I've never had a leak before in my anniversary and now all of a sudden I have a coolant leak. Once I start the car and run it for a short time and shut it off I lose a few ounces of coolant. I inspected under the hood and the coolant seems to be leaking onto my tranny. I am unsure where exactly it is coming from.
View 17 RepliesI think its a flange that connects to hoses, they want to charge me 140 to repair. would this be something i can do myself?
View 5 Replies2003 Jetta Gli seems to have a very small coolant leak. The leak is small enough that I don't even notice a puddle on the ground the light on the dash told me it was low. It is the Vr6 motor. Also I don't know if this is the right forum for my car the title says 2004.5 Gli mine's an 03. If this is a big deal just let me know and I'll delete this post and go else where.
View 4 RepliesI've had the car about 3 months now. It runs fine, never overheats, but I keep having to add coolant (every 2 weeks or so), but I can't see a leak anywhere.
I searched and found one guy that said it could be a bad expansion tank cap, and another that said it could be a tiny leak that only leaks when driving.
Anyway, when replacing my axle, I noticed this:
If that's dried coolant, where would that be from?
Well I first had a slow leak, which was happening because I had a bad O-ring for my coolant temperature sensor. I replaced the O-ring, and I also replaced the whole coolant flange for good measure. After that I added some coolant, and started her up. And before i knew it, there was a pool of coolant under my car. It seems like the hose coming downward from the flange is swelling up (look at the pictures). But I have no clue what this hose is, or what it does.

View 2 RepliesSo I noticed one day when I was standing outside of my car right after I had turned it off that I could hear the coolant bubbling some. I had just recently flushed the coolant, put on a new water pump, thermostat, and put in a new reservoir with a new cap so I figured it was just some air in the system because there was air in the top radiator hose. So I just worked the air out and thought that was it. The next time I drove my car it did it again and there was no pressure release when I took off the cap either. I ended up getting the head worked on (valve job and check the head for warping). Even after all of this my reservoir doesn't seem to build pressure and every time there also seems to be air in the top radiator hose. After the car is warm I can work coolant back in the hose and 5 minutes later theres air back in it. I've pretty much replaced everything with the cooling system besides the hoses within the last year so I don't know what it could possibly be.
View 2 RepliesHad it done at 87K years ago. Coolant light came on car had been rattling. Parked and coolant came leaking out. At 157K now was gonna replace belt at 167k, that's 80k since the last job. My guy says had I drove it further would be looking at a new 1.8t.
Does this sound about right to you since it's been 70k since that last timing water pump job. Why didn't the car overheat? Chipped at 40k with apr and very conservative driver. I suppose it just depends on too many variables why the job needs to be done 10k before I originally planned to do it.
I have a 20th 1.8t. It was running fine last week but all of the sudden i was only getting about 4-5 psi. I have check all over vwvortex for somewhat of an answer. I have no C.E.L.. I have checked for vacuum leaks with nothing coming up. I tried to check for boost leaks but it comes out of the dipstick hole. I have undone and re-installed the pancake pipe. The DV is holding pressure.
View 1 RepliesI just got a 337 a couple weeks ago and I noticed today that there is oil underneath the body of the car and around the turbo housing. The car runs fine, idles fine and seems to boost just fine and every time I check the oil level with the dipstick it reads the same every time and it doesn't leave oil behind whenever I park. I'm extremely confused and a bit worried.
View 12 RepliesI replaced my timing belt, tensioner and water pump last weekend because I noticed I was leaking coolant from the water pump. The other day I popped my hood after driving and notice the reservoir bubbling a little bit because it sounded like the coolant was boiling and the line coming into the top of the reservoir felt hotter than normal. I opened the cap slowly and never heard any pressure release. I figured it was air in the line somewhere so I tried to work the air out. It sounded like the air came out and I took it for a drive and I finally heard pressure release after 3 different attempts. I opened the cap later when it was cool and noticed that the coolant was still at the original level.
Then the next day I was driving and came to a stop and noticed white smoke coming out when I gave it gas. It still drove fine though. I pulled over and opened the cap slowly but didn't hear any pressure release. I put in a little bit of radiator sealant and it seemed to do the trick.
The car has never overheated and there's no oil in the coolant or coolant in the oil. The heat also seems to be working correctly and my fans come.
This is my second vw I've owned and now I own a 20th ae gti. Just the other day I got out of my car and smelled antifreeze. So I popped the hood and realized there was no coolant in the reservoir.. So I went to my dealership, put some in... well that obviously isn't my problem, because the next day it was gone. Again. This is on sunday so I can't do anything about it. I made an appt to drop it off tonight @ my volkswagen dealer. It's not leaking, not smoking or burning, and the temp gauge isn't moving at all.
