The download I received was a complete waste of my money. Was not even close to what it was represented as. I thought I was getting a proper service repair manual. What I got was a collection of service bulletins. I sent an email to your company right after I looked through it requesting my money back. Have yet to hear a response. Terry Muich

It was much larger than i expected. 5 documents at 12k pages each. Its not something ill actually be able read but its easy enough to find what you need..
The Ford F250 manual is much easier to navigate at just over 8000 pages.
If i spend the money for Adobe Acrobat Professional ill be able to break it down into manageable bits.
Both manuals area great value for the money.

Schematics were not high resolution making the markings and names difficult to read when zoomed in. Improvement is needed. Otherwise it is a good document.

I wasn’t sure why I needed this to be a PDF, but it was apparent once I got it. It includes what would be thousands of pages if it were in print. The links take you to wherever you need to go in the text.

would rather have a maintenance manual. have a parts manual from parts vu company. only difference is that your parts manual has all together whereas the parts vu had to download the differsections individually.

Our original order was supposed to be for our 2014 Subaru Outback, yet the manual came up as Forester. We did have to purchase a new manual in order for them to send us the correct manual. We hope it will help us repair our Subaru.

Fitment is what makes this one worth having open on the bench: the 1998 Lexus GS 400 service and repair manual is tied to this exact model year and to the 4.0L V8 (1UZ-FE) fitted to the Base car, so the clearances, torque values and diagnostic trees you work from are the ones Lexus published for it rather than figures carried over from an adjacent year or a different engine.

Engines

  • 4.0L V8 GAS Naturally Aspirated

Trims

  • Base

Known issues on the 1998 GS 400. One recall is on federal record for this model year, and it concerns the vehicle stability control system: a manufacturing defect in the yaw rate sensor can let the VSC operate improperly if the sensor is affected by certain electromagnetic waves, such as those from a cellular phone, and should that occur the brake may operate unexpectedly, affecting steering and speed control and increasing the risk of a vehicle crash. Owners have filed 32 complaints for the year, and no technical service bulletins are on record. The diagnostic and repair procedures behind that system are here.

Whether you are tracing a stability control fault back to the yaw rate sensor or working through a scheduled service on the V8, it keeps you on the OEM procedure and the specification Lexus wrote for the 1998 GS 400.

NHTSA #98V08000017/04/1998Component: ELECTRONIC STABILITY CONTROL:AUTOMATIC (ASC)

VEHICLE DESCRIPTION: PASSENGER VEHICLES. DUE TO A MANUFACTURING DEFECT OF THE YAW RATE SENSOR FOR THE VEHICLE STABILITY CONTROL (VSC), THE VSC CAN OPERATE IMPROPERLY IF THE SENSOR IS AFFECTED BY CERTAIN ELECTROMAGNETIC WAVES, SUCH AS FROM A CELLULAR PHONE.

Consequence

SHOULD THIS OCCUR, THE BRAKE MAY OPERATE UNEXPECTEDLY, AFFECTING STEERING AND SPEED CONTROL, INCREASING THE RISK OF A VEHICLE CRASH.

Remedy

DEALERS WILL REPLACE THE YAW RATE SENSOR.
