The timing system is not simple and any error lead to severe damages of the engine; thus, this procedure should be accomplished only by experienced personnel and if there is any doubt, it is recommended to consult an expert. The initial steps involved include loose the negative terminal and then removing the engine cover as well as the drivebelt and the alternator the pulley on the power steering has to be unbolted but the hoses don't have to be detached. Second, unlock and then unbolt the tensioner, idler pulley and the air conditioning compressor and set it aside; then you can take off the intake manifold. Tighten the nut for the right front wheel securely and then remove it while the car is still running on jackstands by lifting the front of the vehicle and applying the parking brake /turning off the engine/, and block the rear wheels. If necessary, drain the engine oil and coolant, and remove, the lower oil pan, radiator, and coolant reservoir if necessary. Place support under the engine below, take off the upper engine mount bracket, the two valve covers and posed the number one cylinder to compression on the TDC. Take off the crankshaft pulley and, on this model and some others produced before the year 2000, the automatic transmission water pump pulley and the water pump. Remove the timing chain cover including the bolts and note their sequence, making sure that the number one cylinder is still at TDC, and mark the sprockets for reuse. The next steps are to compress the rear-bank chain tensioner and retain it before truncating by removing the rear-bank upper chain guide, tensioner, and chain as well as the oil pump chain cover and other components of the front bank timing chain. Every single part attached to the timing chain needs to be inspected and examined such as sprockets, chain guides and automatic tensioners and the corresponding parts that must be changed are replaced. Wash the surface of the front of the engine, make sure that the key of the crankshaft and camshafts point to the TDC and fix the timing chain, and guide and the chains stay over the crankshaft sprocket and there should be no loose movements. Next, the tensioner arm and the tensioner need to be installed, and after that, the pins in both the chain tensioners needs to be removed. Turn the engine clockwise to move the marks on all the sprockets into a straight line and ensure the procedure is done twice; there should be no resistance when rotating the engine. Next, degrease all the timing chain cover sealing surfaces and apply a new RTV silicone sealant if needed and reinstall the timing chain cover bolts to the marked torque and briskly restore the car in an order opposite to the disassembling order.
