Help your engine warm up and hold a steady operating temperature with the Motorad UltraStat Thermostat, part number 5416-180, a 180-degree unit built from heavy gauge stainless steel. It is listed for many models, among them the 2011-2023 Ram 1500, 2003-2010 Dodge Ram 1500 and 2021-2023 Jeep Wrangler, and it is a direct-fit replacement for the listed applications. See the "Vehicles it fits" section for the full list and engine details.
An engine coolant thermostat stays closed while the engine warms up, then opens near its rated temperature so coolant can flow to the radiator. Motorad's UltraStat line pairs that job with these features:
- Heavy gauge stainless steel: stainless steel components are used for increased reliability, durability and corrosion resistance.
- BLVT™ Valve Technology: Motorad's exclusive valve design is intended to minimize thermal shock to cooling system components.
- Stainless thermal element with REAX™ wax: the stainless steel thermal element resists corrosion, and the REAX™ wax mixture is designed for a quicker reaction time.
- AccuSpring™ Design: built for stable temperature control and improved cabin comfort.
Signs a thermostat may need replacing include engine overheating, slow warm-up or an engine that runs cold, weak heater output, or a temperature gauge that swings. These symptoms can have other causes, so diagnose the cooling system first. If a failed thermostat is the cause, this unit replaces it.
