OEM 2003 Toyota Land Cruiser Timing Belt

2003 Toyota Land Cruiser Parts Questions & Experts Answers

• Q: How to remove and reinstall the timing belt on 2003 Toyota Land Cruiser?

  A: You must begin belt timing removal by taking out the oil pan protector along with engine under cover followed by draining the engine coolant and pulling off the battery clamp cover and V-bank cover after detaching the fuel return hose and unscrewing the 2 bolts and 2 cap nuts. The first step begins with the air cleaner and intake air connector assembly followed by driving belt removal before handling the fan and fluid coupling and fan pulley by loosening their four installation nuts on the fluid coupling. Start the procedure by unwiring the radiator assembly and drive belt idler pulley through pulley bolt removal and disconnection of cover plate and idler pulley. Remove the RH No.3 timing belt cover by taking off three bolts along with a nut and disconnect the engine wire and camshaft position sensor wire from the LH No.3 timing belt cover before removing four bolts and a nut and extracting the cover and oil cooler pipe. Start the replacement process by removing the No.2 timing belt cover through bolt unfastening followed by A/C compressor engine detachment and removal of the fan bracket after unthreading its 2 bolts and 2 nuts. Assess the timing belt for its three installation indicators because removal needs marking of the belt if all marks are absent. Use Special Service Tool: 09213-70011 (90100-70020), 09330-00021 to loosen the crankshaft pulley bolt while setting the No.1 cylinder to TDC/compression by aligning the crankshaft pulley groove with the timing mark "0" during which you must verify the camshaft timing pulleys line up correctly. To begin the procedure remove the timing belt tensioner while marking the belt if you plan to reuse it. Then use Special Service Tool: 09960-10010 (09962-01000, 09963-01000) to disconnect the timing belt from both camshaft timing pulleys. Special Service Tool: 09950-50013 (09951-05010, 09952-05010, 09953-05010, 09953-05020, 09950-05011, 09954-05021) should be used to remove the generator and crankshaft pulley after the drive belt tensioner and camshaft timing pulleys following the removal of the same tool. If keeping the timing belt for use mark it first and then replace the No.1 timing belt cover together with the timing belt guide and the timing belt. The 10 mm hexagon wrench is required to remove the No.1 idler pulley and No.2 idler pulley from the engine while also taking out the crankshaft timing pulley without rotating it. Verification must occur of timing belt quality as well as idler pulley oil leakage performance and regular operation while ensuring the timing belt tensioner displays proper push rod motion and no oil leakage. Use the set key to correctly position the crankshaft timing pulley while installing No.1 and No.2 idler pulleys using adhesive before torquing them at 34.5 Nm (350 kgf-cm, 25 ft. lbs.). Install the timing belt on its temporary location when the engine has cooled down and clean all surfaces so that the installation mark lines up correctly with the crankshaft timing pulley. The spacer guide should be installed before using the 4 bolts to mount the No.1 timing belt cover. Install and torque the drive belt tensioner to 16 Nm (160 kgf-cm, 12 ft. lbs.) by using Special Service Tool: 09223-06011. Before moving forward with the installation proceed with checking the crankshaft pulley position while installing both RH and LH camshaft timing pulleys and connecting the timing belt to all three pulleys properly. Press the push rod on the timing belt tensioner while using a hexagon wrench to fasten it and then bolt down the tensioner with 26 Nm (270 kgf-cm, 19 ft. lbs.) torque. View the timing marks on the crankshaft pulley while turning it and replace the timing belt if the marks are not correctly aligned. Use Special Service Tool: 09213-70011 (90100-70020), 09330-00021 to tighten the crankshaft pulley bolt at 245 Nm (2,500 kgf-cm, 181 ft. lbs.) before mounting the fan bracket with the A/C compressor alongside No.2 timing belt cover and both RH and LH No.3 timing belt covers and end with the drive belt idler pulley installation following the proper torque limitations. The procedure ends with radiator assembly installation followed by fan components, air cleaner, V-bank cover, correct engine coolant filling, engine start-up to inspect for leakage, verification of coolant level and conclusion with battery clamp cover, engine under cover and oil pan protector.
