I have noticed some coolant leaking from the underside of the car occasionally. Today I replaced all of the hoses and the thrmostat (180 degree), only to realize it was coming from the coolant overflow tube. What is causing this? Is there supposed to be a tank for it to collect in, like on newer cars? If so, the previous owner tossed it.

I don't care about original stock stuff, but I just removed an old plastic one and purchased a nice polished alum. recovery tank from Summit. I have more space on the pass. side next to the radiator so it is to be mounted in that area. I believe MSA has a new plastic one for sale, which should look clean where ever you decide to mount it. I didn't mount on the driver side because there is already enough stuff on that side, and I'm also watching not to block air flow on that side. As for drilling holes, I am able to use existing holes on the edge or flange of the radiator itself, so if you are not going the orig. or restore route, look around and you can find a place that works for you.

I went by the dealer today, and they said that they do not show a part number until '76 models. I can see where it looks like a place for one where you guys described. I picked up a universal one from Pepgirls today, but have not tried to mount it just yet.

I don't remember my 75 having one until I put one on like Chino's when I started racing it.

If it's pushing out coolant, it could be a bad cap, or it could be that it is running a bit too hot also. Safest thing to do is to verify the coolant temp in the radiator with a cooking thermometer after you get it up to normal operating temp.

The stock gauge and sending unit are notoriously inaccurate.

You could also spend a few bucks for a cheap mechanical temp gauge and put the sending unit in place of the electrical one and drive it a while with the guage placed somewhere inside the car so you can verify the operating temp while you drive.
