Injector O-Ring Replacement

Model: Renault Espace MK 4 - Years 2002-2014
Part: Fuel injectors

The O-ring seal of the injector can become damaged, leading to reduced engine performance and fuel leaking from the injector seat. Replacing the O-ring is straightforward: remove the fuel line, disconnect the connector, and unscrew the injector mounting bolts to extract it from its seat. Clean both the injector and its seat thoroughly, apply the new O-ring, and reinstall the injector by reversing the steps. It is advisable to perform the same operation on the other injectors as a precaution.
