Detailed Description

Motorad Standard 422-190 is an engine coolant thermostat engineered to match OEM specifications and processes. The copper case and wax element are selected to react quickly as coolant temperature rises and falls, helping the engine reach and maintain the intended operating range. The 192°F opening temperature aligns with OE-specified applications, including 2001-2005 Chrysler Sebring, 2001-2005 Dodge Stratus, 2000-2005 Mitsubishi Eclipse, 1999-2003 Mitsubishi Galant, and 2003 Mitsubishi Outlander.

This part cross-references Gates 42290 and Stant 48239 for the same application. The Motorad 422-190 is a direct-fit thermostat choice for drivers replacing a worn or sticking unit in these vehicles.

What This Thermostat Helps Address

• Engine running too cool or too hot due to thermostat wear
• Delayed warm-up after cold starts
• Temperature fluctuation from a thermostat that opens inconsistently
• Coolant flow control issues caused by a sticking valve
• Service leaks at the thermostat seal or housing interface

Installation Notes and Tips

Verify the OE-specified temperature before installation and confirm the housing and sealing surfaces are clean. The included rubber O-ring seal should be seated evenly, and the jiggle pin weep hole should be oriented to help purge trapped air during refill. This thermostat is a standard replacement part for the listed Chrysler, Dodge, and Mitsubishi applications.
