    It's true there are no more new Troopers, but you can still buy a used one. That same poor resale value that worked against you during that lease, will work in your favor when buying a used, late-model Trooper.

    You said 1998 SLX - is that a typo? I thought Acura stopped selling the SLX after the 1997 model year.

    paisan, I was looking at your site the other day and didn't see anything on how to change plugs on the 1998+ Troopers. Do you have anything like that buried on your site somewhere?

    While my wife was sleeping last night, I snuck into the garage to sneak another peak at the coil packs and spark plugs. No, I didn't leave a screwdriver in the engine bay this time, but I did run into another problem.

    First 2 coil packs, on passenger side, came off no problem. No oil in the well down to the plug or around the plug. All I could see down the well was shiny silver metal and the plug itself. Good sign, I thought.

    Problem removing the 3rd coil pack on passenger side, nearest the cabin. Removed connector, unscrewed coil pack. When tugging on the coil pack to get the long tube to release from the plug, the coil pack broke away from the tube. So in my hand I had the coil pack with a little black rubber and a small spring sticking out of the hole in the end. The rubber boot and long tube had stayed down in the well.

    I fussed with it for a few minutes but couldn't figure out how to get enough grip on the boot to remove it and the tube. I ended up putting the coil pack back on and drove the truck 3 miles. All seemed fine. It looks like I haven't done any damage, but now I don't know how to get the boot and tube out of that cylinder.

    Any suggestions? I was thinking about just taking it to a shop and letting them change the plugs and deal with this when they see it. It's a waste of $80-90, though, since you can do the job yourself for $12-25 depending on which plugs you use. It's frustrating and embarrassing to think that I probably lack the skill to change the plugs on a vehicle, when it's such a simple procedure on this truck.

    Spent about 10 minutes looking for this last night with no success. The illustration in the owners manual didn't help. I know it's on the driver side. Also, it's on the front driveline but I'm not quite sure what that means.

    Can anybody point this novice in the right direction?

    But if you want to write one up... :)

    Does it sound like I can write one up? I can't even manage to check the stupid plugs without screwing something up! Any suggestions about what to do with the separated coil pack/boot?

    Go to the front of the truck (looking toward the back of the truck) and find the front differential. It's the big round pumpkin-looking thing that's a little left of center. The differential should have round steel axle housings coming out of both sides that lead to the half-shafts and eventually to the front wheels. If you look to the right of the differential, you will see the SOTF unit integrated into the tube leading to the left halfshaft (but you will be looking to the right of the differential). It has a protective skid plate over it. It's located just in front of the oil pan.

    Does that help?

    I believe the one by the brake booster needs severel elbows to get it out properly...

    As near as I can figure, the SOTF diagram in the 99 owner's manual was made as if the vehicle is standing on the front bumper. If your 98 is the same I can understand your confusion.
    To add to serrano's finding hints, go to the front of the vehicle. Bend down so you are staring straight ahead at the engine oil drain plug. Now look a couple of inches to the right. Next come forward of that position about 4". That boxy thing right there on the shaft is the SOTF. The fill plug is also the drain plug as best I could determine. You access it from the back.

    Your coil pack problem is a new one on me. I guess your experience is a heads up for all of us to be careful when removing the coil pack.
    As to what to do now, you might call the dealer and see if they individually sell the pack AND the boot/tube. If so that might confirm that you haven't done any real damage/give you an idea of the upside dollar cost of this situation.
    You sure don't want to make the situation worse, afterall you still seem to run ok. Then again at some point you will have to change the plugs. Do you have enough room to get a good bite with some long needle nose pliers (e.g. one side of the pliers inside the tube the other outside)? If so you might try them and use a gentle but firm twisiting (kind of like you are trying to unscrew it)/pulling motion. I wouldn't twist/pull too hard as you might break the boot tube. If you can inexpensively buy an individual boot tube that might not be such a problem. However if you have to buy the coil pack that could be a rather expensive whoops. Just my well intentioned but totally untested advise. User discretion is highly advised.

