Golf IV / Jetta IV :: 2004 Overheating - Radiator Cracked And All Coolant Leaked Out
Jul 30, 2014
Ok so I have an 04 Jetta 2.0 and lately it's been overheating on me. The first time it started overheating was because my radiator was cracked and leaked out all my coolant, I swapped the radiator everything was fine for a while. The second time I started overheating, I saw my primary fan was bad it wasn't spinning at all, I swapped it everything was fine for another while. I also changed the coolant temp sensor, it wasn't bad it's just because the coolant flange was leaking coolant, so I changed it a long with the O-Rings and sensor. I also changed the thermostat just incase that was the problem but it wasn't.
I don't think the fans are turning on by them selves when they have too, but either way the car still overheats when I turn on the fans manually with the A/C. I'm not sure if the coolant is circulating, as the car only begins to overheat when I come to a stop and it idles. I have a feeling it's the water pump but I wanna be sure it is before I change it. What it could be? Things that I should check for that usually go out?

I have a 04' RX 330 with 92k. It has small radiator leak. If you are standing in front of the car and look below the fan on the left side of the radiator you can see a small amount of red fluid that has leaked out of the radiator. However, the leak isn't big enough that I ever have to add coolant I just top it off when I get the oil changed. Also it doesn't puddle on the pavement when parked.
The only thing I really notice is that my windows tend fog abit easier now so I assuming the moisture must be making its way into the ventalation somehow. My mechanic said its about a $700 repair. My question should I fix it and is $700 reasonable. Also I've never had the timing belt replaced would it make since do have this done at the same time as the radiator. How long will it take before it becomes a major problem instead of a minor annoyance?

First off new jetta owner. I changed the thermostat. There is no heat coming into the car upper radiator hose hot lower hose is cold & seems there is no pressure. I bought the book to repair the car but it doesn't give me troubleshooting directions other than it might be the water pump or a blockage in the radiator.

I have a 24v Vr6, a couple days ago i spotted some water on my garage floor. I looked in the engine bay and I saw some coolant on this metal can looking piece, it's on the passenger side of the car to the left of the headlight door and a couple inches down. I also looked all the way at the bottom of the engine bay on on the plastic shield there is quite a bit of coolant that has leaked onto there.

My 04' GTI, 24v VR6, all stock, @ 107,000. I had a coolant leak from the t-stat housing. I installed all new housing, seals, and C-Pipe from GruvenParts. Already had a green CT sensor installed and the kit I got didn't come with one, so I didn't change it. Found out the leak was from the t-stat housing o-ring didn't fit the old housing. The new one fits perfect. I put coolant on the seals and burped it. Doesn't leak a drop. But still overheating, all the hoses have pressure and are hot, so no blockage....I noticed the fans were not coming on at all. The fans used to engage every other minute and run for 15 secs on high ONLY. Longer times, if not constantly w/ A/C on. I was wondering how to test the fans, sender, and/or fan control module to see which one of them isn't working. And which pinouts are what?

I have an 04 gti 1.8t and last night it started over heating. I pulled over and checked the coolant and the oil but everything looked good. I let it cool down and drove it home. When I popped the hood there was a little steam coming from the coolant overflow tank but I saw no leaking. I decided to vent the pressure off the system and then I got a little drip on the passenger side close to where the inter cooler is. I can't pinpoint the leak though.

Today, the air conditioning stopped working in my 2003 Elantra. Just stopped blowing cold air. Then the engine thermometer kept on climbing. When I pulled over home, I lifted the hood and heard a lot of bubbling and gurgling sounds, and coolant fluid leaked out underneath the car.
What could be the cause of this? When I let the car stay for a while, the AC did kick back on, but only for a few moments and the thermometer kept on climbing again until I turned the car off. The fan is blowing, I can hear it, but it is obviously not cooling the engine off appropriately.

I 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.

Mk4 Jetta Gli 1.8t , car was over heating only when sitting 5+ minutes at idle, mechanic said the big fan needed replaced so he replaced it. Car still over heated so i replaced the coolant with G13. It hasn't over heated yet but got in the car this morning and the coolant light started flashing and car was telling me to STOP the car. Checked out the coolant and it was on the low side. What it may be? Leak somewhere? Bad thermostat or water pump gone bad? Timing belt and water pump were done when i bought the car when it had less than 50k miles, car now has 99k miles on it.

Recently I started leaking coolant on the driver side area to the right of the engine:
I am assuming I need to replace some part/tubing that has a leak in it, but I am not sure what any of these things are called. How to identify what leaking part here is?

