Dakota :: 2000 4.7L V8 Overheating In Idle / On Highway At High Speeds And While Driving Slow
Jun 26, 2012
I drive a 2000 Dodge Dakota Sport w/ 4.7L V8 engine. I have been dealing with an overheating problem for about 6 months now and have nearly exhausted all hope of correcting the issue. It has been in the shop on 4 separate occasions and seen 2 different mechanics. The radiator has been replaced, the thermostat and thermostat housing have been replaced, the radiator fan works properly, hoses have been replaced and no subsequent leak has been found by either mechanic, they haven't mentioned the possibility of a blown Head Gasket (nor has the typical "milky residue," shown up in my oil cap). Each time I got it back from the shop the problem was fixed for about two weeks, then returned and slowly got worse.
It overheats in idle (with the fan running), on the highway at high speeds, and while driving slow. Sometimes it only gets about 3/4th to the red (usually when its cool at night) and sometimes it will hover just below the red; while I'm doing everything I can to keep it from hitting red (defrost on, revving engine). Some days it takes a little while to get hot and some days it happens very quickly. I'm tired of sinking money into the vehicle but as a recent grad I don't have the money for a new truck at this point. Suggestions included heater core clogged, water pump gone bad, fan clutch.

When I am driving, especially at high speeds on the highway, the Navigation System on my Prius runs pretty slow. As the GPS icon is traveling, the movement is very choppy. It is not a smooth transition. Is there any way that I can fix this?

I have a 2005 Dodge Magnum with the V-8 Hemi and after re-fueling the car will die if driving slow or try to die if driving at highway speeds. This only last about 5 minutes if driving down the highway and stops after a couple of restarts in town. The car will start back up without a check engine light. We have tried different gas stations and putting gas in when empty or 1/2 tank and still does it most of the time.

Purchased one owner Prius from Honda dealer May 2014 with 92000 miles.Now 2 months later 94000. Both service departments of Honda and a Toyota dealer said my car handles normally for a Prius.The car dips from left to right while driving at slow and highway speeds. It feels like a boat moving through water. The suspension was said to be good.Driving it feels unstable, like a Montero Sport or a stage coach. I wanted to do a lot of driving this summer, but this feels so uncomfortable.

Getting some vibration at high speeds on the highway, and when I changed my wheels, I noted that there seems to be some free play in the ball joint on the end. Is this normal? Can I replace just the end of the tie rod?

My wife's 2005 Escape Hybrid has recently started acting up. After a bit of driving at semi-highway speeds (say 10 minutes), when you slow down to a stop- the car stalls out (or what feels like a stall to someone who drives a std transmission car). Sometimes, it comes back on when you turn off & on the car- sometimes it takes a minute of being off to turn back on. After a few cycles of this, the engine temperature warning goes off. After each stall, the car will be ok for a few minutes then stall again when slowing down (it seems to do it when you are under 20mph only- not that I am about to try to stall it at high-speeds). It has circa 70k miles on it, and is obviously in the shop- as it is unsafe to drive. It was a warm day when it first did it (say 80deg), and cooler (50) the next morning.

I drive a 2002 4-dr 1.6 L Accent and there is a strange, high-pitched squeaking that comes about from somewhere under the car at very slow speeds (30 mph or below). If I hit the brakes, the noise continues sometimes as the car slows. (The noise isn't the brakes, though, I know that), but if I hit the gas pedal slowly, the noise stops. Whatever is vibrating underneath doesn't seem to be causing a problem at high speeds. Or I just can't hear it.
Secondly, I am going to try to do some tune-ups for the summer for lack of better things to do, mostly, I can pretty much do anything (intake/exhaust, engine, electrical) as long as I can find detailed instructions.

2004 Grand Cherokee. I was pulling a heavy trailer 1000 miles, and while coming down a mountain pass 50 miles from the end of the trip the check engine light came on. All other gauges (oil pressure, temperature, etc.) had not changed while climbing or descending and I was in low gear while descending to save the brakes. I drove the rest of the way to the destination without incident. I tried turning the Jeep off and restarting it several times to see if the check engine light would turn off and it stayed on. The next morning the light was off when I restarted it and has not come on again since. I hooked it up to a scan tool and received 2 codes: P0152 and P0132. 2 days later I noticed that it was revving high while idling and in Park. It would rev between 1500 and 2200 RPM while in Park, and at 900 RPM while in Drive. Also, while travelling at freeway speeds it seems like it's trying to downshift for no apparent reason. I hold the throttle still and have even tried cruise control and it intermittently increases engine speed, without changing ground speed. I assumed that I got the transmission too hot while climbing/descending and that the error codes listed above (related to O2 sensors) were associated with that, but now I'm wondering if something more has happened.

I just bought a 2011 accent 5 spd ... Quick question, when I drive it at highways speeds. (65mph) I notice that i am running around 3500 revs. Is that normal? It seems a little high to me. Every other 4 banger I had never ran that high in 5th gear at 65 mph.

