Transmission leaked fluid excessively at 174000, required a rebuild.
Engine leaked oil excessively at 175000, had all seals and gaskets replaced.
Engine still uses a lot of oil.
Defrost setting of the ventilation system didn't work due to a disconnected cable.
Alternator failed at 182000.
Water pump failed at 191000.
Considering the age and high mileage of the truck, it holds up really well - in fact I am surprised that I didn't have more failures.
The engine could use more oomph at higher speeds and steep grades, but is more than adequate for everyday driving. Fuel economy was surprisingly good: 14..17 mpg city, 18..20 mpg highway.
The standard alternator is on the weak side: voltage drops noticeably when the engine idles.
Handling is good for a truck of this shape; however the seats lack lateral support in tight turns, and body lean can get scary at times.
Low-beam lighting range is too short for my taste.
Ride is bouncy and a bit too soft for my taste, but not excessively so, and the suspension and high ground clearance inspire confidence to tackle off-road terrain.
The stop-and-shift part time 4WD system is primitive, but effective.
Visibility is good, thanks to the huge windows. However, the side mirrors could be larger to reduce the blind spot.
I really appreciate the huge, boxy cargo space: with the backseat folded up, it is big enough to hold a fully assembled road bike, or lots of camping gear.
The design of the body shape doesn't appeal to everybody (and makes it sensitive to crosswind), but gives the truck a unique utilitarian look.
In summary I wouldn't call the '91 Montero an outstanding truck, but it is a solid performer with just the right blend of performance, utility and looks.
Bilstein Shocks did wonders for my `91 Montero because it does not lean in curves. Much better high wind stability. Gary Z.
Completely agree about the tiny side mirrors, they should be larger. Though I´ve seen quite a few Monteros with larger ones... Wonder why mine are so small :-/
My mirrors are huge!
My truck has 191,000 and is still running strong, I can't wait to put a twin turbo 3.0l mitsu engine it it.
My mitsubishi montero is a 1991 color black ls 4x4 all original 164000 miles and in exellent working conditions;
but since it has the original shocks, I just got me some gabriel. to replace them. and of course I love that square shape body.
