2000 Toyota MR2 Spyder Parts Questions & Experts Answers

• Q: How to service and repair the timing chain on 2000 Toyota MR2 Spyder?

  A: To service and repair the timing chain, begin by draining the engine coolant and removing the rear suspension upper brace, engine under covers, drive belt, generator, drive belt idler (removing 2 bolts and 2 nuts), right-hand engine mounting insulator (using a jack with a wooden or rubber block for support, then removing 3 bolts and 3 nuts), ignition coils, and cylinder head cover (disconnecting 2 PCV hoses, noise filter, heated oxygen sensor connector, and removing 9 bolts, 2 nuts, and 2 seal washers). Set the No. 1 cylinder at TDC/Compression by positioning the crankshaft pulley at timing mark 0 and verifying that camshaft timing sprocket and VVT timing sprocket point marks are both aligned. After that, remove the bolt and disconnect the two connectors from the oil dipstick guide. Special Service Tools 09213-70011 and 09330-00021 help with crankshaft pulley removal before proceeding to take off the drive belt tensioner and right-hand engine mounting bracket and chain tensioner and water pump and crankshaft position sensor then timing chain cover through the removal of 11 bolts and a nut while being careful to prevent damage. The service technician needs to remove the crank angle sensor plate and proceed with removing the chain tensioner slipper and timing chain and crankshaft timing sprocket and VVT timing sprocket while using a wrench to protect the camshaft. The maintenance process includes measuring chain tensioner slipper and vibration damper wear (both should not exceed 1.0 mm) as well as checking for smooth movement of the chain tensioner plunger. The inspection of both sprockets and the timing chain must confirm an elongation of no more than 122.6 mm while the drive belt idler should exhibit smooth rotation. Install the crankshaft front oil seal through Special Service Tool: 09309-37010 while the timing chain cover remains separate from the installation of Special Service Tool: 09308-10010. Follow the order of Special Service Tools: 09950-60010, 09950-70010 to install the drive belt idler bearing before reinstalling the pulley. Install these component parts by first positioning the camshaft timing sprocket alongside the VVT timing sprocket and setting the No. 1 piston cylinder at TDC/compression position before adding the chain vibration damper and timing chain and crankshaft timing sprocket while maintaining correct timing mark alignment. Use new O-rings in the water pump installation together with timing chain cover, crank angle sensor plate, and chain tensioner slipper while placing seal packing as directed (Part No. 08826-00100 and 08826-00080). You should mount the right-hand engine bracket with seal packing threaded into place followed by the drive belt tensioner alongside the crankshaft position sensor and crankshaft pulley that requires Special Service Tools: 09213-70011, 09330-00021 to achieve proper chain tension. Check valve timing requires the crankshaft pulley groove to align with timing mark 0 and confirm point marks match between camshaft timing sprocket and VVT timing sprocket. To complete the engine installation you need to place the oil dipstick and guide under the cylinder head cover with its new gasket and seal packing (Part No. 08826-00080) above the right-hand engine mounting insulator and ignition coils with the No. 2 cylinder head cover and drive belt idler and generator and drive belt and engine under covers and suspension upper brace and ending with filling engine coolant while starting the engine to detect coolant leaks.
