You think something's wrong with it? It's not on always, but sometimes it switches on right after I start the car and apparently doesn't go off until I turn the car off. I can tell you the car doesn't really warm up.
View 19 RepliesI 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?
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.
View 2 RepliesMy radiator went the other night, just after i took my car in for a 20k service. My car has 19k miles. Obviously things like this shouldn't happen. Regardless it's in the shop being fixed.
View 10 RepliesI have noticed that the driver's side radiator fan (big one) is not working at all. when I switch the A/C on, only the small fan is running.I'm getting the below errors

I can move the fan by hand and it's not jammed. What to check ?
So there was a thread on here a little while back about the radiator fan running after the car is shut off and I noticed that I have never heard my radiator fan run after I turn off the car, even when it was 100 degrees here. I do notice a high pitched electrical sound from under the hood that sounds constantly for several minutes after the car is shut off. Is it possible that these two things (radiator fan not running after shut off, and high pitched sound after shut off) are related? Is there any simple way to maybe test to see if the fan is functioning via VCDS or something?
View 6 RepliesI have 2011 GTI 38000 km on it.
so I understand radiator fans run up to cool turbo on a hot day after shutting off the engine.
It was 32 degrees out yesterday but I didn't hear any fans running except high pitched electric motor sound.
I'm worried about if there is something wrong with the fan... I hate to go to the dealership because they will charge me 70 dollars
if they can't reproduce the problem.. doesn't matter even if you have warranty.
Both fans run when Engine is on and A/C is on with low speed.
I've parked my R32 mk4 over 5 years ago and recently I started the engine and I noticed over heating and then noticed there is oil coming out of the radiator water reservoir / it's thick and brown !!
I thought about it and went full overall opened the whole thing the head and pistons and everything and I couldn't find any traces or anything broken ,, (I wanted to do that since a long time).
I hit a hunk of concrete on the way to work earlier this year and have a cracked radiator. I am looking to replace it with something better if possible. I searched the threads on here and the results seemed inconclusive. Looking for info regarding actually installion of these radiators in car? If so, how'd it work out?
View 24 RepliesSo my radiator fan isn't working my ac fan is but not the other one. I knocked on it a few times and got it to spin? Also I was wondering where I could buy silicone hoses for the cooling and for my turbo the hoses i think have holes that's why the check engine light is on something to do with vacuum leak/high idle.
View 1 RepliesNoticed fan running noise this past week with AC on or off--more noise with AC on. Dealer diagnosed dead small fan, and the large fan was compensating for this condition.
View 1 RepliesAs it was such a matter of time, my fans on my 24v gave up during winter, no big deal as it was a pretty cold winter but now that spring is around the corner, I gotta fix this issue. To they change for the same OEM unit that will die in the next 30k miles.
View 3 RepliesSo last night I noticed that my radiator was really loud. It sounds like it's working really hard. Also, when I turn off the car the radiator still runs for a few seconds. Heck, it may not even be the radiator as I'm not 100% positive.
Here's a video of it. In the video you can see that the noise is louder than the engine. Around the 24 second mark I turn the engine off but the noise still persists for a few more seconds.
I didn't rev the engine as the sound doesn't get louder or quieter based on my RPMs. Brought it to the dealership today. Service writer tells me it's because I did the flapper mod.
Realized I was leaking coolant from the front passenger wheel well and bumper area. If I fill up the expansion tank it'll almost empty in about 2 days of sitting. Took to the stealership for a quick diagnostic and they said my Intercooler...(Auxilary Radiator) was leaking at the hose connections and will need to be replaced as well as the hose. I can't find a good DIY on this at all and I'm not sure which hose is connected to the Aux Radiator. So I'm wondering which hose connects to the Aux Radiator? Is there anything else I should replace or look for while I'm at it? Which hoses connect to this Second Radiator?
View 2 RepliesDon't drive my R every day these days. Recently had to get it out and get it smogged when I noticed there is no AC. Turns out the aluminum AC line next to the radiator clip on the passenger side has a hole in it. It has been vibrating against a screw head which finally drilled a hole through the line.
I heard the "ticking in the dashboard" sound.
So this seems to be a common code that is thrown when you near 100k miles, I'm at 77k .. This thread seems to be the most organized [URL] ....
"Long story short, there are 5 main reasons this problem can pop up, listed in order of likelihood, least to greatest:
1) Coolant sensor
2) Thermostat
3) Bad fans
4) Coolant mixture
5) Water pump "
My issue is that the only ones I'm (probably) able to rule out is coolant mixture and bad fans. My radiator fans do turn on from time to time, so I thought I'd ruled that out (unless it would throw a code for not turning on at appropriate times?)
I heard of a test to turn on your AC and see if they turn on, but my AC hasn't blown cold air like ever, so I don't know if that affects the test (probably not?)
A couple years ago I had a shop replace the original thermostat with the new one, or was it the coolant sensor, or both (ugh, I don't remember!) That leaves thermostat, coolant sensor, and water pump.
I guess my main question is is there anyway to find out which it is between these 3, without spending so time, money, parts etc? It doesn't seem the coolant sensor is easily accessible for one.
My car has been really slow recently but I also need to change the spark plugs, I'm doing that this week. I cleared the CEL/P2181 code and it returned a few weeks later,
I'm starting to change my mind about this car being easy to maintain/reliable, I'm always on time with maintenance and with only 77k miles on a 2004 car.
I don't understand what is going on I noticed smoke coming from my fans radiator fans and I'm pretty sure that it was motor being fried I've gone to the junkyard and bought a used assembly hooked it up and still nothing could be a possibility that when the motor fried it fried the control module for the fans
View 1 RepliesI just replaced my radiator in my vr6 jetta. I've replaced my coolant before, with this same problem,but it never affected anything and did not find any answers. But here's the deal. It filled with about 2 gallons of mixed coolant. No noticeable air bubble sounds, coolant flows back into the reservoir. I opened my top rad hose and poured coolant in also. It is not overheating. My heater is also hot, no problems there. It just seems suspicious that my car takes so little coolant, and runs just fine. I also flushed the system with my garden hose, and let all the water drain out.
View 3 Repliesyesterday my upper radiator hose connector broke off and I replaced it filled it up with coolant and now the upper radiator hose gets really hot at normal temps while the lower hose is cold maybe and gets warm not hot or anything... I see some steam coming off the radiator but i think its all the coolant that splashed on it yesterday from the hose busting off and flooding it basically. the car does not overheat at idle or driving or anything so I am curious to what it could be
View 4 RepliesRadiator fans making tons of noise on my newly purchased gli jetta...
View 3 RepliesLately I've noticed the radiator fan has been running fairly excessively for the entire duration of a trip. (~1 hour) The ambient outside temperature has been around 30 degrees and was driving normally on the highway for the entire trip. (engine temps are normal as well)..
When I shut the engine down and get out you can tell the fan was really working since it takes a good 10 seconds to spin down. (almost like a jet engine shutting down). Still other times, it doesn't do it with the same conditions. One of the only things I can narrow it down to is it seems to always run long when it's the first drive of the day.
