HELP Cooling system problem HELP

[ColbsE30]

Alright so just a couple months ago I went for a ride in my E30 and accidentally left the park brake on for about half a mile and in result it knocked my lower radiator hose into my power steering pully and split then horribly overheated. When she overheated the water pump went out on me, so I replaced the water pump and put a new thermostat in. After that the lower radiator hose split 3 more times and there were 3 more overheats because my power steering pully for some reason sat right in front of where the hose comes out of my radiator and now matter how I would route it it would split. So now I removed all of my power steering.
My temperature gauge when I turn her on gets to normal operating temperature but then will go to half then to 3/4 then back to half and then it'll keep bouncing around between half and all the way to the red. I notice it goes down when I start driving at higher speeds, but only a little bit then gets hot again when I slow down or idle.
From another post I was told that my fan clutch is the issue. I just replaced that today, and guess what? Shit still isn't working and the same problem is reoccurring.

And another thing, my auxiliary fan isn't working at all. It's a newer aux fan, so I'm thinking it's a switch or sensor that's wrong with it. But could the aux fan be an issue that's causing her to act like that and overheat?

PLEASE anything to help. I have work all week and no ride there because of this.

What in the world does leaving your parking brake on have to do with making your car overheat? That seems pretty irrelevant to me. Parking brake just drags on the rear of the car making it a little harder to drive.

First, if you're shredding hoses on the PS pump, check your driver's side motor mount, its more than likely collapsed to allow the pump to hit the hose. Unless you have the wrong size or an enlarged hose somehow, or the pump has managed to move without throwing the belt off, that will be your issue.

For the overheating, how bad did it get? If it got hot enough on four separate occasions and still tries to overheat, I'd be willing to bet you either popped a head gasket or cracked the head. Pressurize the cooling system to see if it holds. If not, its leaking somewhere.
