⚙️ Key Features

• Genuine Volvo Penta oil-cooler mounting bracket
• Used in D3 transmission connecting-component installations
• Supports the cooler and reduces load on oil hoses
• Factory mounting-hole spacing and component clearance
• Direct replacement for a bent, cracked or corroded original bracket
• Engine type: 2.4L inline five-cylinder common-rail marine diesel with mechanical marine transmission

🔌 Function

Supports the transmission oil cooler in the correct position, preserving hose routing and preventing vibration loads from being transferred into the cooler connections.

⚠️ Common Signs of Failure

• Oil cooler movement or vibration
• Rattling from cracked metal or loose fasteners
• Oil-hose chafing or misalignment
• Fatigue cracking around the mounting holes
• Cooler or hose damage after bracket corrosion or distortion

🛠️ 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
