C5/C6/C7 Engine Cleaning

Whether prepping your Corvette to roll across the auction block or display at a show, cleaning the engine adds value. A spotless engine shows just how important and well maintained is your Corvette. Filthy engines are more apt to retain heat and make it difficult to detect small leaks. Dirt and dust cause pulleys and belts to squeak from undue wear. Worst of all, it just looks bad. (more…)

C5 Oil Pressure Sending Unit Replacement


If you haven’t already replaced the oil pressure sending unit (CC part # 305254) on your C5 Corvette, it will become a necessity when the gauge stops functioning properly. One telltale sign is the oil pressure gauge needle leaning past the high mark at all times or not moving from the lowest point. Another sign is an oil leak near the rear of the oil pan. Many times, the presence of oil is mistaken for a leaking rear main seal; always look at the top of the bellhousing for the source of a leak. If there is a trail of fresh oil cascading over the bellhousing, chances are the sending unit is leaking. Sending units have an immediately noticeable leak, whereas rear main seals usually experience a slow leak that increases over time. (more…)

1997-2013 Rear Anti-roll / Sway Bar Link Replacement

When we had a chance to look under the first C5 in 1997 it was hard to believe a performance vehicle would have a plastic anti-roll (sway bar) link. To make things difficult lock nuts were used to hold the links stud into the control arms. That meant when someone removed the end link chances are they would rip the joints seal because they did not hold onto the stud during removal. The original plastic sway bar end links flexed under hard cornering making the anti-roll bar less beneficial. Of course a hard driving Corvette owner might break one or more on a track day. By 2002 GM finally dropped the plastic pieces replacing them with an aluminum anti-roll bar end link. One of the few things that did occur positive is the same end link is used from 1997-2013 so you can easily find and replace the weak original 1997-2001 links. If someone was not being careful and tore the end link seal during suspension service you may need to replace one or more on your 2002-2013 Corvette. (more…)

1997-2013 Shock Absorber Information and Replacement

Shock absorbers are considered a consumable product with a limited lifespan here’s why…

Shock-mono-tubeThe C5 Corvette shock absorbers and C6 Corvette shock absorbers are both Mono-tube design. Mono-tube shock absorbers construction begins with a single cylinder (tube) filled with hydraulic fluid. Another piston is used to separate the gas charge from the oil charge. Together the hydraulic oil and high pressure gas with proper valving dampen suspension oscillations. The rod that protrudes out of the cylinder is connected to a piston with seals to keep fluid in check. Another seal is used at the end of the cylinder where the connecting rod comes out to keep the fluid and gasses in while trying to keep debris out. One of the major benefits of mono-tube shocks is the pressurized gas is separated from the oil via a piston. The constant gas pressure on the hydraulic oil minimizes aeration of the hydraulic oil preventing foaming. Foam affects shock absorber performance because it can be compressed while fluid cannot, in turn; the shock reacts quicker with predictability. Overall suspension performance is enhanced with quicker reaction times with the tire on the pavement as much as possible. (more…)
