You will be very lucky to extract the studs whilst in the vehicle. Drop the front pipe. Sounds harder, but, in reality, much easier.

I need to remove the exhaust manifold on the right side of a 94 4.9l engine in a cadillac deville. It has a broken bolt in the exhaust. What is involved in removing the manifold?


I suggest you use all new exhaust manifold hardware and torque new bolts to 20 Ft Lbs.
4.5L and 4.9L Engines
RIGHT
Disconnect the negative battery cable. Remove the air cleaner. Remove the exhaust crossover pipe. Disconnect the oxygen and coolant temperature sensors. Remove the catalytic converter-to-AIR pipe clip bolt. Remove the upper manifold-to-cylinder head bolts. Raise and safely support the vehicle. Disconnect the converter air pipe bracket from the stud and remove the converter-to-manifold exhaust pipe. Support the engine cradle with screw jacks and remove the rear cradle bolts. Loosen the front cradle bolts and slightly lower the Engine cradle. Remove the remaining exhaust manifold-to-cylinder head bolts, the AIR pipe, and the manifold. Clean the gasket mounting surfaces.
To install:
Install the exhaust manifold and replace the AIR pipe. Tighten the manifold mounting bolts to 16-18 ft. lbs. (21-24 Nm). Install the manifold-to-converter exhaust pipe and replace the converter air pipe bracket to the stud. Raise the Engine cradle and install the rear cradle bolts. Tighten to 75 ft. lbs. (102 Nm). Lower the vehicle. Replace the upper manifold-to-cylinder head bolts. Replace the converter air pipe to AIR pipe clip bolt. Connect the coolant temperature and oxygen sensor connectors. Replace the exhaust crossover pipe. Replace the air cleaner and connect the negative battery cable. Start the Engine and check for leaks.

How to replace starter


Disconnect battery. Jack up vehicle on the drivers side and support. remove cables from starter. Remover the 2 bolts from the starter. Slide starter towards the motor mount cut the wheels to the left and lower starter throught the linkage. Reverse to reinstall. Sometimes easier if wheel is removed. I use a lift and have not had to do it this way for many years. If this is a v-6 engine and I assume it is you MUST lower the exhaust pipe from the exhaust manifold on the drivers side. Sometimes you need to remove the complete pipe. I usually remove the rubber hangers and let it hang. Tight fit. Be VERY careful with the bolts on the exhaust manifold. This is NOT for the novice.

Where is the catalytic converter located in a 94 chevy corsica?


From the engine, you have manifolds coming out the side of the engine. It will probably look a little rusty. The manifold is the first part of the exhaust system. After the manifold, you will have pipe running below the car. the pipe is bolted to the manifold. After the pipe there will be a larger portion of the exhaust. Kind of an oval shape pipe. Probably roughly 12" long. The catalytic converter gets VERY hot, so let the car cool completely before touching.

WHERE TO LOOK FOR EXHAUST LEAK


There are several areas to check for possible exhaust leaks. i will list them below.

1. Exhaust manifold gaskets - This will be the most common area. There is a gasket that separates the block from the exhaust manifold. these gaskets can fail, thus, causing a exhaust leak at the manifold.

2. Lower manifold gasket(donut gasket) - This will be a possible leak spot as well. This small circular gasket is placed in between the upper exhaust pie and the lower side of the manifold. It basically separates the pipe from the exhaust manifold.

3. Exhaust pipe - The entire pipe can rust overtime, thus, creating small holes along the pipe structure. These holes will cause the exhaust to leak ,thus, filling the vehicle will moderate fumes and causing louder than normal engine sounds during revving.

4. Muffler - This component can also deteriorate to the point that it cannot filter out the noise. It will also cause leaks as well.

You will find the leak in one or all of the areas stated above in the list.

How to replace the water pump on 1993 oldsmoblie achieva.


2.4 enigine is the harder of the 3 enignes. it will need a timing chain to be removed and a coolant tube in the back of the engine to be removed. this job on the book calls for almost 7 hours.

if its 3.3 or 3100 its alot easier.

3100 is just 4 10mm pulley bolts and 5 or 6 small 8mm water pump bolts.

3.3 is alittle more work, but same concept as 3100 engine. more owkr only cause its in a tighter area.

good luck,
michael
