The thermostat is an meaningful Element of the Dodge and Plymouth Neon's cooling method. The thermostat helps frank the temperature of the engine by allowing another engine coolant to pass over the engine when it exceeds a sure temperature area. Provided the thermostat becomes stuck in the "frank" position, the engine Testament not be able to pleasant up quickly. Whether it fails in the "closed" position, the engine Testament overheat, causing catastrophic damage provided the thermostat is not replaced in continuance.


Removing the Old Thermostat

Refill the coolant system with fresh engine coolant. The small vent on the thermostat should be facing the 12 o'clock position. Place the thermostat housing over the thermostat. Reinsert the two mounting bolts and tighten them with a ratchet and socket.

8. Reattach the upper radiator hose to the thermostat housing. Position the retaining clip over the hose where it fits over the opening on the thermostat housing and tighten it with a flathead screwdriver. Attach the coolant overflow hose to the thermostat housing.

9.7. Place the O-ring on the mounting surface. Insert the new thermostat into the mounting area.

10. Reconnect the negative terminal cable to the battery and start the engine. Check the area underneath the passenger side of the engine and around the thermostat housing for any leaks. Monitor the Neon's coolant levels and add fresh coolant as necessary.
