Golf IV / Jetta IV :: 2000 VR6 Started Leaking Coolant And Getting Way Too Hot
Apr 28, 2010
So over the weekend my 2000 jetta VR6 started leaking coolant and getting way to hot. So i parked it at work and eventually got it towed to a friends shop. I haven't looked at the car since then so bear with me on the descriptions I'm giving as they are just what he told me over the phone. I'm going to try and get to the shop in the morning to check it out some more. He says I have a leak in 2 hoses that look like they are just rotted out.
First hose he says "Comes from the back of the head and is about a half inch wide. it goes into a Y and then the top half goes into a smaller hose." The 2nd hose he says "on the top of the coolant bottle there is a line that goes across the back of the firewall then comes into a rubber hose and from that hose their is a T going into other places."
Obviously that's not a lot to go on. and when I'm looking at replacement hoses at shops online I'm not seeing ones that match these descriptions really. I've been looking for a diagram or some kind of illustration of these hoses so that i can send it to him and he can figure out which ones they are but I have not been able to find one.

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?

When my 2000 GTI VR6 sits for a week or two the coolant will run low. There are no leaks that I can find. No coolant in the oil. The crack pipe looks dry. Nothing from the thermostat hosing that I can see. The carpet by the heater core is dry. Nothing that I can see. The thing that is funny is I can drive the car with it 100 degrees outside in Georgia and have no problems with the coolant getting low, or any signs of a leak, smoke or smell. The head gasket and every gasket except the oil cooler and oil stand gasket were replaced about two years ago. The heater core was also replaced at the time. I gave the front pulled loose so I can pressure test the system and look more today.

My 2000 F150 started leaking from a small pin hole in the coolant bypass pipe that is located on the top / front of the intake manifold, it is the pipe that flows toward the heater core. I decided to remove it without pulling the intake "being lazy". I almost had it and it snapped, while trying to retrieve the piece that was still in the hole It broke and part fell into the intake, I assume into the head in one of the coolant ports. I have removed the intake and still cant seem to see it or retrieve it. I have tried a shop vac, and a magnet wand, still nothing. While pulling a vacuum I noticed that I had flow / suctions from all my cooling ports on both heads, the line from the heater core, and even my top radiator hose.
So I guess my question is, If I cant get this out and it fell into one of the water jackets in my block will it hurt anything??? I know rust and other things end up in there anyway. I still haven't given up on removing, I am really in need of answers,, in case I cant remove it. I do know the flow of coolant is up through the pipe I was trying to replace, and either through the heater core (hose), thermostat, or maybe the bypass back to pump.

2000 Subaru Outback. The head gaskets have begun to leak slightly (oil and coolant), even though I brought it in for the recall at 80K and the dealer put in the additive. I recently (111,000 miles) put in another bottle of the additive coolant conditioner and the leak seems to have at least slowed to a trickle. Is it really essential to have the head gaskets replaced? Or could I just keep an eye on the oil and coolant levels and put a bit of kitty litter in my garage? Some of the information I googled indicates that the recall of this car is for an OUT leak and not an INNER leak--which would be worse. Is it true that an OUT leak is not as worrisome?

So I bought my 03 golf 2.slow about 10 years ago used and it came with a moonroof... not a sunroof. I never really thought about it and just assumed it was a option from the factory but the seals have been leaking lately and I was looking for a replacement seal and could not find anything only sunroof parts. Is this an aftermarket moonroof where they cut a hole in the roof and added this?..I really hope not. Or did someone take the sunroof assembly out and put this in its place.

Today I had planned on replacing coil No. 5 to rid myself of the rough idling and drive I've been experiencing the past couple weeks. Car is running smooth now, however, I've noticed again that coolant continues to leak at a fast pace on hot summer days.
I've always had a slight leak, about the size of a hockey puck or so if I let it sit over night. But once temps reach in the mid 80s-90s, like today in PA, the leak gets even worse. Pictured below is the amount of coolant that had dropped in about an hour span. I have attached an image and video of where I can see it dripping from. It looks like it may be a hose, but I can't tell if the coolant is just dripping on there initially from somewhere else, and then onto my driveway. I don't have a jack that I can get it high enough to check.

2005 jetta gli 1.8t automatic ( i know flanges are different from automatic to manuel) just recently found the leaking coolant flange. Can I change the flange without having to drain the coolant out of the system. my coolant is new because i recently had the timing belt/water pump etc done so its new coolant and i do not want to flush the system. also will i have to "bleed" the system if i just pull the flange of and replace it if that is possible.

