Will this pump work with my existing washer fluid reservoir and hoses?

Yes. This pump is designed to connect directly to Rio sedan factory reservoir and line connections — no modification to fluid plumbing needed.

Do I need to drain the washer fluid before installation?

Draining isn't required, but it makes the swap cleaner. Most buyers disconnect the pump, empty residual fluid, and swap in the new assembly in under 15 minutes using basic hand tools.

What if the pump doesn't spray right after I install it?

Air pockets in the line are common after a pump swap. Activate the washer spray 5–10 times in short bursts to purge air and prime the system. Pressure should normalize within a few cycles.
