1988 Isuzu Trooper II

In 1986, Isuzu introduced the 4ZD1 four-cylinder 112 PS

(82 kW; 110 hp) 2.3-liter engine, regarded as a considerable

improvement over the previous gasoline engines because of

its higher power, Kevlar timing belt replacing the chain driven

ones in the 1.8l and 2.0l engines and improved and larger

two-barrel carburetor. This engine eventually proved

somewhat problematic with a plethora of burned valve

problems because of the poor coolant flow design of the

overhead cam/valve head with mechanical lifters.[citation needed ] A later head casting improvement by an

Italian firm corrected this problem through improved coolant

flow. Also available only for 1986 in the US was the 87 PS

(64 kW) 2.2l C223T turbocharged diesel engine. It was not a

popular option because of the low power generated. The

C223T engine had a Garrett turbocharger and it actually

performed admirably for its small size and ironically seems to

be the more dependable of the two engines offered that year

because of its simplistic design and robust bottom end.

Because of those problems, Isuzu changed the 4ZD1 for 1987and used the standard 2.8L GM V6 for 1987 until their own

new V6 engines could be manufactured.

In 1987, Isuzu

introduced a 120 hp

(89 kW) 2.6-liter

(4ZE1) I-TEC

fuel-injected engine

for the US market. An

optional General

Motors 2.8-literpushrod V6 borrowed from the Chevrolet S-10 pickup was also

available. Manual transmission equipped models had a gear driven transfer case with a 2.28:1 low range ratio;

models equipped with the 2.6-liter four-cylinder engine and automatic transmission had a 2.66:1 low range

transfer case. Later first-generation models offered an optional four-speed automatic transmission. Models from

1988 to 1991 were equipped with live rear axles and four-wheel disc brakes. Also new in 1987 were rectangular

headlights.

Overseas model engines included the Isuzu C223 (2,238 cc), C223T (a turbocharged version of the same) and in

the late 80s naturally aspirated and turbocharged 2.8 L 4JB1 diesel versions, all straight-four engines. The

turbocharged 2.8 originally produced 95 PS (70 kW), not much more than the 87 PS (64 kW) of the

considerably smaller C223T due to new stricter emissions standards. Later versions with intercoolers fitted

offered as much as 115 PS (85 kW).[1]

In 1989 only, a short-wheelbase (90-inch) Isuzu Trooper was imported to the US market as the Trooper. All of

these short wheelbase Troopers were equipped with 2.6-liter fuel-injected inline-four engines, 4.77:1 differential

gears and 15×7-inch aluminium alloy "snowflake" pattern wheels. Automatic and manual transmissions were

offered.

In Central America, Troopers were offered with removable roofs and a higher wheel clearance. Powertrain

options included the Isuzu 2.8-liter turbo diesel.

Second generation (1991–2005)

In 1991 for the 1992 model year, Isuzu completely redesigned

the Trooper to keep pace with changes in the SUV

marketplace, making it larger, more powerful, and more

luxurious. These 5,500 lb (2,500 kg). vehicles used a 3.2 L

single overhead cam 177 PS (130 kW; 175 hp) (SOHC) petrol

engine, with an available 3.2 L dual overhead cam (DOHC)

version rated at 193 PS (142 kW; 190 hp). A SOHC 3.2 L

engine producing 193 PS (142 kW; 190 hp) was introduced in

1996, replacing the prior engines. Most models still used a

part-time four-wheel-drive system, which required stopping

the vehicle to engage and disengage the front axle. Starting

with the 1996 SE Limited Troopers came with shift on the fly

engagement.

From 1992, the UBS

Jackaroo", as it isknown in Australia)

only coupled to a

part-time 4wd system

with open front and

limited slip rear

differentials. The

2.283:1 low range can

be selected on the

move, providing the front hubs are engaged, at up to 15 km/h 1st gear,

25 km/h 2nd gear and 40 km/h 3rd to 5th gears. (The 3.2-litre V6 petrol engine version was also available with

an optional four-speed auto and auto locking front hubs.) The same diesel engine was also available in the U.K.

and other markets with a belt-driven overhead camshaft, which developed slightly more power. After 1998, and

the introduction of the 4JX1 3.0-litre diesel engine, a four-speed automatic transmission was made available in

addition to the five-speed manual transmission.

During this period, Isuzu and Honda had a working arrangement[4]

that allowed Honda to sell a rebadgedTrooper. In Japan it was known as the Honda Horizon from 1994 to 1999, and as the Acura SLX in the United

States from 1996 to 1999.

Beginning in 1998, Troopers in the US were equipped with a DOHC 3.5 L engine producing 215 hp (160 kW;

218 PS). European and Asian buyers could opt for the diesel engine option of the 4JG2 3.1 L (later superseded

by the more problematic 4JX1 3.0 L of 159 PS/117 kW). A Borg-Warner torque-on-demand all-wheel-drive

system was introduced, along with freshened styling. The grille was redesigned again for the 2000 model year.

Transmission options included a five-speed manual transmission, the Aisin AR5 [5] and the electronically

controlled 4L30E four-speed automatic. The 4l30E was fitted with both a "power" shift feature allowing the

gearbox to take better advantage of the engine's power by adjusting the shifting nature and a "winter" modepermitting third gear starts for added stability in slippery conditions.[6] The 2000 to 2002 Trooper included a

feature called "Grade Logic" which allowed the transmission to automatically downshift on steep grades in order

to slow the vehicle down.

The suspension consisted of a fully independent torsion bar front suspension, and a multilink coil sprung rear

suspension integrated with a solid rear axle.

The Trooper LS and S models offered 117.8 cu ft (3,340 L) cargo space, while Limited models had 112.3 cu ft

(3,180 L).

While US-spec Troopers came only in the 5-seat models, in Europe and the UK 7-seater version was alsooffered. Optional on all models was a rear limited slip differential. In the US the 3-door RS model was sold only

from 1993 to 1995.

In 2002, the Trooper was discontinued in the United States in favor of the smaller Axiom and the larger

GM-produced Isuzu Ascender, a re-badged GMC Envoy.

A Trooper with the 16-valve 159 PS (117 kW; 157 hp) 3.0-liter 4JX1-TC engine was sold in the Philippines

from 2002 until model year 2005. Known as the Skyroof Edition, it came in a rear-wheel-drive configuration

with anti-lock brakes, a limited slip differential, billet-type radiator grille, and large power moonroof. Other

questioned by Isuzu were false, with one displaying "reckless disregard" for the truth on the part of Consumer

Reports magazine, but that Isuzu was not damaged by that statement.[11][12] Two of the 10 jurors on the panel

did not believe the magazine believed that the other seven statements were untruthful when they published

them.[11] Consequently, the full jury panel did not award Isuzu monetary damages for the alleged damage to its

reputation and lost sales.[11] Isuzu calculates the total cost of the Consumer Reports claims at $244 million.[13]

As Isuzu was denied damages on all counts, the formal court judgement in favor of Consumers Union entered by

Paez required Isuzu to pay CU's "reasonable costs" of defending itself against the suit, not including attorney's

fees.[14]
