Description
Quickly Plug Leaks. Prevent Overheating. Protect Your Engine.
BG Universal Cooling System Sealer PN 511 is a professional-grade cooling system treatment that quickly and completely plugs leak points in the coolant system to help prevent overheating and coolant loss. Its advanced fiber-based formula circulates throughout the cooling system, locating and sealing minor leaks before they become major repairs.
Unlike traditional stop-leak products that may clog cooling system components, BG Universal Cooling System Sealer utilizes ultra-fine sealing fibers that are six to ten times smaller than the passages found in radiators and heater cores. These fibers safely travel through the system and concentrate only at leak points, forming a durable, long-lasting seal.

Why Use BG Universal Cooling System Sealer?
Even small coolant leaks can lead to reduced cooling efficiency, coolant loss, and engine overheating. Left untreated, leaks can grow larger and result in expensive repairs to radiators, heater cores, hoses, and other cooling system components.
BG Universal Cooling System Sealer quickly seals leak points and helps restore cooling system integrity, allowing your engine to maintain proper operating temperatures and reliable performance.
Advanced Fiber Technology
The specialized sealing fibers in BG Universal Cooling System Sealer are engineered to circulate freely through the cooling system without restricting coolant flow. Once a leak is located, the fibers bond together to create a permanent-style patch that helps stop leaks and restore system performance.
