I was wandering who to talk to about discrepancies between EPC and SI. This week I had a customer bring back a 2010 Chevy Express 3500 Diesel, Last 8 are A1180332, come back with fluid coming back up the PS fluid reservoir after replacing the pressure hoses. Not being the original tech I checked to see if the piping was correct. Normally I get the diagram from EPC because for lines it is usually the most clear, showing all the lines in one pic unlike SI, ((which should have this pic under component locator,(my opinion)) and the pic shows the lines are reversed on the gear. Checking SI doc 2123783 (a grainy pic) shows they aren’t reversed. Checking a like pickup, same year, shows the correct routing. The issue was resolved by bleeding the system, there was air trapped in the accumulator I believe. The EPC doc I printed out is TG06-002.

I remember some years ago ther was an article about diagnosing crankcase pressure using a slack tube manometer, I have searched the archives but can not find it.
look at Doc #727092
I, ve noticed one thing in SI diagnostic procedure most commonly in ckt system testing. most of the time they are poorly written. why not to performed a loaded test without disconnecting any connectors by backprobing it. and one more thing, why we are not using verus pro snap on checking waveforms on any circuits and components? you always suggest,” if circuit test normal ” replace this components etc……but we can actually see the digital waveform by using advance oscilloscope and graphing multimeter. because in dealership we are not guessing. Like this example” if dtc p2096 replace all fuel injectors. But actually we can graph the waveform using verus pro, and compare the actual to a known good vehicle waveform. Even the Acadia ignition coil problem.by using oscilloscope, the collapsing magnetic field can identify the faulty ones. thank you
I observed that some icon on the techlink did not match their content (September issue) e.g. Repairing I.P. fuse block which when opened, will show “trunk lid does not self-raise. FYI
The website is being updated. Thanks.
In the past I have had problems ordering terminals, globalconnect shows it as an invalid # as does the parts catalog, no acdelco cross and nothing in the kent moore website. Where do we acquire these terminals? Terminal number 12191819 tray 8. Please help, everyone I ask does knot know and ignors the problem.
CAN U SEND ME THE TECKLINK ARTICLE ABOUT TIRES THAT WAS PRINTED SOME TIME AGO. IT WAS ALL ABOUT TIRE SIZES AND WHAT THE SIZES MEANT WANTED TO USE AS A TRAINING REFERENCE FOR OUR SERVICE ADVISORS
I am looking for the video/class link for the J-45096 Trans Flush Machine, thought a refresher course might be in order seeing how I do not use the machine. Can anybody send the link to me??
Is there a way to get the monthly newletter automatically e-mailed to you?
The idea of e-mailing the monthly pdf has been discussed, but it’s not in the plans right now. Thanks for your interest.
Matt H, read the article “Wiring Repair Strategy Update and Parts Information”. It contains the phone number for ordering terminals.
I have been having no luck finding a Technican’s Guide/Repair Manual for the 6 Speed RWD transmission I know GM has one but no one Knows how to get it, Can you Help Me
Thanks Mike V
MATT H. I HAVE GONE TO MOUSER ELECTRONICS WITH GM OR DELCO PART NUMBER. THEY HAVE MOST TERMINALS ALONG WITH MFGS NAME AND TECHNICAL INFO. PRICE IS ALSO VERY RESONABLE.
i too have purchased hard to find wiring terminals and plastic connectors from Mouser Electronics.
Helm Inc used to have those guides but I found them at atra.com
I am looking for an article on how to check tire circumference on a 4wd vehicle by marking the tires and rolling it in a straight line a certain number of tire revolutions, then measuring the difference in tire marks. This was recommended by TAC but I wasn’t able to find it in print. Can you help? Thanks
2013 GMC acadia, with 3000 kms mileage on it. customer complaint ac not cooling at all. a leaking evaporator was the cause. my concern is that the low side service valve port is facing downwards.so what happen is the high side on the top and you have to raise the vehicle up to connect the low side service hose. interesting design.
2014 impala LTZ VIN 1, 2000 km mileage on it, customer complaint abnormal noise from engine compartment when the ac is turn on. upon further inspection, there are pulsation type of noise from suction hose near to the compressor and the noise can be heard inside the cabin. ac system refrigerant and ac lines are all ok. no bulletin. I replaced the ac compressor and the concern is resolved.

I swear I’ve seen a “GM Oil Capacities” chart somewhere on here or maybe on the training site but I can’t find it. Is it still published or has that idea been scrapped? Any help would be greatly appreciated.
