Coolant leaked into interior, what next?
Hello all. First post, but I have been lurking a while. Just bought a really nice '77. Has had a few small issues here and there pop up as I have been giving it the rounds. Yesterday I went to vacuum it out and that's when I found the puddle in the passenger foot well. not good. This car has been fairly rust free, but I had to pull the carpet to inspect, and it doesn't look great. Probably mostly surface rust, but I imagine there has been a leak for some time before I purchased it. I think it was a slow leak but the carpet is fairly saturated.
My question is, what is the correct course of action? I plan to remove the carpet and wash it down. I have very little knowledge of chemistry, but I assume that antifreeze is obviously water soluble, so a good hosing down and drying should remove the antifreeze.
I think I need to remove the sound deadening and get to the bare metal, sand down the bad areas, and probably coat in Por-15 and top coat. Then put some sort of sound deadening back in.
until last month, I never sat in a Datsun, let alone worked on one, but I noticed that when I sopped up the puddle of antifreeze, more would move forward from a seam where the front passenger seat rail goes across. I have not removed the carpet yet, so I don't exactly know the lay of the land, but It seems that coolant has found its way inside of all the little nooks and crannies. I am worried that I won't be able to get to some of the area that it has leaked into.
I know that antifreeze is treated with all sorts of rust inhibitors, but I don't think it acts the same out in the open, I have heard that it is high in acidity. can anybody chime in and help me with what I should do to prevent rust in the future? I would really appreciate it. Antifreeze leaves a residue after it dries, and I don't know how that will react with the metal over time. As any Z owner knows, I just want to keep this thing alive as long as I can.
Also, I am going to throw this out there. I am looking for an upper steering column cover in good condition.......
Thanks for any help with the leak issue. I have since bypassed the core so this doesn't happen again. (one day I will take care of the valve or core, but not now) This is a good weather toy, no DD.
I've got pictures, but not sure how to post.
