Cadillac Exhaust Manifold Parts Questions & Experts Answers
- Q: How to replace the right exhaust manifold (LA3, LY9) on Cadillac CTS?A: The replacement of the right Exhaust Manifold (LA3, LY9) requires starting with drive belt tensioner removal. Two cable harness clips attaching engine wiring harness to ecm bracket should be removed before setting them aside. Rivet the after boil coolant pump from the ecm bracket with its two bolts before setting them aside. The heated Oxygen Sensor pigtail needs disconnecting from the wiring harness connector. Detach all retaining nuts from both the top section and front section of the right Exhaust Manifold. Start by removing the Starter and heated Oxygen Sensor when necessary followed by removing all remaining right Exhaust Manifold retaining nuts. Take off the right Exhaust Manifold along with its gasket from the engine space without keeping the gasket for reuse. Thoroughly examine and clean the right Exhaust Manifold before assembling it to the engine. New Exhaust Manifold gaskets go over the cylinder head studs before installing the right Exhaust Manifold on its corresponding right cylinder head. The three lower nuts of the right Exhaust Manifold require torque to 20 nm (15 ft. Lbs.). First install the heated Oxygen Sensor before reconnecting the Starter if it was taken off. Fasten all remaining right Exhaust Manifold nuts while applying 20 nm (15 ft. Lbs.) resistance for these attachments. Position the heated Oxygen Sensor pigtail to its wiring harness connector and fasten the 2 bolts which secure the after boil coolant pump to the ecm bracket before tightening them to 10 nm (89 inch lbs.). After securing the drive belt tensioner one must reconnect the 2 cable harness clips which secure the engine wiring harness to the ecm bracket.
- Q: How to replace the right side exhaust manifold on Cadillac Escalade?A: The first step to replace the right side Exhaust Manifold requires draining the cooling system because rear air conditioning is present. In the first step you should remove the ignition coils alongside spark plugs and oil level indicator tube together with heated Oxygen Sensor (HO2S). First lower the vehicle while removing Catalytic Converter to Exhaust Manifold nuts from both parts (1500 series shown, 2500 series similar). Rear a/c is present so operators should first move the radiator surge tank outlet hose clamp at the Water Pump and extract the hose from its position at the Water Pump before repositioning it out of the way. The installation starts by loosening the heater inlet hose clamp at the Water Pump and removing both the clamp and heater inlet hose for subsequent position aside. The next step involves removing Exhaust Manifold bolts and the Exhaust Manifold with the disposal of an Exhaust Manifold Gasket while extracting the exhaust seal present on the Exhaust Manifold. Insert the exhaust seal onto the Exhaust Manifold before treating its Exhaust Manifold bolts with a 5 mm (0.2 in) wide threadlocker band using gm p/n 12345493 (Canadian P/N 10953488). First tighten two center bolts of the Exhaust Manifold to 15 n.m (11 lb ft) before progressing to side bolts in an alternating pattern until reaching 20 n.m (15 lb ft). Install the Exhaust Manifold to the Cylinder Head followed by Exhaust Manifold bolts after which press the exhaust seal onto the Exhaust Manifold using threadlock gm p/n 12345493 (Canadian P/N 10953488). A flat punch will be used to bend the gasket tab at the rear circular edge of the gasket around the Cylinder Head. The installation of the heater inlet hose requires positioning it at the Water Pump followed by clamping it down with the heater inlet hose clamp when rear a/c is used. Attach the radiator surge tank outlet hose to the Water Pump through its clamp while keeping the outlet hose in position. Uphold the vehicle before installing the Catalytic Converter to its Exhaust Manifold nuts while tightening them to 50 n.m (37 lb ft). The technician must reinstall the oil level indicator tube followed by installation of spark plugs and ignition coils after lowering the vehicle. Finally, fill the cooling system.
- Q: How to replace the left exhaust manifold on Cadillac XLR?A: The powertrain must be removed before starting the left Exhaust Manifold replacement. The pipe attachment to the bell housing relies on a manifold and Catalytic Converter assembly bolt for holding power. Users should first eliminate the connector position assurance (CPA) lock on the oxygen sensors before removing the Oxygen Sensor electrical connectors (1, 2). One must exercise precaution while dealing with Oxygen Sensor procedures. Start by removing the oxygen sensors from their position after which remove the left Exhaust Manifold heat shield bolts alongside the heat shield itself. First remove the bolts and nuts that secure the Exhaust Manifold before taking out the manifold itself along with the left Exhaust Manifold Gasket which should be disposed. The installation requires clean threads inside Exhaust Manifold holes of the Cylinder Head which must be free from debris and threadlocking substances. Embed a 5 mm (0.2 in) width threadlock gm p/n 12345493 (Canadian P/N 10953489) adhesive material along the threads of the Exhaust Manifold bolts and studs. Position the Exhaust Manifold along with its new gasket in its correct position. Extreme care must be taken because of fastener safety concerns. Start by installing the center Exhaust Manifold bolts and nuts first before moving toward the outer hardware while alternating the bolt direction from one side to the other. Tighten all hardware to 25 nm (18 lb ft). Position the Exhaust Manifold Catalytic Converter hanger bolt to the bell housing before tightening it to 50 nm (37 lb ft). Install the left Exhaust Manifold heat shield followed by its bolts while tightening each bolt to 10 nm (89 lb in). The threads of the oxygen sensors require application of anti-seize compound gm p/n 12377953 or equivalent before installation. When mounting sensors apply 42 nm (30 lb ft) force to the threads. Connect the Oxygen Sensor electrical wires while using cpa locks for installation. Finally, reinstall the powertrain.
