2004 Isuzu Npr

Component

Fuel System, Diesel:Storage:Tank Assembly

Consequence of Defect

on certain trucks equipped with rpo ik9, due to insufficient durability and testing, the fuel switching manifold solenoids lack water or salt intrusion resistance, which can lead to failure of one or more solenoids. fuel switching manifold solenoid failure will cause incorrect fuel delivery resulting in fuel overflow from the fuel filler neck.

Corrective Action

overflow fuel may result in high amount of diesel fuel leakage. fuel leakage, in the presence of an ignition source, could result in a fire.

Recall Notes

dealers will replace the solenoid valve assembly with an improved assembly including additional detection circuit and enhanced water resistance free of charge. the recall began on october 27, 2005. owners may contact isuzu at 1-800-255-6727.

1998 Isuzu Npr

Component

Steering:Gear Box (Other Than Rack And Pinion)

Consequence of Defect

vehicle description: truck chassis. the intermediate steering shaft-to-steering bolt was not tightened properly during assembly. this can cause steering noise, loose steering, and an uncentered steering wheel.

Corrective Action

loss of steering could result.

Recall Notes

dealers will inspect the steering shaft and retighten to the specified torque.

1997 Isuzu Npr

Component

Service Brakes, Hydraulic:Foundation Components:Hoses, Lines/Piping, And Fittings

Consequence of Defect

the front axle brake hoses were damaged during transportation of the front axle assembly with the brake hoses attached.

Corrective Action

this damage could result in brake fluid leakage, reducing the braking effectiveness and increasing the stopping distances.

Recall Notes

dealers will inspect the front axle brake hoses (right and left) and any hose showing damage will be replaced.

1994 Isuzu Npr

Component

Service Brakes, Hydraulic:Foundation Components:Hoses, Lines/Piping, And Fittings

Consequence of Defect

on some vehicles, the sealing surfaces for a hydraulic brake hose on a front brake caliper were covered by paint residue. brake fluid gradually dissolves the paint, opening a small path between the sealing surface and the gasket allowing brake fluid to leak when the brake is applied.

Corrective Action

this can result in increased stopping distances and a possible vehicle accident.

Recall Notes

dealers will remove paint from the brake caliper, replace copper gaskets and bleed the front brakes.

1990 Isuzu Npr

Component

Engine And Engine Cooling:Cooling System:Fan

Consequence of Defect

at high engine speeds, the cooling fan adapter plate, which connects the cooling fan and the fan pulley, has insufficient strength, allowing cracks to develop in the adapter plate.

Corrective Action

cooling fan could be dislodged, damaging radiator and fan guide; and fan could break loose, fly out of engine compartment, and injure persons in the immediate vicinity.

Recall Notes

repair or replace adapter plate to prevent cracks and damage.

1989 Isuzu Npr

Component

Engine And Engine Cooling:Cooling System:Fan

Consequence of Defect

at high engine speeds, the cooling fan adapter plate, which connects the cooling fan and the fan pulley, has insufficient strength, allowing cracks to develop in the adapter plate.

Corrective Action

cooling fan could be dislodged, damaging radiator and fan guide; and fan could break loose, fly out of engine compartment, and injure persons in the immediate vicinity.

Recall Notes

repair or replace adapter plate to prevent cracks and damage.
