• Q: How to remove the timing chain on 2008 Toyota Corolla?

  A: The necessary first step for removing the 1ZZ-FE timing chain begins by detaching the battery negative terminal followed by removing both front wheel RH and engine under cover RH. The next step requires removing cylinder head cover No. 2 by removing the 2 nuts and disconnecting 2 clips. The first step should include draining engine coolant followed by extracting both the fan and generator V belt. You must separate both the vane pump assembly and the generator assembly. The engine mounting insulator RH should be removed by taking out 2 bolts and the oil reservoir bracket No. 1 so you can jack the engine and then remove 4 bolts and 2 nuts. First remove the ignition coil connectors before taking off 2 nuts to disconnect the engine wire while unfastening 4 bolts for removing the ignition coils. The procedure involves removing the ventilation hoses from the cylinder head cover and unfastening 3 clamps from the engine wire followed by uninstalling 9 bolts and 2 seal washers and 2 nuts and 3 clamp brackets to remove this component. The first step to remove the V-ribbed belt tensioner assembly consists of bolt and nut removal while engine jacking may be needed according to installation needs. The engine mounting bracket RH requires removal through the process of dismantling 3 bolts leading to water pump assembly extraction. Use a wrench to detach the crankshaft position sensor through the removal of its 2 bolts. The procedure requires placing No.1 cylinder at TDC/compression while aligning the crankshaft pulley grooves with "0" timing marks and verifying camshaft timing gear alignment. The crankshaft pulley bolt can be removed using Special Service Tool: 09960-10010 09962-01000 09963-01000 before proceeding with the crankshaft pulley removal. First remove the two nuts securing assembly number one chain tensioner while preventing any crankshaft rotation that would occur without the chain tensioner. The removal of timing chain or belt cover sub-assembly will require removing 10 bolts and 2 nuts while using a "TORX" wrench socket (E8) for stud bolt removal and careful prying of the cover. A screwdriver should be used to remove the timing chain or belt cover oil seal. The first step involves removing crankshaft position sensor plate No.1 from the crankshaft parameter before extracting the chain tensioner slipper by disassembling the bolt. With two screwdrivers work to remove the chain sub-assembly but cover the engine with a shop rag while turning the crankshaft one-quarter rotation to maintain piston-valve separation.
