  Q: How to service and repair the Air Injection Pump on Toyota Land Cruiser?

  A:

  The service and repair of the Air Injection Pump demands an initial step of fuel system pressure discharge and negative battery terminal cable disconnection for at least 90 seconds to stop Air Bag and seat belt pretensioner activation. You should drain the engine coolant then take out the V-bank cover sub-assembly before cutting the fuel return and main hoses. Service the Air Injection System by beginning with intake air connector pipe and Intake Manifold assembly removal and finally removing the vacuum control valve set through disconnection of the 2 bolts and valve set from the intake manifold along with the 2 vacuum hoses. Begin air pump assembly removal by disconnecting No. 2 air hose and air switching valve connector and pressure sensor connector before removing its securing 4 bolts. To remove the No. 2 air switching valve proceed by removing 4 nuts combined with 2 gaskets and disconnecting 2 No. 3 air tubes from the Exhaust Manifolds. Then install the 4 bolts alongside 2 gaskets and 2 No. 3 air tubes on the 2 No. 2 air switching valves. Additional steps involve removing the 4 bolts with 2 gaskets and 2 No. 2 air switching valves from the rear water by-pass joint followed by uninstalling 2 vacuum hoses from the No. 2 air switching valves. Disconnect both connectors from the air injection control driver followed by removing its two bolts. Start by attaching the air injection control driver into position with its two bolts torqued to 19.5 N.m before linking the two connectors. The process starts by connecting the vacuum hoses to No. 2 air switching valves before placing new gaskets and installing the valves to the rear water by-pass joint with 4 bolts at 10 N.m torque. Afterward, secure the No. 3 air tubes to the exhaust manifold with 4 nuts at 10 N.m torque. Insert the air pump assembly using 4 bolts which need a torque of 16 N.m. Also reinstall the pressure sensor connector and the air switching valve connector and the No. 2 air hose. Fasten the vacuum control valve onto the intake manifold via 2 bolts while tightening it to 7.5 N.m and proceed to connect both vacuum hoses. You should reinstall the intake manifold assembly after connecting the fuel main and return hoses together with the intake air connector pipe as well as the V-bank cover sub-assembly. Reconnect the cable to the negative battery terminal and perform initialization during which specific systems must be initiated apart from reconnecting the cable. After this you should add engine coolant while checking for both engine coolant and fuel leaks.

  Q: How to install the air injection pump assembly on Toyota Land Cruiser?

  A:

  The air injection pump assembly installation requires attaching 6 air pump insulators to the air pump bracket before securing it to the bracket and connecting 2 wire harness clamps to the bracket. Attaching the hoses to the air pump requires proper alignment of their ends with the stoppers. The air pump inlet must be connected to 2 No. 1 air injection system hoses through the stopper ends until alignment occurs before tightening 2 bolts to 8.0 Nm (82 kgf-cm, 71 in-lbf). Fasten the air pump assembly together with the bracket by sliding the bracket tab into the first slot allowing a stud bolt into the bracket hole followed by placing the bracket into the second slot before applying two bolts and two nuts at 18 Nm (184 kgf-cm, 13 ft-lbf) torque. The 2 air pump connectors need to connect while the 3 wire harness claws should attach. When you connect the No. 3 air injection system hose it must face towards the air pump rib while the clamp direction remains proper before clamping the hose onto the No. 3 pipe and fastening the bracket clip with paint marks aligned to the clamp edge. Position the paint mark of the No. 3 hose facing upward before connecting the hose to the air tube. Confirm proper hose clamp positioning before fixing the clamp on the No. 3 hose and wire harness to the body hole using the clip. The No. 2 air injection system hose requires proper paint mark alignment with the air pump rib before placing the clamp correctly and attaching it to the air tube with paint mark facing upward and clamp in position. When installing the No. 2 hose and wire harness use 2 white clamps which must orient with their paint mark up and you should also apply the black clamp to these components before inserting the body hole clip through the paint mark alignment. To finish the rebuild of this system the mechanic should install the air cleaner assembly before adding the air cleaner hose assembly followed by the V-bank cover sub-assembly then front fender apron seal front RH by installing 3 bolts with a screw and 5 clips and 3 screws with a T30 "TORX" socket for the front fender liner RH. Lastly connect the liner to the front bumper cover with a screw install the front fender splash shield sub-assembly RH and reconnect the cable to the negative battery terminal.
