Frequently asked questions
Can I put stop leak into electric power steering?
A fully electric steering system has no hydraulic steering fluid to treat. Follow the vehicle’s diagnostic procedure for warning lights or steering faults.
Can stop leak fix a broken power steering hose?
A damaged hose or fitting needs the appropriate repair. Have the source of an active leak identified before using an additive.
Does every hydraulic steering system take the same fluid?
Check the exact vehicle specification. Some systems require a particular steering fluid, approved ATF or other dedicated hydraulic fluid.
What if steering suddenly becomes heavy?
A sudden change in steering effort needs prompt inspection. Follow the owner’s manual and keep the vehicle parked if steering is abnormal.
