hey guys the two fans in my 91 arent working. the larger fan will spin freely by hand but will then lock up causing the smaller fan to come closer to it. also when i start the car they spin but then get hung up on eachother after a couple seconds. i cant see anything thats physically broken. anybody know what the problem is? id really appreciate it!

sorry for the late response. the clutch fan pulls the ac fan in which causes them to stop. i'd really appreciate it if someone could help me out.

You need a new fan clutch. I've got a relatively new one if you want to buy it.

This "2nd" fan you speak of is non existent. That is your 'fan clutch'.

The big one with the shiny metal piece is your radiator fan and the metal piece is called the fan clutch. It goes out. The smaller one in front is for the AC condenser. That by itself isn't big enough to keep the car cool, it is there so you have a/c cold air at an idle.

I own a 89.

But I know that on my car the AC fan goes on the frontside of the radiator because it PUSHES air and the clutch fan is attached to the engine and sucks air.

I could be off, but isnt that AC fan on the wrong side of the radiator????

If its pushing, and the clutch fan is sucking,......then the AC fan is puching at the clutch fan and its getting sucked in.

Take that AC fan out of there.thats someones stupid wanna b after market mod that just blocks air flow and disrupts the amount of air the clutch fan sucks through.

it seams to me like you need a new fan. why dont you just get a new electric fan and free up some power? its also better for the car
