2004 Chevrolet Astro Parts Questions & Experts Answers

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

  A: Begin the Throttle Body assembly replacement process by discharging the negative Battery Cable followed by the engine cover and air cleaner outlet resonator and adapter stud removal. First detach the cruise control cable and accelerator cable before you remove the stud and nuts from the accelerator control cable bracket so you can place the bracket aside. First disconnect both (IAC) valve harness connector and (TP) sensor harness connector and remove the two Throttle Body retaining studs while throwing away the Throttle Body seal. After cleaning the Intake Manifold gasket surface install the Throttle Body assembly using a fresh seal. First institute the Throttle Body assembly retaining studs at 9 nm (80 lb in.) torque levels before securing the air cleaner outlet resonator adapter stud at 8 nm (71 lb in.). Connect the tp sensor harness to its connector and iac valve harness connector before installing the accelerator control cable bracket using 12 nm (106 lb in.) fasteners that maintain proper cable position and avoid throttle restriction. The procedure continues with parallel installation of the accelerator cable and cruise control cable and air cleaner outlet resonator before engine cover installation and negative Battery Cable reconnection. Release the accelerator pedal until reaching the floor board before observing free movement while keeping pedal usage between full throttle and full stop position.
