21339891 Hose | Genuine Volvo Penta Part

🔧 Product Description

Genuine Volvo Penta formed coolant hose used in the D9 industrial-engine cooling and auxiliary air-compressor circuit. The hose is shown in the WABCO 704 compressor installation and in the water-pump/thermostat-housing area on related D9 engines; length and illustrated position must be checked because the same part family includes short and long connecting runs.

🔌 Function

Carries engine coolant through the assigned compressor or thermostat/water-pump connection to control component temperature.

⚠️ Common Signs of Failure

• Coolant weeping or dripping from the hose ends, often onto the compressor below
• Coolant level falling and temperature climbing under load
• Hose gone soft, swollen or spongy when squeezed cold
• Cracks opening at the moulded bends and at the clamp lands
• Inner wall found perished or delaminated when the hose is cut open

🛠️ Service Notes

• This is the 130 mm run - the same hose family also covers a much longer connection at around 775 mm, so order by installed length and illustrated position
• Confirm whether the engine carries the WABCO 704 compressor arrangement before ordering
• Fit new clamps and check the spigots for corrosion pitting
