Radiator leaks around the top seal
I would take the vehicle to a radiator shop for service, they take apart the radiator and flush and clean every line and put it back together, also, they flush the cooling system and if you want, they replace the thermostat and hoses. I you've never have a cooling system service done to your vehicle. It is time. The cost will be less than just replacing the radiator and your vehicle will run cooler.
When you use a Radiator Sealant, the remains will seat at the bottom of the radiator plugging some lines or clogging the cooling passages and a couple of months later the leak comes back. I don't know any radiator sealant that guarantees a permanent fix and tell you where the rest of the stuff you put in the cooling system went. I don't believe that just dissolves and stays on the system to prevent future leaks.
If the leak is on the metal part of the radiator, if you weld it you'll be ok, but when the leak is where the plastic and metal meet, then the above suggestion will do. If the plastic cover is cracked, just get a new radiator.
Good Luck!! Don't forget to rate this post!! 4 thumbs will be fine!!
