Will this bolt directly to my current washer reservoir without any adapters?

Yes — this pump mounts at the factory points on your reservoir. No drilling or modification needed. Just disconnect the old pump, swap in the new one, and reconnect the hose.

Do I need to drain the reservoir before installing this?

Not required, but recommended. Draining first keeps fluid off your hands and prevents spills during swap. Install is quick either way — takes about 10 minutes.

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

Check that your hose is fully seated on the outlet nipple and your washer fluid reservoir is full. Prime the system by hitting the spray button a few times. If spray is still weak, the hose may have a kink or blockage — inspect the full line from pump to nozzles.
