1556882 Coolant Pipe | Genuine Volvo Penta Part

🔧 Product Description

This genuine Volvo Penta coolant pipe is an engine cooling-system flow component used in the engine cooling-system pipework. It is manufactured to the original Volvo Penta dimensions and interface requirements so coolant is transferred without leakage, restriction or pipe stress. Maintains the revised OEM service configuration. In service, it carries coolant between the matched D16 cooling-system components. Fitment is controlled by the exact engine or product configuration and serialised parts list; confirm OEM number 1556882 against the installed assembly before ordering.

🔌 Function

The coolant pipe forms part of the closed cooling circuit, routing coolant between the engine and associated cooling components. It maintains a sealed flow path so heat can be carried away from the engine at the correct rate.

⚠️ Common Signs of Failure

• Visible coolant leaks or weeping at the pipe body or joints
• Corrosion, pitting or scaling on the pipe surface
• Cracks or splits causing coolant loss and low expansion tank level
• Engine running hot or overheating due to restricted coolant flow
• Deformed or damaged sealing faces preventing a leak-free connection

🛠️ Service Notes

• Clean both flanges or spigots and check the sealing lands for pitting and corrosion; renew every O-ring, seal or gasket at the joint rather than reusing one that has taken a set
• Lubricate coolant-side O-rings with coolant or a rubber-safe lubricant — petroleum oil and grease swell and soften the rubber and end up in the coolant
• Offer the pipe up and align both ends before pulling any fastener tight, so the joints are not held together by strain from a misaligned pipe or an over-stretched hose
• Check the bore is clear of scale, sealant and debris before fitting, and inspect the pipe for internal corrosion or thinning if the old one was leaking
• Refill with the coolant type and mix specified for your engine, bleed the system through, then check the joints again with the engine hot and up to pressure
