Description
Description
A specialized penetrant spray engineered to safely free seized injectors, spark plugs, and glow plugs without damaging delicate components. Using rapid cold shock technology, it chills the area up to -40°C to break the bond between fused threads and cylinder-head surfaces. The PTFE-based lubricant reduces friction during extraction while a corrosion inhibitor protects exposed threads. Acid-free and silicone-free formula ensures safe use on sensitive engine components.
Key Features & Technical Specifications
- Cold Shock Technology: Rapidly chills area to -40°C, promoting micro-cracking of corrosion bonds
- PTFE Lubrication: Reduces friction during component extraction
- Corrosion Protection: Leaves protective film to prevent oxidation
- Safe Formula: Acid-free and silicone-free for delicate parts
- Volume: 400ml
- Application: Technical spray
- Purpose: Free seized injectors, spark plugs, and glow plugs
How to Use
- Prepare Area: Clean the work area as thoroughly as possible. Remove loose corrosion flakes with a wire brush. Disconnect any electrical wiring if safe to do so.
- Shake Can: Shake the aerosol vigorously for at least two minutes before use.
- Apply Spray: Direct the precision nozzle at the seized component. Observe the chilling effect as temperature drops rapidly.
- Allow to Work: Wait a short period for the cold shock to weaken the corrosion bond. Repeat application if necessary.
- Apply Breakaway Torque: Use appropriate tools to carefully apply force. Never touch the chilled area with bare skin to avoid frostbite.
- Work Component: When attempting to unscrew, turn the component gently in both clockwise and anti-clockwise directions to further free the bond and reduce thread friction.
- Clean Threads: Consider cleaning threads with a suitable tool before refitting the component. The product leaves an anti-corrosion film to protect exposed threads.
The JLM Injector + Spark Plug Loosener offers a safe, chemical solution to one of the most challenging workshop tasks removing seized delicate components without the risk of costly breakage.
