  Q: How to replace the lower intake manifold on Chevrolet Venture?

  A: To remove the lower Intake Manifold, you will need the following tools: torque angle meter (J 36660-A). Start with the upper Intake Manifold removal, followed by removal of engine left and right side valve rocker arm covers. Separate the lead from the engine coolant temperature (ECT) sensor, making sure to tag the power of every injector metal lead connector with masking duct tape for easy identification. Next, quite the Fuel Injector, manifold air pressure (MAP), and the ect wiring harness, remove the fuel feed and the return pipe from the Fuel Injector rail, as well as the Fuel Injector rail itself. It is recommended that one should not detach the power steering pipes or hoses from the Power Steering Pump, instead remove the Power Steering Pump from the front engine cover and place it on the side. Remove the heater inlet pipe with heater hose and the inlet Radiator Hose from the engine; the thermostat bypass hose may be removed from the lower Intake Manifold pipe as well.
