The Acura TL uses an ATF-based fluid for its power steering rather than a dedicated non-ATF PSF in most generations.
The exact specification depends on the model year and generation. Always verify from your owner’s manual or the reservoir cap to confirm the required fluid type for your TL.
Determining the correct fluid for your TL
To avoid using the wrong fluid, follow these steps to identify the right specification for your car.
Check the year and generation
- Identify your TL’s generation: first generation (1999–2003), second generation (2004–2008), or third generation (2009–2014). Fluid requirements can change between generations.
- Use the generation as a starting point to narrow which ATF specification might apply (for example, older generations commonly used Dexron II/III-compatible ATFs, while newer generations may specify Honda/Acura DW-1 or PS fluids).
Always corroborate with official guidance rather than relying on memory, as specifications can vary within a generation by market or drivetrain.
Inspect the reservoir cap and labeling
- Look at the power steering reservoir cap or nearby labeling for the exact specification listed (e.g., Dexron II/III ATF, Honda PS Fluid, or DW-1).
- Note any branding on the cap, such as “Honda/Acura PS Fluid,” “ATF,” or “DW-1.”
Labeling can be subtle or omitted on some models, so use this in conjunction with other sources.
Consult the owner's manual or a dealer
- Open the owner's manual and search for the Power Steering Fluid section to find the recommended specification.
- If in doubt, contact a Honda/Acura dealer with your VIN to confirm the exact fluid type for your TL.
Do not guess when servicing the power steering system; using the wrong fluid can affect steering feel and harm seals.
Maintenance and best practices
Once you know the correct specification, follow these maintenance tips to keep the system healthy.
- Use only the recommended fluid type and avoid mixing fluids from different families (e.g., ATF with dedicated PSF funds).
- If topping up, match the fluid type already in the system unless you are performing a full flush with the recommended replacement.
- When flushing or replacing, follow the proper procedure described in the manual or by a qualified technician to ensure complete air removal from the system.
- Inspect for leaks and check for abnormal steering feel, noises, or stiffness after any service.
Following the correct specification and technique helps maintain smooth steering response and long-term reliability of the TL's power steering system.
Summary
In short, the Acura TL uses an ATF-based fluid for power steering, but the exact specification varies by year and generation. Check the owner’s manual or reservoir labeling, and when in doubt, consult a dealer with your VIN to confirm whether you should use Dexron II/III-compatible ATF, Honda/Acura PS Fluid, or DW-1. Adhering to the recommended fluid type and proper bleeding/flush procedures will help preserve steering performance and seal integrity.
