Mike its an 8 blade fan. No clutch.
The center of the blades are right at the edge of the shroud. So i think im good there

Ive not opened it ip just yet. So don't know what tstat is in it yet.

I am thinking changing the thermostat ....simply because is old qnd unknown temps
. If i do..i will change stat and flush the system and upgrade coolant.at same time.

I am preparied to park to car during the high temp summer months. Southern Arizona you know
But ambient temps are nice right know.
