Water Temp Sensor

[T-top87GN]

Does anyone know the part number for the water temp sensor that goes in the driver side of the block near the back? And while we're at it, the part number for the upper plenum?

Would Autozone/Advanced have these?

Thanks!

Not sure, but I doubt these are available at Auto Zone, etc.

Parts book shows:

Upper intake 25525146 (gmpartsdirect shows availability) - approx. $54.00
*Coolant temp switch 25036371 (1 blade) - gmpartsdirect - $6.40
*Coolant temp switch 25036979 (2 blade)

*"water temp sensor that goes in the driver side of the block near the back?"
Not sure you're referring to the coolant temp sensor??

Hope this helps in some way....

CTS from Auto Zone = part # SU109
This is the temp SENSOR that comunitcates with the ECM (2 wire plug I believe). Not the temp switch that sends signal to the idiot light which is the one that is taken out when adding a water temp gauge.

P.S. its a normal stock item. Its a more common piece than you may think (i.e. same part used for 3800 front wheel drive GM).
