6. RADIATOR AND CONDENSER CLEANING
A clogged radiator raises the compressor's temperature to the point of shutting it down due to overhea-
ting. Before starting to clean proceed as indicated in item 1.
To clean the radiator and the condenser externally (Figure 17.10), use compressed air from the outside
to the inside.
To clean the radiator more thoroughly, brush its inner bottom surface.
Note: Do not use a metal brush to clean the radiator or condenser, avoid crumpling the cooling fins.
