Directions
For 12-ounce bottle Check power steering fluid level. Add up to, but no more than 12 oz of this fluid. Start the engine and turn the steering wheel in both directions several times. Check fluid level, adding regular power steering fluid, if necessary, to bring reservoir to normal fill point. If leak continues after 400 miles, seals may need replacing.
For 1-quart bottle Add one bottle when topping off the power steering reservoir or when changing out the fluid in a system. Do not exceed factory recommended service level and consult owners’ manual for installation and fluid measurement procedure. It is not recommended that more than one bottle be added to a system or excessive seal swell and gasket deterioration may result.
