Here’s another set of informative video(s) from the Corvette Mechanic Paul Koerner who is a GM World Class Technician with Key Chevrolet in Middletown, CT. Paul has an Elkhart Lake Blue C8 Corvette at his dealership for a 4-wheel alignment and he uses this new video to show why it takes so much longer to perform the service on the 8th-Gen Corvettes compared with earlier models.
During his series of videos on the LT2 engine swap last month, one of those dealt with doing the four-wheel alignment, but here he goes into greater detail on what has to be done before any adjustments are made.
“Honestly, most of it is because of plastic panels and let me show you exactly why,” says the Corvette Mechanic who shares the following videos to his The Corvette Mechanic page on Facebook. Paul points out the various bolts used for adjusting the Corvette’s suspension and then shows how many of the plastic panels and vents on the car actually cover those points, and the process is even longer if the Corvette has the Z51 Performance Package.
The story is the same as well on the front of the vehicle as Paul shows us where those adjustment points are and how they are tucked under the panels that help control the flow of air under the car.
Paul says he timed the process of conducting a 4-wheel alignment on a Z51 car and that it took him almost three hours to check the trim heights and then perform the four-wheel alignment after taking off all the panels. So if you are planning on dropping your Corvette off for an alignment at your dealership, you will want to account for that extra time.
As a follow-up to the 4-wheel alignment video, there were some questions about the Z51 cooling ducts on the C8 Corvette. There still seems to be some confusion out there by service techs on which ones get installed and what not to install, and Paul clarifies the process.
Paul shows off the GM tech instructions for the rear brake ductwork and Chevy does show that there is a Rear Knuckle Mounted Cooling Duct that is required and installed during the Pre-Delivery Inspection (PDI). It’s the Rear Lower Control Arm Cooling Ducts that are supplied to Z51 owners and they are for track use only.
Thanks again to Paul Koerner for offering these short but highly informative videos as there is a lot to learn with these new Corvettes.
