1618597 Temperature Sensor | Genuine Volvo Penta Part

🔧 Product Description

This is a genuine Volvo Penta temperature sensor from the Instruments system group, supplied under part number 1618597. It monitors coolant or fluid temperature and feeds that signal to the engine's gauge or instrument panel so the operator can track running temperature. It is catalogued for the DH10A diesel engine.

🚤 Compatibility

Typically suits:

• Volvo Penta DH10A

• Engine Family: DH
• HP Range: Approximately 360 HP

⚙️ Key Features

• Dedicated gearbox-temperature sensing application
• Designed for DH10A electrical systems
• Works with the associated gearbox sender circuit
• Direct replacement for OEM part 1618597
• Includes provision for the related sealing O-ring

🔌 Function

The sensor converts fluid temperature into an electrical signal that is read by the instrument gauge or engine monitoring system. This gives the operator continuous visibility of operating temperature so overheating can be identified before damage occurs.

⚠️ Common Signs of Failure

• Gauge reads erratically, jumps, or pegs high and low without a real temperature change
• Gauge stays at zero or shows no reading at all
• Temperature warning alarm triggers when the engine is running normally
• Corrosion, coolant weeping, or damaged threads at the sensor body
• Intermittent readings that change when the connector or wiring harness is moved

🛠️ Service Notes

• Check the replacement is the sensor specified for your engine and instrumentation — sensors sharing a thread can have quite different characteristics, and a mismatch gives plausible but wrong readings
• Let the engine cool and depressurise the system before removing a sensor from a coolant or oil passage, and be ready for the fluid that will come out
• Clean the threads and sealing face in the housing, fit a new sealing washer or O-ring where one is used, and do not pack the threads with sealant on a sensor that earths through its body
• Tighten to the figure in the workshop manual with a spanner on the hexagon only — these bodies crack easily and the thread in an alloy housing is easily stripped
• Reconnect the plug or terminal clean and secure, route the lead clear of hot and moving parts, then top up, bleed and run the engine and check the reading is sensible and steady while watching the joint for weeps
