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.
Fourteen clubs are the maximum allowed in one player's golf bag during a round played under the Rules of Golf. Any number below 14 is fine, but more than 14 is not. Also, those 14 clubs cannot be changed during the course of one round. You must finish with the 14 you started with. (There are some exceptions in the case of a club breaking.) However, if you begin with fewer than 14, you may add clubs during a round as long as no delay is caused and as long as the club(s) added are not borrowed from another golfer. To reiterate: If you are playing under the Rules of Golf, you can have no more than 14 golf clubs in your bag.
