Additionally, the JB Weld may react with the coolant, causing leaks or corrosion. It's generally recommended to replace a cracked radiator instead of attempting to repair it. A damaged radiator can pose risks, including overheating, coolant leaks, and, in severe cases, engine failure.
However, if you temporarily need to stop a small leak as a temporary measure before obtaining a replacement, there are specialized epoxy compounds designed specifically for radiators and can withstand high temperatures and pressures. These epoxy products are available at automotive stores and provide instructions for proper application.
It is important to follow the instructions provided by the manufacturer of the epoxy compound to ensure a secure and effective repair. However, it's still advisable to replace the cracked radiator as soon as possible to prevent any potential risks and ensure the proper functioning of your vehicle's cooling system.
