Caution is advised as the timing system is complex, and mistakes can lead to severe engine damage; only highly experienced individuals should attempt this procedure, and consulting an expert is recommended if there is any uncertainty. Begin by evacuating the air conditioning system at a certified service facility, disconnecting the negative battery terminal, draining the cooling system, and removing the upper radiator hose. Loosen the lug nuts on the right front wheel, raise the vehicle securely on jackstands, and remove the right front wheel along with the plastic splash shields. Proceed to remove the oil pan and coolant reservoir, then support the engine and remove the upper engine mounts and loosen the transaxle mount bolts. Remove the intake manifold and its support bracket, set the number one cylinder to TDC on the compression stroke, and take off the valve covers. Remove the drivebelt, crankshaft pulley, power steering pump, air conditioning compressor, alternator, drivebelt idler pulley, tensioner, and water pump pulley. Take off the timing chain cover, carefully laying out the bolts in order, and verify that the number one cylinder remains at TDC. Paint match marks on the chains where they align with the sprockets, compress the right chain tensioner, and remove the right upper chain guide, tensioner, and chain. Continue by removing the right chain guide, oil pump chain cover, oil pump chain, tensioner, guide, sprocket, and crankshaft gear. Repeat the removal process for the left timing chain components. Inspect all parts for wear and damage, checking the timing chain, sprockets, chain guides, and auto tensioners for any issues, replacing components as necessary. Clean the front of the engine, replace the crankshaft oil seal if needed, and align the camshafts with their TDC marks. Install the timing chain guide, chains over the crankshaft sprocket, tensioner arm, and tensioner, ensuring no slack exists. Pull the pins from both chain tensioners, install the oil pump chain guide and tensioner, then rotate the engine two complete turns clockwise to realign the timing marks, stopping if any resistance is felt. Clean the timing chain cover sealing surfaces, apply RTV silicone sealant where necessary, and install the cover, tightening all bolts to the specified torque values. Finally, reverse the removal process for the remainder of the installation, and after test driving to check for leaks, recharge the air conditioning system.
