21515329 Injector Sleeve | Genuine Volvo Penta Part

🔧 Product Description

A genuine injector sleeve kit used to seal and support the unit injector within the cylinder head on selected Volvo Penta D13, D16H and TAD9 engines. The sleeve isolates the injector bore from the engine coolant and combustion area, preserving correct injector seating and preventing cross-contamination.

• Volvo Penta TAD1380-82GE
• Volvo Penta TAD1180-83VE
• Volvo Penta TAD1381-85VE
• Volvo Penta TAD1384-85VE-IWP

• Engine Family: TAD

• Year Range: Approximately 2005 - 2020 production-era applications

⚙️ Key Features

• Genuine Volvo Penta injector-sleeve service kit
• Restores the injector bore sealing surface
• Separates the injector from the cylinder-head coolant jacket
• Supports correct injector seating and heat transfer
• Suitable for cylinder-head repair when the original sleeve leaks or is damaged
• Engine type: Inline six-cylinder turbocharged diesel with electronically controlled unit injectors

🔌 Function

Provides the sealed bore in which the injector is installed, preventing coolant from entering the injector well or combustion leakage from reaching the cooling system.

⚠️ Common Signs of Failure

• Coolant collecting around an injector
• Unexplained coolant loss with no external leak
• Fuel, combustion gas or soot contamination in the cooling system
• Hard starting, white smoke or uneven running
• Injector sealing failure after cylinder-head overheating

🛠️ Service Notes

• This sleeve kit fits the TAD13 engines listed (TAD1380-82GE, TAD1180-83VE, TAD1381-85VE, TAD1384-85VE-IWP) — check the exact engine type before ordering, as injector sleeves are not shared across every TAD range
• Fitting needs the correct drift and reamer for the bore, and injector protrusion must be checked and set once the sleeve and injector are installed
• Renew the sleeve whenever coolant is found in the injector well or in a cylinder's combustion chamber, since a leaking sleeve cannot be repaired in place
