Mishimoto 1.3 Bar Large Radiator Cap with Coolant Temperature Gauge – MMRC-GL

The Mishimoto MMRC-GL combines a high-pressure radiator cap with an integrated temperature gauge, allowing the driver or technician to monitor engine coolant temperature directly from the radiator cap.

Rated at 1.3 bar (19 psi), it helps maintain cooling-system pressure and increases the coolant’s boiling point for improved cooling performance. Its large-cap design fits most compatible domestic vehicle applications and provides a convenient replacement for the original radiator cap without requiring additional wiring or sensors.

The ergonomic design allows for straightforward installation and removal, while the built-in gauge makes it easier to inspect coolant temperature during maintenance, diagnostics, or performance use.
