Lexus SC430 :: Temperature Gauge Rose To 3 / 4 High After Driving
May 17, 2016
I have an 02 SC430 and I recently noticed that my temperature gauge rose to 3/4 high after driving pretty hard on the interstate and then coming to a complete stop on side street traffic (mind you, it was like 95F outside) After traffic cleared and i started to move, the temp gauge went down to 1/2 and never rose again.
I tried to replicate the problem by having the car on idle and revving for a few minutes, but she stayed at half. I told my brother to watch the temp gauge if he drives it. He said the coolant was low and added coolant. Driving today, storming like hell, on the exit, i pull up to the red light and notice my temp gauge is to the cold position, but i have a check engine light on, VSC light on and VSC off light. I also noticed I'm smoking like hell, so i pull over to the nearest covering and pop the hood. My rad cap has popped off and coolant has spewed all over the engine. let it cool down and put the car on accessory.
At this point, my temp gauge is still at the cold position. started it up with no problems and the temp gauge shoots to the overheating position. I shut it down, let it cool. After a few minutes, i fire it up and drive it to the nearest gas station maybe 1000 ft away. Filled up almost 2 gallons of water and let it run with the rad cap off to get the air bubbles out. I notice a lot of air purging itself out of the coolant system. after running for 5 minutes with no variation in my temp gauge, i drive it for 5 minutes with no problems, no funny sounds, no funny misfire, no smoke (front or rear). The lights still have not come off... I can only attribute the overheating to air being in the cooling system.

The temperature gauge continues to go above the half way mark. Yesterday it was 88 here and I ran the a.c.. The gauge got a little over the second white mark from the top. I don't know if this is normal, I have taken it to a mechanic twice and he said I had nothing to worry about.
I am just used to the gauge staying right in the middle, and this one does not do that. The fan that cools the engine is almost always on as well. This is another thing that leads me to think there is a problem.
Would you mind telling me if your 430 gauge moves around like mine? I have to get something done before I hurt the engine?

What is the location of the Coolant Temperature Sensor? I search but I couldn't find a picture or diagram for our car.

One day, I was on the highway and my Pontiac's speed started dropping. I looked at the temperature gauge, and the temperature was really high. I flushed the coolant system, and changed the gasket. Also the mechanic said that the oil might be leaking after they changed the oil. I paid like $700 for something that has nothing to do with the problem (I paid for a spark plug, ignition wires, fuel filter, and an oxygen sensor). After they changed the oil, oil started leaking all over my driveway, which didn't happen before. It also looked like coolant was leaking out. None of this happened before I got my oil changed with these guys.
After I changed the gasket, the car was running smoothly. But today, the same thing happened again, and I don't know if it's the thermostat, or water pump, or oil leaking, or coolant. The mechanic always suggests to fix something that doesn't have to do with the problem. I don't have much money on hand, so I need to only fix what has to do with the temperature rising, and I need my car to run.

Temp gauge not working stays at C doesn't move at all. And smelling anti freeze while driving. The heat still works and not wet on carpet of passenger side. Does have an oil leak I think since I've had to add more oil again. Would that have anything to do with an antifreeze smell tho? Just checking before I have it looked at it. Also the gas gauge just floats that hasn't worked in a while though.

I have had my 1998 Honda Civic for about 5 years now... I bought it used. Occasionally I have noticed my oil levels have been low every 2 months or so. Oil is not being burned and doesn't leak. It hasn't affected performance from what I can tell. I have basically monitored the levels and everything has been fine. There was also an electrical issue since I have had it.
About 8 or 9 months ago, I noticed the temperature gauge was basically in the red while driving. I pulled over and noticed the oil was reading empty. I put oil in it and took it to the shop the next day. They told me the head gasket was bad and that the oil and coolant were mixing and recommended I replace the engine. I asked them how long I could manage before the car quit entirely and he said maybe a month, two if I kept doing oil changes.
I put the heat on while driving it, and the temp was normal. I took it to another shop the same week. They couldn't get it to overheat for a couple hours. The guy told me it was probably the fan but wouldn't know unless he could see it overheat. He said the fan would cause it to overheat at stoplights when there wasn't air on the engine. When the car gets hot, it doesn't get worse at stoplights and is only after I've been driving like 20 minutes that it heats up. I asked that he call me as soon as he knew what it was and I would decide whether I wanted it fixed that day or not. Then I didn't get a call for awhile, and when I called them, they said the guy was out getting the part. I felt like they were rushing so I would replace the fan. I asked if it was the head gasket because I didn't want to fix a fan if the engine needed to be replaced. They said it was not. I didn't replace the fan. They also told my husband that we could save wear and tear on the engine by putting the air conditioning on instead of the heater. When we do this, it overheats. Its only when the heater is on that the temp stays normal.
I have been driving the car for 8 or 9 months now with the heater on with no performance issues. It doesn't overheat and even when I forget to put the heat on it goes up to the red, but doesn't "overheat" with the steam and whatnot. It doesn't seem to do anything to affect the performance of the car. We have replaced the radiator cap, which had pieces falling off, and it didn't work. The check engine light came on yesterday and the code indicated something to do with the transmission.
We took it to a third mechanic today and he said I needed a new thermostat... I do not see any sort of film in the oil. We just flushed the coolant today and there was no sign of oil. I'm totally lost on what to do. I feel like the mechanics have lied to me about what was going on. They contradict each other and the little things they told me don't seem to be the case or don't work.

When taking our 2007 RX out of say a 72 degree garage to say a 90 degree day, it takes at least 10 minutes for the outside temp gauge to finally creep up to the ambient temperature. The gauge feels very sluggish at all other times.

