Where's my temperature cooling sensor located at on my 2003 oldsmobile Alero quad motor? Also, do I need to drain my radiator fluid first before doing anything else?

Your Alero does not have a transmission dip stick. You do not need to check it unless it starts leaking.


Please let me know if this information is helpful. Positive feedback is appreciated. Thank You!

HI there if the scan tool you are using will not reprogram the theft module the try the 10 min relearn

1. Turn ON the ignition, with the engine OFF.
2. Attempt to start the engine, then release the key to ON (vehicle will not start).
3. Observe the SECURITY telltale, after approximately 10 minutes the telltale will turn OFF.
4. Turn OFF the ignition, and wait 5 seconds.
5. The vehicle is now ready to relearn the Passlock™ Sensor Data Code and/or passwords on the next ignition switch transition from OFF to CRANK. Important: The vehicle learns the Passlock™ Sensor Data Code and/or password on the next ignition switch transition from OFF to CRANK.

SOURCE: Where is the radiator drain plug for a oldsmobile

The radiator drain plug is on the lower left front (drivers side) of the radiator. To access it you may have to remove the front air dam. It is a white plastic plug and requires a Torx socket to loosen (sorry but not sure of the exact size of the Torx socket). Insert Torx and turn counter clockwise a half turn. Pull the plug out using a pliers until fluid begins to drain. Be careful because this is a plastic plug and may break easily. When fluid is finished draining simply push the plug in and turn clockwise half a turn with the Torx socket to secure.
