oil level ACURA NSX 1997 Service Repair Manual

The numbers in the middle of the API Service label tell

you the oil's SAE viscosity or weight. Select the oil for

your vehicle according to this chart:

Ambient Temperature

An oil with a viscosity of 10W - 30 is preferred for

improved fuel economy and year-round protection in the

vehicle.

You may use a 5W - 30 oil if the climate in your area is

limited to the temperature range shown on the chart.

Installation (cont'd)

17. Apply liquid gasket to the head cover gasket at the

eight corners of the recesses.

NOTE:

• Use liquid gasket, Part No. 08718 - 0001 or 08718

- 0003.

• Check that the mating surfaces are clean and dry

before applying liquid gasket.

• Do not install the parts if five minutes or more

have elapsed since applying liquid gasket. Instead,

reapply liquid gasket after removing old residue.

• After assembly, wait at least 20 minutes before

filling the engine with oil.

Apply liquid gasket to

the shaded areas.

18. When installing the cylinder head cover, hold the

head cover gasket in the groove by placing your fin-

gers on the camshaft contacting surfaces (top of the

semicircles).

Once the cylinder head cover is on the camshaft

holder, slide the cover slightly back and forth to

seat the head cover gasket.

NOTE:

• Before installing the cylinder head cover, clean

the cylinder head contacting surfaces with a

shop towel.

• Do not touch the parts where liquid gasket was

applied.

• Replace the washer when damaged or deterio-

rated.

Engine Oil

Inspection

1. Check engine oil with the engine off and the car

parked on level ground.

2. Make certain that the oil level indicated on the

dipstick is between the upper and lower marks.

3. If the level has dropped close to the lower mark,

add oil until it reaches the upper mark.

CAUTION: Insert the dipstick carefully to avoid

bending it.ProCarManuals.com
