sequence in multiple stages:
Final Inspection:
Ensure no binding or stress on connected piping.
Visually check clearance from wiring, hoses, and frame rails.
