Lubrication System On-Vehicle Inspection

Warm up and stop the engine, then wait for 5 minutes.

Check that the engine oil level is between the low level and full level marks on the level gauge.
If low, check for engine oil leaks and add oil up to the full level mark.

NOTICE:

Do not fill with engine oil to above the full level mark.

HINT:

Engine oil is always being consumed when driving the vehicle.

Generally, engine oil is consumed at a rate of 1 liter every 3000 km, or 1 US qts. every 2000 miles.

In the following situations, oil consumption may increase and it may be necessary to add oil between maintenances.

1. The engine is new.
   
2. The oil quality is poor or the viscosity is inappropriate.
   
3. The engine speed or load is high, the vehicle is towing something or the vehicle is being accelerated and decelerated frequently.
   
4. The engine is idled for a very long time or the vehicle is frequently driven in traffic.
   

Check the oil for deterioration, water, discoloring or thinning.
If the quality is visibly poor, replace the oil.

Disconnect the oil pressure switch connector.

Using a 24 mm deep socket wrench, remove the oil pressure switch.

Install the oil pressure gauge.

Warm up the engine.

Check the oil pressure.

Oil Pressure:

At Idle	At 3000 rpm
25 kPa (0.3 kgf/cm2, 3.6 psi) or more	150 to 400 kPa (1.5 to 4.1 kgf/cm2, 22 to 58 psi)

If the oil pressure is not as specified, check the oil pump (COROLLA_ZRE142 RM00000259I03MX.html).

Remove the oil pressure gauge.

Apply adhesive to the end 2 or 3 threads on the oil pressure switch.

Adhesive:

Toyota Genuine Adhesive 1344, Three Bond 1344 or equivalent

Using a 24 mm deep socket wrench, install the oil pressure switch.

Torque:

15 N*m{153 kgf*cm, 11 ft.*lbf}

NOTICE:

Do not start the engine for at least 1 hour after installation.

Connect the oil pressure switch connector.

Check for engine oil leaks.
