Liqui Moly offers advice on removing injectors

Removing injectors can be quite a feat of strength, when hardened combustion residue sticks them to the engine. Rather than using mechanical force, it is much simpler to remove them by means of chemical intelligence. The Pro-Line Injector and Glow Plug Dismantling Aid by additive specialist Liqui Moly was developed precisely for this purpose.

Liqui Moly Application Technican Reiner Schönfelder explains why injectors are so hard to remove: “Combustion gases, fuel vapours and oil mist escape from damaged seals. They form a tar-like, glass-hard residue in the attachment shaft of the injector, causing an apparently insoluble problem.”

If you try to remove this residue with a tool, components can get damaged – not least the injector itself. The result is an increase in the time and cost involved. The smarter solution is to use Liqui Moly’s Pro-Line Injector and Glow Plug Dismantling Aid.

It contains a special solvent developed precisely for this purpose. After a reaction time of 15 to 30 minutes, it softens the caked resins, oil residues and dirt crusts. The soiling is then easy to remove and the injector can be effortlessly removed, without damage. In the case of stubborn deposits, Reiner Schönfelder recommends allowing the Injector Dismantling Aid to take effect overnight. It works not only with injectors but also when removing glow plugs, too.

To avoid the problem in the first place, use the Pro-Line Injector and Glow Plug Grease for installation purposes. This high-temperature paste prevents solidification and galling, as well as providing protection from corrosion.
