2001 Cadillac Catera Exhaust Resonator Parts and Q&A

• Q: How to replace the exhaust resonator on 2001 Cadillac Catera?

  A: Start by elevating the automobile and keeping it in position to access the Exhaust Resonator. First, detach the Muffler to resonator clamp nuts (1, 2) and the right exhaust Muffler pipe flange bolts . The right exhaust Muffler pipe must be detached from its support rods by removing hanger insulator retainers from both rods before rotating the Muffler away from the resonator. After removing the hanger insulator retainers from the resonator support rods you should take off the retainers and remove the hanger insulators on the resonator. The left Muffler resonator should be rotated before detaching it. Start by placing the resonator onto the left Muffler and afterward put the hanger insulators onto the resonator. Secure the resonator hanger insulator retainers on the support rods and use them to mount the right exhaust Muffler to the resonator. The installation of exhaust Muffler pipe insulator hangers requires attachment to support rods before attaching the right exhaust Muffler followed by insulator hanger retainers to support rods. The installation requires flange bolt tightening for the exhaust Muffler pipe to 40 nm torque (30 ft. Lbs. Values). Screw in the Muffler to resonator clamp nuts (1, 2) before tightening them to 25 nm (18 ft. Lbs.). You must inspect exhaust system clearances as well as lowering the vehicle to search for exhaust system leaks.
