9. Start the engine and warm up the engine by idling.
10. After the engine warms up, perform the following steps. At this time, be careful of the coolant
temperature to prevent overheating.
1. Run the engine at
approx. 2,500 rpm
for
5 min
.
2. Run the engine at
approx. 3,000 rpm
for
5s
, then idle.
3. Repeat step 2 4-5 times.
11. Stop the engine, and inspect the coolant level after the coolant temperature decreases. If it is low, repeat
steps 7 thru 10.
12. Inspect for engine coolant leakage. (See
ENGINE COOLANT LEAKAGE INSPECTION [LF]
.)
ENGINE COOLANT LEAKAGE INSPECTION [LF]
1. Inspect the engine coolant level. (See
ENGINE COOLANT LEVEL INSPECTION [LF]
.)
2. Remove the cooling system cap.
3. Clean the installation parts of the cooling system cap.
4. Install the
SST
and a radiator cap tester to the coolant reserve tank filler port.
5. Apply pressure using the radiator cap tester.
Pressure
122.6 kPa {1.25 kgf/cm
2
, 17.8 psi} [1 min]
WARNING:
Never remove the cooling system cap or loosen the radiator drain
plug while the engine is running, or when the engine and radiator
are hot. Scalding engine coolant and steam may shoot out and
cause serious injury. It may also damage the engine and cooling
system.
Turn off the engine and wait until it is cool. Even then, be very
careful when removing the cap. Wrap a thick cloth around it and
slowly turn it counterclockwise to the first stop. Step back while the
pressure escapes.
When you are sure all the pressure is gone, press down on the cap
using the cloth, turn it, and remove it.
CAUTION:
Applying more than 122.6 kPa {1.25 kgf/cm
2
, 17.8 psi} can
damage the hoses, fittings, and other components, and cause
leakage.
