Rarely serviced but worth inspecting

Driving a car is a way of expressing freedom for many of us. Nonetheless, turning a heavy steering wheel at low speeds such as maneuvering through parking lots is not by any means pleasant.


Heavy steering feel is often caused by mechanical failure or simply power steering fluid that needed replacement. Like the various lubricants in the engine bay, it undergoes various stresses including heat, pressure, wear and tear, with possibly foreign contaminants. A blackish murky content in the power steering fluid container indicates that it badly needs a good flushing. Here’s how to do it in the comfort of your porch.

Tools
Large syringe
Aquarium air hose (6cm – 10cm)
New power steering fluid (1 – 2 bottles)
Used news paper or rags for wiping up
Empty water bottle to hold removed power steering fluid

Steps
After connecting the air hose to the syringe, open the fluid reservoir tank and sucking the old fluid
Transfer the syringe’s content s into the bottle before repeating step 1 until its empty
Carefully pour the new power steering fluid until the maximum level, before starting the engine and turn the steering wheel lock-to-lock a few times. This will cycle the new fluid or any air pockets in the power steering line
Turn off the engine and repeat steps 1 to 3 until the fluid in the reservoir appears clear

Additional Tips
Depending on models, some cars are able to use automatic transmission fluid, ATF as power steering fluid. Do consult the car’s manual if unsure.
Many power steering fluid reservoirs have two minimum-maximum range, one when cold, the other when hot.
Certain cars with the engine started will have the power steering fluid bubbling in the reservoir as the power steering pump is activated. Thus, it is always advisable not to overfill it.
At the end of step 1, observe if there’s any visible sediments at the bottom of the reservoir. If so, inspect the connecting hydraulic hoses for cracks especially at both ends. Replace if necessary.
