Mishimoto Thermostats

Mishimoto thermostats are effective in noticeably lowering engine coolant temperatures. These thermostats are built with high-quality wax and are shipped with new rubber gaskets (where applicable) for a good, leak-free seal. They are then digitally calibrated for precise operation. Mishimoto thermostats open up at a slightly lower temperature than OEM or standard thermostats once your engine is fully warmed up. This allows the coolant to flow through the engine sooner, thus reducing and maintaining cooler engine temperatures. Whether you have a daily driver or a modified and upgraded turbo, Mishimoto thermostats will maintain optimal temperatures to efficiently cool your application.

Mishimoto Performance Radiator Essentials Bundles

Restore and enhance your cooling system with a Mishimoto Performance Radiator Essentials Bundle. The bundles include high-quality upgraded cooling components to replace items Mishimoto found to be the most failure-prone. Kits feature an aluminum radiator, silicone radiator hose kit, high- and low-temperature thermostats—plus other components (depending on the bundle you select). The Performance radiator features full aluminum construction with durable TIG-welded end tanks. In addition, it's designed with a massive two-row 2.2 in. thick core, which provides substantial improvements in cooling efficiency. The radiator hose kit is constructed from four layers of silicone with heat-resistant embedded fibers. This combination of materials provides substantially improved heat and pressure tolerance compared to the stock rubber hoses. In addition, the kit includes a CNC-machined aluminum quick-disconnect fitting, providing a considerable improvement in durability over the stock plastic unit. Rounding out the basic Essentials Bundle is a pair of thermostat sets; high-temperature thermostats hasten engine warmup, making it ideal for use in cold climates. The low-temperature thermostats have a lower activation temperature compared to the factory thermostat. Lower activation temperature allows coolant to flow through the engine earlier, reducing the risk of overheating in hot environments. Order the bundle with components preferred for your vehicle.
