Improve the reliability of your 5.9L\/6.7L cooling system with a Mishimoto Dodge 5.9L\/6.7L Cummins Low-Temperature Thermostat! This thermostat is designed as a direct-fit replacement for your aged factory unit. The Mishimoto thermostat has a lower activation temperature (180 degrees Fahrenheit) compared to the factory thermostat (190 degrees Fahrenheit for 99-10 and 2013 trucks and 200 degrees Fahrenheit for 10-12 trucks). The lower activation temperature allows coolant to flow through the engine earlier, which reduces and maintains lower engine temperatures. This thermostat is ideal for use in warmer climates or under extreme towing\/driving conditions. As with all our products, this thermostat includes the Mishimoto Lifetime Warranty, ensuring superior product quality and craftsmanship.\nEngine coolant thermostat designed to regulate coolant flow and maintain optimal operating temperature. Ensures efficient warm-up, prevents overheating, and supports reliable performance with a precise fit.\n1999-2001 Dodge Ram 1500 Laramie 5.9 Liter 42RE, 2003 Dodge Ram 1500 Laramie 5.9 Liter 45RFE, 1999-2001 Dodge Ram 1500 Laramie 5.9 Liter 46RE, 2003 Dodge Ram 1500 Laramie 5.9 Liter 46RE, 1999-2001 Dodge Ram 1500 Laramie 5.9 Liter NV3500, 2003 Dodge Ram 1500 Laramie 5.9 Liter NV3500, 1999-2001 Dodge Ram 1500 Laramie 5.9 Liter NV4500, 2003 Dodge Ram 1500 Laramie 5.9 Liter NV4500, 2002-2003 Dodge Ram 1500 SLT 5.9 Liter 45RFE, 2002-2003 Dodge Ram 1500 SLT 5.9 Liter 46RE, 2002-2003 Dodge Ram 1500 SLT 5.9 Liter NV3500, 2002-2003 Dodge Ram 1500 SLT 5.9 Liter NV4500, 1999-2001 Dodge Ram 1500 Sport 5.9 Liter 42RE, 1999-2001 Dodge Ram 1500 Sport 5.9 Liter 46RE, 1999-2001 Dodge Ram 1500 Sport 5.9 Liter NV3500, 1999-2001 Dodge Ram 1500 Sport 5.9 Liter NV4500, 1999-2001 Dodge Ram 1500 ST 5.9 Liter 42RE, 2002-2003 Dodge Ram 1500 ST 5.9 Liter 45RFE, 1999-2003 Dodge Ram 1500 ST 5.9 Liter 46RE, 1999-2003 Dodge Ram 1500 ST 5.9 Liter NV3500, 1999-2003 Dodge Ram 1500 ST 5.9 Liter NV4500, 2003 Dodge Ram 2500 5.9 Liter 45RFE, 1999-2003 Dodge Ram 2500 5.9 Liter 46RE, 1999-2003 Dodge Ram 2500 5.9 Liter 47RE, 2003-2009 Dodge Ram 2500 5.9 Liter 48RE, 1999-2005 Dodge Ram 2500 5.9 Liter NV4500, 1999-2004 Dodge Ram 2500 5.9 Liter NV4500HD, 1999-2005 Dodge Ram 2500 5.9 Liter NV5600, 1999-2002 Dodge Ram 2500 Base 5.9 Liter 46RE, 1999-2002 Dodge Ram 2500 Base 5.9 Liter 46RE, 1999-2002 Dodge Ram 2500 Base 5.9 Liter 47RE, 1999-2002 Dodge Ram 2500 Base 5.9 Liter 47RE, 1999-2002 Dodge Ram 2500 Base 5.9 Liter NV4500, 1999-2002 Dodge Ram 2500 Base 5.9 Liter NV4500, 1999-2002 Dodge Ram 2500 Base 5.9 Liter NV4500HD, 1999-2002 Dodge Ram 2500 Base 5.9 Liter NV4500HD, 1999-2002 Dodge Ram 2500 Base 5.9 Liter NV5600, 1999-2002 Dodge Ram 2500 Base 5.9 Liter NV5600, 2005-2007 Dodge Ram 2500 Laramie 5.9 Liter 48RE, 2005-2007 Dodge Ram 2500 Laramie 5.9 Liter 545RFE, 2007 Dodge Ram 2500 Laramie 5.9 Liter 68RFE, 2005-2007 Dodge Ram 2500 Laramie 5.9 Liter G56 ...See Application Guide for Additional Fitments\n\u003cul\u003e\n  \u003cli\u003eActivates at lower temperature so coolant flows through system earlier\u003c\/li\u003e\n  \u003cli\u003eAllows for cooler engine temperatures\u003c\/li\u003e\n  \u003cli\u003eIdeal for warm climates\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eEnsure optimal engine temperature regulation and prevent overheating issues with the Mishimoto Dodge 5.9L\/6.7L Cummins Low-Temperature Thermostat.
