To find the coolant temperature sensor for a 2013 Dodge Ram 3.6 liter truck, look around the cylinder head on the driver's side near the firewall. The sensor is a metal cylinder, roughly 3 inches long, with threads and a narrower end. If you need to replace it, there are tutorials available for a DIY approach. However, if you prefer taking it to a repair shop, expect to pay between $100 and $115 for parts and labor. A faulty coolant sensor can lead to engine temperature spikes, reduced fuel efficiency, black smoke from the exhaust, rough idling, coolant leaks, and an illuminated "check engine" light. Failing to address the Engine Coolant Temperature (ECT) sensor can impact fuel mixture, emissions, and overall performance of the vehicle.
