Leak stopper for radiator - If you have a radiator that is leaking, there are a few things you can try to stop the leak.

Radiator sealant: You can use a radiator sealant product that is specifically designed to stop leaks in radiators. These products are available at most automotive stores and are easy to use. Simply pour the sealant into the radiator and let it circulate through the cooling system. The sealant will fill any cracks or holes in the radiator, stopping the leak.
Epoxy putty: Another option is to use an epoxy putty. This is a two-part adhesive that can be molded and shaped to fit the specific area of the radiator that is leaking. Once applied, the putty will harden and form a seal, stopping the leak.
Radiator tape: There are also special tapes available that are designed to seal leaks in radiators. These tapes are made from a self-fusing silicone material and can be applied directly to the leaking area of the radiator. The tape will create a tight seal, stopping the leak.
It's important to note that while these solutions may stop the leak temporarily, it's still important to have the radiator properly repaired or replaced as soon as possible to prevent further damage and potential overheating of the engine.

How to use radiator stop leak - Radiator stop leak is a product designed to seal small leaks in the cooling system of your vehicle.
Here are the general steps for using radiator stop leak:
- Allow your engine to cool down completely before starting the process.
- Open the radiator cap or coolant reservoir cap (if your vehicle has one) to relieve pressure from the cooling system.
- Shake the bottle of radiator stop leak thoroughly before use.
- Pour the entire contents of the bottle into the radiator or coolant reservoir.
- Start the engine and let it idle for 15-20 minutes with the heater on high. This will circulate the product throughout the cooling system and help it to seal any leaks.
- Turn off the engine and allow it to cool down again.
- Check the level of coolant in the radiator or reservoir and add more if necessary.
- Replace the radiator or coolant reservoir cap.
Drive your vehicle normally and monitor the coolant level and temperature gauge. If the problem persists, it may be necessary to have a professional mechanic inspect the cooling system for larger leaks.
It is important to follow the instructions on the specific product you are using, as different brands may have slightly different application methods. Additionally, radiator stop leak is designed as a temporary solution, and it is recommended to have any leaks professionally repaired as soon as possible.
