Low Temp. Thermostat 180 Degree

The JET Performance Low Temp. Thermostat 180 Degree (MPN 10172) is engineered for Ford modular engine platforms from 1994–2005, delivering precise coolant flow control to optimize engine operating temperatures. Built for enthusiasts and mechanics who demand tighter thermal management, this 180-degree unit replaces restrictive OEM thermostats and enables your engine to maintain lower, more efficient running temperatures during sustained driving, track use, or high-performance modifications. When paired with upgraded cooling systems or forced-induction builds, a low-temperature thermostat minimizes heat soak and improves throttle response.

This JET Performance thermostat opens at 180 degrees Fahrenheit, compared to stock units that typically open at 190–195 degrees, allowing coolant to circulate more aggressively and shed heat faster under load. The low-temperature design reduces peak cylinder head temperatures, which is critical for naturally aspirated engines at high RPM and essential for turbocharged or supercharged builds where intake charge temperatures soar. Constructed to OEM specifications and sealed in a compact 4.75 x 2.2 x 5.5-inch housing weighing just 0.22 lbs, this thermostat integrates seamlessly into factory cooling passages without modification, ensuring reliability and longevity across thousands of miles.

Ideal for owners of 1994–2005 Ford Mustangs, F-150s, and Explorers running 4.6L, 5.4L, or other modular powerplants, this thermostat excels in street, weekend warrior, and competition environments. Installation is straightforward—remove the factory unit from the thermostat housing and drop in the JET Performance replacement with a fresh gasket. Pair it with a quality coolant, larger radiator, or electric fan upgrade for maximum benefit; alone, it provides measurable thermal improvement and works especially well on boosted platforms where conservative cooling temperatures prevent detonation and extend component lifespan.
