Keep your Malibu Monsoon running at the correct operating temperature with an OEM-style M-Series coolant temperature sensor designed for reliable readings and smooth engine management. A failing coolant temp sensor can cause hard starts, incorrect gauge readings, poor fuel economy, or engine alarms—this replacement helps restore accurate temperature data to your boat’s ECM and dash display.
