Only genuine Honda power steering fluid or a known equivalent may be used when adding fluid. Acura says that ATF or fluids manufactured for use in other brands of vehicles by their manufacturers or independents are not compatible with the Honda power steering system. The use of any other fluid will cause the seals to swell and create leaks.
See Figures 1, 2 and 3
The fluid in the power steering reservoir should be checked every few weeks for indications of leaks or low fluid level. Check the fluid with the engine cold and the vehicle parked on a level spot. The level should be between the upper and lower marks. Fluid need not be added right away unless it has dropped almost to the lower mark. DO NOT overfill the reservoir.
When adding fluid, or making a complete fluid change, use only Honda Power Steering Fluid or equivalent; NEVER add automatic transmission fluid. Failure to use the proper fluid may cause hose and seal damage, and fluid leaks.
- Unscrew the cap again, then check the fluid level while holding the cap above the tip of the dipstick. If the level is at or below the ADD mark on the dipstick, add fluid until the level reaches the FULL mark. Be careful not to overfill, as this will cause fluid loss and seal damage. A large loss in fluid volume may indicate a problem, which should be inspected and repaired at once.
