What It Does
This genuine OEM gasket seals coolant-pipe, heat-exchanger, oil-cooler, and related cooling-system flange connections on a wide range of Volvo Penta marine diesel engines. Because 864491 appears at different positions depending on engine model and production configuration, always match it against your specific engine schematic before installation.

Part Numbers & Supersession
- 864491 — Volvo Penta OEM part number
- VOE864491 — Standard Volvo Engineering format reference
No superseding part number should be substituted unless confirmed against your engine's serial-number break and current parts catalog.
When to Replace
Replace whenever the associated cooling-system flange or pipe connection is opened during service — particularly if the existing gasket is:
- Compressed, hardened, or permanently deformed
- Torn or damaged during disassembly
- Corroded around the sealing surface
- Showing evidence of coolant seepage
Reusing a compressed cooling-system gasket risks coolant leaks after reassembly. If the joint is already open, replacing the gasket now is significantly easier than reopening it later to correct a seep.
Installation Notes
- Clean both mating surfaces and remove all remnants of the old gasket without damaging the flanges
- Inspect mating surfaces for corrosion or distortion
- Confirm that 864491 matches the gasket shown in your engine's schematic — multiple visually similar gaskets may be used within the same assembly
- Install dry or with sealant only where the Volvo Penta service procedure specifies
- Torque associated fasteners evenly to specification
- Refill and bleed the cooling system as required
- Check the repaired connection for leakage after the engine reaches operating temperature

Parts Desk Insights
This gasket appears across a wide range of Volvo Penta diesel cooling systems — from D5 and D7 heat-exchanger assemblies to TAMD oil-cooler and coolant-pipe connections. The most common reason customers order the wrong gasket is ordering by appearance rather than by diagram position. Always confirm the diagram item number for your engine configuration. If a heat-exchanger, coolant-pipe, or oil-cooler connection is already apart, this is the time to replace it — reopening a correctly sealed joint is avoidable with a single low-cost part.
