Radiator-regulator frame
The vehicles are equipped as standard with a radiator frame that surrounds the fan at a short distance from it. The frame needs careful and thorough adjustment so that the fan does not touch the radiator frame when the engine is running, three inappropriate distances can lead to the destruction of the frame. The mounting points of the radiator frame are located so that it is possible to install both in height (dimension A), and in width (dimension B).
Installation and adjustment measurements of the radiator frame
Distance "a" from the radiator to the fan on 6-cylinder engines is 50 mm. On 8-cylinder engines - 20 mm to the fan casing.
A. 6-cylinder engines 28 mm; 8-cylinder engines 20 mm.
B. 15 mm (all engines).
