#11795 of 11966 2002 Trooper Gas Mileage
Dec 13, 2008 (8:40 pm)
I have a 2002 Isuzu Trooper, and when winter hits, my mpg seems drops from 15 to 13 mpg. Does this seem normal? And, it's not much better on the highway. I also had one of Isuzu's reommended comprehensive tune-ups last year at around 50,000, and put on a new set of tires, and that did nothing to improve the mpg.
Any ideas on how to improve the efficiency in the winter?

Around Memphis I have noticed a drop of 1-2 MPH (real or imagined) when gas changed from Summer to Winter blend. Around here there was something added to make it burn cleaner...I'm thinking ethanol was added after the old (mtb?) was banned because it was harmful to the environment..
But now we have ethanol in our gas yearround causing that drop. Might want to make sure your tire pressure is around 35 psi or so.
BTW, I have a 2000 Trooper LS...my maximum mileage has been about 18.5 average is probably more like 17-17.5. Mixed light city and hwy. It would be difficult to get much better mileage than that IMHO unless you were on a flat road with no stops driving about 55 MPH.
I purchased a 2008 Saturn Outlook in August. Still driving the Trooper quite a bit to keep the miles down on the new one. It has a DIC with average mileage calculated. When I reset that reading, I can see how much drop there is in MPG just pulling up to a stop sign/light and then getting back up to speed. Also, a couple of minute warm-up idle will drop it pretty quick. (Remote start is great but not very effecient )

bsmart1, did you get Aisins hubs for your 99 Trooper.
I have a 2000 Trooper and also thinking of putting manual locking hubs.
#11799 of 11966 trooper mechanic needed in Costa Rica
Jan 01, 2009 (4:42 pm)
I have a '96 Trooper LS with the 3.2 liter gas engine. I am located in the Pacific Northwest near Tamarindo Costa Rica. I purchased this trooper in San Jose Costa Rica 6 years ago. The "freeze plugs finally rotted and pumped all the coolant out of the block. This overheated the engine, causing the heads to warp. I think it is time for a new mechanic and engine. The engine has almost 250,000 miles. Any one know a reliable mechanic and a place to purchase a "new" 3.2? I was also considering changing to a diesel motor, any ideas?
#11800 of 11966 trooper 3.5L lifter type noise after 300mi on short bk
Jan 05, 2009 (11:49 am)
Installed rebuilt short block and timing belt in my 2000 3.5L trooper and all came out great and motor ran smooth and quite and about 300 miles later I pulled my single axle trailer and lifter type noise starter and I have tried the following things. change the timing belt tensioner no help. sense noise on right side I changed lifters on rt. side and checked cam load springs and reset them and reinstalled no help. The oil pump was changed with short block and motor holding 80# above 2k and 40 idling. any suggestions before I start over?

So you did not change the lifters at the time you changed the block.....I suppose that would explain some of the valve noise, but I don't see how pulling a trailer would make a difference. Your oil pressure sounds real good, so I don't think it is oil pump or worn bearing surfaces, especially since the block is new. Since you also changed the tensioner, I would suspect lifters that haven't been changed???
One guys opinion. HTH
#11802 of 11966 turn signal&cruise control steering column switch
Jan 15, 2009 (3:45 pm)
Invested in a chilton interactive cd rom and it stated that turn signal and cruise control column switches are relative to each other. I noticed when I purchased my trooper that the cruise control column switch was loose and now even looser. But the real problem is the low/high beam headlights. Now when I use the turn signal switch the lights go off and on. the high beams don't click back in position and when I hold the lever back to keep the headlights on its only high beams. When I let go the low beams will stay on for a while or until I go down a real bumpy road. Could this be from the cruise control column switch becoming so loose? i was going to buy a turn signal column switch but could the cruise control column switch be the real culprit? do they keep each other in place inside the column box? I just want to be informed when I go to the mechanic since these are expensive parts and the steering column has to come off to fix it. By the way i love my trooper and would drive daylight only before I'd get rid of it.
#11803 of 11966 97 Trooper ABS / Battery idiots 16+Volt No Power Alt ?
Jan 18, 2009 (8:11 am)
Since my last posts in Summer of 2006, mileage has almost doubled from 135K to 265K, and now I'm an NHtrooper. Few more bruises and wear and tear, but still running strong with 16-19mpg. Timing belt blew around 190K, first garage in NH wanted to replace my engine, found a local AAMCO who offered to check it for free, drove away a couple days later for $475, been my shop ever since. Anyway, she's had a slight squeal that I've been ignoring, thinking PS belt, but all of a sudden I get the couple idiots, my voltage meter pegged, and little power, all while trying to get through 15" of fresh snow. Issue was sporadic and intensifying. Leaning towards an alternator problem, but found the positive terminal quite corroded, cleaned it up, hoping it hasn't traveled too far down the cable. Seems to be better and will try to make the 25 miles to my shop tomorrow. Am I on the right course, or should I be l looking in another direction, as well ?

Didn't get too far, will need a flatbed in the AM. The ABS and battery lights still pop up intermittently, but more of a concern is the lack of power in Drive, 3, and 2. Reverse, low, and neutral still function OK. Is this a tranny issue or bizarre connected electrical problem ? I've consistently serviced the tranny without any hint of problem earlier, just seems like they're related. Thanks for your consideration.
