What causes a pinhole leak in a car radiator?
If the coolant has not been checked or topped up properly, the radiator, hoses and hose connections will become clogged and begin to rust. Over time, such corrosion will cause small holes or ‘pinhole leaks’ to develop in the car radiator.
Where does the coolant go in a car radiator?
A car radiator. The coolant in an engine is passed through tubes inside the radiator, where heat it has absorbed from the engine is dissipated into the atmosphere, before the coolant returns to the engine. Coolant enters the pipes in an overheated state, causing it to become highly pressurised (aided by turbulence inside the radiator pipes).
What causes a radiator cap to open and close?
Coolant enters the pipes in an overheated state, causing it to become highly pressurised (aided by turbulence inside the radiator pipes). This causes the radiator cap to open at a predetermined pressure point. The heat is released, allowing any excess coolant to escape into an overflow tank attached to the side of the radiator.
