View 6 RepliesGolf 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...

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.
Golf IV / Jetta IV :: 2004 GLI - Slow Coolant Leak
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?

Golf IV / Jetta IV :: 2000 - Coolant Leak When Driving?
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?
View 2 RepliesGolf IV / Jetta IV :: 2004 - Overheating - Coolant Leak?
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?
View 2 RepliesGolf IV / Jetta IV :: Coolant Leak / Dripping From The Bottom Of Car
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.
Golf IV / Jetta IV :: CEL On For Code P2181 Coolant System Performance
Like the title states, I've got P2181 (coolant system performance) CEL on again. I've had this code before and finally had everything serviced. It was off for 5k miles! I've spent a lot of time diagnosing this on the previous occurrences, and was 99% certain it was the thermostat due to the coolant temp dropping a notch or so when engine braking* on the interstate for more than a few seconds.
The current issue is mainly that the car will not heat up quite as fast, but it will not go lower from engine braking for a good chunk of time. I'm getting fairly poor MPG compared to what I was getting a month or two ago. The major changes are winter fuel blends and winter tires, which I'm sure affect the MPG a little, but I would hope not as much as I am seeing. Old average was around 27mpg combined and 30 or so for mostly highway, now I'm getting 24 tops. This is likely due to engine temps not being up to allow for most efficient fuel burning.
First plan is to change the CTS and see if that will fix it. If the code comes back after that, I'll have to check the thermostat and coolant mixture, but I wouldn't expect it to last only 5k miles.
Current: 105k
Thermostat and coolant changed at 100k
Water pump at 80k
CTS sometime around 70k
Engine braking lowering temp due to no fuel being ignited and coolant still circulating through the system if thermostat open.
Golf IV / Jetta IV :: Code P2181 Come Up Twice - Small Coolant Leak And Some Oil Mix?
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).
Golf IV / Jetta IV :: Coolant Leak - Dripping At Front Right Tire
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.
Golf IV / Jetta IV :: Coolant Leak Coming From Area To The Right Of Oil Filter
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?
View 11 RepliesGolf IV / Jetta IV :: Coolant Leak On Passenger Side - Water Pump?
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.

On my 1.8t jetta she is leaking coolant slowly. Just started when it got cold out. It is dripping down the oil pan right down the center. It is falling off the oil drain plug. Was reading that it could be the water pump leaking but then it wouldn't be in the center of the pan. Got it jacked up now so here are some pics.

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.
