Description:
PP-858541 Volvo Penta 858541 / 21710298 Power Steering Cooler
This Seakamp Power Steering Cooler is a marine-grade replacement designed for Volvo Penta marine petrol and diesel engines in sterndrive, inboard and IPS installations, most commonly fitted to the KAD43B family. It also replaces Volvo Penta part #21710298.
The power steering cooler routes hydraulic fluid through a small tube-and-shell core where raw water absorbs heat before the fluid is returned to the steering pump and reservoir. This keeps the hydraulic oil within its working viscosity range, especially during prolonged low-speed manoeuvring and trolling when fluid temperatures can otherwise climb rapidly.
Hot power-steering fluid loses viscosity and breaks down lubricants, leading to noisy pumps, premature seal failure and loss of steering assistance. Keeping fluid temperature in check preserves smooth steering feel and protects the pump, rack and hose assembly.
Manufactured to match OEM dimensions, port orientation and mounting geometry, the 858541 is a true direct-fit replacement for the original Volvo Penta component. It installs without modification to existing hoses, brackets or pipework, making it suitable for planned maintenance, corrosion replacement or preventative servicing.
