CLEAN, CHECK RADIATOR FINS AND AFTER COOLER FINS

If compressed air scattered around dust and debris, there is danger of injury. Always wear protective equipment such as
protective glasses and mask.
If the radiator fins become clogged or bent, this may cause
overheating of the engine, so always clean or carry out inspection
and take the necessary actions.
Cleaning can be carried out by using jets of air, steam, or water,
but be careful not to let the nozzle contact the fin.
When using compressed air or steam, keep the nozzle at a right
angle to the radiator and after cooler.
Examine the rubber hose, and if any cracks or brittle places are
found, replace the hose. In addition, check also for loose hose
clamps.
NOTICE
If steam jet nozzle (1) is brought too close to fins (2), the fins can be
damaged, so keep a good distance in between when cleaning.
Use the following values as a benchmark.
Jet pressure: Lower than 9.8 MPa (100 kg/cm
Nozzle diameter: Less than 2 mm (0.08 in)
Distance between nozzle and fin (A): More than 100 mm (4 in)
