Overview
The Volvo Penta 22369744 is a genuine OEM end cover for the heat exchanger or oil cooler assembly on selected Volvo Penta D4 and D6 marine diesel engines. It seals and completes the end of the heat exchanger assembly, maintaining the integrity of the cooling circuit. At $484, this is a precision cooling system component — confirm fitment by engine model and serial number before ordering.

When to Replace
Replace the end cover when it is cracked, warped, leaking, corroded, or damaged during service, or when it no longer provides a reliable seal in the heat exchanger or oil cooler assembly. If the heat exchanger is already open for service, replacing a tired end cover at the same time is good practice — a fresh cover is far less costly than chasing a cooling leak after reassembly.
Installation Notes
Inspect the sealing surface, gasket or O-ring area, and surrounding heat exchanger or oil cooler housing before installation. Replace any O-rings or seals that were disturbed during disassembly. Confirm the new cover matches the original by part number before installation. Follow the applicable Volvo Penta D4/D6 cooling system service procedure for assembly and torque specifications.

Technical FAQ
Q: What does the heat exchanger end cover do?
A: It seals and closes the end of the heat exchanger or oil cooler assembly, maintaining the integrity of the cooling circuit. A cracked or leaking end cover allows coolant or raw water to escape, leading to overheating or contamination.
Q: Does 22369744 replace 3595407?
A: Yes. 22369744 is the current Volvo Penta OEM part number that supersedes 3595407.
Q: Should I replace the O-rings at the same time?
A: Yes — always replace the O-rings and seals at the end cover mating surfaces when replacing the cover. Reusing old O-rings on a new cover is a common cause of post-service leaks.
Q: How do I confirm this is the right end cover for my engine?
A: Confirm by engine model and serial number using the Volvo Penta D4/D6 cooling system diagram. Contact us with your engine serial number if you need confirmation before ordering.
Parts Desk Insights
If the heat exchanger is already open for service, this is a part worth replacing when the original looks tired rather than hoping it seals one more time. A fresh end cover is far less costly than chasing a cooling leak after everything is back together. Always replace the O-rings at the end cover mating surfaces at the same time — reusing old O-rings is one of the most common causes of post-service cooling leaks on D4 and D6 engines.
