40005807 Freshwater Cooling Kit | Genuine Volvo Penta Part

🔧 Product Description

Genuine Volvo Penta freshwater cooling kit listed for the 4.3GL-J and 5.0GL-J, weighing 20.502 kg and shown for 4 applications. The kit converts a seawater cooled engine to a closed, indirect circuit in which treated coolant runs through the engine and gives up its heat to raw water in a heat exchanger. Freshwater cooling brings domestic hot water and onboard heating within reach, allows all-year running because the coolant carries anti-freeze and anti-corrosion agents, reduces engine wear through higher running temperatures and extends engine life through better corrosion protection. The engine list is the only reliable way to separate it from kit 40005446.

🔌 Function

Converts the engine to a closed freshwater circuit, so treated coolant runs through the engine and raw water only passes through the heat exchanger.

⚠️ Common Signs of Failure

• Overheating after conversion from air trapped in the new circuit
• Coolant weeping at a new hose or housing joint
• Coolant oily or discoloured, pointing to a failed heat exchanger core
• Raw water side furring up, with weak discharge at the outlet

🛠️ Service Notes

• Order strictly by engine designation - 40005446 is the kit for the GXi and Gi engines and 21403117 for the 8.1 litre GiC and GiCE
• At 20.5 kg this is a bulky boxed kit, so allow for freight and check it against the parts list before starting
• Fill with the specified coolant mix and bleed the circuit fully before running under load
• Should the engine need to be fully de-commissioned, the coolant channels can simply be filled with inhibitors

📦 Condition

• Genuine Volvo Penta part
• Brand new
• Supplied in original or equivalent packaging
