the radiator fan runs always with key on. Since it is driven only up to 10- 15 miles and Honolulu is warm I haven't been too diligent in finding the problem. Will it wear the fan motor out prematurely (110 K on engine)?
View 6 RepliesI have a 1990 Toyota pick up and, even though I have had the radiator removed and tested twice for leaks, I still loose fluid. I drive 30 miles - after having filled the radiator to the top - and then find it empty. The overflow radiator fluid bottle is always full to the top but the radiator will not stay full. My radiator man has told me to place a large piece of cardboard under the car to see if there are any leaks - there are non. I pay more in coolant than I do in fuel!

View 7 RepliesYesterday after driving my 1990 Integra ~ 25 min (Fwy), upon parking at the Farmers Market, I noticed the Fan running, which it usually NEVER does, unless there are impending issues (like in the past, when I needed a new radiator). I also noticed a weird smell, and even a stronger than usual gas smell coming from near the engine area, but thought it could have been from other cars near me that were coming and going.
This morning I opened the radiator cap and found the liquid slightly low, but there was still stuff in the overflow reservoir.There are not ANY signs of leakage under the car, but I now think the smell I noticed yesterday WAS radiator fluid. The hoses all look fine and the radiator is only a year or so old.
FYI, I tried to search Radiator queries under Repair and Maint. and the "ask a question " section, but it is not giving me the BLUE links that I USED TO GET, (as in others on the forum who posted radiator problems), but rather the links are RED now, and when I click on them, it often comes up as UNTRUSTED site, so I don't want to go there! Maybe the format has changed and it is ALL like this?
I got a 2004 VW Touareg, V8, 4.2L, I really love it and it's a nice one.
But since last winter (Dec. 2015), I found that the only one of the radiator fan (the large one, there was one larger fan together with a smaller one right under the hood attached to the back of the radiator) is working after I pulled my key off. I have to say probably I didn't notice it before but this time it drains the battery. I didn't drive it for 3 month since then since I was abroad for business. But weeks ago I started to jump start it whenever I need to drive, and the battery was drain after completely and can not be jumped any more.
I got this battery about 1 year ago (Feb. 2015), the repair guys put a "Super Starter Extreme" for me, I found it yesterday when I decided to change the battery by myself and drop the car to a near repair shop.
Here is the previous battery link. [URL] .....
(To be honest I'm not sure if this one is really a choice for my car, but it worked for a year).
And I have to go Walmart to get a new battery in 'cause that's the nearest place I can go for my convenience.
I get a "EverStart" by search with my vehicle model. [URL] ....
Now I can start the car and drive but the radiator fan will still keep working like 4 minutes after the engine is off.
If this is a normal situation, I checked online, a lot of people don't take it serious and say it is the way it's designed to be. One thing I found when I open the hood is that the smaller one starts to work when I switch the contact housing from the larger one to it. Always, only one fan is working and it goes with that specific housing.
I have two questions,
1. Do I need to go VW dealer and check what's happening? (I tried several repair shop nearby and they know nothing about VW touareg, espaciall it prob came to be a electrical problem)
2. Is is a problem of battery? If the new battery I got is still not good, what is the right one to put in. I saw people recommending Odyssey PC1350, but thats a lot more expensive.

Over the last few weeks, I'd been smelling something. Today, I realized it must have been coolant. Today, my 225,000 mile, 2.3L 4cyl 5spd 1990 Camry started blowing smoke. When I parked, and gingerly touched the radiator, it was cool -- and empty. When I squeezed the upper hose, it crackled as if very dry. I drove the car about a mile and parked it at home.
When it cooled, I confirmed the radiator is empty -- except for a lot of reddish crud. A hint of the same reddish color on other engine parts MAY be from coolant spraying under the hood, but I'm not sure.
I couldn't tell from spots on the garage floor whether the coolant had leaked out there or not.
How should I proceed from here to address ... a) the leak, and b) any other damage caused by running the car dry?
I have a 08 2.0 CRDi and my radiator fan runs constantly on high as soon as the key is turned on and stays on high until I turn the key off. Have found the fan controller and wondered if that might be faulty but don't wont to replace it for nothing. also where is the temp switch is on the engine or radiator?
View 12 RepliesThe radiator fan on my '11 Escape only runs on high. When the car is cold, the radiator fan does not come on. But as it warms up, the fan does seem to come on at the right time. But when it does, it is pretty loud and runs very fast. I assume it's running on high, because I don't recall whether or not there is a low. Both fans appear to be running, so I'm thinking both fan relays are good. Perhaps the main relay (30C) has gone bad?

