How big can a leak get and still be repaired?
Generally, the repair kit can stop a leak and apply a new layer to holes with a diameter of up to 0.75 mm and a groove with a width of up to 0.38 mm. In order to get a good indication of the size of the leak without having to dismantle any parts, you can let the engine idle for 15 minutes. If there is no need to add any coolant within this period and the engine does not overheat then your car is a suitable candidate for being treated with this product.
