99-07 Chevrolet Silverado Sierra 1500 2500 3500 Windshield Washer Pump

Will this pump work with my factory washer fluid hose?

Yes. The pump outlet matches OEM hose connections, so you can reuse existing lines. Inspect hose condition before reinstalling — cracked or brittle lines should be replaced.

Do I need to drain the washer reservoir before installation?

Highly recommended. Empty the reservoir first to avoid spilling fluid inside the engine bay. Once the pump is installed and wired, refill with washer fluid and test operation.

What electrical connections does this pump use?

The pump harness terminates in a factory-style connector designed to plug directly into your truck's washer switch circuit. No splicing or soldering required if original wiring is intact.
