Golf IV / Jetta IV :: 2004 Overheating - Radiator Cracked And All Coolant Leaked Out
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?
Golf IV / Jetta IV :: 2004 GTI 1.8t Started Overheating - Little Steam Coming From Coolant Overflow Tank
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.

I have a 04" GLI and I was thinking about doing a coolant flush. Looks like I have a slow leak. I was wondering where should I look in order to stop the leak. Put some coolant in about a month ago and now the coolant light is back on. Every morning when I pull out of my driveway there is a small leak under the driver side of my car. Is this an easy fix? If I do decide to do the coolant flush myself what is the recommended coolant replacement?

I've got an '04 1.8t jetta with 158k on the clock. Recently noticed I have a coolant leak on the passenger side of the car. Started the car in my driveway and looked for drips and found coolant collecting in the front valence right underneath the intercooler. Took a look from the top and noticed the hose going into the bottom of the part shown in the picture is leaking like a sieve. It's the metal canister-type thing on the passenger side right next to the radiator. What part this is? And where I can get a new hose that connects to the bottom of it?

I have coolant leaking from the bottom of this hose on my brothers car. I am not very familiar with the BEW's as I drive an ALH. Just looking for info about part number or name on this hose so I can get a new one. Has a part number MH3364 on it but that is not working anywhere.

2004 Jetta GLI 2.8 ... Tonight I started getting a coolant leak somewhere on passenger side. There is also a loud noticeable ticking coming from that area but it is NOT the engine. Slow steady tick, just to the left of engine (when looking head on). Car also began to overheat. Coolant reservoir is full, too flow to be honest, but I don't see any leaks from there. No check engine light is on. Car does NOT leak coolant when off. Only when running and putting load on engine. At idle I cannot see any leakage. Thoughts? I'm thinking perhaps water pump? 87k on the car. Original pump from what I can tell. Bought the car a week ago.

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.

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).
Golf IV / Jetta IV :: 1.8T AWP GTI Overheating - All Of A Sudden Coolant Starts To Flow
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.
Golf IV / Jetta IV :: VR6 Overheating / Coolant Warning Light Came On When Car Idling For 10 Minutes
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.

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 ....
Golf IV / Jetta IV :: Overheating - Coolant Spraying Everywhere Causing White Smoke Under The Hood
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.
Golf IV / Jetta IV :: Coolant Leak From Behind Thermostat Cover So Soon?
02 Jetta 2.0L that I changed the thermostat. o-ring, and cover on when I first got the car about a year and a half ago.
I see dry g12 coming out from behind the cover and my coolant bulb had dipped quite a bit in recent weeks requiring a refill. What is most likely the problem here in such a short period of time? I've only put like 10k miles on the car in that period. O-ring couldn't have seated wrong because wouldn't the problem have been apparent immediately back when I did the job? Maybe I need to re-torque the cover? Cracked cover?
Golf IV / Jetta IV :: Coolant Leak - Blown Motor?
My car has been leaking coolant as soon as you put it in from it looks like the transmission area. Today I filled the car with water and drove it on the interstate to work. The car started getting jerky like it was losing power. So I pulled over and when I did the car shut off. There was excessive smoke under the hood and after removing the oil cap, smoke coming from there also. Tried restarting and it sounds like it just spins. No start. Looked at the timing belt, it's still intact. Put a wrench on the crank pulley and it's turning. What's wrong? Is it a goner?

I noticed today when I was in a drive thru that ,y Jetta was smoking a little.... Went home ate my food and came out and looked underneath the Jetta and found a substantial coolant leak..... My heater core is bad I know this already... Would this cause coolant to leak outside the car or the carpet only??? I jacked up the car and checked for leaks... There is coolant all over the rear engine mount... And the driver side corner of the engine is pretty soaked in coolant....I can't pin point the leak..... There is a connection coming out of the side of the head that's got a little pinky crusty stuff on it but I can't see anywhere around it...
