Complete coolant flush solution for cars and tankless heaters

Meet the Fatyehx Coolant Flush Gun Kit, a complete, ready-to-use system designed to simplify backflushing and deep-clean cooling lines. The heart is a lever-action gun that delivers both air and water power, enabling you to switch from light rinse to high-pressure backflush with a simple squeeze. A locking latch helps you flush continuously without fatigue, so you can focus on monitoring flow and progress.

What you get

• One Fatyehx coolant flush gun
• Two transparent garden hoses
• Multi-size nozzles 19, 29, 32, 36.5, 40 mm
• PTFE tape
• Two clamps

The kit ships with everything you need, including hoses and a hose connector that fits standard garden taps, plus a 1/4 inch air inlet for workshop lines. The see-through hoses let you visually track fluid movement as you work, making it easier to judge when the line is clearing and when the system is flushing clean.

Dual-power flushing for thorough cleaning

With air and water power combined, the setup delivers a deeper backflush that helps remove sludge, rust, and mineral buildup from the radiator, heater core, and related pathways. The lever action lets you alternate between different modes to suit the task and the system's response.

• Forward flush with clean water to push contaminants toward the drain
• Backflush mode to dislodge deposits and restore flow
• Air-assisted blasts for stubborn debris

Designed for compatibility, the kit supports hoses from 19 to 40 mm and works with standard 3/4 inch garden hoses. The included PTFE tape helps you seal connections robustly so the process remains tidy and efficient.

Versatility and best-use scenarios

Beyond automotive coolant maintenance, this tool is well suited for AC system upkeep, piping lines in small workshops, and even flushing certain water heater configurations. It serves as a dependable all-in-one solution for hobbyists, DIYers, and professionals alike.

• Automotive cooling system maintenance and heater core cleaning
• AC evaporator and line management
• Tankless water heater flushing and general flushing tasks

Setup is straightforward: connect the hoses to a water tap and an air line, choose the matching nozzle, and begin. The tap and thread seals stay leak-free thanks to the PTFE tape, making it a practical addition to any toolbox. The Fatyehx kit aims to provide a straightforward, efficient workflow without overpromising results; use it to explore cleaner flow and potential improvements in system performance.
