The replacement process for an Intake Manifold starts by disconnecting the negative cable from the battery and draining the cooling system. Disconnect both the accelerator cable and the throttle valve (TV) cable from the
Throttle Body before removing the iat sensor connector from the air cleaner and its hose from the Throttle Body. Begin by disconnection of throttle position (TP) sensor connector and idle air control (IAC) valve connector along with manifold absolute pressure (MAP) sensor connector and two coolant bypass hose clamps and the coolant bypass hoses from Throttle Body after removing air cleaner top assembly. Remove the three bolts securing the fuel injector wiring harness from positions 3 and 4. Then detach this wiring harness from the Intake Manifold. Pull out the bolts that anchor the support bracket after removing both the support bracket itself. Start by disconnecting the upper
Radiator Hose at its radiator connection before relocating that hose to the side. Remove the upper Radiator Hose support bracket bolt and the nut while also discarding the Intake Manifold bolts. Use the socket set to remove the top hose support bracket then disconnect the three rubber hoses operating at the Intake Manifold. Remove the two injector harness support brackets before correctly extracting the Throttle Body with the Intake Manifold off the Cylinder Head. To fit the parts place a new Intake Manifold Gasket and the Intake Manifold with Throttle Body onto the Cylinder Head while securing it with 3 nuts along with 2 bolts which must be tightened up to 18 nm (13 ft. Lbs.). Complete the installation by placing the upper Radiator Hose support bracket and reattaching both injector harness support brackets before connecting the three vacuum lines. Use two bolts to attach the Intake Manifold support bracket where tightness must reach 18 nm (13 ft. Lbs.). Reattach the fuel injector wiring harness with three bolts (3, 4) tightened to 12.7 nm (9 ft. Lbs.), connect the four fuel injector connectors, and then reconnect the Throttle Body components: the correct installation of a new volvo xc90 requires connecting the throttle position (TP) sensor connector and idle air control (IAC) valve connector and manifold absolute pressure (MAP) sensor connector while securing two coolant bypass hose clamps and coolant bypass hoses. The repair process includes fitting the air cleaner top assembly followed by hose connection to the Throttle Body and sensor connector reattachment of intake air temperature (IAT). Install the throttle valve (TV) cable and the accelerator cable to the Throttle Body before completing the process by adding fluid to the cooling system as needed and securing the negative
Battery Cable by tightening its bolt to 15 nm (11 ft. Lbs.).
