An oil leak in the valley of a Pentastar V6 can point to a warped or cracked oil filter housing, and replacing it with another plastic assembly may leave you worried about the same failure returning. The Dorman 926-959 Oil Filter Housing and Cooler Assembly uses a high-pressure die-cast aluminum housing and arrives as a repair kit with the cooler, filter, cap, seals, gaskets, and mounting bolts. It is a strong option for supported 3.2L and 3.6L Pentastar engines, but exact vehicle fit, correct O-ring selection, sensor transfer, and careful torque procedures matter. This review explains what you receive, how the design differs from the factory-style housing, and who should handle the installation.
Quick Verdict
Rating: 8.7/10, recommended with fitment and installation caveats
Best For: Owners and repair shops replacing a leaking plastic oil filter housing on a verified 3.2L or 3.6L Pentastar application
Bottom Line: The all-aluminum housing and complete repair package address several weak points in the original-style assembly. The tradeoff is a detailed installation under the intake manifold, and the kit does not include the oil pressure or oil temperature sensors.

Key Takeaways
- The 926-959 replaces a failure-prone plastic housing design with a fully cast aluminum housing.
- The package includes the oil cooler, filter, cap, seals, gaskets, and mounting bolts for a complete housing repair.
- Fitment is limited to specific vehicles with supported 3.2L or 3.6L Pentastar engines.
- Owners of 2011-2013 applications must use the later 2014-and-newer oil filter style after the conversion.
- Correct sealing, bolt sequence, torque, and sensor installation are essential to avoid new leaks or fault codes.
Why the Dorman 926-959 Stands Out
The main reason to choose the Dorman 926-959 is its patented OE FIX design. Dorman replaces the plastic housing with aluminum, removes several plastic-welded areas that can warp or leak, and machines the sensor threads directly into the housing instead of relying on brass inserts.
Dorman also uses Parker seals and gaskets and supplies the hardware needed for the housing installation. The oil cooler is part of the package, so you do not have to reuse an old cooler that may already have years of heat cycles and contamination exposure.
The orange filter cap serves a practical purpose on early Pentastar applications. It calls attention to the updated filter requirement, which helps reduce the chance that someone installs the older 2011-2013 cartridge during a future oil change.
What Is the Dorman 926-959?
The Dorman 926-959 is a replacement engine oil filter housing and cooler assembly for select Pentastar V6 engines. The housing sits in the engine valley beneath the intake manifold and holds the cartridge-style oil filter, oil cooler, seals, and related sensor ports.
It is designed for a repair where the original housing has cracked, warped, or started leaking around the housing, cooler, cap, or seals. It can also make sense during other major upper-engine work if the existing plastic housing shows damage, but replacing a leak-free part as preventive maintenance is a decision to make with your technician.
Who Should Buy It?
Best For
- Your verified Pentastar application has an oil leak from the housing or cooler area.
- You want an all-aluminum replacement instead of another factory-style plastic housing.
- You prefer a complete branded kit with seals, hardware, cooler, filter, cap, and warranty support.
Skip If
- Dorman’s fitment tool does not confirm your exact vehicle and engine.
- You need a kit that includes new oil pressure and oil temperature sensors.
- You are not prepared to remove the intake manifold or pay a qualified technician for installation.
What Problems Can the Original Housing Develop?
The factory-style Pentastar oil filter housing is exposed to repeated heat cycles, oil, coolant, and the force applied during filter-cap service. Over time, the plastic can warp or crack, and sealing surfaces can lose their ability to contain oil or coolant.
- Oil in the engine valley: A housing, cooler, cap, sensor, or seal leak can allow oil to collect beneath the intake manifold before it becomes visible lower on the engine.
- Cracks near the filter cap: Excessive cap torque can damage the plastic housing or shift the cap seal.
- Seal leakage: Flattened, damaged, dry, or incorrectly installed O-rings can leak even when the main housing is intact.
- Misdiagnosis: Oil can travel across the engine and make another gasket or component look responsible, so the source should be confirmed before parts are ordered.
The Dorman assembly addresses the housing material and several design weak points, but it cannot correct an inaccurate diagnosis, damaged mating surface, faulty sensor, or installation error.
