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

  A: The installation of a timing belt on the 2UZ-FE engine requires the first step to involve checking No. 1 and No. 2 timing belt idlers for oil leaks and proper functionality before deciding on replacements. The water pump requires two inspections for coolant leakage and the bearing should move exactly as it should before replacing the components. The replacement of all pulleys including the crankshaft and oil pump along with the water pump and two idler units should occur without employing cleansers. Follow this procedure by placing the No. 1 cylinder at TDC/compression when the camshaft timing pulley marks match the crankshaft timing pulley marks. Position the timing belt over the crankshaft timing pulley followed by No. 2 idler, camshaft timing pulleys on both LH and RH banks and water pump pulley and No. 1 idler while making sure installation marks match their corresponding timing marks. Press the push rod at 981 to 9,807 N while aligning the holes before securing it with a 1.27 mm hexagon wrench on the belt tensioner. Proceed by releasing the press and installing the dust boot. The temporary belt tensioner installation requires two bolt tightening procedures at 26 Nm before you remove the hexagon wrench. Use the crankshaft pulley to check the valve timing while rotating it clockwise from TDC for two revolutions, reinstall the timing belt if any pulleys do not match their timing marks. The proper orientation of No. 1 crankshaft position sensor plate must be followed by securing the timing belt cover with four bolts torqued to 7.5 Nm. Use Special Service Tool: 09223-46011 to tap in the pulley set key into the crankshaft damper key groove before installing the damper bolt with Special Service Tool: 09213-70011 and Special Service Tool: 09213-70020 and torquing it to 245 Nm. The sub-assembly of fan bracket should be installed when idler pulleys retain two bolts along with two nuts prior to reaching torque values of 16 Nm for 12 mm head measurements and 32 Nm for 14 mm head measurements. After securing the V-ribbed belt tensioner assembly with its bolt and two nuts torqued to 16 Nm, continue by installing the No. 2 timing belt cover with two bolts torqued to 16 Nm. Install the No. 3 timing belt cover sub-assembly using four bolts which require torque of 7.5 Nm followed by installing the No. 2 timing chain or belt cover sub-assembly through one nut and three bolts tightened to 7.5 Nm. The oil cooler pipe needs one bolt and one nut installation where torque reaches 7.5 Nm before attaching the three hoses. Mount the single bolt of the No. 2 idler pulley sub-assembly at 39 Nm torque followed by compressor installation with stay, nut, and three bolts torqued at 47 Nm while the nut reaches 25 Nm torque. Mount the generator assembly and vane pump assembly with one nut alongside two bolts before torquing them to 43 Nm. Install the fan with fluid coupling by starting with engine pulley attachment to the fan followed by placing the fan-shroud combination into the engine compartment to tighten three bolts to 5.0 Nm and the fan coupling bolts with four nuts to 29 Nm. The final steps include fitting the fan and generator V belt before adding the radiator support seal upper, air cleaner hose assembly and throttle body cover sub-assembly with 7.5 Nm torques on its two nuts. Engine coolant must be added along with leak checks.

  Q: How to Service and Repair a Timing Belt on Toyota Camry?

  A: The service procedure starts with unfastening the generator and right-hand front wheel together with the right-hand front fender apron seal and PS pump drive belt through two bolts. Start the procedure by disconnecting the ground strap connector followed by removing the engine moving control rod after disassembly of 3 bolts and the No.2 right-hand engine mounting bracket with its associated 3 bolts. Start by disconnecting the 4 thick cords from the spark plugs and clamps on the cylinder head cover and then remove both the spark plugs and the No.2 timing belt cover after removing its 4 bolts and two engine wire clamps. Turn the crankshaft pulley to position the No.1 cylinder at TDC/compression where the timing mark "0" lines up with the No.1 timing belt cover while the camshaft timing pulley hole addresses the bearing cap timing mark. The camshaft timing pulley requires Special Service Tool: 09249-63010, 09960-10010 (09962-01000, 09963-01000) for removal of its bolt that enables loosening. Subsequently remove the crankshaft pulley using Special Service Tool: 09213-54015 (91651-00855), 09330-00021 (and bolt) together with proper alignment of matchmarks if reusing the timing belt. Proceed to eliminate the No.1 timing belt cover, timing belt guide, and timing belt while noting down the engine revolution direction for belt reuse. First remove the No.1 idler pulley alongside its tension spring and then extract the No.2 idler pulley from the system. For optimal results use Special Service Tool: 09950-50012 (09951-05010, 09952-05010, 09953-05010, 09953-05020, 09954-05020, 09954-05010) for the removal process of the crankshaft timing pulley. Use Special Service Tool: 09960-10010 (09962-01000, 09963-00500) to free the pulley nut of the oil pump. Look for any damage on the timing belt that is not bent and not twisted and not in contact with oil water or steam also check for idler pulley oil leakage and normal operation. Free-length measurement of tension spring (42.0 mm) combined with 32 - 37 N tension reading at 50.5 mm will indicate whether replacement is required. Position the oil pump pulley first and install the crankshaft timing pulley while ensuring no damage to the angle sensor. Put on the second idler pulley after setting the first idler pulley with the tension spring and verifying normal operation. Begin by installing the timing belt with proper point alignment along with maintaining cleanliness until you place the timing belt guide followed by the No.1 timing belt cover while inspecting the gasket for damages. After securing the crankshaft pulley to the proper torque standard the technician can install the camshaft timing pulley then sets the No.1 cylinder at TDC compression and connects the timing belt to the pulley during the tension check. The valve timing check involves rotating the crankshaft pulley clockwise when the No.1 idler pulley bolt is loosened to align its timing marks before tightening the bolt. Check the No.2 timing belt cover while inspecting gaskets for damage then install the spark plugs and high-tension cords. The installation sequence continues with the No.2 right-hand engine mounting bracket and then follows with engine moving control rod, ground strap connector, PS pump drive belt and right-hand front fender apron seal and right-hand front wheel and generator.

