| Manufacturer | ACDelco |
|---|---|
| Manufacturer Part Number | 55581537 |
| Included Components | Engine Oil Filter Housing |
| Product Grade | Replacement Part |
This ACDelco engine oil filter housing assembly replaces the factory housing, cap, and O-ring to restore the oil filtration cover on supported engines. It is typically used when the original housing is cracked, leaking, or during engine maintenance that requires a new housing to secure the spin-on or cartridge-style filter.

In practice the unit simplifies reinstalling the filter cap and seal, reduces the risk of leaks compared with worn housings, and keeps oil flow and pressure consistent when installed correctly. Limitations are that fitment is listed as universal rather than vehicle-specific, so verify compatibility with the GMC Terrain model year and engine before purchase, and installers may need to transfer or replace any model-specific sensors or fasteners during installation.
Best for: Balanced buyers who want a factory-quality replacement housing that restores reliability after a leak or failure and prefer parts from a recognized brand for routine maintenance and repairs.
Less Ideal for: Buyers who need a guaranteed vehicle-specific direct-fit part without additional verification or those who prefer an original factory part number listed explicitly for their exact Terrain model year.
- Complete housing assembly includes cap and O-ring for one-stop replacement
- Made by ACDelco and positioned as a professional aftermarket part
- Manufactured to meet expected fit, form, and function for engine systems
- Backed by a 24 month limited parts warranty

Verdict: A complete, ready-to-install aftermarket oil filter and metal cap kit that restores factory-style fit and durability for compatible GMC Terrain engines.
Choosing the Right GMC Terrain Oil Filter Housing: Key Factors to Consider
Material and Construction
The material used for an oil filter housing affects durability and heat tolerance. Housings made from robust metals or high-grade engineered polymers resist warping and cracking under repeated thermal cycles, which reduces the risk of sudden failures.
Construction quality also determines long-term performance. Look for consistent machining or molding with clean sealing surfaces and reinforcement where stress concentrates. These attributes influence both leak prevention and the housing's ability to maintain correct alignment with the engine and filter element.
Sealing Design and Gasket Compatibility
A good sealing design minimizes the likelihood of oil filter housing leak and simplifies installation. The housing should interface cleanly with a reliable gasket or seal that maintains compression over time without extruding or tearing.
Compatibility with OEM-style gaskets or high-quality aftermarket seals is important because replacement seals wear. Consider whether the housing uses replaceable seals and whether those seals are standard part numbers for easier sourcing and service.
Fitment and Mounting Accuracy
Precise fitment ensures the housing aligns correctly with engine ports and mounting studs. Poorly fitting housings can stress mounting hardware and create gaps that lead to leaks or uneven pressure distribution.
Confirm that the housing matches the GMC Terrain-specific mounting geometry and fluid passages. Accurate dimensions reduce installation time and the chance of requiring additional adjustments or sealants.
Resistance to Cracking and Fatigue
Cracking is a common failure mode for oil filter housings exposed to heat cycles and vibration. Materials and design features that distribute stress and avoid sharp corners or thin sections are less prone to fatigue-related cracking.
Inspect design details such as ribbing, uniform wall thickness, and reinforced bolt bosses. These characteristics help the housing withstand repeated thermal expansion and contraction without developing stress fractures.
Serviceability and Access
Ease of access affects how simple routine oil changes and inspections will be. A housing that is straightforward to remove and reinstall reduces the time and complexity of service, and lowers the risk of installation errors that can cause leaks.
Consider whether the housing allows filter changes without extensive disassembly, and whether it uses common fasteners and torques that can be achieved with basic hand tools. Clear access to sealing surfaces also makes it easier to inspect and replace gaskets or seals.
Compatibility with Replacement Parts
Availability of compatible gaskets, seals, and filter elements matters for long-term maintenance. Housings that accept widely available replacement seals and use standard filter interfaces simplify future servicing and reduce downtime.
Confirm part numbers or seal dimensions where possible. Readily sourced replacement components mean you can address oil filter housing symptoms quickly if issues arise, without having to replace the entire housing.
How We Chose the Best GMC Terrain Oil Filter Housing
We focused on components that directly affect oil containment and pressure stability. Primary evaluation criteria included housing material and construction quality, sealing design and compatibility with replacement gaskets or seals, fitment accuracy to the GMC Terrain mounting points, and ease of installation including accessibility and required tools. We also considered resistance to common failure modes such as cracking from heat cycling and fatigue, and how readily the housing accepts standard oil filters and service procedures. Excluded from consideration were items that required vehicle modification, adapters, or unsupported aftermarket alterations. We did not include housings with unclear fitment information or that lacked verifiable material specifications. The final shortlist emphasizes units that balance long-term durability, reliable sealing against leaks, and straightforward serviceability for routine oil changes.
Our full evaluation process is outlined in our review methodology.
FAQ
What are common oil filter housing symptoms on a GMC Terrain?
Common symptoms include visible oil leaks around the housing, a drop or fluctuation in oil pressure, and oil residue on nearby engine components. You may also notice an increase in oil consumption or warning lights related to oil pressure in some cases. These signs often appear gradually as seals age or if the housing develops hairline cracks.
Can I replace the oil filter housing myself?
Many owners can replace the housing with moderate mechanical skill and basic hand tools. The job typically involves draining or containing residual oil, removing mounting fasteners, swapping the housing and seal, and torquing bolts to specification. Take care to clean sealing surfaces and follow proper torque sequences to avoid leaks.
How important is using the correct gasket or seal?
Using the correct gasket or seal is critical because it ensures a reliable oil-tight joint and helps maintain proper oil pressure. An incorrect or damaged seal can lead to leaks and potential engine damage. Choose seals that match the housing design and material to maintain compression and heat resistance.
What causes oil filter housing cracking?
Cracking often results from repeated thermal cycling, mechanical stress from over-tightening fasteners, or impact damage. Materials that are too thin or designs with stress concentration points are more likely to crack over time. Regular inspections can help detect early signs before a small crack leads to significant leakage.
How can I check for a leak without removing the housing?
Visually inspect the area around the housing for fresh oil, wetness, or darkened residue after running the engine briefly. Wipe the area clean, run the engine, and then recheck to confirm active leakage. A pressure or dye test performed by a technician can also help pinpoint the source if visual inspection is inconclusive.
When should the housing be replaced instead of the gasket?
Replace the entire housing when there are visible cracks, significant warping, damaged mating surfaces, or when the mounting points are compromised. If the housing is structurally sound and only the seal is failing, replacing the gasket or seal is usually sufficient. The decision depends on the extent of damage and long-term reliability considerations.
Conclusion
When choosing a GMC Terrain oil filter housing, prioritize sealing reliability, correct fitment, and material durability. These aspects have the biggest impact on preventing leaks, maintaining oil pressure, and ensuring consistent engine lubrication. Balance ease of service and compatibility with replacement seals against resistance to cracking and fatigue. Focusing on these criteria will help you select a housing that reduces maintenance headaches and supports long-term engine health.
