Parts Desk Insights
Best use case: This is the correct replacement when your temperature gauge is reading erratically, pegged high or low, or when you're getting a coolant temperature warning with no other obvious cause. It's also the right part to replace proactively during a cooling system service on higher-hour engines.
Common issues: Temperature sensors are a frequent cause of false overheat alarms on Volvo Penta engines. Customers often replace thermostats and impellers before identifying the sender as the root cause. If your gauge is fluctuating or your alarm is triggering without a confirmed overheat, this sensor is a cost-effective first step.

Consult your Volvo Penta service manual for hour-based replacement recommendations.
Technical FAQ
