Isuzu Trooper



  • Getting ready to perform 60K service on my '01 LS 2WD, but I'm curious about a couple of things -

    1.) What is the "Extension" (2WD Only) and how can the oil level be checked?

    2.) "Scheduled Maintenance" says to check the power steering fluid every 7500 miles, while the "Severe Service" section recommends changing it every 30K. I've never had it changed. Is that really necessary or advisable?

  • I would go ahead and do the power steering fluid change if you have made it to 60K miles without trouble, be happy, change the fluid now so not to push your luck. The fluid gets dirty (sample some from the reservoir) from wear and high pressure hydraulic systems can run hot. I use the best power steering fluid I can find. Spend the time to read a half dozen bottles from different brands and with that decide on what's the best power steering fluid. Or call the technical help on oil web pages such as to discuss it with a human who makes their living knowing about oil.
    I had a 1984 Trooper, never changed the power steering fluid, at 160K miles the steering gear needed to be changed.
    On my 1995 when I had it, and on my 2001 I change out the power steering fluid every 30K.
    Changing the power steering fluid requires removing a hose.

    Sorry about your leak, I can't speak for 02, but 2000s don't have a fill tube.

    Worst case you have no fluid, and should specify a flat bed, best case, the leak is minimal, and you can drive it to a shop. can you approximate how much fluid is lost?

    if you crawl under, and have a look, you'll see whether or not there's a fill tube, or just a fill plug for the tranny.

    Since you'll be taking it to a shop for the tranny service,you might as well do a Drain and Refill on the TOD, it takes Tranny fluid also.

    have a great day
  • I got a problem hopefully one of you can help me out with, I got a 90 Trooper v6 and it starts up strong but as soon as it warms up it starts choking and dying then dies and wont restart til it cools down... no i would like to be able to drive the thing for more than 15 minutes so if someone has and idea what might be wrong i would love to know. I took off the cat thinking maybe it was clogged it has a small coulant leak but its always full when i take it out and it never over heats. so yeah help would be great.
  • I got a 88 Isuzu trooper 2 from my dad.It ran for a while then it started sputering when u push on the gas and then stalling.
    Then when u start it,and push on the gas to try to keep it running it would stall.Now it wont start at all.I replaced the filter and still nothing.When under the hood after trying to start,U dont smell any gas,I checked the fuel line and theres gas in it ??????
    Im lost !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
    HELP ME PLEASE !!!!!!!!!!!!!!!!!!!!!!!!!!!!!

    One place to start; Ensure the coolant temp sensor is working properly, it sounds as if it's not leaning out the richer cold start fuel air ratio once it warms up.

    Also, there is a possiblity that your injectors are terribly worn, and just spit too much fuel to idle a warm engine.

    (comments assuming you have fuel injection)I don't remember if those older GM v6s were throttle bodies with chokes or not, if so, you'd want to make sure the choke opened once warm.

  • Was the 88 Trooper sitting a long time? I suspect a gummed up carburator. If you are good at taking things apart, cleaning and getting them to work again, take the carb apart, clean out every bit of it, look for clogged pinholes, stuck float etc..
    Also, change the fuel filter and perhaps the fuel in the tank should be drained and replaced. There might also be a filter inside the tank that could be clogged.
    Please post what you find.
  • Yes it was sitting for 3 years.And there's no gas getting to the carb.I have changed the fuel filter already.I'll try dainning the gas tank then i'm going to replace the pressure regulator then fuel pump. Does that sound right ?

    You can use "turkey buster" method. Not from you kitchen, buy your own. Just suck old fluid from reservoir and refill, drive couple hundred miles and repeat, no hose disconnect required. I use atf in ps.
  • I just bought a 2002 LS w/ an automatic that doesn't seem to want to stay in overdrive on the interstate. Before I take it in to use the factory warranty (i hope anyway), are there any suggestions I can try? I've played around with the winter mode and sport mode, doesn't help. thanks
  • How many miles on your Troop? When was the ATF last changed? Old (more than 50K) worn fluid can cause a host of shifting problems. It's also possible that the Mode Sensor switch is faulty. If so, a good cleaning might well cure the problem. Run a search on this board and you'll find a lot of directly related info.

    Will it stay in O/D at say 50-60 mph but just not say 65 mph or higher? I have a 2000 LS Trooper (only came in LS with Auto that I know of. Only time my will not go into O/D is the first couple of miles. Once the tranny is warmed up it will go into O/D okay. Never had a problem on the interstate. You might try disconnecting the power for 5-10 minutes from the battery. Just in case the computer has stored some weird code that is causing the behavior, this 'might' clear it out. BTW, mine is 2 wheel drive. Is you Trooper 2 or 4 Wheel drive? If 4 wheel drive, do you have TOD on or off? Just curious.

    BTW, If I recall correctly, the 120,000 mile, 120 month powertrain warranty was only for the original purchaser and could only be transferred to a family member. If the Trooper was sold/transferred to anyone else, then the basic warranty was 36 months/50 or 60,000 miles.
  • 36k thats why I can't understand the problem? No leaks, not that you can check the tranny oil level! Thanks for the help just the same.
  • No to any speed with the O/D, its 2wd and in cherry shape. I had a friend ask me if they were still making them, he thought it was new. I'm thinking that it hasn't been driven enough to keep it working smoothly. Before I try the warranty i'll take it for a long interstate drive and see if that cures the problem. Thanks as well for the help.
  • With only 36K on the Odo, power flush the tranny fluid! "Drain n' Fill won't to it. 36K is about when my tranny problems started. I did the D&F at 30K, and it solved nothing. F&F'd at 47K, and life is good again. Do it, and be happy.

    Here's another flush/don't flush post:

    Mileage seems to be a factor in the flushing debate.

    I understand that the 2nd Gen trooper has a GM tranny in it.

    is it feasible to get a salvage yard Transmission fill tube, from an equivilant GM vehicle and adapt it to our troopers?

    I wouldn't mind climbing under to pull the drain plug, but would like the convinence of checking and filling from the top if such a proposition was feasible.

    What other GM vehicles was this tranny used in?

    Thanks in advance

    Never mind, I Found a post that listed them by name

  • 1996 trooper :mad:
    Okay, the 4 wheel drive light keeps flashing while driving. It's not in 4wd though. The trooper quit the other day and i had a tow truck bring it home. The starter died so i replaced that and now that i can drive again, the light keeps flashing. Any suggestions?

    OK. I've got a silly one.
    I thought it would be a snap to change a headlamp on my '99. But after monkeying with it for a while, I couldn't remember if it twists loose or just pops straight out - either way I couldn't get it! Is there a trick or am I just that much of a weenie?!?
