I have a 2000 Jetta GLS VR6 with a slow coolant leak. With the exapnsion tank filled to the max line, it takes about a week for the coolant level to reach the bottom of the tank.
I have heard a lot about the crack pipe cracking but if I understand this stuff correctly, the crack pipe is located on the passenger side... in my case, the coolant is definitely hitting the ground on the driver side... although I realize it could be traveling on something and then dripping. Anyway, I haven't done a thorough inspection to try to locate the source, just took a quick look from up top and from underneath but didn't spot anything. Also, I hear a hissing sound for a few minutes after shutting the engine off... it's a steady sound, not like what you would hear when liquid drips onto a hot surface and burns off. This is my first VW so I am unfamiliar with the ins and outs of these things so I don't know if this sound is normal or not.
I appreciate any info you guys have to offer!
