I would say the two peaks should be at the same height. In the UK, beam alignment is part of the annual MOT roadworthyness test, and the government publish a guide as to how to set them up: https://www.gov.uk/government/uploads/system/uploads/attachment_data/file/260552/headlamp-aim-guide.pdf https://www.gov.uk/government/uploads/system/uploads/...

If the manual says that 95 octane is suitable then the car will be fine with 95 octane. 98 will only yield appreciable performance gains if the ignition advance is being actively limited by engine knock. Since both engine and tune are set up by the manufacturer to handle 95, the impact of using 98 will be limited.

Safety glass will most always look the same no matter how or where it shatters, mainly due to the design of the glass. It's made to break into a thousand little pieces (you'll still find pieces five years from now if you still have the car ... they just get everywhere). I don't think you'll ever be able to conclusively figure out, with 100% surety whether ...

As Zaid said, if the manual says 95, use 95. Simple as that. Actually, using a higher octane rating is not ideal, whatever it may seem. From whatcouldbegreener.com: What will happen if I use higher octane gas than I’m supposed to? A few things. For one, you will be wasting a huge amount of money paying for high octane gasoline. Second, your car ...

Owners Manual is only a basic operations manual. Not worth paying for (did you not get one with the car?) The Haynes Manual is a good starting point if you want to do any work on your car. As you get more advanced, you'll want to get a copy of the Shop Manual; this is the gospel that the dealer mechanics work from (or should work from..). Much much more ...

The fuel filter on your vehicle is part of its fuel pump in the fuel tank. They are designed and made to last the 'life of the vehicle'. They have a plastic OBD2 fuel tank with an interior 'bladder', which means unless something other then normal operation causes damage they never have to be changed.

Was the factory solution not using a gasket? A gasket is usually better than the Room Temperature Vulcanizing (RTV) sealing method since RTV is really messy and hard to clean off during maintenance and is harder to apply which may lead to failure as you have seen. There should be no need to warranty the gasket. If it becomes an issue again it should still ...

There should not be a screeching noise when you use the brakes. (I take it that you mean the screeching sound is when you drive the vehicle.) You will have to dismantle the brakes to the extent that you did to replace your rotors and pads. You must check that the rotors and discs are exactly the same size and profile as the ones replaced. Check any bolts ...

tl dr - Rain-X is better than carnauba wax. I was reading an article by Wired Magazine about Rain-X. The article talks about how Rain-X works and is the basis for why it will (if applied properly) work better than carnauba wax in cool weather or in high heat. Basically, the main ingredient in Rain-X which makes the water run off is called ...

There are fluorescent dyes that you can add to oil to detect leaks. Here is an example - You can add it to the PS fluid reservoir, run the car a while, and then use a UV light around the engine bay to hopefully find the leak. I am surprised that a high leak rate such as this is not showing evidence on the ground.

Sure, this could easily be done as what's being displayed is just a video feed. You'd just need to leach off of the feed, which would then need to be provided to a recorder. That could be spinning disk, SSD, thumb drive, or flash card. That all depends on they type of recording device being used. There are systems out there which do this, but none which are ...

Step 1: Assuming the leak is coming from the drain plug, tighten it and top off your oil. Step 2: Stop going to Jiffy Lube. :)

Have you tried working the lock mechanism manually with the physical key? The door lock module you installed will have to be electrically connected. Also, check the fuse (20A) for "D FR DOOR". Or cycle the locks using the lock buttons on the armrest? If something is bound up, you will have to remove the module and determine the cause of the binding. You ...

P1135 A/F Sensor Heater Circuit Malfunction (bank 1 sensor 1) P1155 A/F Sensor Heater Circuit Malfunction (bank 2 sensor 1) There are two conditions that set the code: heater current exceeds 8 Amps or below 0.25 Amps. This can be caused by: an open or short in the heater circuit, a bad sensor heater, or the ECM. The sensors are grounded individually by ...

The OP resolved this issue as per his comment: The problem has been solved by changing one coil and cat repair. So the reason for the misfire was a bad coil, while the catalytic converter had to be "repaired", possibly replaced due to clogging.

