    Thread: Coolant leak 2000 Jetta VR6

    1. 11-18-2006 04:16 PM #1
      Hello,

      First post here but I have used this forum for info in the past. I'm posting now because I need some information about a coolant leak.

      The sensor this one found here: http://forums.vwvortex.com/zerothread?id=828493

      The sensor works but is leaking. What do you all suggest as a fix; Some thread tape, new sensor, or something else?

      I plan on replacing the O-ring regardless.

      Thanks in advance.
      Shawn

      A new O-ring should fix your issue. Make sure you get a new U-retaining clip as well. If that doesn't work, then you'll need a new housing.

      Make sure that the sensor is what is leaking and not the dummy plug next to it. If you're draining the coolant anyways, you might want to replace it and its o-ring as well.

      I know this is a slightly old thread, but this is the only one that I could find that has my problem. before I even found this thread, I knew what my problem was and I even did what FaelinGL told the OP to do. I have already replaced both of the o rings and it fixed the leak for 3 days. today, I noticed a puddle under the car and I refilled the coolant. I have no reason to believe that the leak is coming from somewhere that is not one of these o rings. what I don't understand is why would this work for 3 days and then start to leak again? any insight?

      You sure it's coming from the sensor and not from the T-stat housing itself?

      well it was leaking pretty consistantly so I replaced both of the o rings and for 3 days I was very happy...not a drop leaked...until today when there was about a cup of coolant in the driveway. I took a look inside the bay and the leak seems to be coming from the same place it was before...the coolant temp sensor. Not to mention the leak started happening when I replaced the temp sensor...I must have put it back together wrong or with a bad o ring, so I replaced them again and it worked...for a couple days.

      It's probably coming from the t-stat housing seal and the coolant is leaking down onto the sensor.

      dammit...I really don't want to have to replace that. I don't have the time nor the heated garage to do it. I'll have to check closer to make sure that's what it is. Thanks for the help Mike and Gary

      The easiest thing to do is look for the highest place that you have dried coolant. That will be the source. **** always flows downstream.
