Nissan 214307999C — Radiator Cap
Overview
Radiator cap Nissan 214307999C maintains cooling system pressure at a rated 0.9 bar. The dual-action spring valve regulates coolant boiling point and diverts excess fluid to the expansion tank during thermal expansion. Construction features a stamped steel body finished with zinc plating to resist corrosion. The internal pressure release mechanism incorporates high-grade EPDM rubber seals rated for temperatures up to +125 °C and compatible with standard ethylene glycol mixtures. Key dimensions include a 45 mm outer cap diameter and a 28 mm lower seal diameter. OEM part number 214307999C matches factory production specifications. Proper function of the return vacuum valve prevents cooling hose collapse as the engine cools down.
This component fits Nissan Almera N16, Note E11, Tiida C11, Qashqai J10, X-Trail T31, Micra K12, and Juke F15 models fitted with 1.2, 1.4, 1.6, 1.8, and 2.0-litre engines built between 2000 and 2016. Replacement is required when the main tension spring loses elasticity, rubber seals show cracking or hardening, or scale buildup jams the release valve. Mechanics should replace this cap upon noticing coolant residue around the filler neck, swollen radiator hoses under system load, unexplained coolant loss without visible external leaks, or recurring engine overheating symptoms.
