if its a 3.1, the possibility is the intake manifold gasket!!
Depends on the vehicle. There is one on the passenger side which is the front of the engine, but could be considered the upper right. There may also be one at the front of the car that connects to the radiator support that would be the front one.
The subframe would be the same. The only thing with different engines would be engine mounts. But that has nothing to do with the subframe.
follow the upper radiator hose it would be right at the end of that
Plugged catalytic converter?

What would make your speed odometer stop working after putting an alternator on? 2005 Chevy Malibu
it should fit,the mounts are the same.
That depends on what website you are talking about, it is mostly upper right or upper left. For example if you are talking about NeoBux then it would be upper right.
That would depend on the year and engine size. If you do not see a distributor then it is distributorless ignition.
because the engine in that car does not cool down
You would need to call a parts house and they can answer that for you.
In most cases if your follow the upper radiator hose from the radiator to the engine, the thermostat would be located inside the "gooseneck" at the engine end of the upper hose.
