How to service and repair the Exhaust Pipe on Cadillac DeVille?

The exhaust crossover pipe can be serviced by removing the transaxle assembly and left and right side Exhaust Manifold bolts first. Replacement of the egr valve inlet pipe becomes necessary when disconnecting a crush seal at the water crossover point. Before installation start by removing the egr inlet pipe from the exhaust crossover and extracting the exhaust front pipe. The crossover pipe servicing requires a first step to remove the bolt attached to the crankcase followed by the nut linked to the ignition module ground wire to the Cylinder Head then the bolt holding the crossover pipe to the Cylinder Head before finally freeing the crossover pipe. Start the installation by applying the two flange seals to the crossover pipe before positioning it with the left-hand Exhaust Manifold joint remaining loose. Install the exhaust front pipe after resorting to hand tightening the support bolts (1,3). Install the Cylinder Head support bolt together with the crankcase support bolt until both reach a torque of 25 nm (18 ft. Lbs.). The installer must reinstall the ignition module ground wire nut which should be tightened to 17 nm (13 ft. Lbs.) torque setting on the Cylinder Head. Start by screwing the left hand Exhaust Manifold bolts to 25 nm (18 ft. Lbs.). Start the connection of egr inlet pipe-to-crossover pipe by hand to avoid cross-threading then use 60 nm tension (44 ft. Lbs. Torque value). Finally, reinstall the transaxle assembly.

How to replace the Front Exhaust Pipe on Cadillac DeVille?

The first step to replace the front Exhaust Manifold pipe includes removing the rear Exhaust Manifold pipe along with the transaxle assembly. The first step involves unbolting the two pieces connecting the left Exhaust Manifold to the front Exhaust Manifold pipe while a third bolt binds the front Exhaust Manifold pipe to the crankcase. Detach the nut holding the coil cassette ground wire to the Cylinder Head along with the bolt executed on the front Exhaust Manifold pipe to the Cylinder Head. The installation process begins with front Exhaust Manifold pipe nut detachment from the egr inlet pipe until the front Exhaust Manifold pipe and its seal can be removed from the left Exhaust Manifold. Replace the seal with a new one during the process. In addition remove the Exhaust Manifold flange retainer. You must install the retainer with a new front Exhaust Manifold pipe seal covering the left Exhaust Manifold before sliding in the front Exhaust Manifold pipe around it. Secure the front Exhaust Manifold pipe (1,3) to the engine with the bolts which require tightening to 25 nm (18 ft. Lbs.). First attach the bolt securing the coil cassette ground wire to the Cylinder Head until it reaches 17 nm (13 ft. Lbs.) and then tighten the 2 front Exhaust Manifold pipe bolts that secure it to the left Exhaust Manifold to 25 nm (18 ft. Lbs.). You should manually begin tightening the egr inlet pipe nut to the front Exhaust Manifold pipe since it prevents threading issues before completing the screwing to 60 nm (44 ft. Lbs.). Reinstall the rear Exhaust Manifold pipe and the transaxle assembly in the vehicle.
