EVIL ENERGY Thermostat Housing: Cooling Salvation for Chrysler and Dodge 3.6L Engines
When â˘Your Engine’s âŁTemperature Matters: Our Experience with the⤠EVIL ENERGY Thermostatâ Housing Assembly
After three â˘overheating âincidents left âus 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 â˘3.6L Pentastar⣠engines for over a decade, we’ve seen firsthand how quickly⢠cooling system failures⣠can âescalate to⢠catastrophic engine damage.That’s when we discovered the EVIL ENERGY Thermostat Housing Assembly (902-3035).
The moment we unboxed â˘this replacement part, âwe noticed the notable attention to detail. Unlike other aftermarket⢠options we’ve tried, thisâ assemblyâ 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 theâ cheap plastic brittlenessâ that tends to plague âbudget alternatives.
Installation onâ our customer’s Charger proved remarkably straightforward, with perfect fitment that matched the original equipment specifications. The housing’sâ 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 aboutâ choosingâ a non-OEM solution for such a critical â˘engine component, our extensive testing has revealed surprising performance that suggests this might be more than just⢠another replacement part…
