1992 Lexus Ls 400 - Page 4 - Answered Questions & Fixed issues

YEP IGNITION TIMING OFF.MOST OF THE TIME WHEN YOU REPLACE TIMING BELT.THE IGNITION TIMING HAS TO BE RECHECKED.

Check battery first........connectiions at battery and under vehicle at starter......You need a testlight
to check for power at starter when you try to start it....(2 man operation).....If you dont have power at starter when turning switch more than likely switch or relay is bad....More than likely have a faulty starter / battery / or bad connection

batteries will show 12 v and still not have enough amps to start the vehicle, clean all the connection points on the battery , and charge it fully, start the vehicle and check again for voltage at the battery posts, you should have a reading of 13.5 to 14.5 volts, if not, yes you have a alternator malfunction,

Check your fuel pressure and check for spark.

Remove a spark plug wire (from spark plug end) and use a paper towel to dry around the plug. Replace plug wire and repeat for each additional plug wire.

Do not get your plug wires mixed up or you will have a very big problem compared to what you have now.

This is the most likely cause of moisture issues.

Hi,
Most likely a brake caliper or line. Lines are fairly cheap, calipers cost about $75 a piece if you get them discount online. Novice mechanics can do either or both replacements. DOnt buy parts from a dealer, they are 40% higher than retail. A brake shop will run you in the range of $150 to replace the caliper and pads one one axle, about $300 on both rear (replace both is recommended). Mike

There is not a drain hole. This sounds as if the heating coil is clogged and needs to be cleaned out. Its a job to get the heating coil out and is probably best left to a mechanic since you are working with/around the airbags of the vehicle and so forth.

you remove the compressor and exchange it for a rebuilt one, many companies rebuild them. then you install the rebuilt one and have a shop which does A/C work recharge the whole system.

here ya go

I have a 1992 LS 400 and twice it has not shifted out of second and I had instrument lights give false information and once it would not start. Long story short, all problems were caused by broken wires in the bundle by the left trunk hinge. My mechanic lengthened the broken wires and dressed the bundle away from the hinge. So far, so good. Remember the old computer adage, garbage in, garbage out ? This is true re: this car's computer.

Check your radiator for any leaks first. If you find leaks, this needs to be fixed by patching it up. If there are no leaks, Check the sensor inside of the radiator and make sure that it is not rusted away or broken. If it is, it could be giving false signals to your vehical, making the radiator light turn on. Hope this helps! Please rate 4 thumbs up!

this problem could be the eletronic part of your ignition switch.

the compressor has two hses coming out of it and one of the hoses/lines will go towads the radiator to the condeser the other will go towards the firewall,,under windshield ,this is the one with the low side service port it will be the small port on the larger line/hose the other one is a large port on a small liquid line/hose,,,,the small port is the one u will need to hiook up to ,on the large line/hose

With hot summer temp. i would use a High Millage oil and 10/40 wt.Being a 1992 and i'm sure high millage. good luck . hope this helps you out.

Hello
I suggest you have the transmission range range selector switch replaced, it may be shorted and this can cause havoc with the transmission operation. You also need to have the computer control module (known as the "TCM") for the electronically shifted transmission checked for fault codes, this test is very important, most Aamco transmission shops can do this test fro free, the results are crucial for diagnosing the problem.

what i do here is take them off and take them to hydraulic shop and they renew the flexible hoses for me which is a fraction of the price of the new item ,normally i pay around 20 euros depending on the length

Sounds like you have a short in the wiring for your brake lights unfortunately this on of those things that you have to take to an auto electric shop. Good luck some times those problems can be pricey.

YEP FUEL FILTER IS LOCATED UNDER THE VECHICLE ON THE DRIVER SIDE BEFORE THE REAR AXLE.

Starter fluid --is for small equipment
