2013 Ford Fusion ... My cars thermostat runs normal all the time unless I go up hill. I drive into the mountains to work every day. It runs about 80% hot until I crest the mountain and then immediately cools back down to normal. Since its winter no air conditioning running but heat is on at times. Only 37000 miles on car. Automatic transmission.....

View 7 Replies99 ford taurus 232000 miles. Great car I keep it fairly well maintained or my mechanic does actually. The thermostat was faulty and while in a long idle it shot all the way to HOT. The car did not over heat. the thermostat was replaced. A week later another long idle and it shot up to HOT again. A few days after that it was discovered I had a leak from the O rings going into the radiator part/section. They were replaced.
Yesterday I drove from work to the store about 25 miles. I got back to my car - started it up - it was rough/sluggish. I drove it 100 feet and noticed the RPM dropped or would not go up to where it had been normally. 40 to 45 miles an hour RPM at 1 or 1.5 .....It drove home "ok" but, I have had the car 13 years and I know there is something wrong. But I do not know what.
99 Toyota Avalon, 3.6 L engine, 160k milesThe engine sends radiator fluid to the overflow reservoir but doesn't suck it back into the engine when it cools.My mechanic replaced the radiator, cap, and hoses...no change. So. he put a chemical in the radiator fluid that is supposed to form a plug to stop a leak. After ~5 months of waiting, still no plug...no change. Tomorrow, I'm bring it back to him. If he says it needs a new head gasket, do you agree? If so, what would be a reasonable cost? Also, this timing belt has 68,000 miles on, do you think I should have him replace it, too (since he is doing work on the engine)?Do you think I am foolish to put the cost of repairs into this vehicle? The rest of the vehicle is good. We've had it since 2000 and have kept up with maintenance and services.
View 19 RepliesI have a 98 mitsubishi triton v6 3.0, I am confused with a issue I am having, coolant heats up and is put into reservoir tank as normal, but when car cools down it does not suck it back into radiator.
Have purchased new radiator cap.
No coolant on ground or any visible leaks in engine bay.
No white smoke when starting car or running
No sweet smell of coolant burning
No leaks inside heater
Car doesn't overheat, just pushes more coolant Into reservoir
Slight bubbles in radiator when cap off
No coolant in oil
Put a bottle of radiator leak fix in, no improvement,
Only thing is that 3 out of 5 intake manifold bolts are stuffed, they grab but don't get a tight fit, could this cause the vacuum leak not returning the coolant to radiator....
I have a 2012 Ford Taurus when I turn the ac on it goes fast and then back to normal every like 3-5 seconds. It blows cold air and it doesn't matter the speed of the ac it speeds up and slow back to normal. Has 49100 miles...
View 3 RepliesFor reasons I can't figure, the Temp gauge on the wife's Explorer is shooting from normal to high in just seconds. Then, it drops back to normal. When I looked at it this afternoon, I noted 2 things.
1) There was no sign of a coolant leak or overheating.
2) There wasn't ANY coolant in the tank!!!!!!!
The truck has evidently been running fine while this is going on.
I have owned an 03 Excursion that I have had since last November that has started to feel like the steering is badly broken for a few hundred feet some times and then goes back to normal. It will do it some times after taking a corner and then suddenly there is a 1/4 turn play in the front and its wondering in the lane as I correct it back and forth and then it stops and goes back to normal. I've checked it and it all seems good and tight. The truck is stock height and has stock size wheels....

