22037536 Tool | Genuine Volvo Penta Part

🔧 Product Description

Workshop test tool used to pressurise a removed cylinder head or its cooling passages so cracks, porosity and valve- or seat-related leakage can be identified before the head is returned to service.

⚙️ Key Features

• Cylinder-head leak-testing application
• Allows controlled pressure to be applied to the test circuit
• Used with blanking plates, plugs and regulated air or test fluid
• Helps identify cracks and porosity not visible during inspection
• Cylinder head must be cleaned and securely supported
• Engine type: Volvo Penta GM-based marine petrol V6 and V8 cylinder heads

🔌 Function

Seals and pressurises the cylinder-head test circuit so external leakage, internal cracks or pressure loss can be observed.

⚠️ Common Signs of Failure

• Pressure loss within the tool or hose
• Damaged sealing faces
• Cracked fixture or distorted plate
• Faulty regulator or gauge
• Missing plugs or adapters

🛠️ 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
