Then look up the torque spec for that fitting. If you find that, simply replace the O-ring. Remove the fitting and check the O-ring for splits and cracks. If you’ve had work done on your power steering and it’s now leaking at a fitting, chances are the fitting is either over or under-tightened. That causes the O-ring to split and leak. DIYers and pros often overtighten O-ring fittings. However, if the fitting uses an O-ring, tightening may make it worse. If the line has a flared fitting and the leak is at the fitting, try tightening the fitting. The steel portion of the power steering lines seals at the pump and the steering gear with either a flared fitting or an O-ring. Never use power steering stop leak to fix a leak in a return line the rubber is too aged and deteriorated and the stop leak won’t fix the leak for long Power steering leak at the fittings or O-rings But there are ways to replace just the leaking rubber portion by splicing in a new section, as long as the leak isn’t at a crimp connector. It’s usually cheaper to just replace the entire line.
Age and heat can deteriorate the rubber portion. Since this is a low pressure line, car makers usually use a low pressure rubber hose. Leaking power steering return lineĪfter the fluid has been pumped through the steering gear, it returns to the reservoir through the return line. The line must be replaced or a new section installed.įor more information on splicing in a new section of hose, see this postĪll power steering fluids aren’t the same and there’s no such thing as a “universal all-makes, all-models power steering fluid.” See this post to learn about the differences in power steering fluids. A high pressure power steering line leak can never be fixed with a stop leak product there’s just too much pressure in that line for a stop leak product.
Over time, that pressure can cause leaks at the crimp connector where the rubber hose meets the steel line. Here are the most common sources for a fluid leak: Power steering leak causes Leaking power steering high pressure lineĪ high pressure power steering line can reach pressures up to 2,000-psi. If you discover the fluid level is down, chances are you have a power steering fluid leak. You should never have to add power steering fluid to the reservoir since it’s a closed system. The fluid is pumped at high pressure through steel/rubber lines to the steering gear. Power steering uses a hydraulic fluid to operate the steering gear.
