Golf IV / Jetta IV :: VR6 - Coolant Reservoir Was Slushy Ice
Feb 14, 2016
So it was like -10 here today, and I've had a coolant leak which could be the crack pipe? It's coming from the center of the motor and covering the oil filter housing. Anyway I've been adding distilled water until I could get coolant. So today I went out and the coolant reservoir was slushy ice. So I open the drain and drained a bunch out then added some coolant while it was draining to work along with running the engine a short time with the drain open and that got it flowing out. So I drained just about all fluid and put the half gallon I had leftover of g13 . Tomorrow I will go get more coolant. So the question is did I ruin my motor? Crack the block or heads? Should I fill the rest with 50/50 mix? When I ran the car it held operating temp just fine but the fan wasn't blowing warm.

I have a MK4 2.0L 8v 5 speed and recently I started making trips out to the country that last a bout 25 minutes one way and I usually drive pretty spirited the whole way.
I recently noticed that after each trip my coolant reservoir drops significantly, about 1/2" or 3/4". The oil level never changes and the engine never passes 90C on the gauge.
The outside temperature is about -10C most of the time and I always have it at operating temps before I really get into it.
I can't decide if this is normal because the engine isn't overheating (as far as the gauge says) or a problem because it's using a lot of coolant. I've never been to a track with this or any other car so I'm not sure about the effects from hard driving.
The engine revs to 6.2k RPM and I never go over 5k.

So this weekend my Y-fitting for the coolant hose (coming out of the reservoir) broke, literally after arriving at my friends house about 50 miles from home.
I "mended" it, and decided to try to take it home, as it is my daily. Temperature would get high, but not into the red, and drop back down. On the final rise, it got a bit too close to red for comfort. I drove about 25 miles, and my coolant light was on the majority of the time. The last 3-5 miles, my oil light came on. When I went to pull off the road, I pushed in my clutch and my car died. My first assumption was a head gasket (as I have been there before.
I open the hood and coolant is pouring out of my "mended" y-fitting. I check under the car - no oil, just coolant. The oil didn't seem to be "milky," but there seemed to be some sort of condensation on the filler cap. I checked the dipstick - not milky, just liquidy. I added some oil to the car, and had a friend bring some distilled water, and did a little bit better job of mending my fitting. I poured the distilled water in, and it started boiling almost immediately. I let the car cool for a couple hours and tried to start it, but nothing.
There's no white smoke, but the car just "puts" for a few cranks, and then it goes back to cranking. Looking around the engine housing, there doesn't seem to be any oil; but my car has a lot of grease on the block, so it's hard to say.
I did some searching, and it seems that it could be the oil cooler? I don't have the tools for a compression test, and the car was towed to a gas station, which is about 30 mins from my house.
The car is a 2004 Jetta, 1.8T Manual with the 5-speed.

Why my 2002 Jetta 1.8t does this?
After I drive for a while I have to [slowly] open the overflow cap and relieve pressure in order to not lose coolant while the car sits. It steams for a bit when I open the cap and then the coolant rises in the reservoir then I close it.
If I don't do this then the car loses coolant but I don't see any leaks visible under the car.

Pulled up to a red light yesterday evening and saw some smoke near the right side of the hood. I immediately checked out the temperature gauge and it was fine. Car didn't appear to be overheating. I make it home--2 more blocks--pull into the garage, leave the engine running and pop open the hood.
THE COOLANT IN THE RESERVOIR TANK IS BUBBLING LIKE HOT SOUP AND A NICE PUDDLE HAS ACCUMULATED NEAR MY FRONT RIGHT TIRE--NOT TO MENTION THE TRAIL OF COOLANT LEFT DOWN THE STREET AND UP MY DRIVEWAY.
After some minor research it appears that it can be a few factors (ie, thermostat, fans????) I assumed it was a cracked reservoir (which would explain the leak) but the bubbling it the real issue.

I went to the dealer yesterday for my 105000km service. After it is done, I realized that they overfill the engine coolant reservoir. Should I make an appointment with them again to drain them out and put back the right amount? Or it is completely fine?

I always check the fluids, every 2 weeks or so just to make sure everything is fine, yesterday I found oil inside coolant reservoir.
The last oil change was performed 2 weeks ago and the oil that came out of the engine looked normal to me, no coolant in it.
I want to keep this car because is more than a car for me, I have a lot of plans to do with it but damm it getting annoying.

Yesterday after getting to work i noticed a few drips from under the front of the car, at first i shrugged it off thinking maybe it was condensation or whatever. After coming back to my car about 5 hours later it had made a good sized puddle under the car and i knew something wasn't right. Well on my lunch i got under it and collected the liquid only to find that it was coolant. To make matters worse on the drive home my temp gauge would go to operating temp then drastically drop to almost cold temp.. weird. And last but not least when i parked the car at home i noticed that the cooling fans did not stay on after the car was off, since it was about 95deg this seemed wrong. Took the car to the dealer this morning and I'm hoping its just a loose pipe or something little and not anything that will keep it in the shop for a long time. Car is completely stock except for cat back exhaust, 12,000 miles on the odo.

