How to fix my leaking radiator in my 2000 ford taures without replacement?

I have a bad leak right under where my hose connects to my radiator on the battery side of the car. I have to constantly put water in it just to get to and from work. How can I fix it without replacement I can't afford a replacement radiator. And my car is also making a weird slap knock noise right down below the radio and air controls.it only makes the noise every once in a while but its loud and last about ten to twenty mins? What can I do without taking it to a shop I can't afford right now?

Are you sure it isn't just the hose that went bad?

You can buy a metallised epoxy putty to repair radiators. It's a two pack item and can be applied to damp surfaces. If you can clean up and dry the leaking area it will work better of course. All major supermarkets or DIY stores will sell it. Plastic Padding is one brand.

You can fix the radiator with epoxy putty (eBay is probably cheaper than your local hardware shop). Drain down the coolant (it sounds as though it can do that on its own!) and take out the radiator. Let the area around the split dry thoroughly and remove any rust or flaking paint. Now knead the putty according to the instructions on the pack and force it into the split, leaving a smooth lump on the outside. If you can get at the back of the split through the hose connector, smooth that down as well. Now leave it at least 12 hours before connecting it all back together.
I don't know about the slapping noise. Is there something loose catching the fan?

Call a radiator shop in your area and see if the do free pressure testing on radiators, if they do and get it checked out it may not be the radiator but the hose. If the hose is bad replace/tighten or repair the radiator as suggested and start putting money aside for a new radiator. Check out radiators.com they have pretty good prices

If the top plastic part of the radiator is leaking there's nothing that's going to seal it. Sounds like you've been running straight water in your cooling system. That's going to ruin the water pump seal and rust up the inside of your motor. All that rust will plug up the heater core and radiator. Saving the $120 a new radiator would cost is now going to turn into a very expensive repair bill. I wouldn't be surprised if you're overheating the motor and you sure as hell are going to learn the hard way!

You have a 2000 Taurus. If you want to drive it then prepare to have money to fix it or the problems will compound and the car will implode. Everyone wants to but you can't drive old cars for free. Use the money that you don't pay for car payments and fix it right.
