22037527 Tool | Genuine Volvo Penta Part

🔧 Product Description

Threaded adapter used to connect a workshop pressure gauge to the engine lubricating system. It replaces the production pressure sender or plugs into the specified oil passage so actual mechanical oil pressure can be checked independently of the ECU sensor.

• Volvo Penta workshop designation for GM EN-47971
• Adapts a mechanical or digital pressure gauge to the engine oil gallery
• Used for low-oil-pressure diagnosis
• Allows comparison of mechanical pressure with electronic sensor data
• Requires a clean sealing washer or thread seal specified by the manual
• Engine type: Volvo Penta GM-based marine petrol V6 and V8

🔌 Function

Provides a sealed connection between the engine oil gallery and a workshop pressure gauge for cranking, idle and loaded oil-pressure measurements.

⚠️ Common Signs of Failure

• Damaged adapter threads
• Blocked oil passage
• Leaking seal or damaged sealing face
• Distorted hose connection
• Contamination inside the adapter

🛠️ Service Notes

• Special tools are matched to particular engine and drive families — check the tool against the procedure in the workshop manual for your engine before ordering, as an almost-right tool will damage what it touches
• Use the tool only for the operation it was designed for, and do not add bars, extensions or leverage to make it reach further or pull harder than intended
• Inspect before every use and retire anything cracked, bent, spread at the jaws or worn in the threads rather than persevering with it
• Clean, dry and lightly oil the tool after use and store it where the working faces cannot be knocked out of true
