Where can I install a Water Temperature on a 2000-2006 Silverado/Sierra with a 4.8/5.3/6.0 Gas Engine?

On the 2000-2006 Silverado/Sierra 4.8/5.3/6.0 Liter engines there is a coolant port on the cylinder head. Once the coolant port plug is removed, you can install our Water Temperature Sensor Thread Adapter for LS Engines. This adapter will allow you to install the provided Glowshift Water Temperature sensor into your 4.8/5.3/6.0 Liter engine.
