Vg260011136
Sinotruk HOWO
| Attribute | Description |
|---|---|
| Part Name | Rear Exhaust Manifold / Engine Exhaust Collector |
| OEM Number | VG2600111136 |
| Position | Installed on the rear side of the engine block, connecting to rear cylinder ports |
| Manifold Type | Two-piece modular design — this is the rear half |
| Material | High-strength ductile cast iron (nodular graphite cast iron) |
| Heat Resistance | Withstands continuous temperatures up to 800°C, peak spikes over 950°C |
| Function | |
| • Collects exhaust gases from rear cylinders | |
| • Directs flow to turbocharger or downpipe | |
| • Supports balanced scavenging and backpressure control | |
| Weight | Approx. 15–25 kg (standard OEM weight for large cast piece) |
| Sealing Method | Uses high-temperature exhaust gasket between manifold and cylinder head |
| Connection Points | |
| • Inlet: Bolted to cylinder head (cylinders #4, #5, #6) | |
| • Outlet: Connects to turbocharger turbine housing or exhaust downpipe | |
| Compatibility | Designed for use with turbocharged variants of WD615 engine |
| Condition | Brand new (OEM fresh stock or premium aftermarket) |

Professional Installation Required
Involves working near hot exhaust components and tight engine bays.
Must be performed by trained technicians familiar with diesel engine systems.
Use New Exhaust Gasket
Always install a new high-temperature exhaust manifold gasket.
Reusing old gaskets leads to leaks and rework.
Clean Mounting Surfaces
Cylinder head exhaust ports
Manifold flange
Remove carbon deposits, old gasket material, and corrosion from:
Use wire brush or flat file — do not gouge metal.
Torque Bolts to Specification
Follow crisscross tightening pattern as per service manual.
Typical torque: 60–80 Nm (check exact value for your model).
Under-tightening → leak; Over-tightening → cracked flange.
Allow for Thermal Expansion
Do not overtighten outlet connection to turbo/downpipe.
Use flexible bellows or slip joint where applicable.
Avoid Cold Quenching After Operation
Never spray water or coolant on hot manifold — causes thermal shock and cracking.
Inspect Turbocharger Connection
Ensure proper alignment with turbo inlet flange.
Misalignment adds stress and may damage turbine housing.
Check for Cracks Before Installation
Inspect for hairline cracks, especially around weld zones and bolt holes.
Tap test with soft hammer — hollow sound indicates internal failure.
Preheat During Cold Starts (Cold Climates)
Avoid sudden high-load operation when cold — gradual warm-up reduces thermal stress.
Storage Advice
Store upright in dry indoor environment.
Keep gasket surface covered to prevent oxidation.
