Car Radiator Cap R-124 (Made in japan)

Car Radiator Cap R-124 (Made in Japan)

This R-124 radiator cap seals the radiator neck while acting as a pressure relief valve, keeping your cooling system pressurized correctly so coolant doesn't boil off or leak under heat.

Maintains Correct System Pressure

Holds the cooling system at 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.

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 cause poor cooling and corrosion.

When to Replace It

Inspect periodically for a hardened or damaged seal, a rusted spring, or a faulty recovery valve — common causes of coolant leaks. Always use a 50/50 water and antifreeze mix.