If it's never been changed, then yes, I'd change it. To get 100k out of a fuel filter is a good life for it. Fuel filters are usually not too expensive, so are a decent maintenance item to take care of. They are also usually fairly easy to change ... usually.

The VLSS (variable valve timing) shuttle valve is bad on bank one. It is just under the rocker arm cover, but getting to the cover on bank 1 is the problem. I had the exact same problem on Bank 2 (cylinders 2 4 6 randomly misfiring) and replacing the VLSS valve fixed it!

Agreeing with @DucatiKiller here for the most part. There are a couple of things of note though ... The reason your engine seems to be running fine is because the computer will detect the "pinging" before you ever will through the use of a knock sensor. When the ECU detects pinging, it will start pulling timing (retarding your timing) until it stops pinging ...

Lexus recommends a 91 Research Octane Number (RON). Here is additional information related to octane ratings and standards worldwide. Gasoline has chemical components that have anti-knock components. Anti-knock components elude to chemicals within the gasoline that prevent the fuel from pre-igniting under compression before the spark fires. If your ...

The compressor is a scroll type driven by a variable speed 288 volt three phase motor. The speed is controlled by the A/C system controller that uses neural network logic to calculate the required refrigerant volume needed based on learned values of this vehicle in its usual climate and usage pattern. As for the TVX vs Tube question. The system uses a newer ...

I would bet the problem is not that the rotors are warped (this really doesn't happen all that often). The problem is probably that after hard braking and then a sudden stop without release for a period of time, there is a small buildup of brake friction material which has embedded itself upon the surface of the rotor. This gives you a pulsating feeling when ...

If you don't need the A/C, just leave everything where it's at. You may want to fix it in the future, so if everything is there, all you have to do is fix what's wrong and there you are. The pulley will spin freely, so no big deal there. If the refrigerant is all out of the system, it won't attempt to turn on. It's just a little bit of unused weight in the ...

Check the belts on the front of the engine. It's likely you have a slipping power steering or accessory belt. The belt could have stretched, or the tensioner could have failed. Replacing a belt is usually pretty straightforward, replacing the tensioner is a little more involved. If the belt seems loose, you may be able to tighten it using a tensioner (...

No, you can buy and replace the worn bushings, either from the Dealer, local parts store or performance parts sellers. https://www.startpage.com/do/search?query=2000+Lexus+RX300.+rack+bushings&cat=web&pl=chrome&language=english

If you have not yet purchased a hybrid vehicle and do not want a hybrid equipped vehicle can I reasonably suggest you purchase a non-hybrid vehicle. If you like the RX400h, perhaps an RX300 would suit your needs. Theoretically it would be possible to remove hybrid technology from a hybrid equipped vehicle but this would be very time consuming and costly. ...

Well, you already found the big hint somewhere else: Ben wrote: It would be hard to test the coils off the car without some kind of setup to generate the trigger signal. Actually I just learned that all 6 coils may not necessarily be bad. When an ignitor fails it can pull down the IGF circuit causing all 6 codes to appear. It doesn't always happen ...

So, the IS350 actually utilizes both port and direct injection. This results in the IS350 having fewer carbon build-up problems than the IS250, which exclusively uses direct injection. The dealer/shop procedure for this maintenance is, at best, to inspect the valves for build up. If you want to maintenance the vehicle as recommended by Lexus, take it to the ...

Just in case anyone else runs into this situation. Do not buy aftermarket parts or what are claimed to be OEM compatible parts for your Lexus. At least not electrical signal parts. I purchased two Denso sensors on Amazon and made sure they had the same markings as the original that came out of the car. It took another 6 hours to tear the intake manifold out ...

It looks like this is a common issue with this IS generation. There are quite a few forum posts out in the wild on the topic, and on how to adjust it. I decided to follow the recommendation in Nick C's post and am pleased with the results: Instructions to adjust the headlight beam Tools Required 8 mm close-ended wrench/spanner (preferably a ratcheting ...

According to this link if you can find a non-nav unit from the same year (though 03-09 seem to be interchangeable), you should be able to swap the hvac (heating, ventilation, AC) controls directly into your dash and have full control of the air flow. I've found a couple examples on eBay that should fit (example 2). If you're not comfortable doing this work ...
