    Finding a fan shroud for a 200 cid six is like looking for a needle in a haystack (Can't find the haystack, either)

    I installed one by looking up the generic part number of the 20" radiator, and looking to see what fan shrouds fit that radiator. Besides the Maverick 200 six, it also fit many Mustangs with 289/303/351W engines.
    After studying the measurements and geometry of the Mustang applications and the Maverick, I selected:
    Mustangs Unlimited part number: F2104 01 Ford part number C9ZZ-8146

    Installing: I rotated it 180 degrees, re-located the bottom two bolt holes, fashioned out of some thin aluminum - a piece to cover the radiator hose cut-out (now on the driver's side top), and then screwed the aluminum piece in with 2-56 screws/washers/nuts. (Spayed black before mounting). SEE ATTACHED PICTURES

    I'm using an aluminum "cool fan", and selected a new fan spacer to set the fan blade just inside the round opening.

    Looks great!
    Can you tell me what radiator you're using? Where did the fan come from and what size is it?
    I'm rebuilding my 200 with A/C and am trying to decide between doing a better fan and adding a shroud or going with an electric fan. Thanks!

    I'm at work, so I don't have access to the part numbers:
    I bought the radiator (new) on e-bay "Superior" brand. Look under Maverick or Ford Maverick.
    The flex-fan is a "Flex-a-lite". I don't remember if it's 17" or 18" (I measured the stock fan, and used that diameter).
    Also, I used a different fan spacer. ( I believe a 1")
    The set-up has plenty of flow!!! In fact, it really helps cool the header heat!

    Mechanical vs Electric fan?
    There are always trade-offs. The conversion from mechanical energy to electrical energy, and then back to mechanical energy (engine -alternator-electric fan) has a high degree of energy loss - and creates heat in the process. But, the cooling process is controlled - fan is only on when demanded. But, if the thermostat switch or the electric motor goes out - engine quickly over-heats.
    With a mechanical system - the fan is always on...not a bad thing, but is always using energy - unless, a thermal " fan clutch" is used.
    I used a "budget" aluminum fan (much lighter than stock). But, there are fan blade types that flatten out at high rpm - when there is enough air flow from forward motion of the car, that the fan isn't needed.

    I looked up - the radiator is Performance #329.

    Yeah and your electric fan won't be turning for all to long either without the belt turning the alt..especially with one of those Taurus fans.you'll be walking in no time at all.

    I never had that problem...but a broken belt you would be walking either way.
    don't understand your point, that fan came on how many Taurus cars...:huh:
    mine was wired through a 20 amp fuse to a Volvo relay.

    ...a good mechanic would be keeping an eye on those things...periodic maintenance & inspection.
    Relays are rated in MTBF (Mean time before failure) in # of contacts (opens/closes). How do you count?
    ...I was just saying.....
