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)

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.

NOTE: If the oil pressure warning indicator stays on
with the engine running, check the engine oil l
evel. If
the oil level is correct do the following test:
1. With the engine stopped, remove the oil pressure switch (see page 8-9), then install an oil pressure
gauge (A).
2. Start the engine. Shut it off immediately if the gauge registers no oil pressure. Repair the problem
before continuing.
3. Allow the engine to reach operating temperature (fan comes on at least twice). The pressure should
be:
4. If the oil pressure is out of specifications, inspect these items:
 Blocking of oil filter (see page 8-11).
 Blocking of oil screen.
 Inspect the oil pressure relief valve (see page 8-15).
 Inspect the oil pump (see page 8-17). 1. Warm up the engine.
2. Remove the drain bolt (A), and drain the engine oil.
3. Reinstall the drain bolt with a new washer (B).
4. Refill the engine with the recommended oil
(see page 3-2).
Do not overtighten.

Frequent inhalation of brake pad dust, regardless of material composition, could be hazardous to your health.  Avoid breathing dust particles.
 Never use an air hose or brush to clean brake assemblies. Use an OSHA-approved vacuum cleaner.
Remove, disassemble, inspect, reassemble, and install the caliper, and note these items:
NOTE: Make sure that the caliper pins are installed correctly. Upper caliper pin B and lower caliper pin A are different.
If these caliper pins are installed in the wrong location, it will cause vibration, uneven or rapid brake pad wear, and
possibly uneven tire wear.  Do not spill brake fluid on the vehicle; it may damage the paint; if brake fluid gets on the paint, wash it off immediately with water.
 To prevent dripping brake fluid, cover disc onnected hose joints with rags or shop towels.
 Clean all parts in brake fluid and air dry; blow out all passages with compressed air.
 Before reassembling, check that all parts are free of dirt and other foreign particles.
 Replace parts with new ones as specified in the illustration.
 Make sure no dirt or other foreign matter gets in the brake fluid.
 Make sure no grease or oil gets on the brake discs or pads.
 When reusing brake pads, always reinstall them in their original positions to prevent loss of braking efficiency.
 Do not reuse drained brake fluid. Use only clean Honda DOT 3 Brake Fluid from an unopened container. Using a non-Honda brake fluid can cause corrosion and shorten the life of the system.
 Coat the piston, the piston seal groove, and the caliper bore with clean brake fluid.
 Use recommended greases in the front caliper set.
 After installing the caliper, check the brake hose and line for leaks, interference, and twisting.
Install inner brake pad with
its wear indicator upward.

3. Inspect the drive belt (see page 4-30).
4. Make sure no material is blocking the air flow to the
A/C condenser.
5. Check the dust and pollen filter. Replace it if it is clogged (see page 21-75).
6. Check for kinks or sharp bends in the A/C lines and hoses, which can greatly reduce system
performance. Replace A/C lines and hoses if they
are kinked or damaged (see page 21-8).
7. Start the engine, turn the air conditioning system on, and allow it to run for a few minutes and reach
stable operation.
 Check that the A/C operates at each position of the blower fan switch (except OFF). If the A/C
does not operate, refer to the symptom
troubleshooting.
 Check that the A/C compressor clutch (A) is engaged. The pressure plate should be rotating
at the same speed as the pulley. If the pressure
plate does not engage, refer to the symptom
troubleshooting.
 Check that the A/C condenser fan (B) and radiator fan (C) operate when the A/C compressor clutch
is engaged. If either fan fails to operate when the
A/C compressor clutch is engaged, refer to the
symptom troubleshooting.
 Check that the engine idle speed is correctly maintained when the A/C is switched on and off
and the A/C compressor clutch is engaged and
disengaged. Recommended PAG oil: SP-10
P/N 38897-P13-A01AH: 120 mL (4 fl·oz)
It is important to have the correct amount of refrigerant
oil in the A/C system to ensure proper lubrication of the
compressor. Too little oil damages the compressor; too
much oil reduces the cooling capacity of the system,
and can produce high vent temperatures.
 To avoid contamination, do not return the oil to the container once dispensed, and never mix it with other
refrigerant oils.
 Immediately after using the oil, reinstall the cap on the container, and seal it to avoid moisture
absorption.
 Do not spill the refrigerant oil on the vehicle; it may damage the paint; if it gets on the paint, wash it off
immediately.
Add the recommended refrigerant oil in the amount
listed if you replace any of the following parts: ........
.............. ............ ........
..............
........
.............. ............ ........
..............
A/C condenser .50 mL (1 2/3 fl·oz)
Evaporator .40 mL (1 1/3 fl·oz)
Line or hose .10 mL (1/3 fl·oz)
Receiver/Dryer .10 mL (1/3 fl·oz)
Leakage repair .25 mL (5/6 fl·oz)
A/C compressor .Since the oil separator is
equipped inside the compressor
for this vehicle, oil drainage is
unnecessary at the time of
compressor replacement.
