Toyota 4Runner Parts Questions & Answers

• Radiator Assembly
  16400-50300
  Q: How to install the radiator assembly and its components on Toyota 4Runner?

  A: When installing the radiator component use 4 bolts to fasten the radiator support at the radiator service holes while reaching 18 Nm (184 kgf-cm, 13 ft-lbf) torques. Now attach the fan shroud tabs which fit into their respective openings by using two bolts tightened to 5.0 Nm (51 kgf-cm, 44 in-lbf). The radiator reserve tank assembly installation requires 3 bolts which should be secured to 5.0 Nm (51 kgf-cm, 44 in-lbf) torque before connecting the reserve tank hose to the radiator. The last step includes adding engine coolant before conducting a leak inspection.
• Timing Chain

  Q: How to install the timing chain on Toyota 4Runner?

  A: The procedure to install the 1GR-FE timing chain requires starting with the chain tensioner slipper installation followed by the No. 1 chain tensioner assembly including pushing the plunger while doing clockwise and counterclockwise rotations with a 3.5 mm (0.138 in.) bar until fixed before torquing the 2 bolts at 10 Nm (102 kgf-cm, 7 ft-lbf). Follow this by positioning the No. 1 cylinder at TDC/compression while your alignment task focuses on matching the timing marks of camshaft timing gears and bearing caps. At this point you can install the crankshaft pulley set bolt before using the crankshaft to make the set key match the timing line. Before lifting the chain into place you should position the yellow mark link adjacent to the crankshaft timing gear and the orange mark links should be applied to the camshaft timing gears. Place the No. 2 chain vibration dampers before you apply engine oil to the No. 1 idle gear shaft and fasten both components together through their knock pin position. Use the 10 mm hexagon wrench to fasten the No. 2 idle gear shaft to 60 Nm (612 kgf-cm, 44 ft-lbf) before taking out the bar from the chain tensioner. Embed the timing gear case oil seal, timing chain or belt cover sub-assembly, VVT sensor and camshaft timing oil control valve assembly with both 10 Nm (102 kgf-cm, 7 ft-lbf) bolts. Proceed to install the cylinder head cover sub-assemblies, ignition coil assembly at 10 Nm (102 kgf-cm, 7 ft-lbf), intake air surge tank, and oil pan sub-assembly, ensuring to remove old packing and apply a new O-ring to the oil pump, followed by a continuous bead of seal packing (3 to 4 mm (0.12 to 0.16 in.)) before tightening the oil pan bolts and nuts uniformly: bolt A at 21 Nm (214 kgf-cm, 15 ft-lbf), bolt B at 21 Nm (214 kgf-cm, 15 ft-lbf), bolt C at 10 Nm (102 kgf-cm, 7 ft-lbf), and nut at 21 Nm (214 kgf-cm, 15 ft-lbf). Install the 4 housing bolts at 37 Nm (377 kgf-cm, 27 ft-lbf) and the flywheel housing under the cover. After installing the new gasket and 2 nuts at 9.0 Nm (92 kgf-cm, 80 in-lbf) onto the oil strainer sub-assembly proceed with installing the No. 2 oil pan sub-assembly by applying seal packing then tightening the bolts and nuts uniformly at 10 Nm (102 kgf-cm, 7 ft-lbf). Apply Special Service Tools 09213-54015 91651-60855 and 09330-00021 to install the crankshaft pulley before mounting the No. 1 idler pulley sub-assembly at 54 Nm (551 kgf-cm, 40 ft-lbf). When installing the No. 2 idler pulley sub-assembly obey specific guidelines that depend on whether the idler pulley cover plate exists and perform needed replacements. Place the V-ribbed belt tensioner assembly then tightening bolt 1 and 2 to 36 Nm (367 kgf-cm, 27 ft-lbf) while following by additional bolt installation at the same torque value. After attaching the vane pump assembly with 2 bolts at 43 Nm (438 kgf-cm, 32 ft-lbf) you should connect the P/S oil pressure switch connector before installing the water inlet. The oil level gauge guide needs installation following application of a new O-ring with a 9.0 Nm (92 kgf-cm, 80 in-lbf) torque setting, then install the oil level gauge, air cleaner assembly and connect the No. 2 ventilation hose. Fitting the fluid coupling assembly together with the fan and generator V belt requires a complete torque tightening of the fluid coupling assembly. The service procedure includes first installing the radiator support seal upper before placing the battery and differential carrier assembly front and power steering link assembly. Along with oil and coolant addition follow a leak check then secure the V-bank cover using 2 nuts at 7.5 Nm (76 kgf-cm, 66 in-lbf) before inspecting the ignition timing.
• Alternator