When I drive 30 min the oil temp raises up to 110c and the coolant raises up to the redzone. And when I stop for a red light my front window get fogged all the way I can see barely anything.
Coolant is filled everything is okay. Only sometimes its really low or when the engine almost hit the redzone its a bit empty. No leaks nothing. Now my vds says 2 errors :
Fan 1 blocked
Fan 2 blocked
When the engine is warm the fan doesn't turn on none of them does, today at the local shop the worker did something and they started working but it doesn't turn on now its off and stays off is the fan switch dead? Is it really the the not working that's causing so much heat.

My 2004 RX330 which has gone many years without a problem suddenly has instrument panel gremlins.
I started the car a couple of days ago (it had rained during the day), and the airbag light did not turn off. Then the TPMS warning light came on, the water temperature gauge dropped to zero. The AC controls stopped responding. Since I needed to get home, and the car seemed otherwise fine, I drove home, after a few minutes the transmission "D" drive light went blank and the instrument back-light went to full brightness.
A few minutes later, all the warning lights went off and the back-light went back to normal. The AC controls still seemed to be off. A few minutes later the airbag warning light came back on, followed by the TPMS light and the back-light went to full brightness again. This cycle kept happening all the way home.
The next morning, hoping the problem had been some errant water getting into something, I started the car, opened the driver's door to get something and got back into the car, closing the door. The light showing the door was open stayed on. I put the car into reverse, the doors did not automatically lock as they usually do. I turned off the engine and restarted it, most of the other lights were off, the doors would lock; airbag & TPMS light came back on.
It has stayed that way, except I also get the A/T temperature warning light coming on periodically, and after some cycle it goes off.
I borrowed a car code reader, it does not seem to show any error codes. In reading some other postings it has been suggested that the Brake light switch is the cause, but the brake lights come on/off without any problem.

If i have the radio volume up fairly high, it will keep cutting off for a few seconds then come back on. then cut off again etc....
I presume the amp is getting hot and causing this, am I right? And would I need another amp, or maybe there is a fan in the amp not working? Or am I not even close? Its pretty annoying when that good song comes on and it cuts out.
Its not the actual radio that cuts off, its the sound from the speakers.

Just about every trip i take my temp gauge pegs and dinger goes off and check gauges lights up in the message center. It eventually will go back to normal or if i shut key off and restart truck it goes to normal. im guessing it is the temperature sensor for the gauge but not sure?? If it is, where is the gauge sensor located?

Lexus has diagnosed a ground fault with an intermittent connection.... I am not sure how to proceed ... Could it be a light bulb connection... or does it even have these? Can the part be serviced in place... or must I replace the whole assembly?

I have a 2006 Jeep Liberty 3.7L that has a temperature gauge on the dash that reads an overheat when driving. The oil looks normal, there is no white smoke, no bubbling from reservoir. I have replaced the following:
Radiator
Thermostat
Water Pump
Coolant Temperature Sensor
Coolant Reservoir Tank
I am not leaking any coolant and the reservoir level has been fine. I have let the vehicle idle for 20+minutes, with no overheat. When I drive it around, the temperature gauge will read an overheat. When I stop the car and pop the hood, the engine is not overheated and both rubber hoses to/from radiator are flowing the coolant. The only thing that will bring the gauge down is turning on the heater full blast. Could this be the gauge itself being bad? Could it be a short in a wire somewhere? I had thought maybe a head gasket, but have no symptoms of a head gasket.

So my sc430 keeps giving me trouble and all the lights come on while i am driving and then it shuts off on me. I could be wrong but i think it has something to do with a iphone connection that i have. I originally thought it was the battery so i replaced that and it was running fine for a day with no issues. Then today shortly after i tried to use the iphone connector the same thing happened.

I test drove the sc 430 the other day, I found it very smooth and very soft ride. I noticed that when I accelerate the car feels heavy as if it lacks the torque. Is this normal?
Also, the steering felt loose at high speeds above 60mph. Is this normal?

Its not super cold but in Tampa ever since I installed my headers and its 60 or below i've gotten the VSC and ABS lights on in the dash after driving a little bit. Typically this is a cold morning type thing.
I reset the lights and it went away for a few days (it also got 30 degrees warmer) once it got down to 55 the lights came back on. Parked the car went in to work and when I drove home the lights were off (without re-setting the lights).
I know the codes can mean different things. The car is driving the same as always too- I have PPE headers, Ingen Intake, and a muffler delete.

I have a 2007 and I've just developed my first problem since I purchased the car new in 2007. While driving, my headlight(s) will turn off by themselves.
Sometimes it's the right one, sometimes it's the left one, and sometimes they will both stop working. Turning the headlight switch off and then on brings them back to life.
What part in the headlight system is causing this?

About every 10 to 20 minutes while driving I hear 5 or six intermittent beeps. No warning lights or anything, just the beeps. What is it? I have a 2002 SC430.

I had a issue today and it made me scared to drive the SC ever again. While I was driving this light came on that kept blinking and making a beeping noises, after a while of blinking (approximately 30 seconds) the steering wheel jerked to the left and right really fast, luckily there was no car around me. I immediately pulled over to the shoulder. After a couple minutes I drove home on the service road without incident. Why this happened.

I have a 2007 and lately the driver's side headlight goes out sometimes when I'm driving. If I turn the lights off, and then back on, it will light up again and stay lit. Sometimes it will work for weeks and then all of a sudden it will go out. So I'm thinking of replacing the bulb(s)
Are the headlight bulbs in the 2007 SC regular light bulbs that I can purchase at a local automotive store?
