The Ghostly Coolant Leak
This is my first post. I've been reading this site for sometime but never joined. Today I actually joined looking for answers. I will enlighten any of you I can on any issues that you are having.
I recently bought an 03 passat with 1.8t. I put it into the shop to get the notorious cts installed along with a thermostat because I had the MIL come on with a coolant problem and this was the culprit. Everything for a month or two was all good until I was on my morning commute of 20 miles and the low coolant warning come on. I got to work and added just a touch of water to the fill line. At first thought, I figured it was due to the burp or cough the coolant system needed to do since they had to replace those components. The shop said it would do that eventually and to just add a little coolant/water.
Later that day I was leaving work and I noticed that there was a puddle of fluid under my car. I examined and noticed that it looked green and felt and tasted just like coolant. We all know that these engines take G12 and that color is pinkish. I thought, this couldn't be coolant and that it may've been my ac leaking although ac was working fine.
I brought car home and parked in drive for 2 weeks without a single drop. I decided to drive it to work one day and it started leaking the same fluid once again. It was again a greenish color. The first leak was dripping from the center of the skid plate under the car. The second time it started leaking it was running from the back of the oil pan and dripping off the front of it.
I decided to take it to the shop and put it on a rack to examine closer. Long story short, the techs put a pressure tester on it to test for leaks in the coolant the next day after the engine has cooled and found no leaks in the coolant system.
Does anyone have any clue what this may be? Is it possible that it could be a coolant leak? If so, is it possible that it would be green and for the reservoir to still show pinkish red and not be brown or gelled?
I am clueless. Any help or suggestions would be awesome. Thanks for your time on reading this and hopefully I can help some of you guys out as well.
Thanks
