Do I need to drain the old fluid before removing the pump?

Yes—drain your washer fluid reservoir first. You can siphon it out or tip the vehicle to let it run out. Prevents spills in the engine bay and keeps your work area clean.

Will this pump work if I have an aftermarket windshield washer fluid additive?

Standard washer fluid additives won't cause problems, but check that your fluid isn't overly thick or laden with sediment. Use clean, fresh fluid after install to avoid clogging the new pump.

What hardware do I need to install this?

The pump bolts to the reservoir with factory fasteners already on the reservoir itself. Verify your old hardware is reusable before removal—if corroded, grab new fasteners that match the original size.
