⚙️ Key Features

• Genuine Volvo Penta expansion-tank bracket
• Factory hole pattern and support geometry
• Maintains tank and vent-pipe alignment
• Designed for marine vibration and corrosion exposure
• Direct replacement for a cracked, bent or corroded original bracket
• Engine type: 12.8L inline six-cylinder turbocharged marine diesel

🔌 Function

Supports the expansion tank and related pipework so coolant connections remain aligned and free from vibration-induced stress.

⚠️ Common Signs of Failure

• Tank movement or rattling
• Fatigue cracks around the mounting holes
• Hose or pipe stress and recurrent coolant leakage
• Corrosion or bracket distortion
• Contact between the tank and adjacent engine components

🛠️ Service Notes

• Offer the bracket up and start every fastener by hand before tightening any of them, so the component is not pulled into a strained position
• Check the mating faces are clean, flat and free of corrosion scale — a bracket that does not sit flat will work loose and let the component move
• Renew self-locking nuts, lock washers, tab washers or thread-locking compound wherever the original assembly used them, and tighten to the figure given in the workshop manual for your engine
• Where the bracket carries a rubber mount or bush, renew that at the same time rather than reusing a perished one
• On brackets in the inlet and exhaust area, never force alignment to make the holes line up — cure the misalignment at its source, or the bracket and the component it holds will both crack
