Car Radiator Cap R-123 (Made in Japan)
A radiator cap does more than seal the radiator neck — it acts as a pressure relief valve, keeping your cooling system running at the right pressure so coolant doesn't boil off or leak out under heat.
Maintains Correct System Pressure
Keeps the cooling system pressurized to around 16 PSI, raising the coolant's boiling point so it stays liquid even as engine temperatures climb.
Manages Coolant Expansion
As coolant heats and expands, the cap releases the excess into the reservoir tank, then draws it back as the system cools — keeping the radiator properly filled without overflow.
Prevents Air Pockets in the Cooling System
By pulling coolant back from the reservoir instead of letting air in, the cap helps prevent air pockets that can cause poor cooling and corrosion.
When to Replace It
Inspect the cap periodically for a hardened or damaged seal, a rusted spring, or a faulty recovery valve — common causes of coolant leaks and pressure loss. Always use a 50/50 water and antifreeze mix.
