781-121EX-1 — Volvo Fh4 / Fm4 Headlamp Washer Pump (Dual Outlet)

This is a dual-outlet headlamp washer pump designed to supply washer fluid to the headlamps on Volvo FH4 and FM4 series trucks. It operates by drawing fluid from the reservoir and pressurizing it through the washer nozzles. A malfunctioning pump will result in no washer fluid being sprayed onto the headlamps, impairing visibility during adverse weather conditions.

Failure Symptoms

The primary symptom of a failed headlamp washer pump is the complete lack of washer fluid spray onto the headlamps when activated. If the pump motor is failing, you might hear unusual noises like grinding or buzzing. Continued operation without functional washers can lead to reduced visibility in rain or snow, increasing driving risk.

Installation Tip

Ensure the electrical connector is clean and securely attached before installing the pump to guarantee proper power supply. Avoid submerging the pump motor in washer fluid during installation, as this can lead to premature failure.

Service Note

Check the washer fluid level and inspect the washer lines and nozzles for blockages when replacing the pump.