Materials and Build Quality
Fully Cast Aluminum Housing
The aluminum body is the core upgrade. It is more resistant to the warping and cracking associated with the original plastic design, and Dorman states that its heat-dissipation testing matched original-equipment performance.
Premium Sealing Components
The kit includes 19 seals and gaskets, including parts needed for the housing and intake-manifold work. Dorman identifies the main seals as Parker components designed to meet original-equipment-level material and performance standards.
Machined Sensor Threads and Redesigned Oil Path
The housing uses precision-machined threads instead of brass thread inserts. Dorman also redesigned the oil channel to remove an ultrasonic-welded plastic cover, another area that can distort and leak on a plastic assembly.
Complete Cooler and Filter Package
You receive a new oil cooler, cartridge filter, and cap with the housing. This is more complete than a bare housing, but you still need compatible sensors or must transfer serviceable sensors from the old assembly according to the installation instructions.
Installation and Setup
This repair is more involved than a normal oil-filter change. The housing is below the intake manifold, so you must remove upper-engine components, keep debris out of open ports, clean the mating surfaces, install the correct seals, and tighten fasteners in sequence.
- Confirm the leak and fitment: Check the housing valley, cap, sensors, cooler, and nearby gaskets. Verify the Dorman part against your full vehicle details.
- Work on a cool engine: Disconnect the battery as directed for your vehicle, relieve any relevant pressure, and drain fluids as required by the service procedure.
- Protect open passages: Cover intake ports and oil passages while the assembly is removed. Do not allow dirt, gasket fragments, or tools to enter the engine.
- Select the correct oil-return O-ring: Dorman supplies two front O-rings. Its current guidance calls for the 22.3 mm black O-ring on 2011-2021 applications and the 23 mm blue O-ring on 2022-and-newer applications.
- Lubricate and seat every seal: Use clean engine oil where the instructions specify. A twisted, pinched, dry, or misplaced O-ring can cause a leak immediately after the repair.
- Follow the sequence and torque values: Dorman lists 9 lb-ft (12 N-m) for the housing bolts and cooler-to-housing bolts, 15 lb-ft (20 N-m) for the sensor or sensors, and 18 to 22 lb-ft (25 to 30 N-m) for the filter cap. Use the current instructions for your kit and application.
- Refill and inspect: Refill with the correct oil and coolant, bleed the cooling system when required, start the engine, and check for leaks and warning lights before driving.
Pro Tip: Place the supplied filter-update reminder where the next technician will see it. On a converted 2011-2013 engine, using the older filter style can create a service problem even when the housing itself was installed correctly.
Compatibility and Safety
The Dorman 926-959 is listed for select 3.2L and 3.6L Pentastar engines from the 2011-2026 model-year range, but that does not mean every Chrysler, Dodge, Jeep, Ram, or Volkswagen in those years uses this assembly. Your VIN-based catalog result or Dorman’s fitment tool should be the final check.
Use the oil grade and viscosity specified for your engine. The housing can work with conventional or synthetic oil, but the housing does not change the manufacturer’s oil specification. You should also inspect electrical connectors, sensor threads, hoses, and intake components during reassembly because damage in these areas can cause leaks, warning lights, vacuum leaks, or drivability issues.
Incorrect torque can be as harmful as a loose fastener. Overtightening the cap can damage it or shift the seal, while uneven housing-bolt torque can prevent the assembly from sealing flat. A qualified repair shop is the safer choice if you do not have a torque wrench, service information, or experience removing an intake manifold.
How It Performs in Real Use
For an Active Housing Leak
The kit gives you the main components needed to replace the housing and cooler together. That helps avoid reinstalling an old cooler or ordering parts separately. You still need to confirm whether the sensors are reusable and whether any oil-soaked intake seals, connectors, or hoses need attention.
For 2011-2013 Pentastar Engines
The newer filter design removes the early integrated bypass-valve arrangement. After installation, all future oil changes must use the later 2014-and-newer filter style, so the orange cap and reminder label are important service cues.
For Professional Shop Installation
A shop can verify the leak source, clean the engine valley, transfer or replace sensors, follow the bolt sequence, refill fluids, and scan for faults after the repair. Labor can be significant because access requires intake-system disassembly, but the complete kit reduces the number of major housing parts the shop must source.