    I found the best way to get the plug by the brake booster is to use 2 half-the-required-length extensions (I think I read this technique here way back when). Namely, feed in the spark plug socket attached to 1 extension. Then add on the second extension and then wrench loose. Pull out far enough to grab the first extension. Remove the last extension while holding the first extension. Then pull out the first extension attached to the socket holding the plug.

    I appreciate it. Just printed them out and will take another look for the SOTF under the truck as soon as time permits.

    Re: coil pack/spark plug - Did a 50-mile round trip tonight, mostly 70mph freeway cruising, and the truck ran fine. So I'm thinking/hoping that, though the boot/coil pack may not be intended to come apart, it still functions once it has been pieced back together (like I did). Therefore, I have done no damage? A call to St. Charles, as breakor suggested, will probably be enlightening re: whether the parts are sold individually.

    There is enough room to play around with a needle-nose pliers. I may try that but was worried about trying it the other day - didn't want to make things any worse than they are.

    breakor, what is the 'required length' extension - 10"? 12"? I've seen those lengths at Sears, as well as 6", 3", and 1.5". Don't recall any 5" though.
  • breakorbreakor Posts: 398
    IIRC, I used a couple of 6" extensions. Assuming my memory is correct, and if you are buying such tools, I suggest you go with a 6" and two 3" ones for future flexibility on other jobs.

    Again, be careful with the pliers and your removal. You don't want to grip too hard either as that might break the tube boot.

    You might want to try and find someone else who is changing plugs and do an install fest. Or, at least some real world experience on how hard to reinstall the plus, tips to not cross thread, etc. before you tackle this job. It just seems that you are cursed when it comes to repair lately and could use such hands-on teaching help.

    When I bought my truck, it had almost new (<200 miles) Michllin 245x70x16 (standard stock size) in the front. Now, I need to replace the back (the front is still in very good shape, only 1500 miles on tires), and I like a few tires in the 255x70x16 size with more aggressive tread pattern for snow and ice. Would this create a problem other than I won't be able to rotate the tires?

    Thanks

  • sbcookesbcooke Posts: 2,297
    I wouldn't. 255/70's are close to the stock size, but still some difference that could cause a problem. My fronts get cupped more and more as time for rotation nears. I don't think you can go more than 10K without needing to rotate.

    With 1500 on the front, it is a good idea to only do 2 and not all 4 because the new ones will catch up very quickly.

    1998 Trooper S 4x4 SOTF (not relevant really, but thought I'd disclose everything). Have a new sound. Thought it was belts, but stuck my head under the hood and it doesn't seem to be. I suspect an intake manifold gasket, but did a search and the previously mentioned symptoms don't seem to fit. It's a whistle that happens mostly when cold (actually been in the 20's here in Houston the last few mornings) is rev related, and seems to go away when warm. I have no idle or stalling problems. Any ideas? I'm waiting until 75k miles to do the timing belt, etc. I'm at 68k mile right now.

    I had a rattle under 40 degrees that seemed to go away when warm in my 1999. It was from condensation in fuel lines? I guess? A tank of dry gas and I haven't had it since.

    My point is that it could be something simple? The windshield gasket shrinkiing in the cold and causing a whistle? Maybe just a loose belt?
  • Could it be alternator noise? I had a car that would whine more noticeably when the alternator was heavily loaded such as when charging just after a cold start. Cars seem to do many spooky things when it's very cold, especially if you're paying close attention.
  • jimmyp1jimmyp1 Posts: 640
    gas, belts or electrical. Actually sounds like someone whistling fairly loudly further into the engine bay than the belts. Kinda underneath the big plastic cover, maybe to the driver's side a little. Thanks for the input. Any other thoughts?

    I am running the original Bridgestone 245/70R16 with 20K miles. Went to Discount Tire this weekend because the cupping was so noticeable and the tire noise was getting louder. He says there is not much you can do, other than cross rotate and hope it will wear down. Anyone know of a method to remove the cupped edge?
    I bought my Trooper 3 months ago, so I don't know how well they were rotated beforehand.
    FYI - Paid $14,500 for a loaded LS with 19k miles. Thought it was a pretty good deal. What do you think?

    What year and which color was it?