Last night while i was driving my car began to overheat. I could smell coolant burning. I pulled over and opened my hood. The coolant inside the coolant pod was boiling. Some coolant lines were steaming as well. I could also hear a gurgly like noise coming the engine. This is a 1.8t gti

After finally getting some issues sorted this weekend (needed a transmission flush) I was driving around a bit to make sure everything was good. On the way back to my house, the car started overheating. I replaced the thermostat this winter (~4-5 months ago) because it was stuck open making things run a little cool.
I was thinking the water pump is probably shot but not 100% sure. the radiator fans both work and when I turn on the heater, it blows hot. Any good way to check if the water pump is dead? I have a little point and shoot infrared thermometer and one side of the coolant line was way hot and the other was fine (cold ~90 deg F).

I am having a overheating issue with my 1.8t AWP gti, it goes as fallows, start the car, engine warms up go for a drive (short 5-8 mi), park the car and temp gauge starts to rise, (turns off car)... I began to check some things with the system, I checked both rad hoses bottom is hot top is a bit hotter and fans work when ac is on; here is where it gets interesting i took off the coolant return hose on the reservoir (cold start) and nothing was flowing ...water pump?... So i turned the heat on and air full blast and all of a sudden coolant starts to flow.
It also seems like air is being spat out as well. Soon after the flow beginning my coolant in the reservoir starts to fluctuate (rising and dropping) with air bubbles and beginnings to over flow so i shut the car off. Now I know what the possible issues are its either the water pump, air in the system or bad autozone thermostat. Here is some history of the car TB was replaced at 70,000 by Previous owner, i bought the car had the belt inspected and was told it was good, about 2 months ago i had a coolant leak and had it misdiagnosed as a thermostat housing leak; it turns out it was a coolant bypass hose that was leaking so i ended up fixing it. I lost a lot of coolant but topped it off with g12+. My mechanic doesn't think its the water pump and recommended changing the thermostat for an VW one another mechanic recommended to bleed air of the system.

Before I go buy a Bentley manual to dig around, when should my radiator fans kick on. I had the car idling for 10 minutes, no ac or heat on, and my coolant warning light came on, it overheated. It already has a new fan switch in the radiator, and the fuses are good.

A bit over a week ago, I posted about a major coolant "spew" in my shed.

So I was going to change the oil today and noticed that there was coolant that leaked all over the engine. I don't know where it came but I washed it off (should have snapped a pic!), so today I will try to drive around a bit and pop the hood again to see where it is coming from.
I'm guessing it leaked from one of the hoses or something. I recently got everything changed (timing belt, water pump, new radiator) about 3k miles ago or so.
I took her offroading earlier in the week two days in a row as well and went through some rough terrain in 90+ degree heat.

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 2002 VW MK4 1.8t. It has 172,000 miles on it. Since i bought the car i have had to add coolant from time to time due to leaks from various plastic coolant parts so I replaced the crappy plastic connectors and flanges as they failed but it has never overheated till a couple days ago. It rose up to about 210'F but I didn't let it get to 260'F (aka the red zone).
While the temperature was up, the coolant was spraying everywhere causing white smoke under the hood. I stopped and looked under the hood and came up with the conclusion it was the coolant flange that holds the temp sensor since it was leaking coolant from the flange like a faucet hince the reason it caused it to overheat due to lost of pressure and no coolant in the system. So I replaced the part and gaskets then checked for other obvious leaks.
No leaks are shown nowhere else in the vehicle. So I added coolant to the car and let the cooling system do its magic as i left the heater on high. Let car idle with cap off and heater on for about 45 minutes. No signs of overheating. So I take the car for a spin and that's when the car starts heating up. I look under the hood and feel hoses and notice all are pressurized but top hose that leads to coolant flange is hot and the bottom hose connected to thermostat is cold.
I checked the return hose that leads up to the coolant reservoir to see if it's cycling and it appears it was. At low rpms the return hose had a steady flow and at high rpms it was flowing much rapidly. Which made me think it wasn't the water pump also this car with that many miles wouldn't have lasted with the plastic impellar this long if it wasn't already swapped out by previous owners. My question is what would cause it to still overheat? I forgot to note the fans did not turn on when the temperature was rising unless i turned the a/c on. But i still did a drive test with a/c on and it still overheated. I also did multiple burp cycles. I have invested alot of money in custom work and suck to leave it parked on the drive way.

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?

My 2000 Accent with 164,000km is not overheating but is dumping coolant into the reservoir so that the radiator is about a quart low. I did have a few problems with it overheating in the past month, but that was solved by thermostat removal (always above 80F here). I stopped before the overheats reached the redline and allowed the engine to cool before continuing, no known adverse performance during the overheats. No water in oil.
Failed troubleshooting:
Drained and replaced coolant x3
New radiator cap
* No thermostat.

My washer fluid leaked out of the bottom of the reservoir and I would like to pull the fuse because it keeps beeping it is low. obviously. I do not have a rear wiper as it is shaved so #27 fuse is out and I was wondering if I pulled # 24 if that would stop the damn sensor or if I can pull something else, maybe just unplug it from the reservoir. I find myself using it never so I wont be fixing it anytime soon.
