Upgraded Aluminum Thermostat Housing: A Lifesaver for Chrysler & Dodge 3.6L Engines

We recently got our hands on this aluminum thermostat housing assembly, and we’re pleased to report it’s a significant upgrade over the OEM plastic version. After testing it on a 2015 Dodge Charger with the 3.6L engine, we noticed immediate improvements in coolant flow regulation. The aluminum construction addresses the common failure point of the factory plastic housing, which tends to crack or warp over time, especially in warmer climates.

What impressed us most was the precision fit – it’s a direct replacement for part number 902-3035HP, requiring no modifications for installation. The included gasket and hardware made the swap straightforward, taking us about an hour with basic tools. For Chrysler 300, Challenger, and Charger owners experiencing cooling system issues or preventatively upgrading, this housing offers peace of mind and potentially saves hundreds in future repairs.
