Lexus LS

no it will still run. just a little ruff. someone did not set the time marks right. i would reline all timinng marks on the gears

left side panel on drivers side. Where you put your feet. pull the carpet back and there it is

its not a job for a backyard mechanic (no disrespect) it is located under the intake manifold and is a job and a half if not familiar with the lex v8. i would check battery cable connections and grounds also make sure start signal is going to starter solenoid. a bad alarm,or neutral softy switch. i have 300.000 miles on my ls400 1990 a starter is still cranking. you can also have someone hold the key in the start position wile you tap the starter with a long 3/8 wratchet extension. my bet is a bad connection power or ground also try to start it in neutral instead of park this will check a faulty saftey switch. also all aluminum engines tend to develop bad connections more then a iron block

The 3.3 L V6, 4.7 L & 4.8 L V8 all have a timing belt that must be replaced every 90,000 miles.

The cost of a Lexus bulb replacement varies slightly by the model of the car and the retailer. On average the bulbs cost between 7.50 and 15.50.

ive seen cars with 350,000+ miles

On cars from about 1980 to 1996 they have ON BOARD DIAGNOISTICS 1 which is not as effocoent as OBD11. I am not sure how you get the codes from the OBD1 on this perticular car other than a scanner which auto zone will read for free. On the American cars you ground the "A" and"B" terminals in the ALDL connector and count the flashes of the check engine light.

Mounted on top and inside the fuel tank.

Go to lexusownersclub.com, its really informative, also check out lexls.com/tutorials this site gives instructions with pictures, really helpful!

Console needs to come out. It is a 2 piece unit held in by 6 Phillips head bolts, 3 per side, on the side. Rear lifts out first, then the front over the shift knob, which I take out but you don't have to. Four more Phillips head bolts hold the plastic indicator to the chassis; take those out, flip the indicator over then twist out the bad bulb. A 193 or some such -- auto parts store can tell you the right one.

just pull up on it from fuse box, if need be, be very carefull and use pliers to re move it.

yes u can the lexus has a big brakes in the front so u will need to shave them down or use spacers and u need a 22/8 rim or 22\8.5 inch with a 225/30/22 tire or a 235/30/22 tire and u will be good

I successfully pryed off the Grill of the Tweeter a few days ago. I am not sure how to get the tweeter out. I did notice it was angled once I got the grill off. Use a flat screwdriver covered with cloth (so you dont scratch the dash), and there is a clip on the about 5'oclock position for the Lleft speaker and 7 o'clock position for the Right Speaker that you can pry up on to get the grill off. You probably blew the speaker in the door panel anyway.It has much more movement and is more likely to tear on the foam suspension ring. I took off the door panel and using some cloth spray adhesive i reglued the speaker and now it works fine! good luck

The traction control systems seem to develop problems at this age. Look on lexusownersclub.com in the LS400/430 forum and post a question. I get most of my Lexus repair answers from this board. Also check on lextreme.com as he offers several tutorials. . VBDENNY

For a second generation IS250: Hold down the the odometer reset button and press the start engine (without your foot on the brake to prevent from starting) to switch to the acc. mode, continue holding the reset button for about 5 sec until the visual countdown ended et voila, your system has been reset.

The cost for the parts for a major tune-up would run approximately $270-350, depending on the quality/brand. One of the biggest differentials is the cost of the spark plugs. For example, top of the line iridium plugs by Denso or NGK run close to $12 a piece (at an auto parts store, not the Lexus dealership which would be much higher); while the standard spark plugs are about $2 a piece. A typical major tune-up (if you're going to do it yourself) includes the spark plugs, distributor caps, rotors (the LS400 is unique in that it has two distributors, so it needs two caps and two rotors), air filter, oil filter, fuel filter, PCV valve, PCV valve grommet, and ignition wires. Labor is not included in the above price estimate; this is assuming you'll be doing the work yourself.

Here's the system block diagram: the pump, the hoses and the powersteering ram. It's a closed system. The fluid in there stays in there unless there is a leak. The pump pressurizes the system via power derived from the belt that drives it. A hose and line delivers the fluid to the ram. In the ram, the fluid forces the operating cylinder one way or the other, as directed by the steering wheel. Fluid returns to the pump via another hose and line assembly.

If you are adding fluid, it is getting out of the system. You are looking for a leak. Internal leaks in the pump or the ram will cause the system to work poorly, but won't necessarily cause a loss of fluid. If you are replacing fluid, it's getting out. Look at the fittings and the hoses and the ram itself. Fluid can leak at fittings, out of hoses, or out of the seals in the ram, and that means out along the operating shaft, so look there.

It may help to put a clean piece of cardboard under the car to help spot the leak. Use a large enough piece of the stuff so it is under the pump and the ram and the rest of the delivery system. (Newspaper may not stay put.) Start the car in a safe way and in a safe place, and then just turn the wheel back and forth slowly while sitting there in park or neutral so you don't go anywhere. After a minute or so, shut the car off and have a look at your cardboard. Go for another minute or two if you don't see anything. If you have a leak, it should show up shortly. You may have to clean some or all your hoses and fittings off to find a small one, but with some luck you'll have it spotted in a few minutes.

I have a first gen. LS400 myself, and here might be a simple fix that could save you alot of money.

Does your car blow a little (or a lot) of white smoke when you start it up cold (first time you start it for the day)?

If the answer is yes, your problem is most likely the exact issue mine had; which is also an extremely common issue with the first generation LS400. It is called an air control valve, and when it fails it will cause power steering fluid to be sucked into the intake on start up which creates your powering steering "leak" (Which can be alot of fluid!), and also could account for other problems such as a failing alternator or starter... If any of this rings true read the following taken from clublexus.com where you will find everything you need to know about this issue. Very simple cheap fix.

---------------------------ClubLexus forum post below---------------------------------

The most logical thing to check would be the air control valve. If this valve is leaking, there are no visible signs of fluid because it is being drawn into the engine and burned. A good clue for this being the problem is a white puff of smoke from the exhaust when you crank the car. However, if the volume of fluid being leaked is small, this would not necessarily occur.

Yes, your mechanic can easily remove the air control valve. It screws into the bottom of the power steering pump.

You can check for leakage in this valve by detaching the two hoses that run from the valve at the nipples where they attach to the air intake and manifold. Seal off the ends of the hoses by putting a screw or something similar into them. You would also need to seal off the two points where they attach to the air intake and engine. You will not do any harm by trying this for a few days. You might not even notice a difference in the car's operation.

If the power steering fluid loss stops while you have these hoses disconnected, you have found your problem. The part number for the valve is 17630-16040. It should cost about $70.00 and should be available at any Lexus or Toyota dealer.

This is a very common problem on first and second generation LS models and has been discussed numerous times. Do a "Search" for more discussion.

because some detection device that feeds your car's computer is sending a bad signal.

to find out which one, see your friendly mechanic.

Most of the cars have spare fuses in the fuse box so check your fuse boxes
