Troubleshooting & FAQ
How do I know if the injector sleeves need replacing?
Common signs of a failing injector sleeve include coolant contamination in the fuel, milky or discolored engine oil, unexplained coolant loss, and engine overheating. A pressure test of the cooling system can help confirm a leak.
Is this kit compatible with my specific D4 engine model?
This kit is designed for a broad range of Volvo Penta D4 and D6 engines. To ensure a perfect fit, please cross-reference your engine's model number and the OEM part number (889970 or 23579368) with the compatibility table provided on this page.
What tools are required for installation?
Installation requires standard mechanic's tools as well as specialized tools for injector sleeve removal and installation. Due to the precision required, we recommend the job be performed by a qualified marine mechanic.

Injector sleeve failure can be caused by age, corrosion from poor coolant quality, engine overheating, or improper installation. Using high-quality coolant and ensuring the engine operates within its normal temperature range can extend their life.
