🔧Lever-Action Coolant Flush Gun – Heater Core Flush Kit for Cooling System Maintenance
Flush Smarter. Clean With Control.
Make cooling-system maintenance more manageable with a lever-action flush gun designed for targeted rinsing of heater cores, radiator connections and coolant hoses.

A More Focused Way To Flush.
A basic open hose can be awkward to direct around engine components. The stepped nozzle and trigger handle help guide flushing flow into the connection you need to clean.
✓ Direct flushing flow toward accessible coolant passages.
✓ Operate the lever-action trigger from the handle.
✓ Work with suitable heater-core and radiator hose connections.
✓ Use the included connection fittings for compatible water and air lines.

Four Details That Make A Difference.
From the stepped flushing nozzle to the locking trigger, each feature is designed to make the tool easier to connect, position and operate during maintenance.
Stepped Flush Nozzle
Multiple nozzle diameters help accommodate different compatible hose openings.
Lever-Action Trigger
The hand-operated trigger provides convenient control of flushing flow.
Metal Connection Fittings
Supplied metal fittings provide connection options for compatible workshop air equipment.
Locking Trigger Latch
A metal latch can hold the trigger in position during suitable flushing operations.

Prepare. Connect. Flush.
Follow the vehicle manufacturer's service procedure and use the correct connections before beginning a cooling-system flush.
Prepare The System Switch off the engine, allow the system to cool completely and prepare a suitable drain container.
Connect Water & Air Attach compatible water and compressed-air lines using the appropriate fittings.
Check Connections Confirm that all hose fittings are secure and the supply pressure complies with service requirements.
Position The Nozzle Select a suitable nozzle diameter and position it securely at the designated flushing opening.
Flush The Passage Operate the trigger carefully and flush in the direction specified by the vehicle service procedure.
Finish & Reassemble Stop the flow, disconnect safely and complete coolant refilling and bleeding as specified.

Safety: Never open or service a hot, pressurized cooling system. Wear appropriate eye and hand protection. Use only approved pressure levels and collect used coolant for proper disposal. Refer to the vehicle service manual for the correct flushing procedure.
Upgrade Your Flushing Method.
Compared with rinsing from an ordinary open hose, this purpose-designed flush gun offers a stepped outlet and an easy-to-operate trigger for more focused maintenance work.
✓ More targeted direction: aim flow toward the opening being serviced.
✓ Convenient control: operate flow from the trigger rather than repositioning the hose.
✓ Adaptable nozzle: a stepped design accommodates a range of suitable hose openings.
✓ Workshop connections: supplied adapters help connect compatible hoses and air lines.

Frequently Asked Questions.
It is a workshop tool designed to direct flushing flow into accessible vehicle cooling-system passages. Typical applications include compatible heater-core, radiator and coolant hose maintenance. Always follow the vehicle manufacturer's service instructions.
Does this tool use both water and air? +
The illustrated tool is configured for water and compressed-air connections. The actual operating setup, pressure limits and flushing procedure must be determined from the equipment instructions and vehicle service requirements.
Will it fit my garden hose and air line? +
The product images identify a 3/4-inch garden hose connector and approximately 8 mm air fitting. Please check thread dimensions, coupling type and connection standards before purchasing.
Can it be used on every vehicle? +
Not necessarily. Compatibility depends on vehicle cooling-system design, hose dimensions, access points and approved maintenance procedures. Consult your vehicle's service documentation before use.
What should I check before flushing? +
Make sure the engine and coolant have cooled completely. Wear appropriate protective equipment, verify all fittings, confirm approved pressure limits and prepare to collect used coolant. Follow the correct refill and air-bleeding procedure afterward.
