2001 Toyota Tundra Timing Belt Parts Q&A

• Q: How to Properly Remove and Install a Timing Belt on 2001 Toyota Tundra?

  A: The first step for timing belt removal starts with removing engine under cover along with draining engine coolant and extracting the radiator assembly. Proceed by opening the throttle body cover and disconnecting the intake air connector assembly before moving on to remove the fans. Start by unscrewing 4 nuts holding the fluid coupling to the fan bracket followed by removing the drive belt and all 4 nuts as well as separating the fan and fluid coupling assembly. The PS pump requires removal of its 3 retaining bolts followed by appropriate suspension for safekeeping. Detach the drive belt idler pulley by unlatching its pulley bolt followed by its cover plate along with removing the idler pulley. To begin with the RH No.3 timing belt cover requires unboltage of its 3 bolts alongside its nut before moving onto the LH No.3 timing belt cover where the engine wire needs detachment from its two wire clamps followed by removal of 4 bolts and a nut and the disconnection of the camshaft position sensor wire and connector and finally disassembly of the cover including bolt and nut and oil cooler pipe. The procedure entails removing the No.2 timing belt cover through its two bolts followed by disconnecting the air conditioner compressor from engine operations and then removing the fan bracket through its two bolts and two nuts. After reuse of the timing belt confirm the existence of three installation indicator marks on the crankshaft pulley while turning it; create fresh marks if these marks are absent. Use Special Service Tool: 09213-70010 (90100-08076), 09330-00021 to transform the crankshaft pulley bolt while setting No.1 cylinder at TDC/compression by matching the crankshaft pulley groove with the timing mark "0" of the No.1 timing belt cover to maintain proper alignment of camshaft timing pulleys and timing belt rear plates. Begin by unscrewing the crankshaft pulley bolt while preventing crankshaft movement, follow by removing the timing belt tensioner using marks at new positions to keep on using the timing belt. Use Special Service Tool: 09960-10010 (with alternative numbers 09962-01000 and 09963-01000) to detach the timing belt from camshaft timing pulleys before removing them together with the same tool. Special Service Tool 09950-50012 (09951-05010, 09952-05010, 09953-05010, 09953-05020, 09954-05010) assists in the removal process which includes taking out the generator, drive belt tensioner, crankshaft pulley and requires avoiding crankshaft pulley rotation. Drop the No.1 timing belt cover along with the timing belt guide and timing belt before you put new marks for installation if using them again. Use a 10 mm hexagon wrench to detach the No.1 idler pulley and No.2 idler pulley after which you can remove the crankshaft timing pulley under specific instructions. Measure the timing belt for damages while ensuring it stays clear of oil and water and steam contamination. Also check the timing belt tensioner and idler pulleys for functioning properly without oil leakage. Begin installation by fitting the crankshaft timing pulley to the set key groove while using Special Service Tool: 09223-46011 for installation. Place adhesive on the pivot bolt of both the No.1 and No.2 idler pulleys before installing them so they move with ease. Place the temporary timing belt in position when the engine remains cool with a clean environment while correctly positioning the markup against the crankshaft timing pulley. Mount the timing belt cover spacer together with timing belt guide and No.1 timing belt cover correctly torqued. After installing the crankshaft pulley and drive belt tensioner and generator you have to check the crankshaft pulley position. Set the timing belt tensioner after connecting the timing belt to both camshaft timing pulleys which have been installed. Validate valve timing by rotating the crankshaft pulley and confirm the timing marks align before using Special Service Tool: 09213-54015 (90119-08216), 09330-00021 to tighten the crankshaft pulley bolt. Secure the fan bracket with A/C compressor where available, a synchronization of the No.2 timing belt cover followed by installation of RH and LH No.3 timing belt covers including all other required wiring connections. The last installation steps include drive belt idler pulley, PS pump, fan pulley, fan, fluid coupling, drive belt, then intake air connector assembly, throttle body cover, radiator assembly, engine coolant filling, initial engine start for leak check and final engine under cover installation.
