Golf IV / Jetta IV :: 2000 - Loosing Coolant - Loss Of Water?
Jan 5, 2016
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.

I have a 2000 passat tdi, over the past months ive noticed that I have been loosing coolant through my coolant reservoir overflow, my car has been running perfectly, my mechanic told me that its likely to be a head gasket problem and he put ceramic sealer in the coolant system, which was a disaster, the coolant pressure became much worse and told he me I needed a new radiator, which he fitted, but there was no improvement, whilst my mechanic was working on the car he noticed that when my car was running if he removed the oil filler cap the engine breathed heavily, my mechanic told me that the engine would need replacing,so I should sell the car as soon as possible.
I found it difficult to believe my trusty VW was in such a bad state, as it has only done 87000s mile and has full service history and starts and runs like a dream. Today I went for a second opinion, they told me that the coolant problem was because of a defected water pump, with most likely the plastic impellers failing, and the engine breathing problem could be down to a blocked breather at the top of the engine.

I have a 2000 honda civic ex that I recently bought used. It ran fine with no problems for a good month then the check engine light came on and it started overheating. I could smell burning oil and see smoke rising from the hood. I checked the coolant and it was all out. So I filled it back up. Drove about 20 miles and during the drive when sitting idle the car would shudder and jolt around for a second, after about 20 miles I could see the coolant that I just filled up was all gone. I could hear some bubbling sound, all of the coolant had burnt away and was steaming. I did some research and it could be a blown head gasket, but I'm not sure and was seeking how to fix it or to clarify if it was a head gasket.

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.

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.

I have a Gen 6 2007 Camry SE V6 that I bought new in 10/2006.
Over the last few months, I've had an intermittent loss of coolant as evidenced by sometimes finding a small puddle of coolant on the floor in the garage.
I also often hear a noise under the hood for a few minutes upon first starting the engine cold. I've been just adding a little Official Toyota Coolant to the coolant reservoir.
I'm unable to see where the coolant is leaking from, but with the water pump problems others are having with this engine, and the noise I sometimes hear when starting the engine cold, I suspect it's the water pump.
I have 70,000+ miles on the car with the extended warranty which runs out in mid 10/2013. These symptoms led to a water pump failure?

I have a Golf 1.8 t 2003 and when the car reaches 4000 rpm on 3rd gear it starts sputtering and can't go above that rpm. it sputters a bit on 2nd gear but at about 5000 rpm but it keeps accelerating. I couldn't try the other gears because i don't have a suitable to reach those speeds (traffic laws speed limits). I have noticed a slight tear on the connection between the hose from the air filter and the T hose. could that be the problem.

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 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.

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.

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.

So as the title says the sunroof in my 2000 Jetta is leaking. I've taken down a, b, and c pillars, and the headliner. Poured water in the drain tray and no noticeable leak.. however when I spray it with the hose, the water overflows over the drain tray at the drain ends and into the car like Niagara falls. I've check all the connections, pinched open the plugs. I've already replaced the sunroof seal, which was noticeably shrunken. The new one fits snug all around but I'm still getting the leak. The water (from what i can tell) over flows the tray, runs down the headliner to the drivers side C pillar and then down into the trunk where the cd changer / safety kit was. I usually park uphill, and the one time I parked down hill and sprayed it with the hose the water was "Niagara falling" into my passenger seat.

I had my SUV (2000 Ford Expedition) tuned up. I'm losing about 1-2 quarts of coolant every couple of days. While I was having the tune up done, I asked the mech to try to find where the coolant is going. He couldn't. He did say that they'd pumped the system up to 18 lbs (it's got a 16 lb cap) and it held for 45 minutes, so I'm a little (little-little) less afraid that it's my head gasket. Questions are these:
1. Could my 16 lb cap be at fault? It got pretty gunky when I mixed the coolants (see my post - Don't cross the streams).
2. Could my rear heat exchanger be leaking and where would the coolant come out? It's got rear air and heat that's controllable form the second seat.
I never see water on the ground or dripping. No white exhaust to detect. Doesn't run rough at all at startup. In other words, none of the traditional head gasket indicators.

I have a 2003 9.5 Saab with a 3.0 liter tdi. It has 160,000 km. The coolant light came on saying that the coolant was low, I took it to the Saab garage. They said that the ducts are compressing and that the water pressure increases in the engine and comes out of the radiator cap. According to them, it will eventually (within days or months) kill the engine. Saab does not make these engines anymore. I took the car also for an oil change which they say is not worth doing.
According to them, these engines have had problems like this (i.e. it is not a one off). We checked and do not see any coolant leaking from the reservoir cap but we see some coolant leaking on the garage floor. We check the oil and see no sign of coolant leaking into the oil and therefore do not think that it is a head gasket problem. We don't fully understand what the garage is telling us, is it a common problem ? How can we treat this ?

I started loosing a bunch of coolant on my tdi which is still under 36k and there is no visible leaks anywhere
Took the car to the dealer last night to get it checked out and they were ready to send me back home telling me there is no issue since they don't see any leaks under the car
Either way after telling them that I have already gone through 2 gallons of coolant they decided to top off the coolant and ask me to drive 200 miles.
I drove 156 miles last night since I need to get this issue resolved and now the coolant tank is empty again... sitting at the dealer while I'm typing this.

Ok 210k truck runs great except I am loosing coolant into #1 cyl. Ive owned the truck since 120k and it has NEVER ran hot not even above normal. I guess due to expansion it will even fill up the cyl nearly hydro locking it, no oil in water/radiator and no water residue in the oil either. I had the intake gaskets replaced thinking it may have been it but it came soon back. I really dont think its an head gasket, has there ever been reported problems with the intakes on these trucks? oh btw 97 2wd with 4.6. Even with coolant getting into the cyl it still runs great just a little white smoke.... I really don't want to replace the engine I think it has a lot of life still in it.

Okay so recently I was driving my 2000 Jetta and the coolant temp light came flashing on, when I went to check the coolant I was surprised to discover that it was like a mud brown color, almost looks like peanut butter. From everything I have read this can be from a few things, either rust build up that is gunking everything up and oil getting into the coolant somehow. I'm pretty sure its rust build up but I was wondering what everyone thinks about this, I was also not using G12 coolant which I'm told now is the premier brand for VW's.

I have a 1996 BMW 328is and recently it overheated on the way to work which is about 20 miles i pulled over let it cool down and now when i drive the car after about 5 minutes it starts overheating and is loosing coolant but i am pretty sure its burning out the exhaust now the person i had bought it from had replaced the head and head gasket no more than 8000 miles ago with thermostat and housing and water pump and radiator so now i get no heat in the car both upper and lower radiator hoses rock solid and burning the antifreeze.
