Isuzu Trooper



  • I have a 93 Trooper with the same ticking sound. (Pushing close to 190,000 mile on the baby).

    Actually there are two sounds I get - one is the engine itself which has been there pretty well for some time. The other seems to be associated with the timing chain. I've come to notice that the timing chain tends to rattle more when the oil is low (pressure still OK though).
  • I am having the EXACT SAME ISSUES with my 1998 trooper right down to the switching back and forth from the fresh and recirculated air will sometimes bring it back to life. I already changed the voltage regulator and it seemed to help for about 3 months. The blower motor seems OK when removed and plugged into 12 VDC.
    Were you able to fix your problem? If so could you detail how you fixed it for us?
    Thanks a lot.
  • atfdmike:

    I determined that the problem with my heater blower was the resistor controller (don't know what this piece is called). By examining it, I figured out which were the "bypass the resistors connectors" were in the plug, and I jumpered it with a piece of solid 14 guage wire. When I turn the fan switch to high, it blows like stink.

    The resistor controller unit is held into the air duct with two screws, just "downwind" of the fan, right behind the glovebox. Take out the glovebox (four screws) and you on it.

    Now, to find an Isuzu dealer that actually has the part...

    Thanks for your help with the wiring diagrams and the concepts.
  • can any body tell me what xs means,i think it has something to do with the transmission.does anybody elses trooper have two buttons by the automatic shifter that says power and winter drive. thanx

    Hi, Sounds like you worked it out. Good luck finding part, but maybe you can adapt a different model if you can't find the exact match.

    The Trooper you have has the options to increase traction on slippery surface by starting and staying in 3rd gear. That is your winter drive. Usually the instructions were on the driver's visor. I believe you can just hit the button while driving to turn it off and the next time you stop, it should be back to normal. The Power switch changes the shift points of the trans so that it will keep the torque curve in the optimum band. I have only known it to be used for towing a load.
    I am not sure what the "xs" you refer to is about. Hope this helps.
  • I'v been burning oil @ a quart every 1000 miles. Is there reason to be concerned? Thanks.
  • Can you provide some instructions on cleaning the EGR valve? I'm not that familiar with it. Also how do you replace the PCV valve? Thanks for any assistance. BTW...I have an '00 Trooper LS, 2X4.
  • I've been tracking the closing prices on EBAY for Troopers and using a very simple linear regression (straight line) of the data I've taken (n=63), with a relationship of miles to price, I'd say a fair price is $5,390. This does not take into relationship age, condition, appointments, etc. It simply compares miles to closing price on EBAY (for those auctions that met or exceeded the reserve price). The equation for those interested is y= -0.0161+6975.

    cool equation,
    Now, automate your algorithm and create a web page, with ads for all sorts of stuff to buy.
    Next, offer the technology as a service for market research

    Don't you need one or more independent variables on the right side? :)

  • The part wasn't bad at all... $42 from the dealer.

    Thanks again.
  • I had a trusted mechanic tell me that that codes say that my MAF is bad at 80K (the CEL was on). The OEM MAFs are about $500.

    I found an *aftermarket* MAF for $155... any chance it will actually work?

    Anyone else interested, send me an e-mail and I'll send you the link.
  • There's an FAQ here on cleaning the EGR port/tube:

    If that link doesn't come through (CarSpace might not like it), e-mail me.
  • I have a 1995 Trooper 4 x 4 that I have had for a little over a year. I just noticed, first by smell, that the drivers side floor board is very wet. Looks like it soaked from the floor board up instead of floor mat down. Anyone have any ideas? Could it be something like the A/C ?

  • Could be a leaky windshield seal, have you changed the windshield lately?
    I would clean out the vents below the wipers on the hood and make sure nothing is blocking the areas around under the hood near the firewall.
    I enjoyed a 1995 Trooper for 140K+ miles before it was rear ended so hard the air bags went off and that $6000 air bag repair totaled it.
  • The A/C coil is right there, behind the glove box. The fan motor is to the right(turn it on and you'll hear it) the A/C coil is housed closer to the transmission hump. It's pretty easy to get the glove box off (two screws at the bottom hold the hinges to the dashboard frame) so you can get a better look. There is an line for draining the condensation out through the firewall, and, if it's plugged, you could get a leak like that.
  • look at the section for the EGR valve...should be links to instructions and pictures here. Also, look for the PCV valve section. There is a good diagram there that shows the location (driver side of engine). A new PCV valve was maybe $3 at AutoZone if I remember correctly, so I just replaced mine even though the old one looked and sounded okay.
  • I am looking to buy a 2002 Trooper. I am trying to find out if there major problems with this vehicle. From reading all the reviews the only thing I seem to run across is possible excessive oil usage. Any other possible problems? Like transmissions? Thanks!
  • I like to keep things simple so less stuff to break, I occasionally drive my Trooper very hard, and I like the tight coupling of a clutch vs torque I have always bought manual transmission Troopers. More fun less to break. However, the later year Troopers with automatic have TOD which manages 4wd so that you can drive 4wd on patchy ice roads, a feature which I think is really nice.
    I have had 1984 Trooper 201K miles, 1995 Trooper 140K miles, then rear ended, totaled even though it was still drive able. Now I have a 2001, very nice one previous owner who took great care. I have no troubles with it except that I should keep it cleaner than I do.
