I need the location for a coolant sensor on a 04 chevy silverado truck

You didnt say what size of engine you had, but in 5.3L the coolant temp sensor is located on the driver's side of the engine, just in front of the exhaust manifold. If you have a different engine, just leave a comment on here and i will update the location.

My service 4wd scan comes on. any idea what that

It is called the solenoid sensor, it can keep the truck in a different gear than is shown on transfer case switch. This happened on my chev as well but it wasn't the sensor just a corroded ground cable for the solenoid sensor.
