21087695 Coolant Pipe | Genuine Volvo Penta Part

🔧 Product Description

A genuine Volvo Penta formed rigid coolant pipe used across the early and first revised TAD732GE/TAD733GE packaged cooling systems. The pipe connects the circulation-pump/radiator circuit using serial-specific hoses and clamps. Its formed route provides the necessary clearance from the fan, shroud, charge-air piping and cooling-package frame.

🚤 Compatibility

Typically suits:

• Volvo Penta TAD732GE EDC4
• Volvo Penta TAD733GE EDC4

• Engine Family: TAD

⚙️ Key Features

• Rigid coolant-transfer pipe for TAD732GE/TAD733GE packaged cooling systems
• Used in both SN10410387-10590631 and SN10590632-10944313 diagrams
• Formed route prevents fan, belt and support-frame interference
• Correct end diameter suits the specified hose clamps
• Provides a stable connection point while adjoining hoses absorb vibration
• Engine type: D7-series generator diesel packaged cooling system

🔌 Function

Carries coolant between the circulation-pump, radiator or associated cooling branches while providing a rigid, correctly routed section within the cooling package.

⚠️ Common Signs of Failure

• Coolant leakage from corrosion pinholes or damaged ends
• Chafing where the pipe contacts a bracket
• Distorted end preventing the hose from sealing
• Restricted flow from internal corrosion or deposits
• Recurring hose failure caused by a bent or misaligned pipe

🛠️ 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
