Windshield Washer Motor Pump Replacement 98510-2J500

Product Overview

The 98510-2J500 Windshield Washer Pump Assembly is a 12-volt electric pump installed directly into the windshield washer-fluid reservoir. It draws cleaning fluid from the tank and delivers it through the washer hoses to the front or rear spray nozzles, helping restore clear visibility during rain, dust, mud and other demanding road conditions.

This configuration commonly uses a twin-outlet design for vehicles equipped with both front and rear washer circuits. Its compact OE-style housing, electrical interface and fluid connections allow it to replace the original pump without modifying the washer reservoir or wiring system.

Basic Product Information

Hyundai and Kia identify the part as Motor & Pump Assembly – Windshield Washer, with part code 98510A. The lateris listed as the superseding replacement for 98510-2J500.

How the Twin-Outlet Pump Works

When the driver activates the washer switch, electrical current powers the internal motor. The motor drives a small impeller that draws washer fluid from the reservoir and pressurizes it toward the selected outlet.

On compatible vehicles, the two outlets connect to separate front and rear washer hoses. The vehicle’s washer-control circuit determines which direction or outlet supplies fluid. This integrated structure allows one compact pump to serve both washer circuits.

The pump performs three essential functions:

1. Draws fluid from the washer reservoir.

2. Produces sufficient pressure for nozzle spraying.

3. Directs fluid toward the applicable front or rear washer circuit.

Problems This Product May Help Resolve

Replacing a defective pump may solve the following problems when the pump has been correctly diagnosed:

• No washer fluid from the front windshield nozzles

• No washer fluid from the rear-window nozzle

• Front washer works but the rear washer does not

• Rear washer works but the front washer does not

• Weak or intermittent spray pressure

• Pump motor remains silent when the switch is activated

• Abnormal buzzing, grinding or clicking noises

• Washer fluid leaking around the reservoir connection

• Delayed washer-fluid delivery

• Internal pump seizure after long-term storage

• Electrical motor failure caused by moisture or corrosion

These symptoms can also result from blocked nozzles, frozen washer fluid, damaged hoses, a blown fuse, faulty wiring or a defective washer switch. The complete washer system should be inspected before replacement.

Material and Component Design

Engineering-Plastic Housing

The external housing uses moisture-resistant engineering plastic. It provides electrical insulation, low weight and resistance to common windshield-cleaning fluids. The molded body also maintains the correct position of the motor, impeller chamber, connector and outlet ports.

Electric Motor

The compact internal motor contains electrical windings, a rotating armature and corrosion-resistant metal components. It is designed for repeated short operating cycles whenever the washer switch is pressed.

Internal Impeller

The internal impeller converts motor rotation into fluid pressure. Its compact blade structure draws fluid from the reservoir and pushes it toward the outlet without requiring a separate mechanical drive.

Twin-Outlet Structure

Two fluid ports allow the pump to support front and rear washer circuits on compatible hatchbacks, wagons and SUVs. Outlet diameter, direction and hose arrangement should be compared with the original pump before installation.

Rubber Reservoir Seal

An automotive-grade rubber grommet seals the connection between the pump and washer reservoir. It helps prevent fluid leakage while holding the pump securely in position. Grommet inclusion depends on the confirmed order configuration.

Quality and Performance Control

Each production batch can be inspected for:

• Rated-voltage operation

• Motor starting response

• Fluid-flow consistency

• Outlet-pressure stability

• Front and rear outlet switching

• Electrical terminal continuity

• Operating noise and vibration

• Pump-housing appearance

• Fluid leakage at the housing joint

• Reservoir-grommet sealing

• Connector and outlet dimensions

• Final functional operation before packing

The pump is designed to provide stable washer-fluid flow under normal vehicle electrical voltage and ambient operating conditions. Proper washer fluid should always be used to reduce internal deposits and freezing damage.

Corrected Vehicle Compatibility

Fitment is determined mainly by the washer reservoir, electrical connector, outlet arrangement, vehicle body style and production date. It is not determined only by engine size.

Confirmed Hyundai Applications

The global compatibility database confirms i20 PB/PBT, i30 GD, i30 CW GD, Elantra GT GD and Santa Fe II CM applications across gasoline and diesel engines. 

Confirmed Kia Applications

The EPC listing specifically associates 98510-2J000 with the five-door Cerato/Forte body, so it should not automatically be advertised for every Forte sedan or Forte Koup. 

Vehicles Requiring Additional VIN Confirmation

The following vehicles may use the same pump design or the updated 98510-2J500, but should not be listed as guaranteed applications without checking the original pump:

• Kia Rio UB

• Hyundai i40 VF later production

• Hyundai Elantra GT later production

• Hyundai i30 later production

• Kia Mohave after 2016

• Other Hyundai or Kia vehicles using 98510-1C100, 98510-1W000 or 98510-3E000

OE and Replacement References

Numbers such as 98510-1C100, 98510-1W000, 98510-2K000 and 98510-3E000 may be covered by the later 98510-2J500 catalogue consolidation. They should not be treated as unconditional one-to-one replacements until the connector, outlet arrangement and reservoir opening are compared.

Installation Characteristics

The pump is designed for direct installation in the original washer-fluid reservoir. Installation difficulty is generally low to moderate, but access may require removal of the wheel-liner panel, bumper trim or washer reservoir, depending on the vehicle.

Installation Procedure

1. Switch off the ignition and disconnect the battery if required.

2. Drain or collect the remaining washer fluid.

3. Disconnect the electrical connector.

4. Mark the front and rear washer hoses before removal.

5. Disconnect both outlet hoses carefully.

6. Pull the original pump from the reservoir.

7. Remove and inspect the sealing grommet.

8. Clean the reservoir opening and remove deposits.

9. Install a new grommet if the original seal is hardened or damaged.

10. Fit the replacement pump into the reservoir without excessive force.

11. Reconnect the correct front and rear hoses.

12. Reconnect the electrical plug.

13. Refill the reservoir with suitable washer fluid.

14. Test both washer circuits and inspect for leakage.

Installation Precautions

• Do not operate the pump for an extended period without fluid.

• Do not reverse or mix the front and rear washer hoses.

• Never use engine coolant or aggressive solvents in the washer reservoir.

• Check for frozen fluid before assuming the pump has failed.

• Replace a cracked or hardened reservoir grommet.

• Compare the electrical connector and outlet direction before installation.

• Flush contaminated hoses and nozzles before testing the new pump.