View 20 RepliesRecently its been pretty cold here, and in the morning or when it sits for awhile i start her up and about 10secs after i start her the little "stop" light comes on and says "check coolant". so went through all that, checked the service manual and dont see any red flags. and if i were to turn it off and then turn it back on it wont show again... but still curious.
View 6 RepliesWhat these codes mean and what I need to do to fix this?
Codes:
P0141 o2 sensor heater circuit bank 1 sensor 2
P0138 o2 sensor circuit high voltage bank 1 sensor 2
P0036 H02S heater control circuit bank 1 sensor 2
So the dealership told me that my Camshaft seal was leaking a bit, which is the shaft moon one right? Well if it was leaking wouldn't I notice oil spots on the ground? I have yet to see any spots on the ground. Is there another way to check?
View 1 RepliesWould an exhaust leak throw CEL?
View 6 RepliesSome questions I have regarding he bad gas mileage my car is getting. Up until winter, my car (2005 mk4 gli) was getting 300-330 miles to the tank. I thought was reasonable, about 150 to a half tank. The setup is pretty normal, apr stage 1 tune (87,89,93,100 octane) with bolt ons (upgraded n75, DV, things like that), a cat back exhaust (unsure of brand), 90k miles was just passed last week. Timing will be done in the spring.
The car has no stutters upon acceleration and idle is staying pretty consistent about 900 rpms. I know there is an exhaust leak, at the flex pipe as I seafoamed the car this fall and discovered that. My question is, which down pipe to you suggest to be the best for the money? I've seen a bunch of different brands, weather it be 42dd, ecs, places of the such.
Would it be cheaper and more efficient to just get a turbo back or stick with the cat back and stay happy? Also, I'm assuming if the leak is in the flex pipe, that the down pipe needs replaced all together. The car DID have a check engine light, for the leak. Since winter the cel has gone away and the gas mileage dropped drastically. When I get a new down pipe or fix the exhaust leak, I also want to change the rear O2 sensor. I believe personally this maybe causing my gas mileage info.
Lastly I have a fuel filter to replace the oem one that's been in there. The same thing happened to me last winter and when summer came around, the gas mileage went up to normal 300-330. I drove to h2oi and was getting well over 30 mpg. Now I'm lucky to get 18mpg.
i have a 04 gli torando red i spike at 12psi and hold at 10psi. the last three days im only getting 5 psi i fixed some vacuum leaks and it went back to 10psi then today back to 5psi dont know if its chipped it does have fmic and air intake and bov...
View 8 RepliesI'm having some issues with my brake fluid going low every 2-3 weeks. I get the 3 beeps on the brake light and the flashing. Sometimes it's constant and flashes 15+ times. Sometimes it comes and goes throughout the day or even the week. After I fill up my fluid, it's fine. Usually, have to fill up a pretty good amount though. Almost a whole small bottle sometimes.
Obviously I'm having a leak but I'm not sure where. I'm a noob when it comes to brakes. My brakes work fine, clutch feels fine, etc.. I read around and was told it could be the clutch slave cylinder leaking, but is this common on the O2M? I looked at the lines around the master cylinder and nothing seems to be leaking. Also, I'm not noticing any brake fluid on my shoes or in the cabin. Any tips on what to check, what's common? Are the leaks most likely going to be in the engine bay?
Stop check coolant light came on dash tonight. Scanned the car no code. Did a search pointed towards coolant temp sensor. Car had it replaced by vw estimate of 30,000 miles ago. I tried to see if its green top sensor appears the very bottom ring is green but top is black maybe vw's is different than ecs? Planning to do water pump, belt kit from ecs anything else i should be looking at?
View 1 RepliesLast night I went to drive my car and my coolant light went on. I checked the overflow and it was very low. There was barely any left in the overflow. I thought this was strange because I had just checked the coolant a couple days ago. The coolant that was in my car was an orange color (after searching I realized that I think this is g12 which I was unfamiliar with). Before searching I added Prestone 50/50 pre diluted green coolant. The bottle said it was mixable with any type of coolant color or kind. After reading more threads I'm seeing that I think the g12 just contracted with the cold weather and I should of just left everything. I have barely driven the car since adding the prestone. Am I doing harm mixing in the prestone? If so, How can I fix this?
On another note, With the cold weather my temp gauge seems to be acting a little funny. Once the car is up to operating temperature the gauge will then drop around 40-50 degrees. It will then stay like this while im driving, but then will go back to normal once the car is stopped and running.
