Restore Peak Air Density: 4956045 QSK38 Aftercooler Gasket Kit

Product Specifications

Guaranteeing Boost Pressure in the QSK38

The QSK38 relies on dense, cooled intake air to generate its massive horsepower and maintain fuel efficiency. A leak in the aftercooler (charge air cooler) circuit bleeds off valuable turbo boost, leading to higher exhaust gas temperatures and reduced power. The 4956045 aftercooler gasket kit is engineered from high-temperature elastomers designed to withstand the intense thermal cycles of compressed intake air, guaranteeing an airtight seal.

Critical Air Management Components

The 4956045 kit includes exactly what is needed to service the aftercooler assembly securely:

• High-Temp Core Seals: Prevents boost leakage between the cooler core and the intake manifold housing.

• Coolant Transfer O-Rings: Premium Viton rings to seal the coolant circuits running through the heat exchanger.

• Housing Gaskets: Reinforced to accommodate vibrations without tearing or losing compression.

Best Practices for Aftercooler Maintenance

• Surface Cleaning: Ensure the housing flanges are completely free of old gasket material and oxidation.

• Core Inspection: While the aftercooler is apart, inspect the fins for blockages or internal fouling that could restrict airflow.

• Uniform Tightening: Tighten housing bolts evenly to avoid cracking the aluminum components or pinching the new O-rings.
