Radiator Stop Leak
Radiator stop leak is an additive poured into the cooling system that seals small leaks with particles or fibres.
What is Radiator Stop Leak?
It may stop seepage from tiny holes in a radiator. It cannot fix split hoses or failed water pumps. It is meant as a temporary measure. If you use it, tell the workshop, because it changes how the cooling system must be flushed.
How it works
Particles circulate with the coolant and lodge in small openings where coolant escapes.
Why it matters for your car
It can also clog heater cores, thermostats and fine radiator passages. Many workshops recommend proper repair instead.