View 3 RepliesMy son's 2001 Dodge Neon tends to run hot. The radiator fan comes on while the engine is running, but does not stay on when the engine is turned off, even if the temp indicator is in the range where the fan should be on. Wiring diagram looks like the fan control relay only works when the ignition is in ON or RUN, which would indicate that this is the way the electrical system is designed, but that seems weird...I thought the fan is supposed to operate even if the engine is turned off. We have already replace the thermostat.
View 2 RepliesOver the past month I've notice the idle speed increasing. Yesterday I had to turn the idle adjustment screw to lower the idle speed, as the high idle speed was making it difficult to drive in stop and go traffic. Especially if I took my foot off the gas while in gear, it would jerk rather than slowing down smoothly as it used to. I think the jerking was related to how the ECM stops the injectors completely when slowing down in gear, to improve mpg, then before the rpms gets too low, fire the injectors back up again. Anyway, lowering the idle speed with the adjustment screw fixed the jerking problem, for now.
But in 20 years, I've never had this occur before. The only time I've fiddled with the idle adjustment screw was during tune-ups, and then only had to adjust it 5-15 degrees. This time I had to turn it in 45 degrees. I expect there is unwanted air getting into the intake manifold somehow. And it will probably get worse. Here's some ideas -- in order of most likely to least likely -- I've had what could be causing it.
Throttle valve sticking in throttle body and needs a cleaning.
Throttle linkage needs a lube.
Canister purge valve is open during idle and allowing fumes from the canister into the intake manifold, when it shouldn't be.
Throttle position switch has failed.
Vacuum hose or device leaking.
IAC valve (part of throttle body in this car) is sticking.
ECM is bumping the idle speed through the vacuum controlled actuator (VSD). Unlikely, b/c the idle speed still increases when I turn the headlights on or I turn the steering wheel, both of which use this mechanism (I think).
Thermostat -- unlikely as it happens even when the coolant has reached 195 deg F (when the fan turns on).
1990 Corolla 4AFE - 4cyl , auto, running well...without prior symptoms, now starts (4-5 times) and idles roughly (no moisture in the air) ....seems to me to be fuel..... I know it could be many things - but i have to travel to the car ( not much time last night) .....It doesn't rev clean, sounds choking and very slow especially in drive/rev....not as sharp misses. Start with the fuel filter ? Can the fuel pump go quickly ?or does it go slowly. injectors? I'll check for coil arcing tonight, and the strength of the exhaust (Cat is 23 yrs old.....Vinny?) IAC? ..... Dist cap, wires and plugs are good...
View 4 RepliesOn my early 90's Corolla, when I turn the key to "on" but don't start the engine, the fuel gauge will -- for example -- read 1/4 full. It will stay at 1/4 indefinitely as long as the engine isn't running. Then when I start the engine and drive the car for a few minutes, I notice the gauge has gone up, so it will be reading 3/8 full within 5 minutes of driving. And I don't have to be moving, once it gets to 3/8, it says at 3/8 whether moving or idling at a stoplight. It has always done this, even since the car was new. It's not a problem, but I've always been curious what causes the fuel guaue to rise like this.
View 9 RepliesMy 1990 Toyota Corolla which I hate to retire has only 64,000 miles on it. Starts and runs but while I am driving the dash lights up and the engine shuts off and won't restart. He thinks it is the NEC (?) switch but he said he is not really sure. Spending all that money and then finding out it is not fixed would not be worth it. It also is dangerous what if I am on the expressway?
View 19 RepliesEarly 90's Toyota Corolla.
I've been hearing this sound the past couple weeks coming from the rear of the car. Not related to the rpm, only occurs if the car is moving slowly -- like when I'm driving in a parking lot, looking for a space. Occurs when turning, even slightly, but not when going dead-straight. It it intermittant, seems to occur more often on hot afternoons, never heard it all winter, or even now in the morning. Not that loud, but noticeable. Sounds a little bit like a vibration, sort of a buzzing sound, but more musical than a simple buzz.
The best way I can describe it is that it sounds almost exactly like that sound they make in kids cartoon shows on Saturday morning, when something bad happens, like one of the characters get hit on the head with a baseball bat ..." waah waah waah" .. sort of like a muted trumpet or muted trombone.
Rear wheel bearings? Brakes?
I have a 2000 Corolla with about 147,000 miles. At idle it runs very rough, but can accelerate up to about 50 mph. Then it starts to cough and wheeze and run roughly again and won't accelerate any further. It feels like the engine will shake itself off its mounts, so I slow down and stay under 50 mph. I replaced spark plugs and a repair place hooked it up to a computer. They then told me it needed about 1800 dollars worth of repairs to replace the valve cam I think they said. I'm skeptical and wonder if it just needs a tune up, . It has not had one since I bought it at 128,000 miles, and II don't know how long it had been prior to that.
View 5 RepliesWhile driving our 1990 toyota corolla (3-speed automatic transmission) on the freeway recently, the car gave a slight jerk, at which point my husband looked at the gas gauge and noticed it was well below "E".. Oops. fortunately, there was an exit right there with a gas station. Filled up and we were off toward the next on-ramp. Got to about 35-40 mph, and all of a sudden the car literally just stopped moving forward after violently jerking back and forth several times. We then tried to put in neutral and push it to the side, but it wouldn't even do that. Everything was locked up, seized solid. Somehow we managed to get it to the side.
The flatbed tow truck took us home, and all we could do by that point was move a foot or two in reverse after it dropped us off... fast forward... After several days/weeks of it sitting around we can now actually drive it forward! reverse! but we haven't taken it out of the driveway to go more than 5 mph.. We had seen some fluid leaking prior to this incident, but could NOT figure out where it was coming from despite checking obvious fluids meticulously every couple of days. A friend said it might have been the diff fluid? We'd like to fix the car, but to repair a tranny on this old car (although it only has 67K miles!!!) is too expensive. My husband wants to make it a weekend project.
I'm wanting to know if the hoses are the same?
i assume they are but never seen the under hood of a 10.5.
I was driving my car today, and I stopped at a stop sign. When I went to go, I pushed the gas, and my car revved up, moved forward, then all of a sudden it made a loud grinding noise (Like I was dragging metal sheets), and the gas stopped responding (but the engine was still running). The car still turns on, but whenever the gas is pushed, it doesn't go and makes that awful noise. What could be wrong?
