Generally, the TLX uses a cartridge-style oil filter housed in a canister on the engine’s passenger side near the firewall; it is not a traditional spin-on filter in the oil pan. Access usually requires removing the engine cover and possibly a few protective panels, and some years may need the front undertray removed for easier reach.
Where to look by engine configuration
The TLX has different engine options over its model years. Here are the typical locations and access tips for the common configurations.
TLX with the 2.0 L turbo engine
The oil filter in this configuration is located in a cartridge-style housing on the engine’s passenger side, generally toward the firewall. Access is usually from the top after removing the engine cover and any nearby intake components; some models may require removal of a splash shield to gain clearance.
- Look for a round or rectangular filter housing with a removable cap or cover on the side of the engine block near the firewall.
- Inside is a replaceable cartridge filter; you’ll replace the cartridge and seal, then reseal the housing and reinstall components.
For 2.0 L turbo TLXs, always confirm the exact location in your vehicle’s service manual or with a dealer, as minor differences can occur between model years.
TLX with the 2.4 L i-VTEC engine
The oil filter in this configuration is also housed in a cartridge-style canister on the engine’s passenger side, typically accessible from above after removing the engine cover and ductwork. Depending on year, a splash shield may need to come off for better access.
- Identify the filter housing on the engine’s side near the firewall; the cap or cover will allow you to extract the old cartridge.
- Replace with a new cartridge and gasket, then reseal and reassemble the surrounding components.
As with the turbo model, exact placement can vary by year and trim, so consult the owner’s manual or service manual for your specific TLX.
How to replace the oil filter safely
If you decide to replace the oil filter yourself, here are the general steps you’d follow for a cartridge-style filter common in the TLX. Always verify procedures for your exact year/model before starting.
- Prepare the workspace: park on a flat surface, engine cool, gather the new cartridge filter, replacement gasket, the correct engine oil, a drain pan, and the appropriate tool for the filter cap.
- Gain access: remove the engine cover and any necessary ducting or shields, and, if needed, the front splash shield to reach the filter housing.
- Drain and protect: place a drain pan under the housing to catch any oil that spills when you remove the cap or cartridge.
- Remove the housing cap: carefully loosen and remove the filter housing cap or retaining ring to access the used cartridge.
- Replace the cartridge: remove the old cartridge, wipe the housing interior, install the new cartridge, and lubricate the new gasket with a thin coat of fresh oil.
- Reassemble: reinstall the housing cap with its gasket, torque to specification, and reassemble any covers or shields you removed.
- Refill and check: refill the engine with the correct amount and grade of oil, run the engine, and check for leaks around the filter area. Dispose of the old oil and filter properly.
Note: If your TLX uses a spin-on filter in your market, the procedure will differ slightly (the filter will be threaded on like older designs). Always follow your owner's manual for the exact steps and torque specs.
Safety and maintenance reminders
Always work on a cool engine and use appropriate PPE. Properly dispose of used oil and the filter at an authorized recycling facility. If you’re not comfortable performing the replacement, a dealership or qualified mechanic can handle it quickly and correctly.
Summary
The Acura TLX generally hides its oil filter in a cartridge-style housing located in the engine bay on the passenger side near the firewall. Access typically requires removing the engine cover and possibly a shield or undertray. Replacement involves swapping the cartridge and gasket, resealing the housing, and refilling the engine oil, with exact steps varying by year and engine type. Always consult the vehicle’s manual or a trained technician for your specific model to ensure proper procedure and torque specifications.
