⚙️ Key Features

• 7.96 kg
• 139 applications across the V series
• Shares its fitment with hose 3861472
• Cooling System group assembly
• Shell-and-tube closed-cooling assembly
• For small-block gasoline engines

🔌 Function

Passes heat from the closed engine coolant circuit into the raw water flowing through it.

⚠️ Common Signs of Failure

• Coolant temperature climbing, worst under sustained load
• Coolant level dropping with no external leak, or oil film in the header
• Raw water discharge weaker than normal
• Tube stack scaled, silted or blocked on strip-down
• Salt crust or corrosion staining at the end covers

🛠️ Service Notes

• Renew the end cover seals when the exchanger is opened, and check hose 3861472 while the circuit is drained
• Look upstream at the raw water strainer and pump impeller, since debris carried through is what blocks a tube stack
• At 7.96 kg this needs support during removal
