Q: How to remove and install a timing chain cover in 2.0L/2.2L four cylinder overhead valve engine?
A: Remove the Crankshaft Pulley (and hub, if equipped). Remove the Oil Pan. Remove the drivebelt tensioner and the timing cover-to-block bolts, then detach the cover. Use a scraper and degreaser to remove all old gasket material from the sealing surfaces of the timing cover, engine block, and oil pan. If necessary, carefully pry out the front oil seal from the cover with a large screwdriver. Do not distort the cover. Install the new seal with the spring side toward the inside of the cover. Drive the seal into place using a seal installation tool or a large socket and hammer. A block of wood will also work. Use a thin coat of ATV-type sealant to position a new gasket on the timing cover. Place the cover in position over the dowel pins on the block. Install the bolts that secure the cover to the block, then tighten all of them. Follow a criss-cross pattern to avoid distorting the cover. Install the oil pan. Complete the installation by reversing the removal procedure.
Q: How to remove and install the timing chain cover in V6 engine for a Chevrolet Beretta?
A: Disconnect the negative battery cable from the battery. On models equipped with the Delco Loc II audio system, make sure the lockout feature is turned off before performing any procedure that requires disconnecting the battery. Loosen the water pump pulley bolts, then remove the serpentine drivebelt. Remove the water pump pulley. Remove the vibration damper. Unbolt the drivebelt tensioner and idler, if equipped. Drain the coolant and engine oil. Remove the alternator and loosen the mounting bracket. Unbolt the power steering pump (if equipped) and tie it aside. Leave the hoses connected. Unbolt the flywheel/driveplate cover below the transaxle. Remove the starter. Remove the Oil Pan. Disconnect the coolant hoses from the fill pipe and water pump. Unbolt the spark plug wire shield at the water pump. Disconnect the canister purge hose and tie it aside. Remove the Timing Cover-to-engine block bolts. Note that some of the bolts require T-40 or T-50 Torx bits for removal. Separate the cover from the engine. If it is stuck, tap it with a soft-face hammer, but do not try to pry it off. Use a gasket scraper to remove all traces of old gasket material and sealant from the cover and engine block. The cover is made of aluminum, so be careful not to nick or gouge it. Clean the gasket sealing surfaces with lacquer thinner or acetone. Apply a thin layer of sealant to the lower corners on both sides of the new gasket, then position the gasket on the engine block (the dowel pins should keep it in place). Attach the cover to the engine and install the bolts. Apply sealant to the bottom of the gasket. Follow a criss-cross pattern when tightening the fasteners and work up. The remainder of the installation is the reverse of removal. Add oil and coolant, start the engine, and check for leaks.
