Question about Lexus ES 300

Open Question

I have a Lexus ES300 that has developed a loud humming sound at certain RPMs after the engine is hot. The humming stops if I speed up or slow down but does return. It is not always the same RPM and it use to only happen when it was raining or had been raining. Any ideas? I also have the groaning steering but that doesn't bother me too much. Also, check engine light and trackoff lights are displayed. Changed the o2 sensor so we think the gas cap seal is the problem. any idea where to order a gas cap?

This has been happening to my car as well. It typically happens when your oxygen sensors start to wear out. Mine does it once in a while and I have the local auto store reset it. Go to your nearest auto store and have them tell you what code it is and ask them to reset the OBD so the light goes out. If the light comes on right away and the code has to do with your oxygen sensors, have them replaced. There are three, two are easy to replace, one takes some effort as it is in a tough to get to spot. The dealer will charge you a fortune to replace them so do it yourself or through a local mechanic. It is a very simple task other then the access.

SOURCE: 1999 Lexus ES300 Steering wheel make groaning noise

Hi
If the groaning sound is still happening, you are probably low on power steering fluid. I suggest starting there. Remove the cap and check the dipstick attached to the cap. The reason the sound would go away at high speeds is that you don't turn the wheel as sharply at higher speeds so the pump is not trying to pump air ( that's the groaning sound ).
If you are low on PS fluid, fill it but check for leaks for a while. Look under the car in the morning for fluid. If you spot a leak, take it back to whomever replaced the hose and have them fix it.

As far as the engine light goes, first make sure the gas cap is on properly, meaning all the way. Turn it till you hear it click several times. If that is all it was, the light should go off after 20-30 miles or so. If it stays on, try changing the gas cap. That is probably one of the cheapest routes to go.
Good luck

Can a fan clutch cause overheating in colt bakkie 2.4


It most certainly will especially sitting at lights. high engine rpms and slow speed or loaded . If the engine cools down as soon as there is air flowing through the radiator then the hub will be faulty. If the fan is not making a roaring noise when hot ,the hub is faulty.

Sounds like something is caught up inside or outside the engine/transmission where a part is grinding from something reciprocating. Does the sound happen when you apply the gas without the car moving? If the sound only happens while moving then it could be suspension or transmission related. If it only happens with or without the car moving as long as you control the gas then it's probably in the engine or transmission related. Could also be a wheel bearing issue, that will be a humming sound inside the cabin. As you speed up the pitch increases and the opposite happens when you slow down.

This is normal. I also have a 2000 ES300. This became a problem when i tried to run an aftermarket sub off of the wire leads from the stock sub-woofer. When I would switch the radio off there would be a loud, deep, constant bass tone. As far as I know you cannot stop the voltage from continuously supplying the sub-woofer this is the way the factory amplifier is programmed, however, if you cut one of the wires(youhave to cut because wires are soldered to sub-woofer) the humming noise will not occur when radio is shut off. Cut the wire in middle and add crimp connectors so you can reconnect later if needed. You only need to cut one and it doesn't matter whether it's the black or red wire.
