How to Replace Windshield-Washer Tubing in a Toyota Highland

Buy tubing or tubing/valve assemblies specifically made for the Highlander SUV. Avoid the one-size-fits-all assembly as it will not fit properly.

Find the Highlander's windshield washer reservoir tank on the passenger's side front, directly behind the headlight and in front of the engine coolant tank.

Disconnect the tubing at the windshield side first and drain the remaining fluid into a separate container for disposal.

Detach the tubing from the bottom end of the reservoir. You'll need to be underneath the Highlander to reach this connection. Remove the front quarter panel, if necessary.

Connect the new tubing to the washer reservoir, then the windshield outlets.

Fill the reservoir with fresh washer fluid and test the wipers. You might notice that it takes a few minutes to prime the new tubing before you see washer fluid coming out onto the windshield.
