#509 of 607 Surburban 2001 Preventative Maintenance
Nov 24, 2009 (7:29 am)
I have a question regarding my maintenance schedule for my 2001 Suburban. Can you help?
Our Chevy Suburban 2001, 1500 (4) wheel drive has 92,000 miles. Our last preventive maintenance (major) was at 5/5/2006, (66,500 miles) which included Transmission and Differential major preventative service. The scheduled service manual state the service for this preventive maintenance is every 50,000. The truck is currently consumed 50% of that time for these services.
Question: Is it your recommendation to wait another 2.5 years assuming we are driving the truck 10,000 miles per year?
Thank you for your help,

i think you can pull off the vacuum hose to the regulator and if you see fuel in there, it's bad for sure.

Not sure if this will help but look at the recall Chevy had in October 2005 on the fuel module resorvoir. Certain 2001 models had prbolems with the fuel pump when the gas went below a quarter of a tank. My will cause a fuel stall or no start condition. My wires overheated in a gas station burning a hole in the connector body and I dumped fuel while on vacation in Florida. A nightmare of the 4th of July weekend with Hazmat etc. however, Chevy picked up the tab. I believe this is the problem and you may be able to get Chevy to cover the issue. Good Luck.
#512 of 607 2000 Suburban - stereo security code?
Dec 23, 2009 (11:28 am)
I just bought a 2000 Suburban from a private party. It has a factory stereo with some sort of security code system. Unfortunately, the previous owner had gotten locked out of the stereo and didn't have the code to get it unlocked. So 2 questions:
1. Is there some way to get the code? or to get around this problem?
2. How do you go about unlocking the stereo even if you have the code?
btw, I live in Central America. No GM dealerships nearby...
#513 of 607 100k Maintenance on 2004 Sub
Jan 14, 2010 (3:25 pm)
My Sub is at 98k miles, so I'm preparing to do the big maintenance service soon. Per manual, major points are: plugs, air filter, trans. service, transfercase service. Manual recommends changing coolant at 5 yrs/150k miles or something like that, so I figure I'll do that, too. I am familiar with cars and worked on older cars & jeeps quite a bit in the past, but aside from changing the evap sensor soleniod or whatever it was called, I haven't done anything to this truck except change the oil, which I usually do myself (haven't needed to do anything). I'm considering doing plugs, filter, and coolant myself this weekend to save some money (I won't touch the transmission or transfer case), and looking for guidance. A couple questions before I start:
1) with the rear heater, is there anything different that needs to be done in changing coolant (I assume there is separate heat exhange at the rear of the truck)? Or do I just flush, etc as usual?
2) any tricks to getting those rear spark plugs out? They sure look like they're in tight quarters. We had an old Bonneville w/ 305 engine, had to take the passenger tire off to get at the plug. Any similar tricks on this engine?
Any other tricks or tips appreciated! Thanks in advance.

Unlocking a Radio That Displays LOC When Code is Unknown
IMPORTANT: Starting in 1995, a factory back-up code can be used to erase the original code if it is unknown.
Have account number ready to enter when asked. Account number is your five digit dealer code followed by one of these numbers:
* Chevrolet - 1
* Pontiac -2
* Oldsmobile -3
* Buick -4
* Cadillac -6
* GM Canada -7
* Saturn -8
Read all steps before starting the procedure.
If more than 15 seconds elapse between any of the steps, the radio automatically reverts to time and you must start the procedure over from step 1. In order to unlock the Theftlock(TM) system when code is unknown, perform the following steps:
1. Press and hold push buttons 2 and 3 until a three digit code appears on the display.
2. Write the three digit code on a piece of paper.
3. Press the AM/FM push button, a three digit code will appear on the display again.
4. Write the three digit code on a piece of paper.
5. Call Delco Electronics at 1-800 - 537 - 5140.
6. Follow the computer prompts to obtain the back-up code to be used in place of unknown code.
7. Press MN and 000 will appear on the display.
8. Press and hold MN until the last two digits agree with the back-up code.
9. Press and hold HR until the first one or two digits agree with the back-up code.
10. Press the AM/FM push button after you have confirmed that the code matches the one you wrote down. If REP appears on the display, repeat steps 7 through 10.
11. The display will show "- - -" to indicate unknown code has been removed.
If the back-up code does not unlock the radio, try reversing the first and last three digits of the display code.

Don't know for sure, but wouldn't you be able to get to it by dropping the transmission instead?

Yes you R&R the transmission and either clutch or flexplate depending on transmission.
Book says that for manual transmission it takes a professional mechanic with all the lifts, tools, etc. about 3.6 hours and for the automatic, about 6.5 hours.
