The electric cooling fan is controlled by the Engine Control Module (ECM) through the cooling fan relay based on inputs from the following components: - The engine coolant temperature (ECT) sensor. - The intake air temperature (IAT) sensor. - The A/C selector switch. - The A/C refrigerant pressure sensor.
Staff bags are big enough to hold everything a pro would need. In fact, they are usually designed after the custom golf bags pros use, so they are larger and heavier than regular golf stand bags. Staff bags are often made of leather and have large pockets. They have space for a full set of 14 golf clubs.
According to the USGA, a golfer is allowed to have 14 clubs in his bag. This may include three woods (driver, 3-wood and 5-wood), eight irons, (3-9 iron and pitching wedge), and putter. These are the standard 12 clubs in many golf bags. If the golfer starts with a number of clubs in his bag less than 14, he can add to the number of clubs until he reaches 14.
