Always verify fitment before purchasing.

Manufacture part number: 84454110, GM3012116, Subject material: Aluminum, Length: 27.4 Inch, Thickness: 3.2 Inch, Height: 4.7 Inch, Inlet: 2.4 Inch, Outlet: 2.4 Inch

Why Does the 1.5T Engine Need an Intercooler?

Turbochargers compress intake air before it enters the engine.

This compression generates heat.

Hot intake air can lead to:

• Reduced engine efficiency
• Lower air density
• Reduced turbo performance
• Increased thermal stress

The intercooler lowers intake temperatures and helps maintain consistent performance.

Direct-Fit Replacement Design

The SecosAutoparts intercooler is engineered as a direct replacement for the factory unit.

Benefits include:

• OEM-style installation
• Factory mounting locations
• Direct hose compatibility
• No fabrication required

This makes it ideal for owners looking to restore factory functionality.

All-Aluminum Construction

Material

• Aluminum

Benefits include:

• Excellent heat transfer
• Corrosion resistance
• Lightweight design
• Long-term durability

Aluminum intercoolers are commonly preferred due to their combination of strength and cooling efficiency.

Intercooler Specifications

Dimensions

• Length: 27.4 inches
• Height: 4.7 inches
• Thickness: 3.2 inches

Air Connections

• Inlet Diameter: 2.4 inches
• Outlet Diameter: 2.4 inches

These specifications closely match factory requirements for proper fitment and airflow.

Restores Factory Cooling Efficiency

A worn or damaged intercooler can negatively affect:

• Boost pressure
• Fuel economy
• Acceleration
• Turbocharger efficiency

Replacing the intercooler helps restore proper cooling performance and drivability.

Common Signs of a Failing Intercooler

You may need replacement if you notice:

Reduced Power

The vehicle feels sluggish under acceleration.

Boost Leaks

Pressure loss reduces turbocharger efficiency.

Damaged Cooling Fins

Road debris can reduce airflow and cooling effectiveness.

Oil Residue

Oil around intercooler joints may indicate leaks.

Check Engine Lights

Turbocharger-related fault codes may appear.

Perfect for Daily Drivers

Most Equinox and Terrain owners prioritize:

• Reliability
• Fuel efficiency
• Comfortable commuting
• Long-term ownership

A properly functioning intercooler supports all of these goals.
