Oil In Coolant Overflow Tank?!?!

[dj JINX]

About two months ago i put waterwetter in the coolant overflow tank. I started to notice the water in there getting darker.... last night I emptied alitte on the drive way and it looked like there was oil in the coolant. I checked the rad and it didnt look like oil floating in there.... help:wtf:

are you talking about a rainbow colored film on the top or actual oil in the coolant? When oil and coolant mix, it doesnt turn dark. It turns about the color of a wendys frosty and nice and milkshakey. It almost looks kinda good. Well anyhow, its probably just the coolant, i have seen this before when it hits pavement, it has the rainbow effect like oil does when mixed with water.

Water wetter does that. I don't know why, but I have seen it a bunch of times. It is not oil from your motor, so don't worry. It is the water wetter itself.
