Impala - Chevrolet :: 2005 / 3.4 - Overheating And Crank Shaft Pulley Wobbling A Little
Feb 8, 2011
I recently had an issue with my car overheating so I changed the thermostat. About 3 months later it happens again. I know I need a new tensioner arm but I decide to wait on it. I take it to a place and have the radiator flushed and the guy calls me back to the garage and says your belt fell off... i was like o man, so he showed me how it would slip off the tensioner and i said ok and put a new tensioner on. He called me back and said he found a new problem my crank shaft pulley was wobbling a little. I didn't have enough money to have him check it out further so he said he would just finish the flush and go from there. after he finished the flush he said there is still a problem with the heating on the car. He didn't know if the problem came from the pump, the t stat, or something like a sensor. and it would cost alot in research time for him to find the problem and fix it. so i am going to take it to another mechanic. I have replaced the pump about 2 years ago, I replaced the thermostat about 3 times before the flush over about 1 years time, i replaced the stepper motors on the gauges since they went bad. and now I am at a loss on what to do next. I just wish that click and clack would come fix my car.

I have a 2003 chevy impala ls, now I felt wobbling in the front more on the right a few weeks ago and it started getting worse especially when I would brake, I had it looked at by a mechanic who shook,twirled, yanked and examined my wheels and tires, and told me it just looked like I needed a new tire up there.So I went bought 2 new tires and had them out on. When they did it they took the rim from the right and rotated it to the left side. I drove off thinking the wobble was gone , but I still feel it. Now it feels like it's on the left side not as bad but you can still feel it constantly........ So I guess my question would be is the problem the rim itself then?

So this car has been having overheating problems since I first purchased it. I've operated it, but I've had to keep the heat going full blast to keep the coolant tank from overheating.
Last night I was driving on the interstate, and it began to overheat. It was running hot for maybe 3 minutes before I was able to pull over. I let it sit and cool for probably about 20-25 minutes, pulling over on a dark portion of the interstate, before I started it with no problem and moved it to a safer location (it ran hot again, but this was maybe for 30 seconds before I pulled over and shut it off.)
I let it sit for a good hour so that it could cool all the way down from 260 to 140. I then attempt to start it. It turns, but does not start. At this point, I call a tow truck to come for it. About 30 to 40 minutes after this, I start the car again. It starts with no problem. I put it in reverse, and roll it back to see if there are any leaks. There's leaking from the coolant tank...quite a large puddle. I refill it with distilled water and it leaks some more but sits mostly. I then start it again, and roll it forward. The tow truck arrives maybe 30 minutes later, and I attempt to start it to line it up behind, but it turns and does not start. We have to put it in Neutral and turn it to get it in line for the tow truck.
We get to my destination, probably about a 40 minute drive, and he unloads it. I attempt to start it...again, it turns but does not start. This morning, about 8 hours after that, I try to start it...it does not even turn.
The oil is just fine, the battery is not dead (lights/radio/horn/etc. works), but the battery does seem weak since the dashboard lights are dimmed no matter how much I turn them up. Even though the coolant tank has been somewhat depleted, it was never close to being empty or bone dry. There weren't any "knocking" noises, there was no smoking or anything from either the hood or the exhaust.

My 2005 Impala is overheating , sometimes, and only for a minute. (When it goes into the red, I pull over and turn car off for a few minutes.) The needle fluctuates, though. I read old posts, but my mechanic tried them. Here's what's gone on so far:
Replaced thermostat, flushed / refilled antifreeze , car worked fine for a day, then it started again.
He then took an air pocket out. He took it for a drive, it was fine. I drove it for a day, it was fine. The next day it started up again (needle quickly fluctuating, sometimes needle slowly fluctuating).
He replaced the upper radiator hose. He then drove the car (local and on highway) for 2 1/2 hours, it was fine. I picked it up and it was perfect for the rest of the day/evening. This morning, after driving about 8 miles, it started again. I'm dropping it off tonight. He said it is hard to know exactly what it is without trying things. He said next he would try water pump or radiator.

My 2002 Impala runs hot when pulling a long grade and I have to turn off the a/c. It runs fine every other time. New belts, hoses, thermostat and flushed completely with new coolant. The radiator is fine and a/c coils are clean also

Ok so my car kept overheating and I saw I had a small leak from the gasket on the water pump. I replaced the water pump and gasket but then it would zoom straight to overheating. I then assumed it was a stuck thermostat and replaced the OEM with a fail-safe thermostat. After topping off fluid and leaving the radiator cap off until I saw fluid running through it took it for a drive. The temp began to climb to overheating but dropped just as it was getting to the red and then began to fluctuate. Finally heat came through the car climate system and all was good until I had to come to a stop. It seems that whenever I have to stop at a light the temperature rises to overheating.

My 2004 Impala, 100+k miles, is occasionally not starting. The battery is fine, it's fairly new and we had it tested. When I crank it, I get all lights and electrics but it doesn't even make any crank noise or even try to start. I've read that the security system could cause this.

Had idler pulley, tens pulley, alternator and new belt replaced all within last 5k. Was just looking under the hood while it was running and notice the crankshaft pulley was wobbling. What is the best and worst case scenario?

Ok so I recently started noticing my car was overheating and the sensor would go off saying coolant temp hot. So I started by adding coolant that didn't work. I than replaced the thermostat didn't change. I saw the water pump was leaking and changed that but before I did I was driving it home one night and the engine stopped and I barely had control of the car. Now the water pump is new and I don't know what the problem is. I think it's the head gasket ???

