Touareg :: Radiator Fan Runs After The Engine Is Off
Mar 25, 2016
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.

My 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.

My 2005's fan runs loud and strong for an extra long time after the engine is off. What is wrong?

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)?

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?

I 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!

The 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?

I start the car, with AC on, radiator fan starts and within a few minutes the engine radiator fan stops working, idles rough since the AC compressor pump keeps cycling on and off and engine starts to overheat. After shutting down I check the engine cooling fan fuse and it sure enough is blown.
How do I determine as to where the short is? Is the short in the wiring somewhere or can the actual motor short out?

Not really sure where to go with this one. Was going to start with the fuel filter but I am not sure where it is at?

My 04 Touareg V-6 will start, but will die about 10 seconds after or if I give it gas. I'm pretty sure it's one of the fuel pumps just not sure which one.

After several checks and resets , my Touareg clocks are fast by about 2 min/week. No other electrical problems. Not a known problem with my dealer. Clocks aren't hi-tech ... MFI may have clock module- seems overkill to change it.

Believe an engine temperature sensor is bad. I took it in to get a code read, and they said it could be either temp sensor or fan switch, but didn't know which one without newer software.
Codes are
19537 - Engine Temperate too Low
P3081 - 008 - Implausible Signal
I've checked the fuse legend to see if there is a fuse I can pull, but none of them marked fan seem to kill it after the car is off, so that I can save some battery power.
I believe that I have narrowed it down to the engine coolant temperature sensor. What is the level of job this is to replace? From a parts location manual, it looks like it is in the Thermostat housing, but I'm not sure where that is.

I have had my 06 for 4 months now. I started to get a cold running problem now that the temperature is falling below 40. When I start it in the morning I wait till the idle comes down before driving. I start driving and it runs rough as if it had a choke stuck closed. I spoke with the dealer and he told me to run lower octane in the winter. That has not worked.

I have a 2013 Passat TDI with remote starter, when I start the car it runs until I unlock the doors and then the engine shuts off, I know there is something I am doing wrong but can't seem to find the information in the manual on how to keep the engine running.

92 Toyota Pickup (22RE auto). New block, rebuilt head, new water pump at 300k about a year ago. Sounds strange I know but that's what seems to have happened. Ive never been able to get heat from the truck since Ive owned it so Ive been trying to fix that. I flushed the coolant out and replaced the tstat. I brought the car to a mechanic and he put a pressure tester on the cooling system and he said it wasn't holding any pressure. He also pulled off the heater core inlet hose with the truck running and no coolant was coming out. He thought there was a blockage somewhere but how to fix it. I figured I might as well try replacing the old radiator cap with a new one so I did. Once I did this, the first time the truck went out, it overheated and the radiator crimped upper seam (on the plastic) burst outward.So all in all...something is wrong.

Well I did it, moved Prius out of garage to drive, working on other car when Prius engine starts up runs a bit then stops. You should have seen the look on my wife's face, she just kept looking a me for a reason it would do that. We are still learning a lot about the Prius and she thought it may be normal. I started to tell her some high tech lie but decided to fess up and admit I had forgot to push the off button.

I have a 2005 Hyundai Accent, GLS, 3 door, Standard trans, 1.6. The only factory option above base is A/C.
About a month and a half ago my engine was running hot, one day the temp was climbing and then just dropped like it had been doing for a few days. This car has never run hot before. The next morning before leaving for work, when it was cold, I removed the radiator cap to check the level and it was at the top and the reservoir was at the correct level. After that it never ran hot again. I had the dealer flush it and new cap and thermostat, no overheating problems.
Last week on the way home all of a sudden the engine started running at 6000 rpm, I thought it might be the 3rd party cruise I had install when I first got the car opening the throttle. Had it towed home and the wrecker driver was watching under the hood as I started it again. The throttle linkage remained in the closed position, the engine should be idling but it ran back up to 6000 rpm again. There was no movement in the linkage. I connected my OBD Scan Tool to check for any codes, there were none.

Here is my question.. 94 Z28 38K 6spd. Starts right up and runs well, for about 15-20 minutes then will shut down( like the key was turned off) When this happens I have no signal to either the ignition module or to the injectors.
This car was damaged by an idiot that flooded the dist. with coolant doing a flush. They replaced it with a Advance auto remain. This is when the trouble started. I did replace the I/M with an AC OEM Module, no change, verified all wiring from the computer to the Dist. and I/M. All checked out. I am thinking that the cheap remain unit is my problem and am looking to get the MSD Opti spark system to hopefully fix and to prevent this problem from happening again.
I cannot retrieve codes (94 won't flash CEL codes). Is there any other method of diag I could use to verify my suspicions. Oh, there is not response from the Tech either once the engine dies.

I tend to think my wife's 05 Prius gasoline engine runs too much. The engine cranks up when just backing out of the garage. It starts backing up totally on electric motor but when I stop to make sure the garage door closes the engine starts.
I see the same thing driving through the neighborhood, driving a steady 35 mph with batteries well charged 50% of the time the engine will run.
She is getting average 45 mpg.
