Insert the key into the ignition and turn it to the "Run" position, then locate the release pin or screw on the ignition switch housing. Press the release pin while turning the key to the "Acc" position, and pull the ignition cylinder out. Finally, disconnect any wiring harnesses attached to the ignition switch if necessary.

To clean the throttle body on a 2004 GMC Envoy, first ensure the engine is off and cool. Remove the air intake duct to access the throttle body, then use a throttle body cleaner and a soft cloth or brush to gently scrub the inside surfaces, particularly around the throttle plate. Be cautious not to damage any components and avoid spraying cleaner directly onto the sensors. Once clean, reassemble the intake duct and start the engine to check for proper operation.

The thermostat on a 2002 GMC Envoy is typically located near the engine's front, where the upper radiator hose connects to the engine block. To replace it, first, drain the coolant, then remove the upper radiator hose and the thermostat housing cover. After removing the old thermostat, clean the mating surfaces, install the new thermostat with the correct orientation, and reassemble the housing and hose before refilling the coolant. Always ensure the cooling system is properly bled of air after the replacement.

The 2004 GMC Envoy typically comes with a sound system that includes six speakers. This includes front door speakers, rear door speakers, and a center channel speaker for enhanced audio quality. Depending on the trim level and options, some models may have an upgraded audio system with additional features.

The minimum rotor thickness for a 2002 GMC Envoy typically ranges around 1.05 inches (26.7 mm) for the front rotors and approximately 0.83 inches (21 mm) for the rear rotors. It's important to check the vehicle's service manual for specific details, as these values can vary slightly based on the specific model and brake system. Always ensure that rotors are inspected regularly and replaced if they are below the minimum thickness to maintain safe braking performance.

To drain the gas tank on a 2003 GMC Envoy, first ensure the vehicle is on a level surface and the engine is off. Locate the fuel pump relay in the fuse box and remove it to prevent the fuel pump from activating. Disconnect the fuel line from the fuel filter or rail, using a fuel line tool if necessary, and direct the line into a suitable container to catch the fuel. Finally, you can siphon any remaining fuel from the tank using a siphon pump or a similar tool. Always follow safety precautions when handling fuel.
