Thermostat with Seal; 195-Degree (02-08 3.7L, 4.7L RAM 1500)Find parts that fit my vehicle

Optimal Engine Health. At the heart of every engine cooling system lies a delicate balance between heat management and mechanical performance. The Thermostat plays a crucial role in this balance by opening precisely at 195°F—an ideal temperature point that maximizes fuel vaporization and combustion efficiency while preventing premature engine wear.

Built to Last. Built for durability under the harshest of conditions, the Thermostat features a robust, heavy-gauge stainless steel frame designed to resist distortion, corrosion, and fatigue caused by extreme thermal cycling. Unlike lower-grade alloys that can warp or pit over time, this thermostat maintains its structural integrity and sealing capacity through repeated expansion and contraction.

Cooler, Quieter Operation. Integrating Motorad’s proprietary BLVT™ (Balanced Lift Valve Technology), the Thermostat sets itself apart with a smoother, more refined approach to coolant regulation. Traditional thermostats can cause sudden fluid surges when they open, which may result in pressure spikes and temperature fluctuations across the cooling system.

System-Wide Longevity. Thermal shock is an invisible threat that can take a serious toll on hoses, radiator seams, water pump gaskets, and engine block seals. The Thermostat helps combat this by transitioning gradually between open and closed states to prevent dramatic surges in coolant temperature and pressure.

Cleaner Starts and Smoother Driving. When engines run cold, combustion is less complete, oil is thicker, and friction increases—all of which degrade performance and emissions. The Thermostat restricts coolant flow during startup, allowing the engine to reach ideal operating temperature faster. This rapid warm-up reduces wear on internal components, minimizes emissions during cold cycles, and allows your heater core to deliver warm air to the cabin sooner.

The Unsung Hero. Fuel economy and emissions aren’t just determined by engine tuning—they rely on consistent engine temperature. The Thermostat ensures this thermal stability, helping modern fuel injection and emission systems operate within their target range. When engines are too cold, air-fuel ratios skew rich, and emissions skyrocket. Too hot, and pre-ignition or knock becomes a threat.

Installation. Putting this Thermostat with Seal; 195-Degree on your 3.7L, 4.7L RAM 1500 takes 5 minutes to install.

Warranty. There is a limited lifetime warranty on this product.
