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

More detailed than I thought, still trying to navigate through it, not what I thought it would be, thought it would be more like the Haynes manual.

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.

Every torque figure, clearance and service specification in this manual is tied to the 1990 Lexus LS 400 as Lexus built it that year, right down to the 4.0L V8 (1UZ-FE) and the Base trim, rather than a close-enough number carried over from an adjacent model year.

Engines

  • 4.0L V8 GAS Naturally Aspirated

Trims

  • Base

Known issues on the 1990 LS 400. One recall is on federal record for this model year, filed under exterior lighting and the brake light switch: the lamp housing of the center high mounted stop lamp could become distorted after prolonged illumination, particularly under high temperatures. Owners have filed 24 complaints for the year, and Lexus has issued no technical service bulletins for it. The diagnostic and repair procedures behind that exterior lighting system are here.

Whether you are chasing a stop-lamp fault, servicing the 4.0L V8, or following a scheduled maintenance interval, it keeps you on the OEM procedure and the correct specification for this 1990 LS 400.

NHTSA #89V21200004/12/1989Component: EXTERIOR LIGHTING:BRAKE LIGHTS:SWITCH

LAMP HOUSING OF CENTER HIGH MOUNTED STOP LAMP COULD BECOME DISTORTED AFTER PROLONGED ILLUMINATION, PARTICULARLY UNDER HIGH TEMPERATURES.

Remedy

REPLACE LAMP HOUSING WITH ONE OF HIGHER TEMPERATURE RESISTANT MATERIAL.

MY CAR, MADE BY TOYOTA, HAS ALL THE SAME PROBLEMS, FAULTY PARTS, AS THE CARS THAT WERE RECALLED FOR SUDDEN ACCELERATION. I HAVE HAD THE SUDDEN ACCELERATION PROBLEM HAPPEN TWICE AND I AM CURRENTLY UNABLE TO DRIVE THE CAR BECAUSE OF A FAULTY RESISTOR THAT CONTROLS THE FUEL FEED TOT THE FUEL PUMP KEEPS CAUSING THE CAR TO ACT LIKE IT IS RUNNING OUT OF GAS. VERY DANGEROUS. LEXUS HAS REFUSED TO FIX IT EVEN THOUGH I AM WILLING TO PAY. THEY WANT NOTHING TO DO WITH CARS WITH THE SAME PARTS AS SUDDEN

09/16/2015Component: VEHICLE SPEED CONTROL

IN APPROXIMATELY 1995, I EXPERIENCED THE "SUDDEN ACCELERATION" PROBLEM TWICE WITH MY LEXUS LS. AT THE TIME, NO ONE HAD EVER HEARD OF IT AND THE DEALER SAID HE COULD NOT REPRODUCE IT AND COULD DO NOTHING. AFTER THAT I WAS MORE CAREFUL WITH THE FLOOR MATS AND THOUGHT I HAD SOLVED THE PROBLEM. FOR THE LAST 7 TO 8 YEARS, THE CAR SUDDENLY SLOWS AND STALLS. I HAVE REPEATEDLY COMPLAINED TO NEW COUNTRY LEXUS BUT THEY JUST SAY THAT THEY CANNOT REPRODUCE THE PROBLEM AND DON'T KNOW WHAT IT IS.
