Does power steering stop leak work?
On One Hand: Stop Leak Works by Revitalizing Seals.Power steering stop leak additives work by lubricating and plumping the rubber seals throughout the power steering unit. The seals can become brittle and dry over time. This causes the seals to pull away and small leaks to develop. Power steering stop leak is considered a temporary fix to give you some time before investing hundreds in repair.On the Other: Stop Leak Won’t Fix a Cracked Pump.A cracked power steering pump will not be fixed by stop leak additives. If your leak persists after adding a stop leak product, then you may have a crack or loose bolt somewhere along the power steering assembly or in the pump itself.Bottom LineConsidering the low cost for a bottle of stop leak, it is worth it to see if a bottle or two fixes the leak.
