Golf IV / Jetta IV :: 2003 - Weird Coolant Leak - Goes Half Gallon Per Mile
Nov 4, 2014
i have a 03 gti vr6. 24v 6 speed. it started losing coolant the other day. but the thing is the radiator all the hoses and the water pump(s) are all dry. its fine when its cold, holds coolant just fine. but when it warms up its only fine at idle, so im guessing its some sort of pressure related leak. the car goes through half a gallon every mile or so. only the inner fender on the left side is soaked and the suspension components on that side as well.

We have a significant coolant leak. The attached pic is of a coolant pipe which runs down from the rear of the head at the firewall. This was taken from the underside looking up.

not sure if this is normal or not. usually ONLY comes when I turn my car on for the first time of the day. (cold start obviously, keep in mind its cold where i live at this time of year), there is a weird whistling like sound. goes away when the rpm gauge hits 10/ after 1 minute of the engine running. at odd times it will come on again after leaving the car off for a few hours, after work for example. I was told it because I'm using the wrong coolant??

My 2002 has had a slow coolant leak for quite a while (maybe a quart a month). Now, however, I am losing over a gallon a week, but with NO visible leak!
The oil is clear, with no signs of antifreeze in it, so I am guessing the head gaskets are ok. But I am perplexed as to where my coolant is going!
After reading more threads in the forum, (which I should have done more thoroughly before posting,) it seems that I may indeed have a head gasket leak. From what I've learned, that would cause me to lose coolant through the exhaust while driving, and would explain why I don't see a visible leak anywhere. Am I on the right track? Before I replace the head gaskets, are there any other causes that may have a simpler fix??

My 2003 GTI 24V VR6 is leaking coolant pretty quickly from the passenger side of the engine compartment. I have a new water pump in hand. If I'm replacing the water pump, would it be smart to go ahead and order a thermostat and metal crack-pipe to replace at the same time that I'm having the water pump installed? I'd hate to get the water pump installed, and find out that the leak is at the crack pipe.

Here's what I'm dealing with. Took the truck on a 1500 mile trip with no issues. Got home and started it the next morning and it started right up. 1/2 mile from home it starts to run rough and wants to die. It does this for a few minutes and then perks back up and runs fine for however long the trip is. It will always re fire and have no issues. Every morning it's the same game as described above. Within 1/2 from home it's doing this. Seems to be fuel delivery related, but why would it start after sitting overnight, and then after its little fit, run without an issue?

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?

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...

Just purchased a 01 golf 1.8t 5spd and noticed it has a small coolant leak.. Left parking over 2 days in the same spot and it builds up a little puddle.. It's dripping down off of my oil pan and I haven't been able to trace it back to where the leak is coming from..
I've been told it could be my water pump? The car has 92k miles.

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?

My 2000 jetta glx is leaking coolant fast enough to empty the reservoir from full in about 10 minutes but only does it while running. Why this is or what I should look at fixing?

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?

My 2000 Jetta 2.0 has a coolant leak. I searched and found a lot of mentions of the flange on the driver's side, and I have coolant dripping from the bottom of the car in a location that seems consistent with that, but I felt all around the flange and the hoses that are connected to it and it feels dry.
Where else could it be coming from? (yeah, I could jack it up climb under and look, but I haven't had time yet). I also seem to have an oil leak around the same location, but the dipstick tube was cracked near where it went in to the engine so I'm hoping that was the source of the oil.

Had a P2181 come up twice now... both on startup on a cool morning. Came on again this weekend. Monday morning I noticed a small coolant leak under the front of the car directly in line with the passenger headlight, but it only leaks if I park the car with the front down a slope. I parked uphill on Monday night and no leak in the morning, but I backed in facing downhill on Tuesday and had a small leak when I checked late last night.
So, last night I broke out the UV/black light -- G12 seems to fluoresce yellow'ish. I couldn't see much, so it is a small leak. There is some wetness on the bottom passenger side of the rad that's dripping over the back side of the front bumper/lip. No wetness around any other hoses, thermostat housing, temp sensor, turbo lines. But that's all from the top view. No time yet this week to get it up on stands to pull the bumper/splash shields for a closer look either.
I am little concerned tho as there's some wetness around the valve cover and when I pulled the oil cap my eyes suggested a bit of fluorescence under the cap and inside the valve cover. I'm a little worried oil and coolant may be meeting up somewhere... And to think... I was just in the process of getting geared up to do brakes and plugs before getting a modest tune (stage 1).

So the car broke down on my wife while on the way to work again. This time the coolant is completely drained from the system. It is all over inside the engine compartment so it's impossible to tell where the leak actually is. Within the last year we have replaced the pump and thermostat so I am going on the assumption that neither of those are an issue at this point.
Although I figure a stuck Tstat might cause too much pressure to build up and blow a line. Ill cross that bridge when the time comes. I also assume there should be nothing wrong with just putting water in there just to find the leak and then of course draining and putting the proper fluids in. Is this a wise course of action to take? You never know with these German things. I would of course use the same type of water that is used to mix with the coolant already.
My wife also stated that she did not see any smoke coming out of the tailpipe and only the engine. This means the engine itself should be safe and no gasket blew inside.

My car is a MK4 1.8t 2001 model.
Recently I've been losing a decent amount of coolant, and I noticed a puddle of water forming up right in front of my front right tire. I've inspected the engine bay, and the water seems to be coming from beneath the coolant reservoir itself, and forming a puddle under the windshield washer bottle. Which ends up dripping under the bumper in front of the right tire.
I didn't have any time to do more inspection, not even to take pics. The car is left at home as i don't want to drive it while it's leaking. Where to inspect or which parts to take off in order to spot the leak... No overheating has occurred, yet.

My son was driving his 2001 jetty vr6 2.8 he said he heard a pop and then coolant was pouring out underneath. Radiator and hoses look fine reservoir too.it pours out as fast as you put it in. When underneath it looks like it's coming from an area to the right of the oil filter towards the belt side but not ask the way over by the belts more like the middle of the engine. I can't see anything from above just dripping from below. I am hoping not a head. Oil look good no coolant in it and doesn't smoke.???

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?

So my coolant system woes have continued! I recently replaced my thermostat ,thermostat housing, thermostat cover and all of the rings and gaskets. I finally stopped the leak on the driver side which seem to be the thermostat now about seven days later I am experiencing leaking on the passenger side. I walked out from work today and noticed I pool of coolant under the car. I can't tell exactly where it's coming from but it's coming from one of the components that runs off of the large belt. I snapped a few pics from the bottom of the car I don't think this is the actual component that's leaking. I think the leak is just falling off of it . I was wondering where the water pump is located.

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.
