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.

Item as described quick delivery

Kia published one set of specifications and torque sequences for the 2003 Optima, and this factory service and repair manual is matched to that exact year, engine and trim — so the figure you are working from is the one written for your car, not an approximation carried over from a neighboring model year.

Engines covered

  • 2.4L inline-four — DOHC, naturally aspirated, gasoline
  • 2.7L V6 — DOHC, naturally aspirated, gasoline

Body styles covered

  • 4-door sedan

Trims covered

  • LX
  • SE

Known issues on the 2003 Optima. Two recalls are on federal record for this model year. The first covers the front suspension: corrosion of the front subframe could lead to separation, possibly resulting in a vehicle crash — a recall Kia issued for 36,538 model year 2001-2004 Optima vehicles. The second covers the fuel tank assembly, which may contain a valve that does not close properly; if the vehicle were to roll over, fuel spillage in the presence of an ignition source could result in a fire. Owners have filed 190 complaints for the year and Kia has issued 21 technical service bulletins. The factory diagnostic and repair procedures behind each of those systems are here.

Whether you are inspecting the front subframe for corrosion, checking the fuel tank assembly valve, or working through a routine service interval, it keeps you on the OEM procedure and the correct specification for your specific 2003 Optima.

NHTSA #04V18000012/04/2004Component: FUEL SYSTEM, GASOLINE:STORAGE:TANK ASSEMBLY
