This NTY CTM-BM-036 kit provides a comprehensive solution for your vehicle's cooling system. It includes both the main engine thermostat and the EGR (Exhaust Gas Recirculation) thermostat, both integrated with their respective housings. Proper functioning of the thermostat is crucial for maintaining the optimal operating temperature of your engine. This prevents overheating, which can lead to severe damage, and also ensures efficient fuel combustion and emissions control. The inclusion of the EGR thermostat addresses the recirculation of exhaust gases, a key component in reducing NOx emissions. A properly working EGR thermostat helps the system function as designed, contributing to cleaner exhaust. NTY parts are designed to meet or exceed original equipment specifications, offering a reliable replacement for your worn or faulty components. This kit simplifies the replacement process by providing both essential thermostats and their housings together.
