  Q: How to remove the timing belt on Toyota 4Runner?

  A: The first step to replace the 2UZ-FE timing belt requires draining the engine coolant and separating the negative terminal from the battery. You should begin by taking off the 2 nuts from the throttle body cover sub-assembly before removing the air cleaner hose assembly together with the radiator support seal upper using the 11 clips. Start by unfastening each clip and the 2 hose clamps which enable separation of the 2 oil cooler hoses from the fan shroud followed by the removal of the 3 bolts needed to detach the fan shroud from the radiator before finally removing the 4 nuts to separate the fan with fluid coupling from the engine. Together remove the fan shroud and fan with fluid coupling from the vehicle along with the fan pulley. Open the vacuum hose to remove the vane pump assembly's nut along with its 2 bolts while hanging the hoses rather than detaching them. Remove the generator assembly followed by disconnecting the compressor connector before taking off the nut and 3 bolts and compressor stay and compressor while carefully hanging up the hoses. Uninstall the No. 2 idler pulley sub-assembly which requires removal of the pulley bolt and idler pulley and cover plate before disconnecting three hoses and removing bolt then nut and oil cooler pipe. Start by opening the 4 bolts which secure the No. 3 timing belt cover sub-assembly LH after disconnecting the cam position sensor connector. Proceed with removing the No. 2 timing chain or belt cover after removing its nut and 3 bolts. Subsequently remove the sub-assembly by dismantling the 2 bolts. Disconnect the V-ribbed belt tensioner assembly following bolt removal and disassembly of the two nuts and detach the fan bracket sub-assembly by unfastening the two nuts and two bolts. To remove the pulley bolt from the crankshaft damper sub-assembly use Special Service Tools: 09213-70011 and 09213-70020 followed by the crankshaft pulley removal with Special Service Tools: 09950-50013 and 09951-05010. Start the timing belt removal by uninstalling the four bolts from the No. 1 cover then proceed to take off the 1st crankshaft position sensor plate. Before dismantling the timing belt check for three installation marks distributed on the belt surface while the crankshaft turns. The No. 1 cylinder requires an initial positioning to approximately 50 degrees BTDC/compression. The engine technician sets crankshaft position at 50 degrees BTDC/compression while aligning both crankshaft timing pulley marks with oil pump body and verifies proper camshaft pulley and timing belt plate alignment. A single complete crankshaft turn must occur before rotating it counterclockwise halfway towards the 50 degrees position. Begin by alternatively loosening and finally removing the 2 bolts and chain tensioner unit with dust boot. Complete the removal process by operating Special Service Tool: 09960-10010 to relax the camshaft timing pulley (RH bank) tension versus the crankshaft timing pulley through counterclockwise rotation and separate the timing belt from the No. 1 timing belt idler to extract the timing belt.
