The turbo diesel in your Isuzu Trooper is perred by some drivers because of the fuel economy. If you are having problems with the turbo diesel engine, there are a few things that you can do before you take it in for service. You can check common issues yourself with little hassle.

Instructions

1

Turn the key in your Troopers ignition to engage the instrument panel. Make a note of the fuel gauges level. If you dont have enough gas to start the Trooper, fill the tank up with gas and then try to start the vehicle.

2

Replace the fuel with the proper kind of diesel. Summer diesel can get cloudy in winter months. This can cause the fuel filter to clog.

3

Raise the Trooper with a jack to check the starter. Have a friend turn the ignition and listen for the starter to buzz. The starter is the small black box next to the engine. If the starter buzzes or clicks, you need to have it replaced by a service technician.

4

Look at the bottom of your Trooper for any fuel or liquid leaks. Have any leaks checked by a certified mechanic.

5

Use a voltmeter to test the battery. Check the battery sticker to get the volt rating. Most diesel engines use a 6.5 V battery. Connect the leads from the voltmeter to the battery terminals on the top of the battery. If you dont get the 6.5 V reading, have the battery replaced or jump the car.

Isuzu introduced the Rodeo SUV in 1990 as a 1991 model and continued selling it until phasing it out in 2004 and replacing it with the Ascender. Isuzu updated and revised the Rodeo several times during the vehicles tenure, and the smaller, two-door Rodeo Sport was available from 1998 to 2003. The torque specs for the Rodeos lug nuts varied from year to year, but in most years all trims shared the same lug-nut specs.

General Torque Information

Torque is the amount of force applied to twist or turn an object at its center. Torque specs are usually given as foot-pounds or inch-pounds, with one foot-pound equaling the force of one pound applied at the end of a foot-long lever to turn an object. It is important to make sure that the threads of the bolt and the lug nut are clean before tightening the lug nuts, as an dirt or build-up on the threads can cause increased fiction and affect the amount of torque needed to properly tighten the bolts. It is common to lightly lubricate a bolt or lug nut with clean motor oil before tightening it. Most mechanics recommend using a torque wrench when tightening bolts, as it is nearly impossible to accurately gauge torque by hand.

The 1991 to 1995 Isuzu Rodeo

For all trims of the 1991 to 1995 Isuzu Rodeo, except for those with aluminum wheels, tighten the lug nuts to 66 foot-pounds of torque. For those with aluminum wheels, tighten the lug nuts to 87 foot-pounds of torque.

The 1996 to 1997 Isuzu Rodeo

The torque specs for the lug nuts were the same for all trims of the 1996 to 1997 Isuzu Rodeo. The lug nuts should be tightened to 66 foot-pounds of torque.

The 1998 to 2004 Isuzu Rodeo and the 1998 to 2003 Rodeo Sport

The torque specs were the same for all trims of the 1998 to 2004 Isuzu Rodeo and the 1998 to 2003 Isuzu Rodeo Sport. The lug nuts should be tightened to 87 foot-pounds.
