[DeTomaso] Replacing stock cooling fans

Having one sucker and one pusher act on the same segment of the radiator is
not necesssarily twice as good as having only one of them. You may only be
straining the electrical system more with little or no cooling advantage.
I'd suggest getting two fans that work on their own and skip the third fan.
One reason for putting fans on both sides of the radiator would be if you
couldn't fit two of them side by side but I think the ones most people use
fit side by side and avoid the cooling pipes at the same time.

Ok, thanks for all the help

I have the water tubes passing quite close to the radiator so I might go for
a blower/pusher. I have a single puller today mounted on the left side of
the radiator because of the same reason.

I might keep the puller and mount a "double" blower/pusher. I guess that
would be more than enough or do I block the air flow to much if I keep the
puller?

Correct.

Blower is also called 'pusher' and puller is also called 'sucker'.

Flex-a-lite has two-fan assemblies in both styles. They have
apparently changed their part numbers from a couple of years ago. The
bare units (without thermostats or speed controller) are now 420
puller and 440 pusher.

See these pages:

DO NOT install with the through-the-core tie wraps. ONLY use rigid
brackets.
