Troubleshooting & FAQ
How do I confirm this kit fits my engine?
This kit is specifically for Volvo Penta AQD32A (1969–1977) and MD32A (1970–1977) models. Verify your engine model and year falls within this range. Cross-reference the OEM part number 875439 with your service manual.
What are the signs of a failing oil pan gasket?
Common signs include visible oil leaks or drips underneath the engine, a coating of oil grime on the bottom of the oil pan, and a consistently low engine oil level that requires frequent top-offs.
Is this a complete kit for the job?
Yes, this is a comprehensive sump conversion kit that includes the main oil pan gasket and other required seals to complete the installation on compatible models.
Can I reuse my old oil pan bolts?
It is generally acceptable to reuse old bolts if they are in good condition (no stripped threads or corrosion). However, always follow your engine manufacturer's service manual recommendations, as some may advise replacement.
