Will this pump fit into my existing reservoir without draining it first?

You'll need to drain or lower fluid level before removal. The pump sits inside the tank, so access requires clearing most of the existing fluid. Plan for a small spill regardless.

Do I need any special tools or connectors to install this?

The pump connects to the factory wiring harness and hose fittings inside your reservoir. A small socket set and basic hand tools are all you need; no special connectors required. It's a straight bolt-in replacement.

What happens if the spray pressure feels weak after installation?

Check that hoses are fully seated on the pump outlets and that your washer fluid reservoir isn't clogged at the intake. If pressure is still low, the pump may be defective — contact support for a replacement.
