You still have to remove the transmission on a van to access the rear freeze plugs.
Freeze plugs, also known as core plugs or expansion plugs, on a Mercury 350 V8 boat engine are typically located on the sides of the engine block. They can also be found on the cylinder heads, depending on the specific engine design. Their primary function is to protect the engine from damage due to freezing by allowing coolant to escape if it expands when frozen. To locate them, check the sides of the engine block and the rear of the cylinder heads for small, circular metal plugs.
On a Cadillac DTS, the spark plugs are located under the engine’s plastic cover, which needs to be removed to access them. The engine is a Northstar V8, and the spark plugs are positioned on either side of the engine, near the cylinder heads. You'll need to disconnect the ignition coils to reach the spark plugs for replacement or inspection.
i would check the freeze plugs on both sides of the side of the engine block.
The 2005 Cadillac SRX has a V6 engine.
The Lincoln LS 3.9 liter V8 engine has ( 8 spark plugs ) It depends on the V8 engine , it could take ( 8 spark plugs ) but there are also V8 engines that have two spark plugs per engine cylinder so they take ( 16 spark plugs ) A little more information please ( make , model , engine size )
To replace the rear freeze plugs on a 1997 Dodge 318 V8 Ram Van, first, ensure the engine is cool and drain the coolant. Remove any necessary components obstructing access to the freeze plugs, then use a punch to carefully tap the old plugs out. Clean the area thoroughly before inserting new freeze plugs, ensuring they are seated properly, and then reassemble any components removed. Finally, refill the cooling system with coolant and check for leaks.
you remove the "air"(sai) valve
