X10 Although surface layer materials of rubber hoses have excellent weathering resistance, heat resistance and
resistance for low temperature brittleness, they are likely to be damaged chemically by brake fluid, battery
electrolyte, engine oil and automatic transmission fluid and their service lives are to be very shortened . , It
is very important to keep the-,hoses free from before-mentioned fluids and to wipe out immediately when
the hoses are adhered with the-fluids.
Since resistances for heat or low temperature brittleness are gradually declining according to time
accumulation of hot or cold conditions for the hoses and their service lives are shortening accordingly, it is
necessary to perform careful inspection frequently when the car is used in hot weather areas, cold weather
area and/or a driving condition in which many steering operations are required in short time. Particularly
continuous work of relief valve over 5 seconds causes to reduce service lives of the hoses, the oil pump
ASSY, the fluid, etc . due to over heat .
So, avoid to keep this kind of condition when servicing as well as driving.
