This Kubota tractor radiator is cracked. Radiator repairs must endure high operating temperatures and need to contain hot, pressurized coolant. Adhesives are ineffective in such conditions, as they cannot maintain a strong bond over time when exposed to high temperatures and pressure.

The only reliable method for patching a plastic radiator tank is through a fusion weld. Using Polyvance’s airless plastic welder and nylon welding rod allows for a seamless, durable repair that will last.
