Professional Parts SWEDEN 87438200 Coolant Breather Pipe

The Professional Parts SWEDEN 87438200 is a coolant breather pipe designed to facilitate proper coolant circulation between the expansion tank and engine in Volvo vehicles. This essential cooling system component allows coolant to transfer from the engine to the expansion tank as temperatures rise, and return to the cooling system as the engine cools down.

Key Features:

• Direct replacement for OEM part number 31368200
• Connects expansion tank to engine for proper coolant flow
• Engineered to meet or exceed OEM specifications
• Heat-resistant construction designed for long-term durability
• Backed by 24-month/24,000-mile warranty

Function: As your engine heats up, coolant expands and pressurizes the cooling system. Excess coolant travels through this breather pipe to the expansion tank where it's stored until needed. When the engine cools, the contracting coolant creates a vacuum that draws coolant back from the expansion tank through the breather pipe, maintaining optimal cooling system pressure and preventing overheating.

Professional Parts SWEDEN designs replacement parts specifically for Volvo and Saab vehicles, offering OEM-quality components at competitive pricing. This coolant breather pipe provides reliable performance and proper fitment for a straightforward installation.