It has happened to me several times.. The car asks me for coolant but today the reservoir was almost completely empty... I have no leaks and my cooling systems is working fine so where does the coolant go?

Have an issue with the coolant bowl cracking? Just went down to fire up my R this morning and the check coolant light came on. Noticed some coolant around the center seam of the reservoir. Turns out the top nipple was separated from the bowl.

I have a 2013 GTI manual 6 speed with 18K very gently driven miles. Yesterday I noticed coolant on the garage floor and checked the reservoir which was below the fill line.
Went to dealer this morning .....bad water pump. I asked if this was unusual for such a new car with low miles and service writer said yes. After googling water pump failures of GTi's I learned this was not the case.

I have an '01 GTI VR6 and I was driving a couple weeks ago when my coolant light came on. I popped the hood and the reservoir was basically empty. I filled it up with 50/50 g12 and water but it was all gone in about a week. I put water in the car and ran it to see where coolant was leaking from and the only thing I noticed was some brownish colored water dripping off that black ball near the oil pan(I'm guessing it was dripping onto it and not from it). What can I do to find out for sure what's causing the leak and what needs to be replaced? One person told me that my water pump and radiator could be rusted.

So I noticed some grinding noises in my Mk IV VR6 the other day... checked my PS Reservoir and it was empty. Topped it up with some Pentosin, then 3 days later it was dry again. Looked underneath the car and the steering racks were drenched...

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 checked the oil it does not have coolant in it, so that eliminates the headgasket.

My buddy has a 2000 1.8T Passat and he has oil in coolant reservoir. It does not blow out any smoke. It runs fine, and does NOT have coolant in the oil. We pulled off the oil/coolant heat exchanger on the oil filter and it appears to be good. We blocked off one end and filled it with coolant and put compressed air to the other end. Nothing came out. He took it to the shop and they said the turbo seals were good. I can't verify that though.
Head gasket? Worse yet cracked head or block? The car does have 170,000 miles.

Long story short, I got a 2001.5 1.8t M5 Passat with 63k miles 2 weeks ago.
This weekend I was driving around and pulled into the driveway and noticed the coolant was boiling in the coolant reservoir. It also looked like there was some oil in the reservoir. Take it to the shop, turns out that the plastic impeller on the water pump broke at 64k miles. This is wierd because the car never actually overheated. The mechanic doesn't think that the head gasket is blown or i have a cracked/warped head because the car still runs fine. He suggests I replace the water pump, timing belt, coolant reservoir, thermostat and obviously flush the coolant. I go ahead with the repair since its almost time for the TB anyway.
After bending over and taking it from the shop on a timing belt and water pump repair, I think I am all good. Today I open everything up after a few days of driving around just to check up on stuff. I open the coolant reservoir and there is telltale signs of oil in the coolant. Now i think this was an issue before the water pump went. Searching the archives I see that the oil cooler is a common failure. This could have also contributed to the failure of the water pump and maybe the thermostat, I don't know.
So instead of bending over for the mechanic for a second time in a week , I think I'm going to replace the oil cooler and flush the coolant system again and change the oil myself. Poked around looking at the oil cooler and it seems as if there is the slightest sign of an oil leak on the outside, which could mean there is a leak inside. I don't have compressed air so I'm not sure how I can test the oil cooler for leaks.
I am thinking i need:
-Oil cooler (some suggest S4, some suggest TDI one?)
-Oil cooler gasket
-Feed and return lines
-Hose clamps
-g12 coolant
-Oil filter
-Synthetic oil
Should I replace the upper and lower radiator hoses while I've got the coolant out? What else should I replace while the coolant is out. I see people suggest flushing the system several times. Should i use G12 everytime or can I just use water to flush until its clean and fill with G12?

I have a MK4 PD150 with the ARL engine and it's drinking coolant!
I'm no mechanic but I think I've narrowed it down seen as there is no visual leaks on the ground. EGR cooler or head gasket.
I've had the car about a month and the garage I bought it from said that it had been pressure tested so this makes me think that it would more likely be the EGR cooler? It's been sat on my drive for three weeks also as I've just passed my test after recently turning 17.

I have had my certified 2010 Prius since June 2015. Last Saturday I noticed my inverter coolant reservoir was on the low mark. I went to the closest dealer and they topped it off up almost to the full mark for free. I thought it had probably went down from evaporation and I just hadn't noticed it before. Yesterday I went back to the dealer where I purchased it which is about 90 miles away to have the CVT fluid changed. This morning the coolant was back down to almost the low mark. I looked on the ground and can't see any evidence of a leak. Tomorrow I have a appointment to have them check it. Since it is still in the one year certified warranty I don't know how motivated they will be to find the problem when they can't charge me for it. I don't think the level would have went back down right away if there wasn't a leak somewhere. I checked and there have been no recalls done or called for on it.
