Product Overview

The oil filter housing with integrated cooler, OEM number 55566784, is fitted to the Chevrolet Cruze, Sonic, and Trax, and the Buick Encore, covering the 1.4L turbo engine across the 2011-2021 production run. Since this assembly spans several of GM's highest-volume compact models across both Chevrolet and Buick, it's a high-turnover part number worth stocking in volume for distributors serving GM parts demand.

A worn or leaking oil filter housing typically shows up as visible oil leaks, low engine oil level, or engine overheating from restricted oil cooling. GSK Auto manufactures this assembly to OEM specification at our Ningbo, China facility, with every unit tested before packing. We supply at wholesale volume with low MOQ and support private label packaging, with our team available to confirm fitment before shipping.

What Is an Oil Filter Housing with Cooler?

Function: This combined assembly houses the engine oil filter while also acting as a heat exchanger, transferring heat between engine oil and coolant to keep oil temperature within its designed operating range.

Working Principle: Engine oil passes through the housing and filter element before circulating through the integrated cooler section, where heat is transferred to the engine's coolant, helping regulate oil temperature and viscosity.

Importance: On a turbocharged 4-cylinder platform, a properly functioning oil cooler and filter housing is essential for maintaining oil temperature control and overall engine efficiency and longevity.

Common Failures & Signs: Visible oil leaks near the housing or filter cap. Low engine oil level from a slow leak. Excessive corrosion at the housing seals. Engine running hotter than normal due to reduced oil cooling capacity.
