Q: How to replace the throttle body assembly on Chevrolet Express 3500?
A:
To replace the Throttle Body assembly one has to disconnect the negative Battery Cable as well as take off the engine cover, air cleaner outlet duct and cruise control cable along with the accelerator cable and the mounting bracket for both cables. Then remove the idle air control (IAC) valve harness connector and the throttle position (TP) sensor harness connector and remove the air cleaner adaptor stud and Throttle Body fasteners to remove the Throttle Body assembly and discard the flange seal. Clean the seal on the surface of Intake Manifold and set the Throttle Body assembly back into place using a new flange seal. Install Throttle Body assembly retaining fasteners using a torque of 25 n.m (18 lb ft), then use 8 n.m (71 lb in) for the air cleaner adaptor stud. Reconnect the tp sensor and iac valve harness connectors and reinstall the accelerator and cruise control cables and mounting bracket with good routing to avoid the throttle plate to be left open. Lastly, install the accelerator cable, the cruise control cable, the air cleaner outlet duct, and the engine cover and restore the negative cable of the battery. Check accelerator pedal for free operation without binding, press and release.
