Part Number: 859196 (alternate catalog format: 859196-8)
Brand: Volvo Penta (OEM Genuine)
Official Part Name: Gasket
Commonly Identified As: Aftercooler / heat-exchanger gasket
Replaces: 845353
Genuine Volvo Penta 859196 is an aftercooler gasket used in the aftercooler / heat-exchanger assembly on selected Volvo Penta 40-series marine diesel engines. It seals one of the aftercooler connections in the cooling assembly and is the current OEM replacement for earlier gasket 845353. The 40-series aftercooler uses several different gaskets in the same assembly — 859196 must be matched by part number, not appearance alone.
Compatible Applications
- Volvo Penta AQAD40A
- Volvo Penta AQAD40B
- Volvo Penta TAMD40A
- Volvo Penta TAMD40B
Engine Family: Volvo Penta 40-series marine diesel
System: Aftercooler / charge air cooling / seawater cooling circuit
Diagram Position: Aftercooler assembly — one of several gaskets in the cooler stack
Serial Number Requirement
Confirm fitment by exact engine model and aftercooler parts diagram before ordering. The 40-series aftercooler uses multiple gaskets in the same assembly — including 859047, 859131, and 859196 — each in a specific position. Match by part number, not by size or appearance.
Superseded / Alternate Part Numbers
- Current OEM: 859196 / 859196-8
- Replaces: 845353
When to Replace
- Whenever the aftercooler joint is disassembled for any reason
- When the existing gasket is compressed, torn, hardened, or shows signs of coolant or seawater leakage
- During any aftercooler service or heat-exchanger overhaul on AQAD40 or TAMD40 engines
Installation Notes
- Clean mating surfaces thoroughly before installing the new gasket
- Inspect all other sealing components in the aftercooler assembly at the same time — particularly gaskets 859047 and 859131 and any associated sealing rings around the cooler insert
- Match each gasket to its correct diagram position — do not substitute by appearance
- Refer to the Volvo Penta service manual for the applicable engine before assembly
Parts Desk Insights
This gasket comes up most often during aftercooler service on AQAD40 and TAMD40 engines — typically when a coolant leak is traced to the aftercooler stack or during a scheduled overhaul. The most common issue is ordering by size or appearance and getting the wrong gasket, since several similar-looking seals are used in the same assembly. Always ask the customer for the engine model and serial number, and confirm the diagram position before ordering. If the aftercooler is coming apart for any reason, it is worth having all three gaskets — 859047, 859131, and 859196 — on hand so the assembly is not reopened after the fact.
