Troubleshooting

Leak persists after application.

Ensure you followed the instructions correctly, including the proper engine running time. If the leak continues, a more serious issue may be present. Consider a professional inspection.

Coolant is discolored after use.

This is normal and a sign that K-Seal Heavy Duty is circulating through the system. However, excessive discoloration warrants inspection. Flush the system if necessary.

Engine overheats after use.

This could indicate a blockage. Check the radiator and hoses for obstructions. If the problem persists, consult a mechanic.

Product is not dispensing properly.

Ensure the bottle is shaken well before use. If the product is old or has been stored improperly, it may have thickened. Replace the product if necessary.
