4. Remove the fuel cooler “1”.
Checking the fuel rail and fuel
injector
1. Check the fuel rail. Replace if cracked or
deformed.
2. Check the electric performance of the
fuel injector See “Checking the fuel injec-
tor” (5-17).
3. Measure the volume injected by the
injector. See the “Fuel Injection Meter
Operation Manual”.
Do not use gasoline when measuring the
fuel injection volume. Otherwise, the cyl-
inder could be damaged, which can cause
a gasoline leakage. Make sure to follow
the instructions for operation of the fuel
injection meter.
TIP:
• When measuring, obtain a result from the
average of 4 measurements.
• It is not possible to obtain correct measure-
ments under disparate test conditions.
Make sure to fully charge the battery.
• The cylinder is graduated in increments of
2.5 cm
3
(2.5 cc).
• Make sure to comply with the laws and reg-
ulations of the region when disposing of the
used test fuel.
Installing the fuel cooler
1. Install the fuel cooler “1”.
2. Connect the fuel hoses “1” and “2”, and
then fasten them using the clamps “3”.
3. Connect the cooling water hoses “4” and
“5”, and then fasten the cooling water
hose “5” using the clamp “6”.
