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

Yes — this pump uses standard Corolla connections. Verify your hose diameters match before assembly, but no adapters are typically needed for USA model years 98–02.

Do I need to drain my washer fluid before swapping pumps?

Recommended. Drop the fluid level as low as possible to minimize spillage when you disconnect the pump intake line from the reservoir.

What if the pump doesn't spray after installation?

Check that hoses are seated fully on the pump outlets and that your reservoir actually contains washer fluid. Air in the lines is common after a swap — run the pump for 10–15 seconds to purge. If still dry, the intake line may be blocked.
