When Your Engine’s Heartbeat Depends on One Crucial Part
We’ve spent the past three months elbow-deep in engine compartments across our fleet of Dodge and Jeep vehicles, searching for a reliable solution to those frustrating coolant leaks and temperature regulation issues. After battling with OEM parts that seemed to fail prematurely, we decided to put the Allmotorparts Thermostat Housing Assembly 902-3312 to the test in our 2008 Jeep Grand Cherokee with the notorious 4.7L engine.
from the moment we unpacked this aftermarket replacement, we noticed the surprising quality of the materials-a welcome revelation for a part that endures such extreme temperature fluctuations. During installation on a especially humid Saturday afternoon, the precise fitment instantly stood out compared to other aftermarket options we’ve struggled with in the past. No more fighting with misaligned bolt holes or poor sealing surfaces.
What truly sets this thermostat housing assembly apart became evident during a recent 300-mile haul through the mountains with our 2005 Dakota. the temperature gauge remained rock steady even under load, a dramatic enhancement from the fluctuating readings and occasional overheating warnings we’d grown accustomed to. The peace of mind alone justified the investment.
Before revealing our complete findings on durability and long-term performance, we shoudl note that while this isn’t a genuine Mopar part, it might just offer something the factory version doesn’t. Let’s dive deeper into what makes this particular thermostat housing worth considering for your Chrysler, Dodge, Jeep or Ram vehicle.

We’ve thoroughly tested this thermostat housing assembly across the extensive compatibility list, and we’re impressed by its truly comprehensive coverage of Dodge and Jeep models. The housing fits perfectly on both 3.7L and 4.7L engines spanning over a decade of production.The fitment is remarkable across the 2000-2010 Dakota, 2000-2009 Durango, 2007-2011 Nitro, and 2002-2010 Ram 1500 in the Dodge lineup. For Jeep enthusiasts, we found equal compatibility excellence with the 2006-2010 Commander, 1999-2010 Grand Cherokee, and 2002-2012 Liberty models. This aftermarket replacement effectively crosses with OEM part numbers 902-3312, 53020887AC, and others, making it a reliable option for a wide range of vehicles.
Beyond the core Dodge and Jeep compatibility,the housing extends its utility to Chrysler’s 2007-2009 aspen,Mitsubishi’s 2006-2009 Raider,and even newer Ram vehicles including the 2011-2013 Ram 1500 and 2011 Ram Dakota. We installed this housing on a 2008 Grand Cherokee and a 2005 Dakota with equal success – both installations were straightforward with perfect bolt patterns matching the original parts. The gasket seated properly in both cases, creating a reliable seal that has shown no signs of leaking after several months of testing through varying temperature conditions.

Premium Construction and OE-Quality Performance
Engineered for excellence, this thermostat housing assembly showcases exceptional build quality that rivals OE specifications. We were impressed by the precision die-cast aluminum construction that provides superior corrosion resistance compared to plastic alternatives. The housing features reinforced mounting points that eliminate the flex and potential leakage points commonly found in lower-quality replacements. The integrated thermostat maintains precise operating temperature between 180-195°F depending on your specific engine submission, ensuring optimal engine performance across the wide temperature ranges experienced by jeep and Dodge vehicles.
The premium gasket material deserves special mention, as it creates a truly reliable seal that prevents the coolant leaks so common with aging OE housings. During our installation on a 2007 Jeep Grand Cherokee with the 4.7L engine, we noted perfect bolt pattern alignment and excellent thread quality that inspired confidence in the long-term durability of this component. Temperature regulation remained consistently within 2°F of factory specifications during our 500-mile test period, demonstrating this assembly’s ability to maintain proper engine operating temperatures across various driving conditions.

Installation Process and Troubleshooting Guide
Installing the Allmotorparts Thermostat Housing Assembly is straightforward for those with basic mechanical knowledge. We found the package includes everything needed for the job: the housing assembly, gasket, and necessary O-rings. The process takes approximately 45-60 minutes, depending on your vehicle model. First, ensure the engine is wholly cool before begining work.After draining the coolant (have a catch pan ready!), locate the existing housing between the engine block and upper radiator hose. The bolt pattern matches the OEM design perfectly, requiring a 10mm socket for most applications. We recommend applying a thin layer of RTV silicone to the gasket for added leak protection, though the included gasket generally provides an excellent seal on its own.
- Common installation issues and solutions:
- Coolant leaks after installation – Check for proper gasket alignment and bolt torque (14-16 ft-lbs)
- CEL codes after replacement – Ensure electrical connector is fully seated
- Difficulty removing old housing – Use penetrating lubricant and gentle tapping
- Air in system – follow proper bleeding procedure specific to your model
If you encounter persistent overheating after installation, verify that the thermostat was installed in the correct orientation-the spring side should face the engine. remember to refill with the manufacturer-recommended coolant mixture and properly bleed the cooling system to prevent air pockets.
