00-06 Toyota Tundra Cold Climate Windshield Washer Pump White

Will this pump work with my existing washer fluid reservoir?

Yes—this pump mounts directly into your stock washer fluid reservoir without modification or adapter fittings. Just swap the old pump out and seat this one in.

What makes a "cold climate" pump different from a standard one?

Cold climate pumps use a different internal design to prevent washer fluid from thickening or freezing at the nozzles. You get consistent spray pressure even in subfreezing conditions, where a standard pump would lose pressure or clog.

Do I need to drain or refill the reservoir during installation?

Drain the reservoir completely before pulling the old pump out. This prevents spilling washer fluid into the engine bay and gives you a clean swap. Refill after the new pump is seated and connection hoses are secure.
