  The Precision Pulse of Your Cooling System
  Your engine’s performance depends on reaching and maintaining an exact "sweet spot" of operating temperature. The Genuine Mopar Thermostat (52028898AJ)
   is a 195-degree (F) thermal gatekeeper engineered to provide surgical control over coolant flow. While aftermarket "economy" thermostats often use cheap wax elements that vary in quality and can fail to open, this genuine Mopar unit features a high-sensitivity thermal element designed to react instantaneously to fluctuating engine loads.

  • 195°F Calibrated Thermal Response: Engineered specifically for high-performance V8 architectures, this thermostat ensures the engine reaches its ideal 195°F operating temperature as quickly as possible. This minimizes the "cold-start" wear that accounts for the majority of engine friction.
  • Integrated High-Pressure Seal: This part number includes a factory-installed, precision-molded seal. Unlike universal gaskets that can pinch or weep over time, this integrated seal provides a permanent, leak-proof interface with the housing, even under the high-pressure conditions of a heavy-duty cooling system.
  • Anti-Corrosion Stainless Steel Construction: Fabricated from premium, heavy-gauge stainless steel, the 52028898AJ  is built to resist the scaling and mineral buildup common in older cooling systems. This ensures the internal piston and springs remain friction-free for years of reliable cycling.

  Why Choose Genuine Mopar?
  Choosing the Genuine Mopar Thermostat (52028898AJ)
   eliminates the risk of "false readings" and overheating caused by inaccurately sized aftermarket hardware. Many budget alternatives use smaller bypass valves that restrict total coolant volume, but this OE part is designed with a full-flow aperture to maximize cooling capacity when you need it most.

  • Integrated Air Bleed Valve: Genuine Mopar thermostats feature a specialized air-bleed (jiggle valve) to prevent air pockets from being trapped in the engine block. This prevents the localized "hot spots" that can lead to head gasket failure—a feature often missing from generic replacements.
  • The Final Engineering Revision: This part number (Revision AJ ) represents the most current factory-authorized design, incorporating improved metallurgy in the metal shroud and refined spring rates to replace and supersede all prior "AE" and "AI" versions.
  • Optimized Fuel Economy: By keeping the engine within its optimal thermal range, this sensor ensures the ECU maintains the correct air-fuel mixture, preventing the "rich-running" conditions and carbon buildup that degrade fuel efficiency and power output.
  • Factory-Backed Reliability: Every Mopar thermostat is backed by a Manufacturer-Backed Warranty. It undergoes rigorous thermal-cycle testing to ensure it will serve you reliably for miles to come, providing peace of mind that aftermarket "knockoffs" simply cannot match.
