Installation Notes
- Ensure the engine is completely cool and disconnect the negative battery terminal for safety.
- Remove any components obstructing access to the exhaust manifold bolts.
- Carefully remove the old bolts. We recommend spraying penetrating oil beforehand if they are rusted.
- Thoroughly clean the mating surfaces on the cylinder head and the exhaust manifold. Ensure they are free of old gasket material and debris.
- Position the new manifold gasket (not included) and the manifold onto the cylinder head.
- Apply a suitable high-temperature anti-seize compound to the threads of the new bolts.
- Hand-tighten the bolts in the sequence recommended by your engine's service manual.
- Using a torque wrench, tighten the bolts to the manufacturer-specified torque values, following the correct pattern (typically starting from the center and working outwards). Do not overtighten.
- Reinstall any components that were removed and reconnect the battery.
- Start the engine and carefully check for any exhaust leaks around the manifold.
Troubleshooting & FAQ
How do I know if this bolt kit will fit my specific engine?
This kit fits a range of Volvo Penta B18 and B20 series gasoline engines from 1968–1990s. The most reliable method is to check your engine model against our 'Engine & Model Compatibility' list and verify your current part number against the 'Part Number Matrix'.
What are the signs my existing manifold bolts are failing?
Common symptoms include a ticking or hissing noise from the engine bay that is more pronounced when cold, visible rust or corrosion on the bolt heads, or exhaust fumes being noticeable in the engine compartment.
Can I reuse my old exhaust manifold bolts?
It is strongly recommended to always use new bolts when installing an exhaust manifold. Old bolts can suffer from heat-cycle fatigue, corrosion, and stretching, making them unreliable for creating a proper seal and achieving correct torque.
Do these bolts require a special sealant or lubricant?
We recommend applying a thin layer of high-temperature anti-seize lubricant to the bolt threads before installation. This helps ensure accurate torque readings and prevents the bolts from seizing in the cylinder head, which simplifies future service.
What torque specification should I use?
Torque specifications are critical and specific to your engine model. Always consult your official Volvo Penta service manual for the correct torque values and the required tightening sequence. Incorrect torque can lead to exhaust leaks or damaged components.
