I dont see the blades broken
they are curved and not in the pic cause the angle of camera
they flex out flat at speed
IMHO,temps creeping up like that can be normal,if the rad is not puking water and boiling over,its not over heating
a recover system is for this reason, the collent expands when hot
feel the core of the rad when good and warm,feel for any cool spots in the core,this will be clog area in the tubes restricting flow
also need a good spring in the lower hose,I will most likly get flamed for that comment but..it cant hurt in summer traffic
a new replacment rad from napa has been the best thing I have done for the last 3 trucks I had
I bump it up to an 8 vane pump for non a/c sb with a 3 row rad and the 7 blade 18" fan
I run a new clutch with the spring on it,that is a thermo clutch and will use the temps to lock and unlock the fan blade
wp and correct size pullys have a lot to do with cooling also
it not good to lay the clutch part shaft down like in the pic either
something about the viscus fluid leaking out and the clutch not working properly
which you should check for side play and viscosity
that old rad has ssen better days i am sure
