HI there, ESI, or electronic service information is usually on a disc that is then uploaded to a given computer and used. This is a DIFFERENT system than what is used by GM service departments. This is usually an ACDelco type of access like "techconnect". GM dealerworld is a broadbased...

Details Hi there, Please lets clarify a few things. #1, your best camber setting for optimal tire wear is 0.0. #2, just because you have FE3 DOES NOT MEAN all specifications are -.45. If you have RPO XFA for a tire size in the front, that specification CHANGES to -0.95. So, as far as...

WAIT WAIT WAIT Lets get back to basics. If you are seeing a "no fob detected", there is some type of interference creating a problem. When this happens, are you installing the key fob into the glovebox pocket with the buttons to the RIGHT and then trying to start the vehicle????? If your...

Hi there, Z51 and Grandsport suspensions are a night and day difference. Remember that GS suspensions are essentially ZO6 without the aluminum frame. Z51 is not as rough riding, nor is it as good when cornering as GS. Sway bar diameter, shock monotube diameter, spring rates are all...

Ha, thanks Dwayne. Yeah, still dont really know why my big mouth keeps getting invited back, but hey,,,, why not?? Just look for the black Certified Service uniform and the bald head!!!!!:hb I will be there with 2 students, Alex Sutherland and Brittany George, to immerse in C7 and assist all...

HI there, Well, first off, is that the original gas in there?????? 2012, and 130 miles, I would think yes. If so, I would start by checking the fuel quality if there is any contaminants. Yes, I do agree also that fuel pressure should be checked also. I would also want to know, how long are...

I agree with most all the sentiments here. Regardless of anything, his love of the technical aspect always came from within, not some trumped up wanna be who just wants to be a know it all. He studied and worked so very hard at everything he did. While we always would challenge each other...

HI there, Tenneco/Walker exhaust systems have been on Corvette for years and years. Solid, reliable and the company which manufactured the titanium mufflers on the 5th generation ZO6. I virtually NEVER see problems with their systems. It will be enjoyable to see it up close in three weeks...

Hi there, Ok, first, lets start with the basics. I see 3 things that make me wonder. #1, Was a fuel sample taken ????? You had 2 gallons left, which tells me that there is not a low fuel LEVEL problem, but maybe a fuel QUANTITY or QUALITY problem. Ethanol more than 10% can yield...

Hi there, Also an important point to remember, the electro plating of the sparkplugs on OEM applications IS an anti oxidation coating. This is why YOU NEVER EVER use a wire wheel to clean the threads, as this process takes off the electro-plating and thus the antioxidation characteristics of...

On a side note: HAS IT BEEN 3 YEARS SINCE WE DID THAT SEMINAR??????!!!!!!!!!! Where has the time gone? sheesh!:hb

This information on the 78PS does NOT apply to your 2004. That battery in your vehicle should be an 86PS because you have top post battery terminals. Allthebest < Paul

HI there, There are no repair techniques or material breakdowns of the windshield frame assemblies within GM service information. They only specify entire frame replacement, as it is bonded and bolted to the lower frame assembly. The picture is a breakdown of the assembly. #3 is the entire...

Hi there, Now your really opening up a can of details. First off, the seals that you are talking about are 2, the oring that goes around the entire circumference of the side cover and the axle shaft seal itself. Now, do NOT, I REPEAT, DO NOT use the procedure in the service manual. It has...

HI there, And my .02 here. And everyone is forgetting the immense increase in quality through out the entire GM product line. Having served GM and its customers since 1997, I can personally attest to it. Lower warranty repairs across the board, and much less for me to repair. Nevermind the...

HI there, Ok, so here is the low down on this. The basic reason why they do not give you a procedure is because essentially, they want you to pull the unit so that you can get the correct install depth for the output shaft seal. However, this is how I do it and it should work for you if your...

HI there, JUST had an idea: Please private message me your VIN, so I can give you actual diagrams from GM parts so that there is no discrepancy between what you see and the information I give you, OK ? There is NO information within the Corvette service manual to replace the output shaft seal...

Hi there, Lets clear up a few things here. #1, there are 3 seals within the area in question. Transmission output shaft seal, differential input cover oring and differential input shaft seal. The accompanying picture is the input cover with input shaft seal. As far as fluid transfer, it...

Just a thought here. #1, dry sump engines fill at the reservoir at the pass side firewall. #2, NON dry sump engines fill at the right side valve cover and when they spill oil, it drips on the EXHAUST manifold. Just a thought, Paul

HI there, Your key MUST be your engagement point, as a worn clutch will engage from half way to the top of travel. If you are engaging 1-2 inches off the floor, a worn clutch is not the issue. As long as the clutch fluid has been changed every 2 years with DOT 4 fluid, its most likely a...
