Need a New Radiator Cap?
Maintain your BMW E30 cooling system with the right expansion tank cap. The 1.4 bar cap works well for most setups, while the 2.0 bar cap is ideal for higher-stress or modified engines, helping the system handle increased pressure. Replace old, brittle, or faded caps to keep your cooling system performing reliably.
