My brothers jetta is over heating constantly. The thermo switch on the radiator and controller box under the battery have been replaced. The fans dont come on till just before the red mark on the gauge. There are no water leaks, and we can hear gurgling when running the engine. How can we tell if the water pump is bad or not and where is the thermostat if it has one.

View 8 RepliesSo yesterday, my car started overheating, not when i'm driving, but when it's idling, then when i turn my heat on, it goes back to normal.
View 3 RepliesI am having a weird overheating issue, it usually happens when the car is idling, and cools down when i start to drive the car again. What could be causing this problem.
View 9 RepliesSo I noticed one day when I was standing outside of my car right after I had turned it off that I could hear the coolant bubbling some. I had just recently flushed the coolant, put on a new water pump, thermostat, and put in a new reservoir with a new cap so I figured it was just some air in the system because there was air in the top radiator hose. So I just worked the air out and thought that was it. The next time I drove my car it did it again and there was no pressure release when I took off the cap either. I ended up getting the head worked on (valve job and check the head for warping). Even after all of this my reservoir doesn't seem to build pressure and every time there also seems to be air in the top radiator hose. After the car is warm I can work coolant back in the hose and 5 minutes later theres air back in it. I've pretty much replaced everything with the cooling system besides the hoses within the last year so I don't know what it could possibly be.
View 2 RepliesCar was running fine on friday when I left for detroit, it sat in my driveway all weekend, but on the way to work this morning I get a warning light to STOP and my temp gauge is right below 260. It took about 10 miles for the light to come on and the car does NOT overheat while idling. The car is only at 52k and I have not replaced the water pump/timing belt yet.
View 13 RepliesWas driving home yesterday from work and the dash light up saying the car was overheating. Was too dark last night to look at everything so this morning I checked all the fluids and everything was OK.
Drove around the block a few times and noticed when starting the car the thermostat said normal temperature (straight up) even though it was cold, then climbed into the redzone, dropped to zero, then shot back up into the red. the upper radiator hose is hot so fluid is flowing.
Thoughts are bad water pump, thermostat, or blown head gasket after going though my repair book. Not sure how to check any of these. Also ran VAG and nothing came up.
So just for a little bit of a background, I have an Imola 20th with 165k miles on it lowered on B&G's, stage II+ unitronic w/ Franken turbo setup.
I've been running into some issues with the ride as of late, well, more than usual, and I can't seem to figure any of it out. First, the car kept overheating even when it wasn't warm outside after driving for only about 10-15mins. Took it to the shop, and they said that the fan & fan motor died on me and so they replaced that and the blower motor resistor, but then a month later I was back at the shop getting the fan replaced again. A month later, I was at another shop getting the fan switched, and not even two months later I was back at the original shop having the fan swapped out yet again because the previous one died. It's been a couple weeks now since the last fan being switched out and I'm starting to see some overheating issues yet again when the A/C isn't turned on and blasting. That's problem number 1.
Problem 2 would be all of the dash lights that randomly keep coming up; the traction control and ABS lights have been on for about three months now. Just last week the dash light for the airbag came on, and then today the light stays on for the door saying that it's open but the interior lights don't stay on like what's typical seen when the door is open. Also, every now and then when I start the car up the brake light will flash/beep a couple times then stay lit the whole time I'm driving around, but when I turn the car off then turn it back on again the brake light isn't lit...the airbag, ABS, traction, and door lights are still lit. I plugged a reader up to it, and no codes are showing and everything says it's checked out. Not to mention, the car has been idling real funny lately, usually sitting at 800rpm's then randomly dropped to around 400 to where the car almost dies off then it just shoots right back up.
I replace my timing belt and water pump and my engine is now over heating. I notice it's only over heats when the ac is running and the engine is idling. When I start to drive the engine temp goes down.
View 1 RepliesMy sister has a 2004 gli 1.8t with 65k. The temperature gauge says its overheating, the cel is on, but the car appears to run fine, the fluid levels are appear to be fine, and you cant see any leaks. Her fiance thinks its water pump issues...
