20881069 Temperature Gauge | Genuine Volvo Penta Part

🔧 Product Description

A genuine Volvo Penta 12-volt engine-coolant temperature gauge for the specified instrument-panel installations. The gauge converts the resistance signal from the matched temperature sender into a stable dial indication so the operator can monitor warm-up, load temperature and developing cooling-system faults.

🚤 Compatibility

Typically suits:

• Volvo Penta TD420VE
• Volvo Penta TAD620VE
• Volvo Penta TAD720VE
• Volvo Penta TAD721VE
• Volvo Penta TAD722VE
• Volvo Penta TAD420VE
• Volvo Penta TAD520VE

• Engine Family: TD, TAD

⚙️ Key Features

• Genuine Volvo Penta 12-Volt Coolant Temperature Gauge - part number 20881069
• 12-volt Volvo Penta panel gauge; not interchangeable with the 24-volt version
• Calibrated for the specified Volvo Penta temperature sender
• OEM panel diameter, terminal arrangement and dial range
• Damped movement provides a readable indication despite electrical and engine vibration
• Supports operator monitoring before an over-temperature shutdown occurs
• Confirm system voltage, sender part number and panel generation before ordering
• Engine type: 12-volt Volvo Penta analogue instrument-panel systems

🔌 Function

Current through the gauge varies with the resistance of the coolant-temperature sender. The calibrated movement converts that electrical change into the displayed temperature, giving the operator a continuous indication independent of warning-lamp activation.

⚠️ Common Signs of Failure

• Gauge remains at cold or full scale
• Reading is intermittent or changes when wiring is moved
• Displayed temperature disagrees with diagnostic measurement
• Gauge responds incorrectly because the sender or system voltage is mismatched
• Corroded terminals create a slow, unstable or inaccurate reading

🛠️ Service Notes

• The gauges under this item type span different face styles and generations — for example the black-faced 0-150°C gauge elsewhere in this range needs its own separately ordered front ring (52-110 mm, black or chrome) — confirm the face style and any ring/bezel arrangement fitted to your panel rather than assuming they match
