Loctite is your friend.

As you can with most bolts but the factory installed it for a reason I am sure if they thought they did not need it the bean counters would have binned it.
Agree on the loctite.
When I look up the bolt online I don't see a washer anywhere. Would you mind pushing me in the right direction? 
Have you got a Haynes manual if not you should as it is a wealth of information.
As you are pulling the radiator now is the time to replace the radiator hoses, water pump, and timing cover seal while you have the radiator out.
The washer is on this site part number Tam2020 for $3.90.

If in doubt, flat out. Colin Mc Rae MBE 1968-2007.

Ok so this is my third time editing this post. I do have a 1275 A+ engine based off of the dipstick and the alternator brackets. Thank you for being so helpful

I can only find videos on how to pull the radiator, not on how to put it back in. is it just a put it back the opposite way you took it out or is there something I should watch out for?

Yeah, I am thinking that the bolt being wedged between the pulley and radiator has held in the pulley. What confuses me is how the car has been running fine with that like that

If your fanbelt is lined up correctly, there is no side-load on the pulley so there is no reason for it to walk off the end of the crank - it's purely a rotational motion to drive the ancilliaries.

It's keyed to the crank with a woodruff key so it won't spin, and the fit is a gnat's less than interference and can sometimes need a puller to get it off if there's sticky old oil between the surfaces.

Blue Loctite is your friend, in this case Red Loctite is not your friend.

Don't forget to replace the lock tab washer as well.

The pulley is keyed to the shaft so it will not slip, also that is needed to keep the timing marks in the correct location.

I kept hearing a rattling sound when I was sitting still and I finally found this between the bottom pulley and my radiator. Any ideas where it came from and how I should go about repairing it? (I am not sure this matters but i Have a 1275 cc engine)
