Small coolant leak? Sealwel has been sorting those for 75 years. 🔧
But it does more than plug leaks. As it circulates, it forms a plastic-like layer over minor leaks, cleans the engine waterways, hoses and radiator, lubricates the water pump bearings, and keeps the whole system in good shape.
Drop it in, drive 5 km, done. Many engine rebuilders add it to every rebuild as insurance against leaks.
We think every workshop around the country should have it handy.
Available as cubes or powder, and works with coolant and antifreeze. Made in Rangiora, New Zealand.
