Steps to Replace Dodge Neon Thermostat (1999-2005)

  1. Be sure the car is cooled down and not hot. If the car is hot the coolant will be under pressure and can burst out scalding anyone nearby.

    The thermostat is located on the left when looking into the engine compartment from the front. Place a pan under the car to catch any fluid that leaks out.

    I took out my thermostat in my dodge due to it over heating. Now it never over heats and it still blows out hot air. Anyone know why? Just found it out before a new one in

    What is the best way to clean the thermostat housing and the engine so it can seal properly. Is there a cleaner that needs to be used or do you just wipe it off till clean?
