You Will Need
- Radiator hose
- Duct tape
- Mustard powder
- Stop-leak coolant
- Welding equipment and expertise
- New radiator
Add stop-leak coolant
Add a stop-leak coolant to the radiator for a more long-term fix. Be sure to follow the manufacturer's directions.
Add mustard or pepper
Try adding 2 tablespoons of mustard powder or ground black pepper to your engine coolant if you have a small radiator leak. The mustard or pepper will migrate to the leak and form a temporary seal.
Consider welding cracks or multiple radiator leaks if you have the expertise and equipment. Otherwise, you will probably be better off replacing the radiator. Enjoy a stress-free ride.
Check radiator hose
Pull the car over to the side of the road if you are driving it, and check for a broken radiator hose. In an emergency, you may be able to repair it with duct tape.
