How to remove the throttle body on Chevrolet Express?

To remove the throttle body, relieve fuel system pressure and disconnect the negative battery terminal. Remove engine cover and disconnect electrical connector from throttle body. Disconnect fuel supply and return lines, remove bracket bolt, and loosen nuts attaching fuel lines to throttle body. Remove throttle body, accelerator cable bracket, ignition coil/module assembly, and EVAP canister purge solenoid. Carefully remove upper intake manifold and detach poppet nozzles from intake manifold. Pry bracket locking tabs away from throttle body and remove assembly. Remove fuel injector hold-down plate nuts and plate, then push injector out of throttle body. For installation, replace injector O-rings and apply light coat of clean engine oil before pressing injector into throttle body. Install injector hold-down plate and nuts, then install throttle body onto intake manifold bracket. Install poppet nozzles and ensure they are properly seated. Inspect and replace seals if necessary, then install upper intake manifold, EVAP purge valve, and ignition coil/module assembly. Inspect and replace damaged fuel line O-rings and retainers, then install fuel lines and bracket. Install throttle body with new gasket. Remaining steps are reverse of removal. Finally, activate fuel pump by turning ignition switch to ON and check for fuel leakage in fuel lines and throttle body.

What is the purpose of the carburetor or Throttle Body on Chevrolet Tracker?

The carburetor or TBI unit used on earlier models is attached to the top of the intake manifold by several bolts or nuts. These fasteners can sometimes work loose from vibration and temperature changes during normal engine operation, causing a vacuum leak. If a vacuum leak is suspected at the bottom of the carburetor or throttle body, a two-foot length of fuel line hose can be used. Start the engine and place one end of the hose next to your ear while probing around the base with the other end. A hissing sound will indicate a leak, but be careful of hot or moving engine components. The air cleaner assembly should be removed, with each disconnected hose tagged with a piece of numbered tape for easier reassembly. The mounting nuts or bolts at the base of the carburetor or throttle body should be located, and any necessary special tools or adapters identified. These nuts or bolts should be tightened to the torque, but not over tightened to avoid stripping the threads.

Chevrolet Throttle Body Parts Questions & Experts Answers

Throttle Body Assembly (W/ Throttle Actuator)

Q: How to remove the throttle body on Chevrolet Express?
A: To remove the throttle body, relieve fuel system pressure and disconnect the negative battery terminal. Remove engine cover and disconnect electrical connector from throttle body. Disconnect fuel supply and return lines, remove bracket bolt, and loosen nuts attaching fuel lines to throttle body. Remove throttle body, accelerator cable bracket, ignition coil/module assembly, and EVAP canister purge solenoid. Carefully remove upper intake manifold and detach poppet nozzles from intake manifold. Pry bracket locking tabs away from throttle body and remove assembly. Remove fuel injector hold-down plate nuts and plate, then push injector out of throttle body. For installation, replace injector O-rings and apply light coat of clean engine oil before pressing injector into throttle body. Install injector hold-down plate and nuts, then install throttle body onto intake manifold bracket. Install poppet nozzles and ensure they are properly seated. Inspect and replace seals if necessary, then install upper intake manifold, EVAP purge valve, and ignition coil/module assembly. Inspect and replace damaged fuel line O-rings and retainers, then install fuel lines and bracket. Install throttle body with new gasket. Remaining steps are reverse of removal. Finally, activate fuel pump by turning ignition switch to ON and check for fuel leakage in fuel lines and throttle body.

Q: What is the purpose of the carburetor or Throttle Body on Chevrolet Tracker?
A: The carburetor or TBI unit used on earlier models is attached to the top of the intake manifold by several bolts or nuts. These fasteners can sometimes work loose from vibration and temperature changes during normal engine operation, causing a vacuum leak. If a vacuum leak is suspected at the bottom of the carburetor or throttle body, a two-foot length of fuel line hose can be used. Start the engine and place one end of the hose next to your ear while probing around the base with the other end. A hissing sound will indicate a leak, but be careful of hot or moving engine components. The air cleaner assembly should be removed, with each disconnected hose tagged with a piece of numbered tape for easier reassembly. The mounting nuts or bolts at the base of the carburetor or throttle body should be located, and any necessary special tools or adapters identified. These nuts or bolts should be tightened to the torque, but not over tightened to avoid stripping the threads.
