When Your Engine’s Temperature Matters: Our Experience with the EVIL ENERGY Thermostat Housing Assembly
After three overheating incidents left us stranded on the side of Interstate 95 with our 2016 Dodge Charger, we knew it was time to address the failing OEM thermostat housing. As professional mechanics who’ve serviced Chrysler’s 3.6L Pentastar engines for over a decade, we’ve seen firsthand how quickly cooling system failures can escalate to catastrophic engine damage.That’s when we discovered the EVIL ENERGY Thermostat Housing Assembly (902-3035).
The moment we unboxed this replacement part, we noticed the notable attention to detail. Unlike other aftermarket options we’ve tried, this assembly came complete with everything needed for installation – thermostat, housing, gasket, adn even nitrile gloves (a thoughtful touch we appreciated during a messy coolant replacement). The housing’s construction felt significant, with none of the cheap plastic brittleness that tends to plague budget alternatives.
Installation on our customer’s Charger proved remarkably straightforward, with perfect fitment that matched the original equipment specifications. The housing’s design addressed several weak points we’d noticed in the factory part, particularly around the outlet neck where hairline cracks typically develop.
While we were initially skeptical about choosing a non-OEM solution for such a critical engine component, our extensive testing has revealed surprising performance that suggests this might be more than just another replacement part…
