Application Lubricant or Fluid
3-2Lubricants and Fluids
API CERTIFICATION SEAL
For details of the lubrication points and the type of lubricants to be applied, refer to the illustrated index and the various work procedures (such
as Assembly/Reassembly, Replacement, Overhaul, Installation, etc.) contained in each section.


A Engine Acura Motor Oil:
K20Z2: P/N CA66808 (5W-20)
K20Z3: P/N CA66807 (5W-30)
Look for the API certification seal on the oil container. Make sure it says ‘‘For
Gasoline Engines.’’ SAE viscosity: See chart.
B Manual transmission Acura Manual Transmission Fluid (MTF): P/N 08798-9033C Always use Acura MTF. Using motor oil can cause stiffer shifting because it
does not contain the proper additives.
Automatic transmission Acura Automatic Transmission Fluid (ATF-Z1): P/N CA66704 Always use Acura ATF-Z1. Using a non-Acura ATF can affect shift quality.
C
D Brake system (including VSA lines)
Clutch system (manual transmission) Honda DOT 3 Brake Fluid: P/N 08798-9008
Always use Honda DOT 3 Brake Fluid. Using a non-Honda brake fluid can
cause corrosion and decrease the life of the system.

K Brake booster clevis pin

Caliper piston seal and boot, caliper pins and boots Honda Silicone Grease: P/N 08C30-B0234M
N Air conditioning compressor Compressor Oil: SP-10 (P/N 38897-P13-A01AH) for refrigerant HFC-134a (R-134a)
O Cooling system Honda Long Life Antifreeze/Coolant Type 2: P/N CA66688

MAINTENANCE MINDER INDICATOR
INFORMATION DISPLAY
SEL/RESET BUTTON
The maintenance minder is an important feature of the information display. Based on engine and transmission
operating conditions, the Acura CSX’s onboard computer (ECM/PCM) calculates the remaining engine oil and the
automatic transmission fluid life. The system also displays the remaining engine oil life along with the code(s) for
other scheduled maintenance items needing service.

Maintenance Main Items
If the message ‘‘SERVICE’’ does not appear more than 12 months after the display is reset, change the engine oil every
year.
NOTE:


 Replace the brake fluid every 3 years independent of the maintenance messages in the information display.
Inspect idle speed every 160,000 miles (256,000 km).
Adjust the valves during services A, B, 1, 2 or 3, only if they are noisy.

















A Replace engine oil (see page 8-10).
Engine oil capacity without oil filter:
K20Z2: 4.0 L (4.2 US qt)
K20Z3: 4.2 L (4.4 US qt)
B Replace engine oil and oil filter (see page 8-11). Engine oil capacity with oil filter:
K20Z2: 4.2 L (4.4 US qt)
K20Z3: 4.4 L (4.6 US qt)
Check front and rear brakes (see page 19-3). Check pad and disc for wear (thickness), damage, and cracks.
Check calipers for damage, leaks, and tightness of mounting bolts.
Check parking brake adjustment (see page 19-7). Check the number of clicks (8 to 10) when the parking brake lever is pulled with 196 N (20 kgf,
44 lbf) of force.
Inspect tie-rod ends, steering gearbox, and gearbox boots (see page 17-5). Check steering linkage.
Check boots for damage and leaking grease.
Check fluid lines for damage and leaks.
Inspect suspension components (see page 18-3). Check bolts for tightness.
Check condition of ball joint boots for deterioration and damage.
Inspect driveshaft boots (see page 16-4). Check boots for cracks and boot bands for tightness.
Inspect brake hoses and lines including VSA lines (see page 19-37). Check the master cylinder and VSA modulator-control unit for damage or leakage.
Inspect all fluid levels and condition of fluids. Engine coolant (see page 10-7)
Automatic transmission fluid (ATF-Z1) (see page 14-231)
Manual transmission fluid (MTF)
5M/T (see page 13-5), 6M/T (see page 13-82)
Clutch fluid (see page 12-7)
Brake fluid (see page 19-9)
Windshield washer fluid (see page 22-234)
Inspect exhaust system: K20Z2 (see page 9-13), K20Z3 (see page 9-14)
Check catalytic converter heat shields, exhaust pipes, and muffler for damage, leaks, and tightness.
Inspect fuel lines (see page 11-326) and connections (see page 11-328). Check for loose connections, cra cks, and deterioration; retighten loose connections and replace
damaged parts.
NOTE: According to state and federal regulations, failure to do the maintenance items marked with an asterisk ( ) will
not void the client’s emissions warranties. However, Acura recommends that all maintenance services be done at the
recommended interval, to ensure long-term reliability.
