No, it just makes for a better look for the engine.
We have a 3.8 Supercharged Indy 500 edition SS and it's located under the plastic engine cover on the top of the engine. Remove the plastic nut that holds on the cover with a 1/2" socket. The EVAP solonoid is on top-middle of the engine towards the firewall. You will only need a screwdriver to pop any retainer clips to remove the solonoid. It's a 5 minute job!
They are in the center of the Valve cover, under the plastic "chunks" that are the ignition coils. You might need to remove the plastic engine cover first. There are several plastic clips you need to turn part way to remove this part.
Need to specify a model year. BIG difference between an Impala from the 1960s and an Impala from the 2000s.
Underneath the radiator in the driver side. It is facing inside the engine. meaning, you need to bend the splash mud cover under the car a little bit to be able to feel it....not see it. it is plastic and it shaped as a butter fly screw cork.
PCV valve is located in front of the engine, behind plastic (long and narrow plastic cover that covers valves and fuel lines). You need to remove one hex screw that attaches plastic cover to engine and remove plastic cover. You will see pcv valve 3-4 inches to the right of the hex screw that was attaching plastic cover to engine. Once removed you will see silver pipe at the end of the pipe plugged in engine sits PCV valve. PCV valve plugged into engine by it's mettalic side, so only plastic side is visible. Easiest way to understand how PCV valve sits is to buy new valve in auto parts store, remove plastic cover that covers fuel lines in front of engine and find a part that looks like PCV valve.

One is hidden under the plastic engine cover, the other has a longer filler neck which goes through the engine cover so you don't need to remove the cover to top up the oil.
You need to take off the cover from your engine and then you will see a plastic cover with aprox. 6 screws you need to take out those screws and under that you will see the spark plugs
You need to remove engine cover first. Engine cover is the plastic cover with VW logo on it. The air filter is installed in the cover itself. You can find *very* good DIY info here: http://forums.vwvortex.com/zerothread?id=2547554
There is a plastic cover in front of the engine. Under the cover is the intake manifold. After you have removed the plastic cover, then the intake manifold you will see the starter. Before you can remove the starter you will need to remove wires tubes and linkages. It will take a few hours if you are good.
A blown fuse will cause your 2000 Chevrolet Impala interior lights to stop working. The fuse box can be located in the engine compartment. A listing of the fuses can be found on the inside cover of the fuse box.
You do not need the plastic cover on the undercarriage of the Beetle necessarily. It is designed to protect the undercarriage from road debris but it is not necessary to the function of the car.