View 4 RepliesI just drove the GLI from pa to myrtle beach for vacation. On the way back I noticed the temp was steadily rising while idling at a red light then at a gas station. Coolant level is fine. Thermostat, water pump, thermostat, and both temp sensors were recently replaced in the last two months.
So I know none of those things are a variable. Both fans never come on. I tried turning on the ac to get them to come on. But nothing. I read as much as I could on forums to find a solution but none applied to my specific problem.
Car is completely stock besides p flow intake. Has 153000 miles I'm pretty sure everything involving fan is original.
I've decided the first issue w/ my new-to-me jetta I want to focus on is the cooling fan constantly running. I suspect this is potentially related to the temp gauge not reading anything, which I suspect might be because of the coolant temp sensor.
So basically, when I turn the key to on (I'm pretty sure it's on, not start), one of the cooling can comes on. It's the fan on the right side as if you are sitting in the driver seat. I've been looking at the wiring diagram for this issue as well, and the only other thing I can think of that isn't a computer involving issue would be the thermo switch. But it seems like both fans should be coming on in that case, and it's definitely only the one fan that is coming on.
I have a problem with my vw jetta vr6, the airbag light is always on. I changed the battery and few days later the airbag light came on. I drove my car to the dealer and they found out that my driver airbag unit has a lot of pressure on it, so they told me that the airbag needs to be replaced.

View 3 Replies2004 Jetta GLI V6 24v 6 speed ... This started a few years ago, but it was happening in 3rd gear only -- therefore I avoided engine braking in 3rd gear all along. The noise was a pretty loud, noticeable grinding/spinning noise. 3rd gear while accelerating or maintaining gas worked and still works perfectly, smooth as can be.
Somewhat recently (6mo-1yr ago) all the other 5 gears started making this grinding noise, some more than others. 1st gear I don't really know because I don't engine brake in 1st. However, 2nd, 3rd, 4th, 5th and 6th (barely noticeable but still there) all make the noise. I now of course avoid all engine braking, however even the transitional steps between gears can be heard sometimes ... unless I perfectly match the RPM etc, but I'm just trying to get to work and back here ...
The car is still quite drivable, but with a major obstacle (pain in the ass) and a new clutch is probably around the corner -- I have 107K on it now. However ... a few years ago when it had 26K on it .. it didn't need a new clutch yet 3rd was still making that noise.
Engine will overheat unless I turn the AC on. The engine fan only operates with the ac on it seems.
Will not overheat unless in traffic for a while.
Would it be radiator thermo switch or the Fan Control Module?
My temperature has been randomly dropping, them back to middle, and recently my engine was overheating because I'm guessing the fans didn't turn on, because I'm also guessing, the engine didn't know it was overheating?
Anywho, during my replacement, I made sure to get rid of the pressure, and the car was cold. I tightened the cap again, but when I took the sensor out, all the coolant spewed out.
Now if I understand this correctly, do I have a leak? I figured the leak I had was coming from the temp sensor as it is.
Here's some pictures for those who'd like to see ....
I have a 2003 Accent and it has been over heating constantly for about 5 months. After it started, we replaced the main radiator hose, thermostat, radiator cap AND a head and head gasket. It worked for about 2 weeks and then over heated again. It seems like there is too much pressure somewhere because the lid for my reservoir shoots off and all the coolant comes out. I'm just not sure where to look for a clog since it is coming out of the reservoir. It also recently started having transmission problems(?) or that is what I think it is... It won't go in reverse and has a hard time shifting sometimes. I'm not sure if it could be related or if it is the tranny also.
View 4 RepliesThis is what its doing... Im starting to feel lost about whats wrong. I start it up and everything is fine. With in about 10 minutes it starts to bubble and spit out a little water then shuts its self off. And the gauge on the dash never reads above 190. And the fans don't come on unless i turn the ac on. And the ac still blows cold. The lower hose stays cold. I just replaced the thermostat and the water pump. But it changed nothing. Im thinking maybe its clogged somewhere. Maybe in the heater core or the radiator.
