On a 1998 Oldsmobile aurora where is the engine coolant sensor located?

The exact location of the engine coolant temperature sensor (ECT) on a 1998 Oldsmobile Aurora depends slightly on the engine type (3.5L or 4.0L). However, it's generally found on the engine block, near the thermostat housing.

It's a small sensor, often with a single or two-wire connector. You'll likely need to consult a repair manual specific to your 1998 Oldsmobile Aurora's engine to pinpoint its precise location. A diagram in the manual will be invaluable.

To help you find it:

* Visual Inspection: Look around the thermostat housing and the area of the engine block immediately surrounding it. The sensor might be mounted directly into the block or into a fitting near the housing.

* Repair Manual: A Haynes or Chilton repair manual for your specific year and model will have diagrams showing the exact location of all sensors, including the ECT.

* Online Resources: Websites like AutoZone or Advance Auto Parts allow you to enter your vehicle's information and sometimes access diagrams that may show the sensor location.

Remember to be careful when working near hot engine components. Let the engine cool completely before attempting any work.
