What am I looking at? Underside labeling for a newbie
Hi everyone,
I'm a new member and hopeful owner-to-be (currently shopping). I've loved cars my entire life but haven't really had the chance to learn about them. I'm trying to get started by learning the various parts. Can you please help me by telling me what these parts are, as viewed from the underside of a C6?
I'll post my guesses for your enjoyment. ;-)
Thanks,
T.
----------------------------
A - catalytic converter?
B - oil filter
C - bottom of the engine block? or something to do with transmission?
D - small pipes. no clue.
E - hole. no clue. (why is there a hole?)
----------------------------
F - exhaust tips?
G - something to do with exhaust. "manifold"?
H - sway bar
I - black bar going across. something to do with brakes?
J - branch of the axle, maybe. does it have a specific name?
K - (see J)
L - black thing. gas tank?
M - silver pipe. no clue
N - cool-looking shell-shaped thing. differential?
O - black cylinder with yellow label. strut?
P - black tube. no clue.
Q - axle?
R - squat gray cylinders. no clue.
Thank you so much for your knowledge!

A, F, G, and M are all part of the exhaust system.
A = merge collector on a header. The header is a more efficient exhaust manifold and is not stock on the car. The merger collector takes the 4 pipes coming from each cylinder on that side of the motor and combines them into one pipe.
After the merge collector, the exhaust gas (and sound waves) flows to the back of the car in two pipes, which is M in your diagram. The pipes in the middle of the car are sometimes referred to as the intermediate pipes.
Those pipes ultimately connect to to mufflers, item G. Baffles (and sometimes fiberglass or materials) in the muffler absorb sound and make the car quieter.
The exhaust gas and remaining sound exit through the exhaust tips (item F).

----------------------------
A - catalytic converter? = Exhaust header pipe, specifically the collector portion.
B - oil filter = Correct!
C - bottom of the engine block? or something to do with transmission? = engine oil pan, the "bolt" immediately in front of the filter is the oil drain plug.
D - small pipes. no clue. = transmission cooling lines; circulates transmission fluid to a oil/water heat exchanger hidden inside the right side of the radiator. found on Z51 models. Incidentally the small tubes on the opposite side of the engine and just above the oil filter are for engine oil cooling. similar to transmission in that is uses an oil/water heat exchanger hidden inside the left side of the radiator.
E - hole. no clue. (why is there a hole?) This whole portion is the bellhousing, contains the clutch, friction disc and pressure plate. The hole is there as a vent and you may see some black powder which is a mixture of clutch dust and road grime.
----------------------------
F - exhaust tips? =Correct again!
G - something to do with exhaust. "manifold"? = muffler; one for each side of exhaust, or "dual exhaust"
H - sway bar = yes.
I - black bar going across. something to do with brakes? = the leaf spring; an unusual setup somewhat unique to corvettes but not most other sports cars.
J - branch of the axle, maybe. does it have a specific name? = J actually points to the lower control arm but I assume that is what K is intended to point at, so yeah it is the axle. Also called half-shaft, is a black steel rod about 1" in diameter just above and centered front/back above the lower control arm, it runs from the differential to the center of the wheel.
K - (see J) = lower control arm, it has two branches and looks like a wish bone. thus 'wishbone suspension; or double wishbone because there is an upper and lower one.
L - black thing. gas tank? = left side gas tank; there is a right side one as well.
M - silver pipe. no clue = exhaust pipe from header in front to muffler in back.
N - cool-looking shell-shaped thing. differential? = that is the transmission; the differential is immediately behind it and they kinda look like one unit because they are bolted together. If you look closely, there is a seam in front of the rear cradle where they join.
O - black cylinder with yellow label. strut? = shock absorber
P - black tube. no clue. = rear toe link. because these cars have 4 wheel independent suspension the front and rears need to be aligned to point straight.
Q - axle? = rear cradle. made of aluminum, it is what all the suspension and transmission/differential bolts to. This is then bolted to the frame.
R - squat gray cylinders. no clue. = NPP actuation valves. It is what makes the exhaust get loud over 3000 rpm or when you floor it.
This car must be a 2008 or newer with NPP and Z51, correct?

What a refreshing post and I applaud you for being willing to learn more. We all started at the same place - no one is born knowing about cars.
Cheers,

C is the oil pan.
D looks to be oil lines that come from the trans to the cooler inside the radiator, I think. If it's a Z51 car, this could be the case. If you look at the trans in the back, you can make out the sames lines there.
E is the bell housing cover for the clutch, holes are there for cooling This is a manual shift car with a six speed trans.
I is the rear left spring, made of a composite fiberglass of sorts.
J and K are the same thing called the lower rear control arm.
L is the gas tank, made of some high tech plastic material.
R looks like your pointing to the muffler hangers made of a rubber material.
Q is the rear cross member section.
P is the rear tie rod, it's adjustable for alignment purposes.
O close but corvette have shock absorbers not struts.
N is the transmission follow by the differential, the thingy with the X mark on it's pan cover in between the mufflers.
Anything that I did not mention, you got right. Congratulations on that part.

Wow! Thanks for the great information. A couple clarifying questions:
1. The cooling lines that run from the transmission/engine to the radiator... so there are two sets of such lines: ones on the left by the oil filter that carry engine oil to the cooler in the radiator and ones on the right ("D") that carry transmission fluid to a different cooler? Or do the ones on the right carry oil but from the transmission and not the engine?
2. Is I "rear leaf spring" or "rear left spring"?
3. Is P "rear toe link/rod" or "rear tie link/rod"?
I don't know - it's not my car. Just a pic I found on the Internet.

the spring is one only, leaf not left, sorry.
left side is the engine oil lines and right side is the trans lines, yes 2 different set of lines.
Tie rod link is the center part and at the end is the tie rod end.
It's used to set the "toe" alignment spec. Confusing cars can be.

Or do the ones on the right carry oil but from the transmission and not the engine?
The two lines that run from the transmission (in rear of car) up to the passenger side of the radiator) are for the transmission oil. I never quite understood the need for this on a manual but if anything it helps warm the oil up a bit quicker which IMO makes it shift smoothly more quickly. One line carries oil to the radiator, one carries it back.
There are also lines on the driver side that start at the engine and go up to the radiator. These are oil cooler lines.
(some models have one or both of these while others have none..)

... is oil used to lubricate any system other than the pistons/cylinders/engine itself?
Ah, as in camber and caster. Thanks!

Trans fluid and the engine oil is used only to lubricate the internals parts of the engine, so yes to that question. pistons ,bearings, lifters, rocker arms, and so on.
Yes to camber and caster are the other 2 important alignment specs.

Engine oil is only used for the engine. Transmission only for transmission, etc.

You picked a car that has a lot of extra features that most cars do not have. If you learn the corvette, you will be one ahead of most people's knowledge of cars....
