Honda Civic Power Steering Seal Leak: What to Check For

Honda Civic Power Steering Seal Leak Problem

Power steering fluid leak in Honda Civic might be one of the hardest or mysterious leaks you can ever experience with your car. The fact that you may have never considered how the power steering system works will make you think maybe it’s an engine leak. Honda Civic hydraulic systems are generally robust hence chances are it hasn’t leaked before. Different power steering systems use different fluids primarily based on the design of the pump but the purpose is always the same. Regardless of the design of your car system, there are key areas where you should inspect if you hear your engine whining especially when you turn the steering wheel and Honda Civic models are no exception.

The Main Pump

Since the steering pump is the heart of the whole system, it has high chances of experiencing leakage due to constant pressure and friction on the rubber seals. Most of the time, Honda Civic power steering seal leak occurs where the pump shaft exits the fluid pump and is coupled to the pulley. If this area is the culprit, you will find the power fluid dripping from the rear of the pulley pump. This might be an indication of damaged bearings. The best solution is to replace the whole pump to avoid pump failure in the future. It is relatively an inexpensive service.

Power Hoses

The tubing or rubber pipes that carry the power steering fluid to your steering rack or gears may also be the cause of the leak. Be sure to inspect the hoses during Honda Civic power steering seal leak replacement. The rubber hose is most likely to crack where it is coupled to the metallic surface of the pump or the rack. However, you should inspect the whole length to determine if the pipes need replacement. If the pipe is damaged at one end and is long enough, cut the damaged part carefully and screw it back. Ensure you tighten the connection too.

Steering Rack

When conducting Honda Civic power steering seal leak inspection, the rack or gears connection are key areas that you should not overlook. The seals at these connections are relatively exposed to road dirt and grim which wears them out. The shaft is also damaged by the dirt due to constant friction and the small gaps or spaces becomes an escape route for the steering fluid. Key points to inspect in Honda Civic where the fluid leaks in this connection are: the point where the gear and steering column are attached, where the pitman shaft is attached at the bottom of the engine and finally where the rod is connected to the rack.

The Cooler System

Honda model cars are fitted with power steering cooler systems too. When carrying out Honda Civic power steering seal leak inspection, be sure to scrutinize these connections. The cooling system has its advantages but when it comes to fluid leakage, it complicates the inspection and repair. The cooler and its plumbing connections are mounted at the top of the engine so it won’t be difficult to spot them. Check the seals for any wear and the hoses for any cracks.

The Reservoir Tanks

Though it hardly gets damaged, you should take a closer look at the reservoir tank if you have had a look at the components above during Honda Civic power steering seal leak examination and can’t find the source of the problem. Ensure the seals are in good condition and the fluid is at the required level. Seal damage at the reservoir tank are the easiest to fix or replace.


It is important you carry regular inspection because driving your car with low power steering fluid may completely damage the whole system. You will be able to spot the issue in time and have it repaired. Finally, know the color and smell of the power fluid that your engine use as this will help you notice there is a leak immediately you spot the leak or feel the smell.
