This fuel injector sleeve kit is designed to provide a proper seal for the fuel injector within the cylinder head, preventing combustion gases from leaking and ensuring optimal fuel delivery. Manufactured to meet rigorous Volvo and Renault truck standards, it offers superior sealing and durability over a worn or damaged sleeve that can cause hard starting or poor engine performance. Operators may experience rough idling, reduced engine power, or fuel leaks around the injector if this kit fails.
Always verify with serial number before ordering.

Inspect mating surfaces for wear before fitting. Use torque specs from service manual. Replace gaskets and seals as a set — reusing compressed gaskets causes oil leaks. Clean all oil passages with compressed air.
Always consult the OEM service manual for model-specific torque values and procedures. WhatsApp our technical team if you need fitment guidance.
Initial signs of a faulty injector sleeve kit may include rough engine idling or a slight decrease in power. If left unaddressed, fuel or combustion gas leaks can worsen, leading to increased emissions and potential damage to the cylinder head. Continued operation risks poor fuel economy and incomplete combustion.
Carefully clean the injector bore in the cylinder head before installing the new sleeve to ensure a proper seal. Avoid using excessive force when seating the sleeve, as this can damage the component or the cylinder head.
Always replace the fuel injector seals and O-rings when installing a new injector sleeve kit.