I drive a 2003 Pontiac Vibe GT (6 speed Manual) and I have noticed that when im in 6th gear going highway speeds, I have an RPM of about 3K. For this model I feel this value is high and im worried about engine wear and fuel economy. I'm not sure about the other gears, but from my knowledge of other cars in the same weight category, less horsepower and 4-speed automatic gearbox, my car should not have such high RPM.

I've got a 2000 Suburban 1500 4WD with the Auto 4WD. I'm running into a vibration at highway speeds along with a clicking sound at idle speed which speeds up and slows down with speed. I've discovered the u-joint on the front drive shaft where it connects with the transfer case is worn and has play in it. Could this cause the vibration?
Also, The front drive train spins any time the vehicle is motion, which is to say the front drive shaft spins as the truck goes down the road, correct?

2000 taurus se w/20K miles, transaxle warning light begins to flash while driving at highway speeds only (w/auto climate control on, I think -- at least the last 2 times it happened, shutting off AC or heater allowed me to drive on w/o the warning light coming on again).
I stop and restart the engine and the light is off. May come on again in a few miles or not for a long time. No noticeable shifting or driving/operational problems.
Does it in D1 and in D. I'll have to take it in to get checked but want to be knowledgeable in order to save a mega-buck diagnostic that fails to address/correct the problem.

I have a 2007 dodge Dakota with 112K miles. At 105K I had the front brake rotors and pads replaced. The rear brakes were fine. There was a problem with one of the rotors and I returned a week or two later and one, which was warped, was replaced. Ever since that second visit I have had an intermittent vibration from the vehicle. When I brake the whole truck vibrates. And by vibrating, I mean some pretty heavy shaking. It is not the steering wheel vibrating. I took this back to the mechanic where they were unable to find any issues with the brakes. Also, we could not (of course) re-create the issue while it was in the shop. I have not been able to find the pattern. It happens when I am braking at high speeds, but not every time. It also happens at lower speed, but again, not every time.

1999 F150, 6 cyl. 4.2L, 233,000 miles. My temp gauge went way high on the interstate so I assumed I had a bad thermostat. replaced it with a genuine Ford themostat, added coolant and here's where I'm at.
1. Let it idle up to operating temp. When it was warm, the heater was blowing cold air.
2. Thermostat opened up, top radiator hose was hot and full of coolant, still no heat in cab.
3. Took it for a ride on the hwy. Heat started to work in cab, temp gauge went way up. I slowed down and went home down a side road. Temp gauge went back to normal and stayed there. Only driving about 30 mph.
I don't get why I'm overheating at 60mph. My best guess is I have some sort of obstruction in the cooling system.

I have a 2000 sc2 saturn DOHC 1.9 engine with just under 200k miles.
My problem is this, I recently purchased this car and was told it is in desperate need of a tune-up, being broke I decided to replace the cheapest parts first. I started with spark plugs, they are all gaped at 0.40 and all are new and the right ones for the car, ever since i changed the spark plugs the car has been idling rough (when i start it rpms go to 2500+ for about 10 seconds and drop to about 800-1100, when i shift into any gear it revs the rpms back up and they drop gradually). My other problems are that my car sounds like it is souped up and sounds like a rice rocket, when i put it in drive it starts to accelerate on its own and has reached around 40 mph at a gradual increase.
My uncle who was a mechanic said it could be the IAC, EGR or throttle position sensor, or cadilityc converter i replaced the IAC and it don't really seem to have worked much.

vehicle 1997 dakota engine 3.9L w/autotrans.
The vehicle exhibits an intermittent high idle. I have replaced the usual IAC stepper motor and checked the tps for proper function, also completely cleaned, inspected and relubed the throttle body and linkage.
According to my Inova 3140, there are no codes and the temperature sensors and tps percentage are reading correctly. Also the battery and charging system are functioning correctly.
I do not have bi directional capability or the ability to monitor any of the pid'sOne other thing is that she also has a slight rough idle, but that could be the 200,000 miles.

I have a '99 Dakota 4 cylinder. Starts fine but as it warms up or if you gas it the idle stays high. The more you run it the higher it goes. Have replaced MAP senser, throttle position and air bypass with no effect.( map and high tps voltage only codes shown ) Vacuum problem?

I'm talking basically about the equivalent of your standard pulse and glide in the regular Prius. But the PiP would allow you to do it up to 62 mph. However, you would manually have to toggle the HV/EV button to do it. It would be tiresome.

One thing that makes me nervous is the slow deceleration of the c at high speeds. My commute to work is an hour on the highway.

My '97 Honda Civic overheats when driven at high speed on the highway for more than an hour. I've changed the thermostat and the radiator fan, but it still does it.

i have a 2004 Mitsubishi lancer es 2.0 engine, and it's an automatic. I seem to consistently get a little under 23 mpg no matter how i drive. I've noticed that when going down the highway at 65 mph, it is at like 2900 RPM, is this normal? We also own a 2010 toyota corolla 1.8 auto and it only revs like 2400, and a 2005 xB that revs the same as the corolla, i'm just confused that with a bigger engine, it would rev so much higher.
