After my water pump replacement the coolant level went down a little as expected and then stabilized. Now the coolant light comes on when I hit the brakes or stop on a hill. So that tells me that there's room in the resivor for some water wetter.
If I remember correctly some people said that they found Red Line's water wetter at an Auto Zone. I went to one a few days ago and didn't find any so I asked a person behind the counter and they didn't know what I was talking about. In fact he laughed at me and said , "how can you make water wetter?" I just I explained that it is real, how it works and why it is benificial.
There's a speed shop not far away that I know carries Red Line stuff so I might have to take a trip there.
