  Q: How to replace the throttle body assembly on Chevrolet Avalanche 1500?

  A: To replace the Throttle Body assembly first we have to be careful with the electronic throttle control components, to avoid damaging it and do not use any min like small handtools to hold open the throttle plate as it might damage the wedge inside. Start with draining the cooling system partially to remove the hose at the Throttle Body. Then, take out the air cleaner outlet duct (lower down), as well as the engine sight shield. Drain the coolant air bleed hose using clamp, remove it from the Throttle Body, and reposition the throttle actuator motor electronic connector. Afterward, undo the Throttle Body nuts and follow these nuts to extract the Throttle Body and the gasket together but without the need to reuse the gasket. Install a new Throttle Body Gasket, the Throttle Body into place, and tighten the Throttle Body nuts to 10 n.m (89 lb in). Reattach the hose and its clamp for the coolant air bleed hose, connect the throttle actuator motor electrical connector, and check to make sure the connector and seal are in place and not damaged. Change engine sight shield and air cleaner outlet duct then top up the cooling system. Attach a scan tool to apply tests on throttle opening and throttle range closing to ensure that the accelerator pedal works properly from the closed to the wide open throttle (WOT). Check whether the vehicle is not in the reduced engine power mode, ignition is on, and engine is off just before starting the engine and checking for coolants leaks.