For Long-Term Ownership
The aluminum design removes common plastic warping and plastic-weld failure modes. Long-term reliability still depends on genuine parts, correct seals, clean mating surfaces, accurate torque, the right filter, and routine inspection during oil changes.
Pros and Cons
Pros
- Fully cast aluminum housing replaces the main plastic failure point.
- Includes the oil cooler, filter, cap, mounting bolts, seals, and gaskets.
- Supports both early and later specified Pentastar generations.
- Uses machined sensor threads and a redesigned oil channel.
- Backed by a limited lifetime warranty and Dorman technical support.
Cons
- Fitment is limited and must be checked by exact vehicle details.
- Oil pressure and temperature sensors are not included.
- Installation is time-consuming and may be too advanced for a first repair project.
Is It Worth the Price?
The Dorman 926-959 sits above many generic aluminum housing kits, but the value comes from the patented design, documented testing, branded seals, complete cooler assembly, installation hardware, technical support, and limited lifetime warranty. It is worth considering when you want a more complete repair from an established aftermarket manufacturer.
The value is strongest when your existing housing has failed and your exact vehicle is confirmed. It is less attractive if you only need a cap seal, a sensor, or another small service part, since replacing the full assembly adds labor and parts cost that may not address the actual source of the leak.
How It Compares to Alternatives
The genuine Mopar 68596317AB is the factory-brand route for many later Pentastar applications and may appeal if you prefer original-equipment parts. The Dorman 926-959 focuses on an all-aluminum housing and a complete OE FIX package rather than repeating the original-style housing construction.
Dorman’s older 926-876 aluminum housing is the predecessor to this model. The 926-959 supersedes it and adds components for broader fitment and a more complete repair. Lower-cost unbranded aluminum assemblies may save money, but seal quality, machining, exact fit, warranty support, and authenticity can be harder to confirm.
Frequently Asked Questions
Does the Dorman 926-959 fit every Pentastar V6?
No. It fits select 3.2L and 3.6L Pentastar applications, but model-year and vehicle coverage vary. Confirm your year, make, model, trim, engine, and preferably VIN before ordering.
What comes in the Dorman 926-959 kit?
The package includes one aluminum oil filter housing, 19 seals and gaskets, five engine-mounting bolts, one filter cap, one oil cooler, and one oil filter. Oil pressure and oil temperature sensors are not included.
Which oil filter should I use after installing it on a 2011-2013 engine?
Use the later 2014-and-newer filter style specified by Dorman after the conversion. Install the supplied reminder label and keep the orange cap in place so future service technicians notice the filter change.
Which front oil-return O-ring should I install?
Dorman’s current instructions identify the 22.3 mm black O-ring for 2011-2021 applications and the 23 mm blue O-ring for 2022-and-newer applications. Lubricate it and follow the supplied instructions to avoid cutting or pinching the seal.
What are the Dorman 926-959 torque specifications?
Dorman lists 9 lb-ft (12 N-m) for the housing and cooler bolts, 15 lb-ft (20 N-m) for the sensors, and 18 to 22 lb-ft (25 to 30 N-m) for the cap. Always use the current instruction sheet and specified tightening sequence.
Can I use synthetic oil with this housing?
Yes, when synthetic oil meets the specification and viscosity required for your engine. The housing does not determine the oil type, so follow the vehicle manufacturer’s maintenance information.
Can a beginner install the Dorman 926-959?
It is not an ideal first repair because the intake manifold must be removed and several seals, connectors, sensors, and torque steps must be handled correctly. A qualified technician is a better choice if you lack service information or a calibrated torque wrench.
How can I identify an authentic Dorman 926-959?
Dorman advises buyers to look for the Dorman Wings cast into the housing. The authentic assembly also uses the distinctive orange filter cap, and buying from a reputable seller reduces the risk of receiving an unverified copy.
The Bottom Line
The Dorman 926-959 Oil Filter Housing is a well-designed repair choice for a confirmed 3.2L or 3.6L Pentastar application with a leaking or damaged factory-style housing. Its aluminum construction and complete cooler package are the main strengths, while narrow fitment, missing sensors, and a demanding installation are the main limitations. Skip it when the fitment is uncertain or the leak comes from another component.
