ADDITIONAL BENEFITS:
The heavy-duty cooling system stops leaks and makes an excellent companion for campers and 4-wheel drive enthusiasts, as it can be carried in a glove box or a toolbox. If an accident happens, you can fix a leak up to 2 millimetres in diameter in seconds. Alternatively, it can be added to a radiator before a trip, so it will be sealed instantly if something goes wrong.
APPLICATION:
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 a permanent seal is established.
