Removing fuel injectors, in the event that they are stuck in the cylinder head

Special tools, testers and auxiliary items required







- Tool set with puller T10133 Tool Set T10133

Remove intake manifold and fuel rail.







The illustration shows the fuel injector.
1 - Radial compensation, replace if damaged
2 - Combustion chamber sealing ring (Teflon sealing ring). Replace the sealing ring once removed. The sealing ring must not be greased or handled with any other lubricants when installing.
3 - Groove on fuel injector
4 - Spacer ring, replace if damaged
5 - O-ring (replace, coat lightly with clean engine oil when installing)
6 - Support ring (via this support ring, the fuel rail utilizes the force to hold the fuel injector in place in the cylinder head).







NOTE: With fuel injector installed, the radial adjustment - 1 - is clipped into the support ring - 6 - . To remove the fuel injector, the support ring must be separated from the fuel injector in order to install the puller T10133/2 into the indentation on the fuel injector - 3 - .

- Cover open intake channels with a clean rag.
- Disconnect electrical harness connector at fuel injector that is to be removed.







- Bend retaining tabs of radial compensation to the side using a screwdriver and pull off support ring from fuel injector.







- Assemble the slide hammer T10133/3 - 1 - and the injector puller T10133/2 - 2 - . Then, guide the puller T10133/2 into the groove on the fuel injector and carefully drive the fuel injector out. It is possible that this will destroy the radial compensation (retaining tabs break). This must be replaced when re-installing fuel injector.

NOTE: The combustion chamber seal must always be replaced before re-installing the fuel injector.
