This allows coolant to flow through sooner, helping to reduce and maintain cooler temperatures in the engine. This is also a great addition to vehicles with upgraded radiators and fans.  RAM 6.4L ENGINE ONLY Fits the following vehicles: 2007 - Current: RAM 1500 6.4L only (note: early 2007 vehicles might have a gen III engine, not compatible)  RAM 2500, 3500, 4500 vehicles (6.4L engine only)   Pro Tips: Engine Cooling Service: We recommend replacing the thermostat and flushing the cooling system every 45,000 miles or every 4 years.
