TYC 18136 Intercooler

Intercooler Overview

This TYC intercooler is built for direct replacement applications with confirmed fitment for select Buick and Chevrolet models. It uses an aluminum core and crossflow design to support charge-air cooling in a compact package.

Key Features

• Aluminum core construction for efficient heat transfer.
• Crossflow layout for consistent airflow through the core.
• Spring lock inlet and outlet connections for OE-style attachment.
• 51 mm inlet and outlet diameters for matched connection sizing.
• Core dimensions: 25.35 in length, 2.52 in height, and 4.30 in thickness.

Detailed Fitment and Application

Compatible with 2020-2023 Buick Encore GX and 2021-2023 Chevrolet Trailblazer. This TYC 18136 intercooler is a practical replacement for vehicles that use the listed spring-lock, 51 mm connection setup. The aluminum core and crossflow configuration support stable charge-air cooling performance in the factory-style layout.

This part cross-references GM 42805212 and GM3012127 for the same application.

What It Helps Address

• Reduced charge-air cooling efficiency from a damaged core.
• Leaks at the inlet or outlet connection points.
• Heat-related performance loss in the intake charge path.
• Fitment issues when replacing a worn OE-style intercooler.

Installation Notes and Quality

Verify the spring lock connection style and 51 mm inlet and outlet sizing before installation. Confirm the vehicle’s cooling system layout matches the listed fitment for the Buick Encore GX or Chevrolet Trailblazer. TYC manufactures replacement cooling components with application-specific dimensions and connection types for accurate fitment.
