cooling system Stop leak
The cooling system stops leaks in radiators, heater cores, welch plugs, and hoses, all without removing or replacing any existing coolant.
Stops leaks in minutes, not hours.
It can be added to existing coolant.
Compatible with all OAT, HOAT, Si and Pi coolants and all inhibitors.
Works in Diesel or petrol engines.
Treats up to 10 litres of water
It is an Idea for sealing small holes and does not discolour existing coolant. One application can fill most radiators' gaps until a permanent repair can be completed.
Add one bottle to the Radiator and replace the cap; the water leak should stop within 30 seconds. If the leak persists, leave the lid off the Radiator until all leaks have stopped, place the radiator cap back on, and check again after a few minutes for any other leaks.
