Description:
PP-21710298 Volvo Penta Fuel & Power Steering Oil Cooler
The PP-21710298 Volvo Penta Fuel & Power Steering Oil Cooler is a compact marine-grade cooler designed for use on Volvo Penta KAD-series diesel engines, where it performs the dual function of cooling power steering hydraulic oil and, in some configurations, return fuel flow.
This cooler uses a shell-and-tube heat exchange design, with raw water circulating through an internal tube bundle while oil flows around the exterior chamber. Heat is efficiently removed from the oil before it is returned to the power steering system or fuel circuit, maintaining stable operating temperatures and protecting pumps, seals, hoses, and steering components from overheating and premature wear.
Maintaining correct oil temperature is especially critical on KAD-series engines, where high steering loads or sustained manoeuvring can rapidly elevate hydraulic oil temperatures. A properly functioning oil cooler ensures smooth steering response, consistent hydraulic pressure, and long system life in warm or high-load marine conditions.
