Genuine 30720308 Lower Engine Oil Cooler Line V8 OEM Replacement

The Genuine Volvo 30720308 is the OEM lower engine oil cooler line engineered specifically for Volvo V8-powered vehicles. This coolant-carrying hose connects the engine oil cooler to the cooling system, allowing engine oil temperatures to be regulated through the radiator circuit — protecting the engine from heat-related oil degradation and wear.

As a Genuine Volvo OEM part, this line is manufactured to the exact factory specifications used during original vehicle assembly, ensuring a precise fit, proper flow characteristics, and long-term durability. It is the direct replacement for the lower oil cooler line position and is sold as a single unit.

Key Features:

• Genuine Volvo OEM factory part — not aftermarket
• Lower engine oil cooler line (pairs with upper line 30720307)
• Engineered for V8 engine applications
• Ensures correct oil temperature regulation via the engine cooling circuit
• Direct OEM fit — no modification required
• Manufactured to factory tolerances for leak-free, long-lasting performance

This part is sold individually. For a complete oil cooler line service, consider replacing both the lower (30720308) and upper (30720307) engine oil cooler lines at the same time.
