Thexton Toolworx 356 Heater Core Back Flush Tool

The Thexton Toolworx 356 Heater Core Back Flush Tool provides automotive technicians and DIY mechanics with a simple, effective solution for cleaning clogged heater cores without removing them from the vehicle. This professional-grade flushing tool connects directly to a standard garden hose, allowing you to restore proper coolant flow and heat output in minutes.

Key Features:

• Stepped adapter design fits three common hose sizes: 1/2", 5/8", and 3/4" inch
• Durable non-corrosive aluminum construction for long-lasting performance
• Connects to any standard garden hose for convenient water supply
• Built-in valve for precise flow control during flushing process
• Eliminates the need to remove heater core from vehicle

How to Use: Remove the radiator cap and drain the coolant system. Disconnect the heater hoses from the engine and insert the stepped adapter end into the hose opposite the water pump connection. Attach your garden hose to the tool, turn on the water supply, and open the valve to begin flushing. Continue until clean, clear water flows through, indicating the heater core is fully cleaned of debris and buildup.

This tool is essential for restoring heat output in vehicles with weak or no cabin heat caused by restricted heater core passages.
