Diagnostic guidance. Suggested checks and possible repairs are separate from the owner's reported results.
Confirm where the fluid escapes and have the fluid level, condition, connections and possible air entry checked before authorizing a pump. Follow the actual vehicle's fluid and bleeding requirements. Reservoir overflow alone does not establish the specific pump-seal failure asserted in the reply. The pump and hoses should be evaluated on the findings rather than automatically replaced together.
Source discussion: question 1712851 https://2carpros.com/questions/power-steering-fluid-leak-23843695--1712851 Supports the reported history and outcome only. Follow-up guidance is editorial synthesis; unverified specifications and diagnoses are not adopted. HELLA: Hydraulic steering pump https://www.hella.com/techworld/uk/technical/car-electronics-and-electrics/hydraulic-steering-pump/ General fluid, connection and air-removal background. Follow the actual vehicle's procedure; this source does not confirm a pump-seal failure.
Power steering fluid leak?
The owner reported power-steering fluid escaping from the top of the reservoir during use. A contributor attributed this to air entering through a pump seal and recommended pump replacement. The owner intended to proceed, but no diagnostic measurements or repair outcome were reported.
Reported outcome: No pump replacement or successful repair was confirmed.
The thread does not document foaming, fluid specification, reservoir level, hose condition or a pump test.
