Product Description

The Mishimoto MMTS-RB-ALLL Racing Thermostat is a performance cooling upgrade engineered for a broad range of Nissan, Infiniti, and Mercury vehicles powered by V6 engines such as the VG30 and 3.3 L V6 platforms. By activating coolant flow at approximately 154.4 °F (68 °C), this thermostat allows the cooling system to circulate coolant earlier than many stock units, helping to reduce peak engine temperatures and maintain more consistent thermal control during spirited driving, towing, or high-ambient conditions.

Designed as a direct replacement for the factory thermostat, the MMTS-RB-ALLL fits into the original housing without modification and offers reliable performance across a range of compatible vehicles including the Nissan 300ZX, Maxima, Pathfinder, Frontier, Infiniti J30/M30/QX4, Nissan Quest and 200SX, and Mercury Villager. Backed by Mishimoto's Lifetime Warranty, this thermostat is ideal for enthusiasts or daily drivers seeking more stable engine temperatures and improved cooling efficiency.
