  • Underneath of C8

    Are there photos of the underneath of the C8 ?, I’ve heard it’s nearly flat , but have yet to actually see it.

    The only pictures I have seen are the ones that Jag took of cutaway car on it's side at the reveal in Tuskin

      I did hear the belly pans for aero are able to be loosened and removed while on the lift which is a smart move...

      gM is always thinking about service ease for its warranty labor claim time

      another interesting fact that I saw at key chevy corvette technician Paul Koerners service seminar on the c8 showed quite a lot of future service items were down low.

      yes the bellypans come off and then it looks like a lot of basic service items are down low..ie coils etc..see,ed to make service easier from below the engine ...

      i dont think we are going to see the engine compartment hood open and the service tech reaching in from above.


      i could be wrong but thats my interpretation of the few photos and discussions we have seen ..so far..

            My mistake John. I forgot you took the photos and Jag did the video. It is also the only picture of the fuel tanks. Thanks

              Not important who get credit. What is important is that Jag does an outstanding job for our Corvette community in helping us all learn especially at major Corvette events — and why he is our forums “Events Correspondent.” He is invaluable for all of us learning.

                Interesting. I see openings right underneath where the LT7's turbos will hang.

                  On a mid engine you will rarely see a tech work on anything from above. And if you do be careful or I hope they are careful. The thing that I do not like is when accessing the front of the engine as some components are to the front. , the seats and carpeting has to come out.in some mid engine cars. .

                    I'm hoping with the extra 5" length of the C8 compared to the C7, that GM left a couple of inches more between the front of the engine and the bulkhead, thereby giving techs a bit more room to fiddle with things like belts without having to drop the engine. I recently had the harmonic balancer replaced on my C6 and the labor required was bad enough for a FE car, a ME could be worse.

                    When somebody gets a car they can freely poke around, it would be interesting to see if the carpet on the passenger compartment rear bulkhead can be unfastened and pulled away to reveal an access panel to the engine bay. Kind of like what Ferrari did with some of their earlier V8 models. That would give us a clue about how GM expects to service the cars.

                      Access to the front of the motor in the Boxster/Cayman is through a panel behind the seats, the seats do not need to be removed. I’m sure GM has something similar as do most every mid engine car.

                        That's a neat trick. Basically a pass through in the firewall?

                          I had a chirping air conditioner belt which was caused by a wobbling harmonic balancer i think two years ago...i think the car guys in the internet over dramatized the harmonic balancer issue with regards ti destroying an engine. I just found the first five minutes of chirping as it sounded kind of cheap as i drove the car for the first five minutes but it only happened at first start up of the day...

                          that wasnt inexpensive to do and I was advised to not use an oem part and followed that advice...im glad I did that replacement so Id get rid of that few minutes of early morning chirping ac belt...

                          your right the front end did have to be torn apart.

                          with the c8 I believe the bolt down engine drop will be four hours of labor...

                          how much extra labor over the front end disassembly of the c6?

                          an extra 2 hours if access is nit available with the rear mid engine is in place? I dont know.

                          i looked at the photos of the engine and Im not a tech..it seems there are many parts moved down low ie. Coils etc

                          hopefully parts relocation will help....

                          thank goodness GM made the simple smart move the aero panels cant be dropped with the car on the lift.

                          decades ago inhad a rear mid engine turbo lancia scorpion and we eventually left the aero belly pan off because to service the car..lit was an annoying two step process...put the car on the lift, loosen and remove the bolts...then drop the car on the lift to be able to get the bellypan off....then back up on the lift...it was annoying to the point...the belly pan was left off...

                          chevy was smart making the pan able to come off on the lift...imo

                            After looking at the cutaway C8 at Carlisle, there is no removable access panel behind the seats. But Tadge said you can change the belts without dropping the engine. I assume from below.

                              I think the only way that can be done is someone 20 years old that is double jointed :-)

                              Just look what it would take to get into opening of throttlebody to clean it
