How to Maintain a Coolant Temperature Sensor on a 5.7L Engine on Dodge Ram 2500?

When servicing the Coolant Temperature Sensor/Switch for the computer on a 5.7L engine, first start draining its coolant to ensure it is not pressurized and can't hurt you. After that, take the accessory drive belt off and unhitch the air conditioning compressor from the front of the engine, but don't disconnect any hoses beforehand. Gently hold up the compressor to get to the ECT sensor (3). Take out the electrical connector from the sensor, then remove the sensor from the block.

How to Service a Coolant Temperature Sensor on Dodge Ram 2500?

First, release part of the coolant from your car to avoid possible injury while working on the Engine Coolant Temperature (ECT) Sensor. After that, take out the air cleaner assembly and unplug the electrical connector from the sensor. For engines that have air conditioning, utilize a fabricated L-shaped hook from a coat hanger, around eight inches long, to pull the connector slowly; the hook allows you to remove the connector from the sensor, as it's held on without a lock type tab. Once you've disconnected everything, remove the sensor from the intake manifold. Before anything else, install the sensor and fasten it to a 6-8 Nm (55-75 in. lbs.) torque. Then, link the electrical connector to the sensor, paying attention that the connector fits both left and right ways, so you can connect it either side up. Lastly, put the air cleaner assembly back into place and replace all missing coolant.
