Original windshield washer fluid reservoir. Will fit 1984-1988 Toyota Pickups and 1984-1989 4Runners.
Used in good condition. Cap is missing some plastic. Motor is missing. Seal around motor is a little chewed up and may need replacing. New aftermarket motors are available if this one does not work. See pictures for condition details.
Only way to keep these from cracking is to make sure it always has fluid in it. Do not use straight water as it will clog your lines and squirters (calcium buildup from hard water). Washer fluid is around $3 at walmart.
