It is your choice. You can either remove the transmission and leave the engine alone. or pull the engine and leave the transmission alone. If your SMART you will replace all the freeze plugs in the engine.
The hardest part is getting to them. You have to be able to get clear access to the freeze plugs. There are typically several, and often there are a some that are difficult to reach. You'll need to look at a reference manual to see where they all are. Sometimes you have to pull the engine to get to the freeze plug that is under the flywheel/flex plate. It depends where the freeze plugs are located. I just recently had the rear plugs replaced on my ranger v6 3.0 and you cannot reach them. I had a shop do the work and instead of lifting the engine out they dropped the transmission and was able to reach them from underneath.
On a 1991 Buick Roadmaster, the back freeze plugs are located on the rear side of the engine block, typically near the bell housing of the transmission. There are usually two freeze plugs positioned on the back of the engine, allowing coolant to circulate and prevent freezing. Accessing them may require removing components like the transmission or exhaust system for better visibility and reach.
By disconnecting the top motor mounts you can tip the motor to the front . This will give you the room you need
there are 6 spark plugs, 3 are visible and easily changed, but 3 are under the engine and very difficult to get to. I had to have a shop do the work and they said they had to pull the motor to reach them.
The rear plugs will have to be reached from underneath. The engine will need to be unbolted from the motor mounts (while being properly jacked up) and leaned forward. There is a special wrench used to reach up and get to the plugs at this point.
Bars Stop Leak is a good leak fixer for small leaks and leaks in really hard to reach places, like heater cores inside the vehicle and clean-out/freeze plugs on the back of V- engines where the transmission blocks access to them. Hoses are fairly inexpensive. So, what's leaking?
On a 2001 Oldsmobile Alero, the freeze plugs, also known as core plugs, are typically located on the engine block. You can find them on the sides and rear of the engine, as they cover the gaps left from the casting process. They are usually round and made of metal, designed to prevent coolant from leaking and to allow for expansion of the engine block when freezing occurs. Accessing them may require removing certain engine components for better visibility and reach.
On a 2003 Pontiac Montana, the freeze plugs are typically located on the engine block, usually on the sides and rear. They are designed to prevent engine block damage from freezing coolant. You may find them on either side of the engine near the cylinder heads and at the rear of the block. Accessing them often requires removing other components for better visibility and reach.
The freeze plug on a 1996 Saturn SL1 is located on the engine block, specifically on the sides of the block. These plugs, also known as core plugs or expansion plugs, are typically situated towards the rear and sides of the engine. To access them, you may need to remove other components, like the intake manifold or exhaust parts, depending on which plug you are trying to reach. Always ensure the engine is cooled down before attempting any work on the cooling system.
On a 1998 Oldsmobile Silhouette, the freeze plugs, also known as core plugs, are typically located on the engine block. You can find them on the sides and rear of the engine, usually near the cylinder heads. They help prevent the engine block from cracking due to freezing temperatures by allowing coolant to expand. Accessing them may require removing certain components for better visibility and reach.
hi there,to replace the rear spark plugs you virtually reach over the motor and do everything by feel .it is quite an awkward reach to get at them,but the hardest one is the one closest to the drivers side. there isn't much room.if it helps you can also hang a small mirror there and this helps a bit to see what you are doing.hope this helps.

I have a 1991 Cutlass Supreme and I had to use a flex ratchet to replace the back 3 plugs. Other than that I was told by a mechanic friend that the motor has to come out to do this.