I am looking at a 05 GLI 5 speed with 133k miles. I drove it yesterday and it runs fine, but I smelled coolant after I turned it off. I was told by the dealer that the turbo is leaking some, it was spooling while driving and didn't seem to do anything funny. The check engine light came on and said coolant was low when we got back, when I cranked it back up the light was out. Just not sure about it.

My MK4 Jetta started leaking coolant recently and I'm not sure where it would be coming from. I already checked the reservoir to see if it was leaking out of there but I could not find any leakage. I've found some coolant on the right side driveshaft near the differential, there is also some on the diff. I'm wondering if this could of happened because it has been sitting on a jack stand not being driven for about 2 months. Is it possible that within that time 1 or more of the coolant hoses could have cracked or anything. And while I'm on the subject of why it's on a jack stand, it also has gone through wheel bearings twice within the last 6 months to a year. Is this normal?

Yesterday i was cleaning my car and when I took it out from the garage i noticed a spot on the garage floor. Put my finger on it and thought it was oil but when i looked under the car it was red. It was a few drips on the oil pan and a few on the splash shield. I'm sure its coolant because i was missing some too. This morning on my way to school by serpentine belt started the squeal every time I let go of the clutch. Where this leak is from? My guess is that its leaking onto the belt making it squeal and slip. Its a 03 vr6 24v ...

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.

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?

So lately my 2000 Jetta GLS hasn't been running that smooth I can tell when I'm changing gearing and when I start the car and the car idles around 1000 RPMs. I think it may be the engine miss firing because some times I can feel the car shaking but I have no check engine light. Lucky... Also the coolant is leaking idk what the exact problem is but everywhere I go there is a puddle of coolant under my car.

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).

VW Golf 2000 2.0 GLS engine auto. 158,000 km
Observation 1: The coolant flange broken 3 times, which appear to be caused by pressure inside.
Observation 2: I drove it today to see the problem. During normal driving upper hill, the temperature turned to be higher than normal. 1 or 2 minutes later after red light, I turned off the engine. And then driving for 2 minutes after the green light, the temperature read appeared to go back to normal (a tiny bit higher than normal). Further driving 5-7 minutes, the temperature reading went to the high end again. So I stopped, opened the engine cover and can hear water boiling sound inside the engine. The coolant in the expansion tank was much higher than normal (above the maximum). The coolant is Prestone (not G12).
I would guess that coolant is not flowing inside. But the problem appears to occur randomly. A water pump issue? (replaced at 90,000km) Or could be the thermostat? Why cannot the pressure be released automatically?

This morning, I wanted to drive to work, but all of my coolant was gone. In the last couple of weeks, I had some errors with my speedometer and had it replaced a week ago, which did not fix my problem (the P0722 sometimes still came up).
Could it be that my coolant leaked over the last weeks and somehow messed with my speedometer, or are those most likely independent errors?
My car is a 2000 Jetta VR6 and at this point I don't want to put too much into it any more. If you need more input, let me know.

My mate has bought a mk4 golf and it is loosing coolant. There is no obvious signs of a water leak the car starts fine, goes up to temperature fine, only time the temperature rises is when the car has to work harder. (going up hill) then returns to normal.
Left the car today for a couple of hours and went to check the coolant level and the system was still under pressure when opening the expansion bottle top. There is signs of rusty water around the cars panels where the expansion tank is located. Previous owner said that it used 4 litres of water on a 330 mile round trip. previous owner said it could be the head gasket but there is no cream on oil filler cap.
There is no sign of water leaking from the heater matrix inside the car.

2000 VW GOLF 2.0L, manual, ~190k miles
Driving down the highway my CEL started flashing and the engine power dropped at the same time. I drove two miles to my destination and the idle was very rough and the power was still very low. The codes were P0300, 0301 and 0304.
The coil was replaced about 2 years ago. The plugs have never been replaced. About 2 weeks ago I had a solid CEL with the codes P1255 and P0422... I purchased a new ECT Sensor but did not yet make time to install it.
Could everything be related to the ECT? Or do you think there are multiple issues?

I have a 2000 vw Gti vr6. It leaks coolant smokes and starts to over heat when idling. Does fine when driving down the road. It has a new radiator. When pressure tested I can see a little stream of coolant coming out. But there's no space in the engine bay and I can't see exactly where it's coming from. Like I said it only happens when it's Idling for an extended period of time. It does fine going down the road.

I have an old 83 datsun pickup. It is my first car and I love it and it has more character than most people that I know. one day it just started leaking antifreeze. I looked under the hood and could see a steady leak way down on the bottom driver's side of my engine. What's the problem and how can I fix it? No matter what, getting rid of this car is not an option.
