If your like I am youve found over the years a rather consistent and recurring problem, you see, is that many projects get stalled for an hour or more rather regularly simply, because you find you don,t have some small, almost insignificant part like the correct size bolt, or fuze, or some washers etc.
now I generally visit salvage yards a few times a year looking for rebuild-able engine cores, rear differentials or body or interior components to repair cars, and most of the time I am with the guy who owns the car we will be working on, and hes going to be paying for the major parts, we are there to acquire.
but on those salvage yard trips I generally make it a point to bring along a 5 gallon bucket, and some tools, to collect small parts, that I pay for, for my personal use.
I learned long ago to bring a bucket and to pull fuses, relays, random bolts, accessory brackets,sensors, electrical connectors, electric fans , shrouds, and a million other small parts when you see them.
slow down, look around and don,t pass up small parts that won,t cost you a great deal, that you use frequently, like clamps, plastic clips, carburetor linkage,injector connectors, etc.
I also learned to look under car seats and under rugs in old car trunks as you occasionally find a few sockets, or old wrenches.
if you go to the check-out desk at the salvage yard with a 5 gallon bucket of assorted oily and greasy, dirty, small bolts, relays , electrical connectors radiator caps, t-stats, a couple engine fans, and maybe an alternator or water pump, and a couple large hands full of bolts, in an old 5 gallon bucket. you usually get charged a minimal fee for the total haul, and find you would have paid far more at the local hard ware store.
now youll most likely find you have to clean up the bolts in solvent and use a rotary stainless wire brush to clean the threads, and sort thru fuses and relays with a meter to find defective ones.
So how many of you guys grab a random assortment of small parts, bolts, sensors,brackets etc. when you go to a salvage yard.?
and how many times has your stash of assorted parts and your spare bolt bucket saved you trips to the local auto parts or hard ware store?
clutch fans have a viscus clutch that spins the fan based against the resistance its working against
the fans generally spin the fastest at about 2000-3000 rpm
,so from idle to about 2500 rpm fan speeds increase along with but not directly related too engine rpm,
much above that rpm the resistance won,t allow the fan speeds to increase nearly as fast as rpms increase
so the clutch fans do soak up some engine power , but not nearly as much as a solidly mounted fan would have.
generally the more blades on a quality clutch fan, the better it cools
I generally used to look for the clutch fans of caddys and buicks as many will mount to chevy water pumps with minimal or no mods
most were available from salvage yards dirt cheap in years past you ideally want something similar to this

don,t forget a matching fan shroud that matched the radiator and fan diameter,greatly increases cooling efficiency

most experienced mechanics have a 5 gallon bucket of assorted bolts and screws to fall back on when they can,t locate a fastener they break or misplace, youll need to clean used bolts with solvent and a wire brush, but having a bucket of spare fasteners is nearly mandatory, A visit to a local salvage yard with several wrenches and a bucket and a couple hours time, will generally allow you to collect a wide random selection ate a very reasonable price , now you may not find exactly every bolt diameter and length and thread size but you will generally find youve accumulated a good basic selection
https://www.boltdepot.com/Thread_detective_-_Metal.aspx
every mechanic should own a decent 12" caliper to measure the length of a bolt,
that may be missing on any particular application.
bolts used on any application, must not bottom out in a blind bolt hole if the bolt bottoms out it fails to clamp firmly
bolts that are not threaded into a blind hole should extend at least two to three times,
its diameter past the far surface too allow a washer and nut to be threaded onto the bolts extended end to supply clamping force.
so the depth of the item being clamped and the threaded area the bolt secures its threads too should generally be at least 1/4" deeper than the length of the bolt used,
and the threads should extend at least 2-3 times the bolt diameter into the threaded area,
before the bolts clamping force is applied to clamp the item being secured.
obviously you can get a rough measurement with the base of the caliper.
and when in doubt select a GRADE #8 fastener,
as they are significantly stronger than average garden variety hardware store bolts.
