Replace the seals and place the reservoir assembly in your Tacoma bolting it to the upper radiator support. Reconnect the negative battery cable and fill the new reservoir with windshield washer fluid.
Tips & Warnings
Drain the reservoir into a catch pan, if there’s any fluid left in the tank, before uninstalling it.
You can buy premixed windshield washer fluid–diluted window cleaner–or make your own by adding about three cups of window cleaner per one gallon of distilled water.
Avoid frozen fluid in your windshield washer reservoir and your washer lines by using weather appropriate fluid in the wintertime that includes both cleaner and ice remover.
