1. A method of controlling an operating temperature of existing vehicle engine cooling fan on and off cycles comprising:
installing a temperature sensor and switch assembly to a coolant hose of a vehicle engine, wherein said assembly includes means for mechanically connecting said assembly to said coolant hose;
electrically connecting said temperature sensor and switch assembly to one or more relays; and
electrically connecting said one or more relays to corresponding one or more cooling fans of said vehicle engine,
wherein said temperature sensor and switch assembly is pre-set to cycle on and off at pre-determined temperatures or temperature ranges.
2. The method according to claim 1, wherein said temperature sensor and switch assembly is pre-set to cycle on when a coolant temperature reaches about 170-300\xb0 F and to cycle off when said coolant temperature lowers to about 175-275\xb0 F.
3. The method according to claim 1, wherein said temperature sensor and switch assembly is one of an adjustable temperature sensor and switch assembly of fixed temperature sensor and switch assembly.
4. The method according to claim 3, wherein said temperature sensor and switch assembly is pre-set to cycle on when a coolant temperature reaches about 170-300\xb0 F and to cycle off when said coolant temperature lowers to about 175-275\xb0 F.
5. The method according to claim 1, further comprising:
electrically connecting an engine control unit of said vehicle engine between said temperature sensor and switch assembly and said one or more relays.
6. A system for controlling an operating temperature of existing vehicle engine cooling fan on and off cycles comprising:
a temperature sensor and switch assembly, said assembly includes means for mechanically connecting said assembly with an engine coolant hose;
one or more relays in electrical communication with said temperature sensor and switch assembly, said relays having means for electrically communicating with one or more respective cooling fans,
wherein said temperature sensor and switch assembly is pre-set to cycle on and off at pre-determined temperatures or temperature ranges.
7. The system according to claim 6, wherein said temperature sensor and switch assembly is pre-set to cycle on when a coolant temperature reaches about 170-300\xb0 F and to cycle off when said coolant temperature lowers to about 175-275\xb0 F.
8. The method according to claim 6, wherein said temperature sensor and switch assembly is one of an adjustable temperature sensor and switch assembly of fixed temperature sensor and switch assembly.
9. The system according to claim 8, wherein said temperature sensor and switch assembly is pre-set to cycle on when a coolant temperature reaches about 170-300\xb0 F and to cycle off when said coolant temperature lowers to about 175-275\xb0 F.
10. The system according to claim 6, wherein an engine control unit of said vehicle engine is electrically connected between said temperature and switch assembly and said relays.