My 1998 malibu starts most of the time, there is a continual light on the dash and according to the maintenance book from chevy, they are saying check your emissions system. Also on the times when the car does not start right away, the oil, battery light also goes on; the sound is rrrrr, weaker and weaker, wait 5 minutes and can start the car. This has been the pattern. Diagnostics say it is the crank shaft sensor..... I have already read your stream about crank shafts sensors.

I got this car from someone and I just noticed none of the gauges on the dashboard work! Everything else works fine and the mileage still shows, engine notifications still show, etc.It's a 2005 Chevy Impala. What might be wrong?

There is an odor when it idles both in and out of the car but only after some driving - if I sit there a while the smell goes away. It is most noticeable when I get off the highway on my way to work and sit at a stop light. If i have to sit and wait for someone, the smell dissipates. I cannot find a leak. There is a performance issue but I'm not sure if it's related. At highway speeds it is having trouble accelerating - if I'm at 55 and want to go to 65, it'll go but it feels like there's resistance, almost a pulling, it causes the car to rock back and forth a bit - again it only happens at higher speeds. It has 140000 and is in good shape (except for things mentioned). The last repair was a water pump replacement about 4 months ago.

About 90% of the time, my gas gauge on my 2005 Impala works just fine. However, sometimes on hot afternoons it has problems & it doesn't read accurately. For example, I will have a nearly full tank & the gauge will show 1/4 to 1/2 full, depending on its "mood". If I drive the car somewhere & turn it off, everything is fine after I re-start it. I have to drive it somewhere though. If I start it, turn it off right away, and re-start it, it still reads inaccurately. The car runs fine & there no warning lights are lit on the dash.

My mechanic tells me that the hold up or carrier bearings on the drive shaft of my 2005 Equinox need to be replaced. He says that about half the time this cannot be accomplished and that I might have to replace the entire drive shaft. From the research I have done, it seems that a press (?) and blow torches are needed to replace the bearings. I can't afford the new drive shaft, but I could afford to replace the bearings if I could find someone who was sure they could accomplish this.

I have a 2005 Impala with the 3.4 engine and 118,000 miles. About 2 years ago I had a code P0141 and since we didn't know for sure which oxygen sensor was out we replaced both of them. The P0141 code did not stop occurring after both sensors were changed. I read on an Impala forum that if you didn't replace the sensors with AC Delco the codes would continue so I didn't worry about it until my gas mileage starting going down recently. I ordered new AC Delco oxygen sensors and my husband replaced them Saturday, the old ones were sooted up pretty badly. Today a new code appeared, it is P0140, O2 sensor circuit no activity. What the problem might be now.

I was hearing some sounds from my engine and opened up the timing covers to determine where the sound was coming from. It sounds exactly like the Sienna with the same 3MZ engine in this video: YouTube ....
While I didn't find the source of the noise, I did find that my water-pump is leaking. My question is, is this water-pump leaking bad enough to be replaced? I do not notice any coolant loss and never had the need to top up.
It appears from this last photo that the pump is leaking through its pulley shaft and not at the interface with the engine:
The timing belt and water-pump were changed 3 years ago with the Gates timing belt kit from RockAuto. The pump at the time didn't look that great quality in its casting compared to an Aisin pump.
I could not feel any play or hear any abnormal sounds from the pump while it was running with the timing covers off.
This is on my 2005 Lexus ES330 with the 3MZ-FE 3.3L V6 engine, same motor as the Gen 5 Camry SE V6.

Recently I've been noticing a gas smell after parking my car after the drive home from work, but engine performance and mileage efficiency didn't seem affected, and I found no visible evidence of leaking on the ground (nor in the engine, but I likely don't know the right places to look).
Today, with the engine running, I looked around the engine to see if I could locate any gas leakage -- I located the fuel pressure regulator (I think; a golf-ball sized acorn on the right of the engine with a hose coming in the top and a pipe coming out the bottom and going down and to the left) and didn't see any leaking during my brief test. I'll check it again after my drive home tonight.
One new thing I did discover, though; while in park, when I slowly pressed on the accelerator, there would be a point where the engine started losing power and going into a rev/slowdown cycle: about a second or two of revving, then a half second of slowing down. This was while cold and in park; I've not experienced this in normal driving.

Last night at 2am and it was about 10 degrees out (I say the temp because it might matter?) I started my car, let it warm up to normal running standard and backed up. My car moved backwards but the wheel would not turn at all. I pull forward into my parking spot and noticed that the wheel is extremely hard to turn left or right... almost impossible.
I check under the hood and noticed that my car was leaking something onto the group but it was dark and I couldn't quite see what it was.
Checked this morning and I found that my power steering fluid was completely empty. I had a half bottle in my trunk and put it in my car, then turned my car on. All of a sudden I noticed that the fluid is leaking onto the ground. Not really leak, more like a slow/medium pour and the wheel still wouldn't not move.

Preparing for a timing belt replacement on a 2007 elantra. well aware of how to remove the crank pulley and do the job. My question is this : once you have the nut off, does the crank pulley come off by hand or is a puller required? came off nicely wiggling it by hand on any accent i've done, but never done this particular job with the elantra.

So, yesterday I had my GLI in the shop to put a new timing belt on as well as some ECS Lightweight Pulleys. When I went to pick up the car, they did not install the pulleys. The reason they said was because the stock crank pulley has a dampener which keep vibration and balanced weight on the crank assembly and that the lightweight crank does not have these benefits.
So, now I have a set red anodized pulleys.. [URL].............
