Volvo Penta D4 D6 Seawater Hose Kit 22191941

Part Number: 22191941
Brand: Volvo Penta
Official Product Type: Seawater Hose Kit – Raw Water Cooling Circuit
System: Raw Water / Seawater Cooling
Supersedes: 21368516, 21368518, 21655922, 22150745

Overview

The Volvo Penta 22191941 is the genuine OEM seawater hose kit for the raw water cooling circuit on selected D4 and D6 marine diesel engines. It is located in the seawater pump and seawater filter assembly, and consolidates four earlier Volvo Penta D4/D6 seawater hose numbers into a single current replacement. If your engine currently carries 21368516, 21368518, 21655922, or 22150745, this is the documented current replacement — but confirm by engine serial number and cooling-system diagram before installation.

Compatible Applications

• Volvo Penta D4-180, D4-210, D4-225, D4-260, D4-300 (A-, D-, and I-series variants)
• Corresponding D6 applications using the same seawater pump / filter cooling circuit configuration

Volvo Penta revised this hose assembly several times across D4 and D6 production. Confirm the complete engine model, suffix, serial number, and seawater pump / filter diagram before ordering, especially where an earlier hose number is currently installed.

Serial Number & Fitment Notice

Seawater cooling hose configurations vary by engine model, suffix, and serial number range. Do not order by engine displacement alone. Confirm fitment using your complete engine model designation, suffix, and serial number against the applicable Volvo Penta cooling-system diagram.

Dimensions & Weight

Approximate weight: 1.92 kg. Exact hose dimensions and routing are not published in current Volvo Penta accessory literature — confirm by part number and serial number match to the cooling-system diagram.

When to Replace

Replace the hose assembly when it shows swelling, soft spots, cracking, abrasion, leakage, heat damage, or deterioration around its connections. Raw water hoses should also be inspected whenever servicing the seawater pump, filter, or cooler circuit. Do not reuse a hose that shows any signs of internal or external deterioration.

Installation Notes

Before installation, inspect the seawater filter, seawater pump, hose clamps, and all adjoining hose connections. Confirm that the replacement follows the original routing without kinks or contact with hot or moving components. Adjacent components in the D4/D6 seawater cooling assembly may include:

• Seawater filter (21368500 — not currently listed; contact us to source)
• Rubber hose 994814
• Hose clamps 60111132 / 961672
• Seawater pump assembly (varies by engine configuration)

Technical FAQ

Q: Does 22191941 replace all four older hose numbers?
A: Yes — 22191941 consolidates 21368516, 21368518, 21655922, and 22150745 into a single current replacement. However, always confirm by engine serial number and cooling-system diagram before installation, as hose routing and connection configurations can vary.

Q: How do I know which hose is currently on my engine?
A: Check the part number on the existing hose or look up your engine serial number in the Volvo Penta parts catalog for the seawater pump and filter assembly. Contact us with your engine serial number if you need help confirming the correct part.

Q: Should I replace the hose clamps at the same time?
A: Yes — replacing hose clamps at the same time as the hose is good practice. Reused clamps on a new hose can cause leaks if the clamp has deformed or corroded.

Q: What other cooling system parts should I inspect at the same time?
A: Inspect the seawater filter, seawater pump impeller, pump cover screws, and all adjacent hose connections. If the hose failed due to heat or age, the impeller and filter should also be checked.

Parts Desk Insights

The key detail with 22191941 is that it consolidates four older D4/D6 seawater hose numbers. If a customer references one of the older numbers (21368516, 21368518, 21655922, or 22150745), 22191941 is the documented current replacement — but the engine serial number should still be checked against the cooling-system diagram before installation, as hose routing can vary by engine suffix and production run. When a customer is replacing this hose, recommend also checking the seawater filter and impeller while the cooling circuit is open.
