Description
Electric power steering pump for CITROËN C8, JUMPY 2, Peugeot 807, Expert 2
Fully functional – tested
Comes with a piece of wiring
This electric power steering pump is a direct-fit replacement option for a range of Stellantis MPVs and light commercial vehicles. It restores hydraulic assistance to the steering system using an electric drive, improving low-speed maneuverability and steering comfort. The unit is commonly searched by part number (A5095965+C, 1400752580, 4007NJ, 1680897380), which makes it easy for workshops and DIY mechanics to find the correct item for Citroën and Peugeot models.
Features
- Electric-driven hydraulic pump designed for power-assisted steering systems.
- Supplied with a short length of wiring to aid installation.
- Fits multiple Citroën and Peugeot models—suitable as a replacement for the listed part numbers.
- Suitable for professional workshops and experienced DIY mechanics familiar with steering system servicing.
How It Works And What It Does
The pump provides hydraulic pressure to the steering system when assistance is required, especially at low speeds or during parking maneuvers. An electric motor drives the hydraulic pump, so steering assistance is available even when engine RPM is low. Proper function ensures lighter steering effort, improved vehicle control and reduced driver fatigue.
Replacement Procedure (Overview)
- Park vehicle on level surface, engage parking brake and disconnect the negative battery terminal to avoid electrical faults.
- Raise vehicle if necessary and remove protective covers to access the pump. Support the steering rack if required to relieve hose stress.
- Carefully disconnect electrical connector and hydraulic lines. Cap or plug lines to prevent contamination and fluid loss.
- Remove pump mounting bolts and extract the unit. Compare the replacement to the removed part to confirm match of connectors and mounting points.
- Install new pump, tighten mounting bolts to manufacturer torque, reconnect hydraulic lines with new seals or crush washers as required, and reconnect electrical connector.
- Refill the system with the manufacturer-recommended power steering fluid, then bleed the system according to factory procedure (centre the steering wheel, cycle steering slowly lock-to-lock, operate pump as required while monitoring fluid level and air removal).
- Check for leaks, verify steering operation at idle and during a short test drive, and re-check fluid level after final bleed.
Typical Lifespan And Service Intervals
Service life depends on vehicle use and maintenance. Units can last many years in normal use, but high-mileage or vehicles exposed to contamination, water ingress or extreme temperatures may require earlier replacement. Regular inspection of fluid condition and hoses helps extend pump life.
Installation Recommendations
- Use only the manufacturer-recommended power steering fluid—do not mix fluids of unknown specification.
- Replace sealing washers or O-rings on hydraulic connections to avoid leaks.
- Prevent contamination: cap lines immediately after disconnection and keep the system clean during installation.
- After fitting, follow a proper bleeding procedure and perform a test drive to confirm correct operation. Retorque fittings after the first road test if necessary.
- If electrical connector shows corrosion, clean or replace the connector to ensure reliable motor supply.
Most Common Failure Reasons
- Electrical Motor Wear Or Brush Failure: Internal motor components can wear over time, leading to reduced or no pump operation.
- Seal Or O-Ring Leakage: Degraded seals allow fluid loss and air ingress, causing noisy or ineffective steering assistance.
- Contaminated Or Degraded Fluid: Dirt, metallic particles or degraded fluid accelerate internal wear and can block valves.
- Connector Corrosion Or Wiring Damage: Poor electrical supply from corroded plugs or damaged wiring prevents motor operation.
- Bearing Or Mechanical Wear: Internal bearings may fail, generating noise and eventual seizure of the pump.
