Setting limits – Replacing the thermostats on a 2.4L 2014 Chrysler 200

Less than 20 miles after driving off the used car lot, my new (to me) 2014 Chrysler 200 LX gave me an engine code of P0128, “Coolant Thermostat (Coolant Temperature Below Thermostat Regulating Temperature).” The most common causes for this are a bad coolant temperature sensor or a bad thermostat. After replacing the coolant temperature sensor didn’t fix my problem (   • Don’t lose your cool – replacing cool...  ), I knew I needed to replace a bad thermostat.

In the 2.4L Dual VVT Chrysler 200, there are actually two thermostats and a thermostat housing. This video shows how to replace the entire housing since I didn’t want to guess at which thermostat was broken and replace the wrong one (and end up having to drain the coolant twice).

Since I had to drain the coolant to replace the thermostat, I also replaced the radiator petcock/drain valve since it’s also been leaking slowly.

This will apply to many other years, makes, and models that have this 2.4L engine.
