Volvo Penta Hose Clamp 21501238

Volvo Penta 21501238 is a genuine OEM hose clamp used in Volvo Penta cooling-system service. The strongest current public application trail places this clamp in a closed-cooling / heat-exchanger / block / exhaust assembly, where it appears as diagram item 7 in a Volvo Penta parts catalog for V8-270-C-B. In that breakdown, the clamp sits with reservoir 21429093, hose 3860590, hose 21451470, and related cooling hardware, which gives it a solid assembly-position reference for that exact hose-clamp location.

Engine Compatibility

The strongest supportable fitment trail for Volvo Penta 21501238 is by exact diagram position rather than by a broad public engine-family list. Current public catalog evidence places it in the V8-270-C-B closed-cooling assembly noted above, so the safest fitment standard is the exact Volvo Penta serial-number-based parts diagram for the engine and hose location being serviced.

Serial Number Fitment Notice

Fitment can vary by engine package, cooling layout, hose diameter, and clamp position. Confirm Volvo Penta part number 21501238 against your engine serial number and the correct Volvo Penta parts diagram before ordering, especially on engines where several nearby clamps may look similar but serve different hose sizes or routing points.

When This Part Needs Replacement

Replace this clamp when the original clamp is corroded, distorted, stripped, no longer tightening evenly, or no longer holding the hose securely at the connection. It is also a smart replacement during adjacent cooling-system hose service if the original clamp has already been removed or shows visible age-related wear.

Installation Notes

Match this clamp to the exact Volvo Penta application before installation. The strongest public reference places it in the closed-cooling assembly with adjacent hoses 3860590 and 21451470, so confirming both the part number and exact diagram location is the safest cross-check before ordering or reassembly. Inspect the hose condition and neighboring clamps at the same time to help avoid repeat leaks after service.

Alternate/Superseded Part Numbers

Use Volvo Penta 21501238 as the primary ordering number. Current public sources reviewed consistently present this exact number as the active OEM identifier for this hose clamp.

Parts Desk Insight

Small clamps are easy to overlook during cooling-system work, but a tired clamp can turn a simple hose service into a repeat leak. Matching the exact Volvo Penta diagram position first is usually much safer than trying to substitute by appearance alone.
