Chevrolet Beretta Intake Manifold Parts Questions & Experts Answers
- Q: How do you remove the manifold in V6 engine?A: To remove the manifold, you should first release fuel system pressure and disconnect the negative battery cable. Next, get rid of the plenum, injectors and fuel rail, also the serpentine drive belt and drain cooling system. Remove alternator and loosen bracket and power steering pump if equipped. Disconnect coolant tubes and hoses, label and unplug any remaining electrical wires as well as fuel lines. After that remove the rocker arm covers then manifold mounting bolts being careful not to pry between the manifold and heads. Lastly, loosen the rocker arm nuts then rotate out of the way while removing Pushrods going through manifold gasket. During installation ensure that their mating surfaces are clean by using a gasket scraper to remove any old sealant or gasket material. Use lacquer thinner or acetone to clean surfaces and vacuum cleaner should be used in order to remove any debris from intake ports or lifter valley. Chase threads in bolt holes if necessary then apply a bead of ATV sealant or equivalent on front and rear ridges of engine block. The installation process involves installing intake manifold gasket, pushrods, rocker arms etc… Carefully lower the manifold into place and install mounting bolts/nuts finger tight; Tighten mounting bolts/nuts in three steps working from center out in a crisscross pattern; Finally reinstall remaining components, change oil filter refill cooling system & start engine check for leaks.
- Q: How do you remove the intake manifold in 2.3L four cylinder (Quad-4) engine?A: To take out the intake manifold, it is necessary to first reduce the fuel system pressure and remove the negative battery cable. Next, empty the cooling system then carry out removal of throttle body. Start by labeling vacuum and breather hoses, electrical wires etc before removing oil/air separator, oil fill cap and dipstick assembly. Unbolt / detach oil fill tube from engine block; remove intake manifold brace then loosen up manifold mounting nuts/bolts. In case of need use soft-face hammer to displace manifold away from Cylinder Head. For proper installation ensure that mating surfaces of cylinder head and manifold are clean and make use of gasket scraper to get rid of old sealant as well as gasket material. Clean mating surfaces with lacquer thinner or acetone. Chase threads in bolt holes with tap; blow out chips with compressed air; put gasket on cylinder head with all openings properly aligned; place intake manifold without tearing gasket; start nuts /bolts by hand then three step tighten them down finally reverse remaining removal steps, start engine up and check for leaks at intake manifold joints.
- Q: How to remove and install an intake manifold in 2.0L/2.2L four cylinder overhead valve engine?A: Relieve the fuel pressure, then disconnect the negative battery cable from the battery. Caution: 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. Remove the TBI cover/air cleaner assembly. Raise the front of the vehicle and support it securely on jackstands. Drain the coolant. Label and disconnect any wires and vacuum hoses that will interfere with manifold removal. Remove the throttle and TV cables and brackets. Remove the TBI assembly and fuel lines. Remove the power steering pump (if equipped) and tie it aside in an upright position. Remove the heater hose and coolant line retaining nut near the bottom of the intake manifold. Remove the mounting nuts from the intake manifold. Separate the intake manifold and gasket from the engine. Scrape all traces of gasket material off the intake manifold and head gasket mating surfaces. Installation is the reverse of removal. Make sure to use a new gasket. Tighten the nuts/bolts in the proper sequence. Add coolant, run the engine, and check for leaks and proper operation.
