Hello! My name is Jake and I have an 04 RX330 with 230,000 miles on it. Not certain on the history of it but I have gotten it with no heat and an overheating problem(EDIT: previous owners said it has overheated on them). I immediately knocked out the easy stuff, checked coolant levels, verified fans were working. So I end up doing serious work that it needed: waterpump, timing belt, power steering pump, upper/lower intake gaskets, thermostat(THM 117-$11.32 at napa), valve cover gaskets, spark plugs. I end up finding smoke swirling out of a crack in the radiator while the car was idling for an hour during a fuel injector decarbonizing process. I end up replacing the radiator as well as the fan motors with the relay because the fans wouldn't turn on. I ended up using a power probe straight to the old fan motors and only fan #2 worked. I end up putting it all together-bled all of the air out of the cooling system with an airlift evacuation tool-and this thing is still overheating! Today I pulled it in and put the scantool on it-temp reads 244 degrees, so it's up there. I take a laser thermometer gun and the passenger-side (or upper hose) of the radiator read 183 degrees give or take and the part of the intake that the sensor screws into was around the same. So I thought it's only a $20 sensor, and replaced it-also considering it had a previous P0117 code(engine coolant temperature circuit low input). I know when the DTC is aiming at the input part of a circuit, it's talking about something with the sensor. I thought this would do it, BUT the car still overheats via gauge. Good news was I had heat, so I'd blast it when it starts climbing up and it'd slowly go down. I'm really stumped now, because I know the heater core acts as a mini radiator, but it doesn't make sense that the heatercore cools the engine down but not the fans and radiator being fully functional. The upper heater hose is piping hot with pressure but the lower hose is room temperature with pressure, I verified by squeezing the hoses. Is the thermostat defective? I installed it with the wobbler pin positioned at the top via installation instructions. I feel like I might run a compression test tomorrow to check the head gaskets, but I feel like I'm missing another sensor or something-I'm a freshman in college so anyone with experience I'd greatly appreciate it!
Hello all, I test drove a clean 02 ES 300 yesterday (looking for a clean, reliable car around $10k+/-). In my area, it's hard to find clean cars for this price. I could go with something new'ish like a Fit or an Accent, but I would prefer a used Lexus. In fact, I'm driving a 180k 97 ES 300 right now that has been solid as a rock over the last 85k.
It was owned by an older woman who died somewhat suddenly about 1.5 years ago. Her daughter drove the car from 84k-to-its current 94.5k.
The mother had it serviced at the Lexus of Portland dealer since new. I asked for a printout copy of maintenance receipts before my test drive and she had them there in the car. The copy wasn't a full printout with detailed service as some of it was cutoff or abbreviated. But, it was there and had a list of all service from 0-84k miles.
The car was listed as excellent condition. Always garaged (from original owner; was sitting in driveway when I drove it). I asked to see the car do a cold-start up. It was definitely cold, as it had a few cob webs around the rear wheel arches. The car fired right up. The owner has a newer Altima and Ford Escape, so they don't really drive this car.
Drove the car through town, through slightly higher speed back-roads at 45-55mph. I thought I noticed a slight vibration through the steering wheel.
Then I hopped onto the freeway. Not really when accelerating, but when I let off the gas there was a very noticeable shaking of the steering wheel. It was almost shocking to me. I noticed the rear tires were noticeably less worn than the fronts, as if they hadn't been rotated in the last 10k+ miles.
So what's the most likely culprit behind the steering wheel shaking at freeway speeds? More so when dropping the throttle?
One thing of not, when looking through the service records there was a "vibration in steering wheel" noted at 12k miles. Again, the record were cut short from the dealer printout.
I really, really like the car and made an offer if the vibration was remedied (we were thinking rotor or wheel balancing...).
Anyone have ideas?
Ok, at first , my car runs hot very fast. So i bust my radiator, bought a new one, new thermostat, so i cant fiugure out what the problem is. I finally saw that the cooling fans werent set up, i checked all the fuses, and that wasnt the problem,, so what could it be ?
