Q: How to service and repair the exhaust crossover exhaust pipe on Cadillac Eldorado?
A: Service and repair of the exhaust crossover pipe starts by eliminating the transaxle assembly from the vehicle. The first step requires removal of the two bolts located on the left side Exhaust Manifold combined with the exhaust front pipe. Service the crossover pipe by removing first the bolt that connects it to both the crankcase and the Cylinder Head followed by taking out the egr supply tube and pipe. Before crosspipe installation start by placing the two flange seals onto the crossover pipe while maintaining loose connection of the lh Exhaust Manifold joint. Secure the front Exhaust Pipe using hand torque on support bolts (1,3). Refer to manual for torque values to tighten Cylinder Head support bolt and crankcase support bolt . After installing the egr supply pipe you must fasten its nut to 60 nm (44 ft. Lbs.). The installation requires final tightening of left hand Exhaust Manifold bolts to 30 nm (22 ft. Lbs.) before finally reinstalling the transaxle assembly.
Q: How to replace the exhaust pipe extension on Cadillac SRX?
A: Attaining replacement of the exhaust Tail Pipe extension begins by supporting and elevating the vehicle. The exhaust system needs removal from both the rear suspension hanger rods and Tail Pipe hanger rods before the operation. First mark the exhaust tip position on the Exhaust Pipe before removing the weld from the exhaust tip top and bottom sections to detach the tip. Finish cleaning the welds still present on the Exhaust Pipe. Attach the new exhaust tip to the Exhaust Pipe while keeping it directly on the mark established during disassembly procedure. Reinstall the exhaust system to its positions on the rear suspension hanger rods and the Tail Pipe hanger rods while verifying that the exhaust tip remains well aligned with the vehicle body. After tacking the exhaust tip to the vehicle remove the exhaust system by taking it away from its mounting positions on both the rear suspension hanger rods and Tail Pipe hanger rods. Fix the new exhaust tip to the Exhaust Pipe at the same points as the first tip before reinstalling the exhaust system to the rear suspension hanger rods and the Tail Pipe hanger rods.
Q: How to replace the center exhaust pipe on Cadillac XLR?
A: The proper method to install adjustable jack stands under the front and rear of the intermediate pipe requires securely raising and supporting the vehicle first. Unfasten the two exhaust muffler band clamps (2, 5) to separate both left and right tailpipe/muffler assemblies from their connection to the intermediate pipe. Remove the lower Exhaust Pipe hanger bolts combined with the exhaust manifold nuts after which you can drop the jack stands to retrieve the intermediate pipe. When reinstalling the original intermediate pipe users must first mark the existing clamps locations before grinding off old ones and putting on new ones at those positions. After placing the intermediate pipe back on the jack stands you should raise them to achieve correct positioning of the pipe. Tighten all exhaust clamps and bolts only until they become tight enough for alignment but keep the adjustable jackstands in place. Proceed with tightening the Exhaust Pipe hanger lower bolts at a torque of 50 nm (37 lb ft) while the exhaust manifold nuts require 20 nm (15 lb ft) and the exhaust muffler clamps (2, 5) bolts need to be tightened to 44 nm (32 lb ft) after lowering the vehicle.
