Q: How to replace the Exhaust Pipe on Chevrolet Camaro?
A: The first step to change the exhaust crossover pipe is to securely support your vehicle through lifting. Disconnect the Catalytic Converter hanger bolts and separate the hanger from its position. Turn the exhaust manifold pipe nuts to loose position on left and right sides before taking out the nuts at both sides that secure the Catalytic Converter. The crossover pipe needs users to slide forward till it disconnects from its left and right Catalytic Converter studs and can be extracted from the exhaust Muffler. The crossover pipe needs to be inserted into the exhaust Muffler where it should sit over left and right Catalytic Converter studs before realigning everything by sliding forward. Secure the right-side Catalytic Converter nuts at 25 nm (18 ft. Lbs.), then proceed to the left side and tighten them to 25 nm (18 ft. Lbs.). The exhaust manifold pipe nuts on the right and left sides should be fastened with 35 nm (26 ft. Lbs.) torque before moving onto the left side torque application at the same value. Lower the vehicle afterward while tightening the Catalytic Converter hanger bolts and its components to 41 nm (30 ft. Lbs.).
Q: How to replace the crossover exhaust pipe on LZE/LZ4/LGD engines on Chevrolet Impala?
A: The first step to replace the exhaust crossover pipe on lze/lz4/lgd engines requires removal of the air cleaner outlet duct. Begin the replacement by removing the electrical bolts connecting the exhaust crossover pipe heat shield followed by removing this protective shield. Arella out the exhaust crossover pipe nuts then detach the pipe before cleaning off the seals from the crossover pipe area. Installation of the exhaust crossover pipe begins with positioning the exhaust crossover pipe seals onto the exhaust manifolds followed by installing the exhaust crossover pipe. Attention should focus on secure fastening operations since nuts require a torque setting of 20 nm (15 lb ft). Replace the exhaust crossover pipe heat shield by installing bolts which should be secured at 10 nm torque limit (89 lb in). After finishing with this task return the air cleaner intake duct into its original position.
Q: How to replace the Exhaust Pipe on Chevrolet Malibu?
A: Vehicle elevation and subsequent support constitutes the starting point to change an Exhaust Manifold pipe. The heated Oxygen Sensor (HO2S) electrical connector must be disconnected first after removing the connector position assurance (CPA) retainer. Use the j 39194 Oxygen Sensor wrench (J 39194) to detach the ho2s subsequent to removing the Exhaust Manifold pipe to Muffler nuts and Exhaust Manifold/catalytic converter to Exhaust Manifold pipe nuts. The first Muffler hanger insulator requires removal before using gentle force on the Exhaust Manifold pipe studs to pull the Muffler apart from its position before getting rid of the Exhaust Manifold pipe. Installation begins with mounting the Exhaust Manifold pipe to the Exhaust Manifold/catalytic converter followed by using slight force to mount Exhaust Manifold pipe studs to the Muffler then reinstalling the first Muffler hanger insulator. Follow this procedure for installation: 1) secure the Exhaust Manifold/catalytic converter to its Exhaust Manifold pipe nuts at 35 n.m torque 2) apply torque of 30 n.m when securing the Exhaust Manifold pipe to Muffler nuts. Install the previous ho2s but first apply anti-seize compound gm p/n 12377953 or an equivalent product to its threads. Place the j 39194 (J 39194) tool to install the ho2s while torquing it to 42 n.m (30 lb ft). Ultimately connect the ho2s electrical connector then install the cpa retainer while lowering the vehicle below the floor.
