Manufacturer

VOLVO

Features & Benefits

• Accommodates excess coolant volume during thermal expansion to prevent system over-pressurization
• Integrated level sensor port helps maintain proper fluid monitoring within the cooling system
• High-strength polymer construction resists the cracking and contamination common in high-heat environments
• Direct-fit design supports reliable engine temperature control during heavy-duty hauling operations
• Specifically engineered for Volvo VNL and VNM truck cooling system applications
• Prevents air ingestion when installed during routine cooling system service or repair

Volvo Engine Coolant Expansion Tank

Maintain optimal thermal management in your D11, D13, or D16 engine with this genuine Volvo Engine Coolant Expansion Tank. Unlike a simple overflow bottle, this tank is a critical pressure-vessel engineered to manage the high-velocity coolant flow and thermal expansion of heavy-duty engines. The Volvo 23915461 features reinforced mounting points and integrated ports for the coolant level sensor to prevent "low coolant" dash errors and engine derate conditions. Replacing a crazed, leaking, or discolored expansion tank with this pressurized expansion tank ensures the system remains airtight, preventing the localized boiling and liner pitting caused by pressure loss.
