Chevy Suburban



  • you need to bring it in to an oil change outfit. for around $89 they will perform a fluid exchange from a 100 gallon container while the engine is running and the transmission is in park position. This is the only way to flush out transmission fluid in the torque converter. good luck.
  • check your may be not putting out the correct voltage. when you are in the city the engine rpm is very low. with a faulty alternator, you might not have enough juice to your fan blower. worth a try. good luck
  • try to replace fuel filter or fuel may be weak. when you go at higher speed, it require the fuel pump to work harder. i am guessing too!!!
  • it will fit but you don't want to put bigger tires without any don't want the tires to rub the wheel housing if you have a heavy load. good luck
  • both door switches went out on my 94
  • Hi folks! New here... what kind of gas mileage are other 95 Suburban's getting out there? I have a 3/4 ton 4x4 and we live at mile about sea level. I am getting 8 miles to the gallon at best! I do have a little bit bigger tire than stock... Kinda in shock as I just gave up a 16 m/gal 4Runner. My husband's friend says I am getting about right. Husband has already checked the fuel injectors and we are gonna throw on a K&N Filter. Any suggestions out there?

    You should have a look at Chevrolet Suburban and GMC Tahoe MPG - Real World Numbers.

  • Please, please let me know if you figure this one out. I have a 2002 Suburban with the 8.1 liter engine that just started doing the exact same thing. No engine codes or nothing. I have been bleeding the fuel line before every start by using the little tire valve type bleeder on top of the fuel rail but now realize that probably isn't doing anything more than just the mere passage of time. This is an extremely aggravating problem as it is the wife's vehicle and she is not well equipped for getting stranded. Any help solving this one may actually help many of us.
  • I have a '94 with the big block and I only get maybe 8 to 10 mpg. I have an open flow K&N, Doug Thorley headers and a custom dual exhaust. Added a little horse power but not much in milage. May want to try the 6 pack computer module (I think Jet Performance makes it) that will let you dial to economy settings when on a long trip to save a little.
  • Have U tried hitting the bottom of the fuel tank? Have U tried using ether? Is there spark when it's trying to start? How full was your tank? Used drygas?
  • I get 12 to 16 mpg with a 1/2 ton 03 4x4. You might check your vacuum lines for leaks. That could alter the advance timing and cut your economy. It's also possible that you have a restriction in the exhaust that cutting power. See if there's a pressure buildup compared to other vehicles. Your cat. converter could be clogged.
  • First, check to make sure you have good vacuum. Next, I had a problem with the selecter vent just inside the firewall from the blower. The vent deflector is made of fiber and the control is metal with rivets. The rivets pulled thru and the vent would not shut completely. This left air flow where it wasn't selected for. I made a tin clip to fit over the top of the vent and riveted it on. Also, the ductwork going up to the defroster is a poor design and leaks air the whole way around at the connector. This was the same on every Suburban I checked. You have to wrap the ductwork with a sealer tape. Hope this helps.
  • I also have a 2001 3/4 ton Sub. with the 8.1L and I do have the same intermittent starting problem. It seems to be a fuel delivery problem, if you use ether it will usually start and run fine. In my case I know it's not the fuel pump, filter or in any of the lines, it seems to be the computer control for the injectors. For what ever reason, it doesn't seem to get enough fuel to start (or possibly start for 1/2 a second & die). I did change the throttle body for another reason and the problem dissapeared for about 1yr. then it came back. It could have something to do with that.
  • again I have an '01 3/4 ton 8.1L it has a clunk in the front end when you take off, let of the gas quickly or hit a bump the right way. I replaced the intermediate shaft & the ball joints, checked the steering linkages even the pitman arm & idler arm. I am @ my witts end, please help me!

    Freeze plugs are located in the engine block below the heads, they are round metal cup-like plugs. If cracked(I've never seen this, more likely dislodged) you will see fluid on the floor of your garage. not hard to replace, but might be hard to access. to replace. use a long punch and hammer. tap in one side of plug, when it is knocked in grab the edge with pliers and pull it out. to replace, line it up and tap in with hammer until flush with block. they also make rubber center ones that slip in and tighten with a bolt that is in the rubber
    . hope this helps

    Hello. I am shopping for an 04-06 Yukon XL/Suburban, 1/2 ton 5.3 with SLT/LT package. Part of the reason for the purchase will be to tow a travel trailer, so I want to make sure I buy something with the necessary hardware for towing. Does anyone know if there was a "tow package" for trucks in these years, and if so, what parts did it add (trans. cooler, class IV hitch, trailer brake pre-wiring, 3.73 or 4.10 gears, ect). What is the "trailering preparation package", which the trucks I drove (05 'Burb, '05 YXL, '04 YXL) appear to have (I have noticed that every truck I have looked at had a receiver w/ 7-pin harness, but I have not remembered to look for a transmission cooler.)

    Of course, the salesmen are little or no help in answering these questions, and just "assure" me that it will do the trick, so I though I'd ask you all.

    Thanks in advance.

    I have an '06 Chev Suburban LS with the 5.3 engine and 4 x 4. Here's what came standard: Smart Select Package, includes (AJ7) Air bags, side-impact, (PDC) Cargo Package, (G80) Differential, locking rear axle and (Z82) Trailering equipment, heavy-duty, includes trailering hitch platform, 7-lead wiring connector, auxiliary transmission oil cooler and trailer brake pre-wire harness.
    This equipment is standard on all LS 4 x 4 models, not sure about 2 x 4. I have the 3.42 rear end gears. For serious trailering you should probably opt for the 3.73 gears that are available in the 1500 series (1/2 ton). I think you might even be able to get 4.10 gears in the 2500 series (3/4 ton). The 2500 series also offers a bigger engine.

    Fuel is seeping up through/around the purge valve cap. I've replaced the valve, cleaned the unit, to no avail. Can I replace it with a newer version filter/separator unit? Any suggestions/advice will be greatly appreciated!

    I just got my truck back from the dealer and it seems that there is an electronic module that puts out 5V DC to start the engine but then the voltage should change after starting. On my Sub. it didn't change causing it to start and immediatly stall. They told me it was due to the remote car starter but it seems that the unit can also be defective as they replaced mine.
