Golf IV / Jetta IV :: 2003 - Coolant Leaking During Hot Days
Jun 18, 2014
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.

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 ...

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.

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.

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?

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?

We have a significant coolant leak. The attached pic is of a coolant pipe which runs down from the rear of the head at the firewall. This was taken from the underside looking up.

Car: 2003 Jetta VR6 GLX 24V
Sometimes when I start up my car ( I want to say when cold, but I haven't tried after its warm yet), the coolant light and warning come up. I obviously checked the coolant, and it is a little low. But it's been where it is since I bought the car, and I haven't noticed any leaks. After I turn the car off then on again the light goes away.
The car is running perfectly fine, it's not running hot or cold. Another thing I have noticed is that my fans don't seem to be working. ( I know it's a common problem). But I'm thinking this could be the fact that it's below 0 today.
I haven't gotten it scanned yet, but what's going on; i.e., Thermostat, sensors, fans etc..

When it gets hot outside and the car warms up (15 mins or so of highway driving), the stick gets extremely hard to move and it doesn't go back to center when it's out of gear. So I could push it all the way left or right without putting it in a gear, and it would stay there, it wouldn't pop back to the center like it should. It becomes really annoying and difficult to drive because it gets so stiff and hard to move, what could be causing the problem? I've already adjusted the shift linkage and that didn't work.

My issues: when I'm on gear 1 for example, on hot days, and only on hot days ( 25 deg.c and more) when I put it on neutral it suppose to go at "home" position ( i think this is how you guys call it, like align with the 3rd gear) But it stays align the the first.
Same with all the gears. It's stays aligned with the gear I just left.

i have a 03 gti vr6. 24v 6 speed. it started losing coolant the other day. but the thing is the radiator all the hoses and the water pump(s) are all dry. its fine when its cold, holds coolant just fine. but when it warms up its only fine at idle, so im guessing its some sort of pressure related leak. the car goes through half a gallon every mile or so. only the inner fender on the left side is soaked and the suspension components on that side as well.

I recently got the solid check engine light for my 2003 VW Jetta 1.8T GLS. I used a bluetooth OBDII dongle and Torque Pro to pull the code P0118. This seems to coincide with my symptoms:
Car idle at start in park stays around 1100RPM then in reverse it drops to 1000RPM then back into park and it stays around 900RPM and keeps that at idle.
If I start the car then immediately reverse out of my driveway then the car has a very rough idle but if I wait around 5 seconds in park idle then reverse out of my driveway it is smooth.
My car dash thermometer stays pretty close to the bottom low then after about 4-5 minutes it shoots up to 190F and stays. Gas mileage is also very poor.
I looked up a tutorial which shows the parts needed and how to replace the sensor : [URL] .....
I removed the engine cover and believe I found the coolant temp sensor in the spot the tutorial shows. My question is if there is anything I should be aware of before attempting to replace this sensor that this tutorial doesn't cover? I took a screenshot of what I believe is the coolant temp sensor.

My 2003 GTI 24V VR6 is leaking coolant pretty quickly from the passenger side of the engine compartment. I have a new water pump in hand. If I'm replacing the water pump, would it be smart to go ahead and order a thermostat and metal crack-pipe to replace at the same time that I'm having the water pump installed? I'd hate to get the water pump installed, and find out that the leak is at the crack pipe.

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.

Ok, I own a 1990 Volkswagen Jetta GLI that I bought from my neighbor about 4 months ago, and recently, it started having problems. It's idling very high, around 1,500-2,000 rpms, it's leaking coolant, not from the bottom of the reservoir but from the top, and it's slightly overheating. Oh yeah, the speedometer stopped working. I've recently taken it to the shop twice, the first time to get the reservoir replaced, and the second time to get radiator replaced.
I have had problems with it stalling in the middle of the highway during traffic because it over heated. I commute daily to and from college and I want to make this car last as long as possible as I do not have the means to buy a new car. I have noticed that there seems to be a build up of air in the reservoir. I witnessed it leak, and there was a hissing sound coming from it. Also with the speedometer, the light doesnt turn on for it and that there is a clicking noise coming from it. Any tips?

I was driving home from work on Tuesday and I saw a message flash across the MFD saying that I needed to check coolant and consult owner's manual. Also the coolant light was constantly flashing. I was quarter mile from my house so I just drove home, checking the temp to make sure it was ok. I got home and opened the hood to see no coolant in the reservoir, but there was some in the hose. I was like "ok cool I just bought this car 3 months ago but not a big deal." I also looked on the ground under my car quickly and there wasn't a leak. I happen to live about 500' from a VW dealership so called them up and they said bring it over.
When I got there the SA came out and took a look and said to give him 5 to fill it up and I'd be on my way. As I'm waiting in the lounge, I notice a puddle on the ground under my car. I told him about it and he confirmed coolant leak. But because I didn't buy the car from them, they wouldn't give me a loaner, so I had them fill it up and I took a ride to where I bought the car (30 mins away). Now I'm driving a new Jetta. I got the call from Balise yesterday (the dealership I bought it from) and they said my radiator core was defective internally, they overnighted a part and they started fixing it yesterday morning. Since it's such an involved job, only a master tech can do it and there might not be one there today (which I have to check on around noon) so I might not get it back until Tuesday. But I really can't complain (other than the fact that it's a brand new car), I have a car to drive and it's being fixed properly.
It probably was that damn lowerthanzimmy sticker. I realize defective parts are made, they can't catch all of them before they're installed.

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 2003 Toyota Camry with 210,000km on it. Today I popped the hood, noticed the coolant was slightly low in the over flow reservoir so I looked around the engine bay. Now I know generally coolant does not go up that far and it's just oil... But this has got my head turning. There's a crusty coolant residue drip that looks to start at the valve cover. At first I thought maybe the water pump was leaking, and the pulley was spinning it farther up, or spraying back from a rad leak when driving. but the fact it's crusty and A clear line that looks like a drip that's a slow leak and has crusted over time makes me wonder.
I mean generally coolant wouldn't come out of the valve cover unless it was right full of coolant, causing enough pressure to push it out... Am I wrong ? Once I get to the shop on Monday I'm going to pressurize the cooling system and pull the spark plugs and the valve cover to look at the head, The highest spot I see the drip start is the valve cover, only thing I could think of is the intake leaking, and traveling over there but even then, it doesn't make sense to me. The thermostat housing is about 2.5" under so it can't be that... It's such a small leak, the reservoir is only down about maybe half an inch and the oil looks clean as can be.... There's some pictures below that you can somewhat see it.

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.