  Q: How to service and repair the alternator on Toyota 4Runner?

  A: Start the alternator service procedure with rear end cover removal by detaching both the nut and terminal insulator and afterward removing the 3 nuts together with the end cover. Unscrew the 2 screws enabling you to remove the brush holder followed by its cover removal. The voltage regulator requires removal of its three screws. The rectifier holder requires detachment when executing this step by first removing its 4 screws as well as the 4 rubber insulators. Special Service Tool 09820-63010 should be employed for pulley maintenance through engagement with a torque wrench for clockwise tightening to 39 Nm (400 kgf.cm, 29 ft.lbf) in order to secure the tool onto the rotor shaft. The adapter should be placed in a vise followed by generator installation and finally a counterclockwise turn of the pulley nut while ensuring the rotor shaft stays undamaged with a half turn maximum rotation. Tear the generator from the adapter after removing both the socket tool as well as the pulley holding tool before uninstalling the pulley nut followed by the pulley. The rectifier end frame comes off first by turning loose its 4 nuts and utilizing Special Service Tool 09286-46011 before extracting the generator washer with snap ring pliers. The rectifier end frame should be placed onto the pulley before installation of the drive end frame rotor and proper orientation of the generator washer for assembly. Use a 29 mm socket wrench along with a press to gently tighten the rectifier end frame while securing it with 4 nuts at a torque measure of 4.5 N.m (45 kgf.cm, 39 in.lbf) torque. First secure the pulley shaft with your hand before tightening the nut then secure the pulley holding tool with a torque wrench to reach a torque of 39 Nm (400 kgf.cm, 29 ft.lbf) in clockwise direction. The procedure begins by securing the adapter in a vise while inserting the generator before tightening the pulley nut to 110.5 N.m (1,128 kgf.cm, 81 ft.lbf). The generator needs to be later removed from both the adapter and the socket and pulley holding tool. Place 4 rubber insulators onto the lead wires before installing them into the rectifier with 4 screws fastened at 2.0 N.m (20 kgf.cm, 18 in.lbf) torque. Strengthen the installation of the brush holder and voltage regulator by placing the brush holder cover onto the brush holder before you install both parts positionally on the rear end frame with the brush holder cover must stay aligned during setup and drive five mounting screws until you create a 1 mm (0.04 in.) gap between the brush holder cover and connector. Secure the rear end cover with 3 nuts that need to be torque to 4.5 N.m (45 kgf.cm, 39 in.lbf) then attach the terminal insulator with a nut at 4.1 N.m (42 kgf.cm, 36 in.lbf) to achieve smooth rotor rotation.
• Valve Sub-Assembly, Tire
  42607-33022
  Q: How should the TPMS Sensor and transmitter be disposed of, particularly regarding the lithium battery on Toyota 4Runner?

  A: It is necessary to remove the lithium battery from the tire pressure warning valve and transmitter before disposal. Proper disposal of the battery remains essential. A screwdriver enables removal of the back cover to reveal both the battery and base board that remains covered by silicone resin. The battery removal process requires the user to disconnect the two electrical terminals attaching the battery to the base board.
