FAQ

What types of radiator repair products do you offer?
We carry liquid and powder sealants, epoxy kits, and patch adhesives suitable for repairing small leaks, cracks, and pinholes in radiators, heater cores, and hoses.

Are radiator repair products a permanent fix?
They are designed as a reliable temporary or semi-permanent solution for minor leaks or emergency repairs. For major damage, a radiator replacement or professional repair is recommended.

Can I use these repair products with all radiator materials?
Most are safe for aluminum, copper, brass, and plastic radiators. Always check product instructions for material compatibility before application.

How do I use a liquid radiator sealant?
Simply pour the recommended amount into the radiator or coolant reservoir, then run the engine to circulate the sealant. It will find and seal small leaks from the inside as the system reaches operating temperature.

Is epoxy or patch repair better for large cracks or holes?
Epoxy kits work well for cracks and small holes, especially on external surfaces. For larger damage, consult a professional or consider a new radiator.

Will radiator repair products affect coolant or overheating?
When used as directed, they should not affect coolant flow or cause overheating. Improper use or using too much may restrict coolant passages—always follow product instructions.