My trans is skipping out of lockup for 1-2 Seconds and then goes back to normal operation with lockup engaged. I am shure that it is the lockup disengaging because the increase in rpm is not as much as between gears.
This happens appr once or twice every hour when driving at normal constant highway speed. It happens both in 3rd and in OD. There is no flashing OD lamp, and the OD button is working (I use this actively when going up hill to keep up momentum and rpm)
I am not able to find out what causes this. I have replaced the speed sensor on the rear axle, the rpm sensor on the engine and the brake light switch on the brake pedal. Replaced one item at the time to be able to determine if any of these items was causing the problem. But none of them made any difference, the problem is still there. I have also inspected the harness connector on the trans and it seems fine to me.
2004 silverado, 2wd, V6, 150,000 miles on it. New plugs and wires 2 years ago. New fuel pump and fuel filter last summer. Truck was running fine but I did notice the last couple of mornings while I was driving the headlights would dim a little bit then go back to normal. Yesterday afternoon it started like it was 15 below out. Turned over kinda slow. But it wasn't that cold out. Anyway the headlights and dash lights were really dim. I got the truck in the driveway, revved the engine and they didn't get any brighter. The truck started running ruff and eventually quit. When I tried to restart it, it just clicked. When I turned the key off the dash lights got bright again.
View 5 RepliesSo my understanding is the water temp gauge at 200 degrees is pretty much spot on. The last three days I notice the temp gauge go to 200 then up to 240 which is like just one line away from the red zone. I turned on my heat full blast and was on the tollway and the temps went back to 200. The moment I got back into stop and go traffic the temp goes up again 220-240 range. Again, one line away from the red zone. No other alarms or dash messages come up. No smell of anti-freeze.
As well, the oil temp which was always at 200 has done the same thing. Running over 200 in the 220 plus range. Could this just be low anti-freeze? If so, would I not get a dash warning light?
I have a 2015 IS350 FSport. I drive full automatic in Sport+ mode, and I notice whenever I decelerate, the RPM would spike up around 200rpm and back to normal within second. It is consistently when the gears are changing down. Is this normal?
View 9 RepliesI was driving at 60mph and all of sudden rpm drop to zero went back to normal rpm after 5 seconds, pulled over thinking I blew some thing every thing seem normal is this a sensor problem.

I have just bought a camry-LE 2010 that has high millage on it which is 120,000mi. when i tested the car, it seemed fine but after long drive I discoverer something. When i am driving at speed 45 - 50 and stabilize the pressing of the accelerator, I feel the car shaking for few second then return back to its normal mode . I do not why I feel something wrong with the engine.
View 3 RepliesI finally got my 20th to run right. But now and ever since I bought it the gas needle keeps going down and back to normal every time i make a sudden move or go through a bump. What could be causing it?
View 5 RepliesSo every morning I get in my car and start it up. Usually, It starts right up, hit 1.5K RPM and then drops to almost dead (~3-400RPM) and then goes back up to a normal idle. This has always concerned me but never thought too much of it since the car goes right back to normal after a few seconds. Today the car did the normal startup and then died. What is causing this?
View 4 RepliesI own a 2008 Bullitt Mustang. The past six months I have noticed a backfire. It only happens after the car has been driven and cools down for a few hours. It doesn't happen after sitting all night. The car is under warranty and my dealer says it is normal. The car also runs better when it is cold.
View 8 RepliesI have Toyota 4runner 1996 4 cylinder. it was running good (from time to time I would lose power for 2 to 10 second than it go back to normal acceleration). I had the check engine light on for almost 8 month. last week I took the car to mechanic shop for diagnosis. the mechanic changed the spark plugs and after that the engine lost power. the car cannot go over 30 or 35 mile per hour. He changed the spark plugs and put different ones, same thing he put the old ones back same problem, he changed the wires, the fuel filter, air filter, the distributor and rotor, but still the same problem. the problem is that the check engine light is off now and there no codes.

View 4 RepliesI have a 98 f150(4.6 V8) that has 'seemingly' overheated for about 5 seconds twice in the last month. I noticed the temperature gauge went all the way up after about 1 mile of travel, then it immediately fell back down to normal. The truck has 198k miles.
I flushed out the system using a Peak Flushing Tee, replaced the thermostat with spring facing the engine block, and refilled the system.
I haven't had another overheating instance but I am having problems with my heater....the truck seems to warm up fine and the heat starts off working well. The temperature gauge reads normal for a few minutes then drops and I lose the heat. The truck blows cool air for a while, then will start blocking hot air again.
I believe the water pump has been replaced fairly recently...the pulley has no slack and I don't see any leaks or wetness around the pump or its weep-hole.
I read it could be a blend door or blend door actuator. I don't hear any funny clicking and obviously get some heat.
Should I try another new thermostat? Intermittent water pump problems?
I've got a P0456 code on my 02 LS v6. I came to a stop at a light, RPMs quickly dipped twice from 800 to 400(ish) then went right back to normal idle (800-1000) and the CEL lit up. It seems to be running fine other than the RPM drops after coming to a stop.
I checked the gas cap, everything seems OK there. Checked the hoses coming into/out of Evap valve (well, assuming this diagram actually points me to the evap valve: [URL] .... and there were no major/detectable cracks. Any other hoses/fittings that I should check?
