Kia Optima

Mine does the same thing. I'm having my battery checked today. Someone told me that may be what the problem is.

Behind the exhaust manifold.

Put air in tires make sure air pressure is equal in all tires

The manufacture Recommends every 60K. You should at the very least inspect it every 60K and expect to replace the water pump at the same time. They will usually go out soon after the new belt is put on. If the belt breaks you will be buying a new engine or rebuilding your current one.

I am not sure what question you are asking, but if you are asking why you are always having to change the brake light on your Kia Optima...

I own a 2007 Kia Optima, and before that I owned a 2005 Kia Rio. In the YEAR that I owned the Rio, I changed the brake light four times. Since I have owned the Optima, about 18 months, I have changed the rear light 3 times and the headlight once. (actually, I never changed the lights. Jiffy Lube or Grease Monkey changed them for a nominal fee, usually around $5, because I don't think a rocket scientist with both an engineering degree and training from NASA could figure out how to change that high-riding son-of-a-bitch tail light.)

But I digress...

Hopefully that will answer both questions, because if you are asking what the procedure for changing the light is, obviously I have no idea, other than to advise you to take you car to Jiffy-Lube. Good Luck.

Just in case Kia has you roped into their "Customer's for Life" program, the Kia dealership will also happily replace any head or tail lights for you during your $45 oil change for around $20. No, I'm not kidding.

The gas tank on the 2008 Kia Optima holds 16.4 gal..

you gotta take off the interior piece on the ends of the backrest. at the bottom you'll find a 12mm bolt holding it on. you might have to take off the rear panel as well. 3 bolts on top, two on the bottom. use a spring compressor to remove the spring. you can rent one for free at some parts stores. get a haynes or chiltons!

directly below the the throttle body.

on a 01 optima its on the bottom of the transmission behind the drip pan (really).

likely the same on a 03.

its not surgery just take the fuel lines off the filter take loose the bolts. put the new one on make sure you look and see which one says in and out. it should be located a few inches away from the back tire.

Every 105,000 miles.

It is a bit of a hassle. The entire "package tray" must be removed. This means the the lower back seat must be removed to gain access to the side strips of the package tray that extend down towards the floor board. The whole thing lifts out with the speaker grills still attached. Most Optima's used 6.5" round speakers in the rear deck, some used 6" x 9". In July 2009 my local Best Buy automotive installation center charged $70. to swap in new speakers for my Optima. It took the pro about 20 minutes. Id allow 45 minutes to an hour if I attempted it. Good luck!

On the intake manifold near the firewall. AutoZone part number PCV1171. It is all steel construction, about 2 inches long, and screws into the manifold. The rubber hose that slips onto it needs to be changed as well if it is less than "like new".

Yes....120 amo

You mean the egr valve? Rios have precise timing with lower compression no need for an egr vale.

What you described sounds like alternator noise coming through the stereo. Make sure your stereo is properly grounded. (check for continuity between the vehicle chassis and the stero ground) You may have to install a noise filter to clear it. They are typically installed on either the power lead for the head unit, amp, or on the RCA lines feeding the amp (if you use one). Go to somewhere reputable like Crutchfield and search for "noise filter" and you'll see what I mean. Typically less than $20 and can make a huge difference.

It's more than likely your front brakes and the sound is reverberating thru the car look at the rotors on front and feel them and see if they are ruff and grooved if so you need to do a brake job as for the warning light that will not come on unless it's low on fluid or the abs senses a problem.

Depends what year. The 00-04 Optima/Sonata 2.4 liter 4 cylinder has 2 rubber timing belts and is what is called a "interference" engine. Anyway, the belts are the weak link and they fail at 70-100 thousand miles. To change them at 60,000 (recomended mileage) it will set you back 800.00. Now what car now days costs 800.00 for a 60,000 mile maintenence interval????????? Anyway if you dont, you have a paperweight with kia badges. So in an honest answer the Mazda with its Ford derived engines (both 2.5 and 3.0) is the way to go. The 05 Optimas and Sonatas have a chain like every other timing system in the world, which leads me to believe Kia and Hyundai learned their lesson through warranty concerns. Funny their engine warranty is at 60,000 ;)

The 2007 Kia Optima takes 24" drivers and 18" passenger side wiper blades. See sources and related links below for more information. Since there are over 22 different wiper arm attachments, do not buy wipers just by length only. Be sure to lookup exact wiper blade part numbers by vehicle make, model and year for the brand wiper you decide to purchase. This ensures correct length AND correct attachment.

In my late 2003 Optima it was in the trunk over the rear passenger wheel well.

You'll need a funnel but you pour it into the tube that holds the fluid check stick

Trouble code P0708 means:Transmission range sensor circuit high input
