  A: You must first drain the engine coolant before starting throttle body service and repair operations. Service and repair work on the throttle body starts with disconnecting the accelerator cable followed by removing the air cleaner hose and cap through the process of unboltting the 2 air cleaner hose clamp bolts and separating the hose from the throttle body and air cleaner cap. The authorization to remove the throttle body begins with disconnecting the throttle position sensor connector and IAC valve connector and PCV hose and both water bypass hoses. First detach the bolt and 2 nuts and remove the intake manifold accelerator bracket also removing the throttle body from the system and taking away the throttle body gasket. The first step for installation requires mounting the throttle body with its accelerator cable bracket through a bolt followed by two nuts while maintaining a torque of 30 N.m (305 kgf.cm, 22 ft.lbf). Attach the throttle body to its components through water bypass hose pairs as well as IAC valve connector and throttle position sensor connector and PCV hose pair. Finish by installing the air cleaner hose with its cap before proceeding to refill the engine coolant inside the radiator.
