Sinotruk Howo Truck Engine Spare Parts Intercooler WG9925530137
| Parameter | Description |
|---|---|
| Function | Cools compressed intake air from the turbocharger to increase air density, improve combustion efficiency, boost engine power, and reduce fuel consumption. |
| Cooling Type | Air-to-Air (Air-Cooled) – uses ambient airflow for heat dissipation |
| Core Material | Aluminum (high thermal conductivity, lightweight, corrosion-resistant) |
| End Tanks Material | Typically molded plastic or aluminum alloy |
| Design | Optimized fin and tube structure for maximum heat exchange and minimal pressure drop |
| Mounting Position | Installed between turbocharger outlet and engine intake manifold |
| Weight | Approximately 25 kg |
| Durability | High resistance to vibration, thermal cycling, fatigue, and cracking under high-pessure conditions |
| Thermal Efficiency | High-efficiency heat transfer performance suitable for high-boost turbo systems |
| Pressure Rating | Designed to withstand high boost pressures typical in MC13 and similar heavy-duty diesel engines |

Heavy-Duty Commercial Trucks: Long-haul transport, freight logistics, construction haulage
High-Load Operating Conditions: Suitable for continuous operation under high engine load and elevated temperatures
Turbocharged Diesel Engines: Especially those utilizing high-pressure exhaust gas recirculation (EGR) and advanced combustion strategies
Replacement & Maintenance: Used as a direct replacement during scheduled maintenance or failure due to leaks, blockages, or physical damage
Highway driving
Mountainous terrain requiring sustained power output
Hot climates where efficient intercooling is critical
Proper Installation Required
Ensure all intake connections, clamps, and mounting brackets are securely fastened. Leaks can lead to reduced boost pressure and engine performance issues.
Inspect Associated Components
When replacing the intercooler, inspect:
Intake hoses and couplings
Turbocharger condition
Charge air pressure sensors
EGR system (if applicable)
Avoid Physical Damage
The aluminum fins are sensitive to bending or debris impact. Keep radiator/intercooler area clean and free from road debris.
Clean Cooling Pathway
Regularly clean dust, oil, and dirt buildup on fins to maintain optimal cooling efficiency.
Check for Internal Blockages or Corrosion
Moisture accumulation or poor-quality air filters can cause internal corrosion — inspect periodically.
Use OEM or Equivalent Quality Only
Low-quality replicas may have inferior materials or welding, leading to premature failure under high pressure/temperature.
Leak Testing Recommended
After installation, perform a boost leak test to ensure no air loss in the charge system.
Warranty Information
Varies by supplier:
Typical warranty: 3 to 12 months
Usually excludes damage from improper installation, foreign object damage, or misuse
Environmental Resistance
Designed to resist salt spray, humidity, and wide temperature ranges (-40°C to +120°C operating environment)