  Q: How to remove and install the timing belt on Toyota Tacoma?

  A: The first step to remove the timing belt requires removal of the engine under cover followed by draining engine coolant before disconnecting the upper radiator hose. Professionals should disconnect the PS pump by taking off two PS air hoses from both the air intake chamber and resonator while also unfastening the PS pressure tube frame clamp bolt and drive belt together with the PS pump bolt and nut. You must first disconnect the A/C compressor from the engine through removing its connector and drive belt and four bolts. The servicing engineer starts by opening the fan with fluid coupling and fan pulleys while removing the generator drive belt followed by the No.2 fan shroud and fan with fluid coupling and fan pulleys and finally the A/C compressor bracket using five bolts. Start by removing the oil dipstick guide then detach the No.2 timing belt cover through disconnecting four high-tension cord clamps and six bolts and disconnecting the camshaft position sensor connector. The PS pump adjusting strut needs removal while unscrewing its associated nut to access the fan bracket with its bolt and nut. The crankshaft pulley removal sequence starts with bolt loosening using Special Service Tool: 09213-54015 (90119-08216) 09330-00021 followed by removal of Special Service Tool: 09950-50011 (09951-05010, 09952-05010, 09953-05020, 09954-05031). Additional steps include using the tool to remove pulley bolt along with pulley. Two bolts must be removed from the starter wire bracket while four bolts need removal from the No.1 timing belt cover to proceed. Place the crankshaft pulley bolt temporarily to set the first cylinder at maximum compression point while checking for correct timing mark alignment between camshaft pulleys and the third timing belt cover. A careful examination should be done for the three installation marks and front mark on the timing belt. The addition of new marks will be necessary if any of those marks are missing during removal. Begin removing the timing belt tensioner by alternating the bolt looseness on two points before removing the timing belt. Use Special Service Tool: 09960-10010 (09962-01000, 09963-01000) to loosen the camshaft timing pulley bolt before you take off the bolt and knock pin along with the timing pulley for the RH side. Follow the same procedure for the LH camshaft timing pulley. Numerous steps follow for pulley removal where you need to first remove bolt from the No.2 idler pulley and secondly use 10 mm hexagon wrench to detach the pivot bolt and plate washer from the No.1 idler pulley. Start by removing the crankshaft timing pulley through the use of Special Service Tool: 09950-50011 (09951-05010, 09953-05020, 09954-05031) that includes a service bolt when needed. Check the timing belt for damages and bend and twist while verifying it does not touch oil, water or steam. Confirm it is installed correctly and look for signs of normal wear. The inspection of idler pulleys must include an evaluation for oil leakage and smooth operation while the timing belt tensioner needs evaluation for oil leakage along with proper push rod functionality. The crankshaft timing pulley should be installed with the set key in the groove followed by installation of the No.1 idler pulley at 35 Nm (350 kgf-cm, 26 ft. lbs.) and No.2 idler pulley at 40 Nm (400 kgf-cm, 30 ft. lbs.). The LH and RH camshaft timing pulleys need installation with the flange outside and Special Service Tool: 09960-10010 (09962-01000, 09963-01000) to tighten the pulley bolts to 110 Nm (1,100 kgf-cm, 81 ft. lbs.). Align the timing belt between its marks after cleaning before placing the belt at No.1 cylinder TDC. Press the push rod to adjust the timing belt tensioner and fasten it with a 1.27 mm hexagon wrench. Secure the tensioner using two bolts which should be tightened to 27 Nm (280 kgf-cm; 20 ft. lbs.). Adjust the valve timing by matching timing marks before installing the timing belt guide and No.1 timing belt cover and starter wire bracket while checking gasket conditions. Use Special Service Tool 09213-54015 (90119-08216), 09330-00021 to install the crankshaft pulley with a newly installed bolt that requires a torque of 295 Nm (3,000 kgf-cm, 217 ft. lbs.). The technician installs the fan bracket along with the A/C compressor bracket before fixing the fan with fluid coupling and fan pulleys as a temporary operation. Install the Number 2 fan shroud before adjusting generator drive belt tension while tightening the fan with coupling and pulleys to 5.4 Nm (54 kgf-cm, 48 inch lbs.). Then secure the A/C compressor to the engine using four bolts tightened to 25 Nm (250 kgf-cm, 18 ft. lbs.) and connect the PS pump to the engine with 43 Nm (440 kgf-cm, 31 ft. lbs. torque). After connecting the upper radiator hose you should add coolant to the engine then start it to search for leaks during the procedure followed by engine under cover installation and a road test to check abnormal noise or operation before rechecking the engine coolant level.
