2004 Chevrolet Corvette Throttle Body Parts Questions & Experts Answers

• Q: How to replace the throttle body assembly on 2004 Chevrolet Corvette?

  A: When you replace the Throttle Body assembly you should handle electronic throttle control components gently to protect them from damage by keeping them away from cleaning solutions and drops. A stored 8-digit part identification number stamped on the Throttle Body casting serves as a reference for servicing needs and future replacement tasks. Raise your vehicle before draining some coolant from the system to facilitate hose removal at the Throttle Body. Proceed with lowering the vehicle. Servicing requires that all openings should receive coverage and plugging to avoid contamination. Disconnect the intake Air Temperature Sensor electrical connector, remove the air intake duct then disconnect the air control valve and tp sensor electrical connectors as well as the crankcase ventilation hose from the Throttle Body. Start by disconnecting the coolant hoses and removing the Throttle Body attaching bolts then remove both the Throttle Body and gasket paying attention to dispose of the gasket materials rather than reusing it. Before reinstallation check the crankcase ventilation hose and tube for damage so you can replace failed parts. Installation commands for a new Throttle Body Gasket followed by coolant hose connection before assembly of the Throttle Body using a torque wrench to tighten bolts to 10 n.m (89 lb in). Connect the tp sensor electrical connector while ensuring that the crankcase ventilation hose remains aligned with proper electrical connector and seal placement and damage-free state. To complete the installation reconnect the electrical connector of the intake temperature sensor and refill the cooling system before confirming full throttle motion with a scan tool analysis during accelerator pedal operation. After initiating the engine operation check for any evidence of coolant leakage.
